785 Organic Chemistry. Derivatives of Di-isocrotyl and Di-isobutenyl. By S. POUOR~ELSKY (Chem. Cent?.., 1899, i, 773-775 ; from J. Russ. Chem. Xoc., 1898, 30, 9'77-992).-Isobutylene, prepared by the action of alcoholic potash on isobutylic iodide, combines with bromine to form ieobutylenic bromide, and this compound, when treated by Butleroff's met,hod (Krit. Zed. Chem., 1870, 524) yields isocrotylic bromide. This boils a t 9 1 - 9 2 O , has a sp. gr. 1.3544 a t 0' or 1.3254 at 16.5', and coefficient of expansion 0.00244 between 0' and 16.5'. Di-iso- crotyl, prepared by the action of sodium on isocrotylic bromide, boils at 132-134' and melts at 6'. CMe,Cl*CH,*CH,* CMe,Cl, obtained by the action of hydrogen chloride on di-isocrotyl, crystal- lises in elongated leaflets, melts at 64', and is soluble in alcohol, ether, benzene, light petroleum, or chloroform ; hydrogen chloride is not eliminated by the action of alcoholic gotash. Di-isocrotplic bromide crystallises in leaflets, melts at 68*5-69', and is soluble in alcohol, ether, benzene, light petroleum, or chloroform ; it is much less stable than the chloride and gradually changes into a dark liquid of penetrating odour.By the action of dilute sulphuric acid (3 vols. acid to 2 vols. water) on di-isocrotyl or of potassium carbonate on di-isocrotylic bromide, di-isocrotylic oxide is obtained ; it boils at 113' under 786 mm. pressure, has a sp. gr. 0.8272 a t 0' or 0-8113 at 20', coefficient of expansion 0*000976 between 0' and 20°, and is easily solnble in alcohol, ether, light petroleum, benzene, or chloroform.Di-isocrotylic bromhydrin, CMe,Br-CH,*CH,*UMe,* OH, prepared by the action of hydrogen bromide on di-isocrotylic oxide, melts at 77-78', and, when heated, decomposes into di-isocrotylic bromide and di-isocrotylic oxide. Bi-isocrotylic iodhydrin is much less stable than the bromhydrin and melts a t 70-71'. By the action of dry hydro- gen chloride on di-isocrotylic oxide, the dichloride is formed. When the oxide is heated with a 1 per cent. solution of hydrochloric acid at 180-190°, di-isocrotyl is obtained, the unstable glycol, OH*CMe,*CH,*CH,*CMe,*OH, being probably an intermediate product of the reaction. Di-iso- crotylic oxide is not affected by heating with water at 190-195". Di-isobutenyl, CH,:CMe*CH,*CH,*CMe;CH,, prepared by the action of sodium on isobutenylic chloride, boils at 113-1 14' and when heated with sulphuric acid yields di-iaocrotylic oxide, the change in this case being also due to the formation of the unstable glycol.By the action of hydrogen bromide on di-isobutenyl, di-isocro tylic bromide is formed.

This readily combines with bromine, forming the bromide, CMeEtBr*CH,Br, which has a sp, gr.1.6921 at 0" and 1.6638 a t 21'. P-B~om-a-metl~yZetl~?/Zet~yZene, CMeEt :CHP,r, obtained by the action of alcoholic potash on the bromide, boils a t 117-11s" under 767.7 mm. pressure, and has a sp. gr. 1.2668 a t 0' and 1.2423 a t 20'. A hydro- carbon, CloH18, is obtained by treating the bromamylene with sodium ; it boils at 167-170°, and bv the action of dilute sulphuric acid (3 vols. of acid t o 1 of water) firms the corresponding diteitiary-y-oxide, CMeEt* CH, bMeEt, cHo>O, probably by means of the intermediate production of the glycd. The oxide boils a t 159-161°, has a pleasant, camphor- like odour, and, by the action of hydrogen bromide dissolved in light petroleum, yields a compound, C,,H,,Br,.

Compare this vol., i, 748, and Mokiewsky, this vol., i, 729).-The best yields of a-dihalogen-substituted ethylenes are ob- tained by treating the alcoholic solutions of the acetates of a-trihalogen- substituted alcohols with zinc shavings. Under these conditions, tri- chloret h ylic acetate, COMe OC.H,* CCI,, forms unsymmetrical dichlor- ethylene, CCl,:CH,, and a small quantity OF a gas which combines with bromine, and is probably chlorovinyl.

Action of Bromine on Isobutylic Bromide in presence of Alu- minium Bromide and Chloride. By A. MOUNEYRAT (Compt. rend., 1899, 129, 226-22S).-When bromine acts on isobutylic bromide in presence of aluminium bromide, the products are (1) a small quantity of isobutylenic bromide, (2) a large quantity of the tribromisobutane, CMe,Br*CHBr,, a colourless liquid of sp. gr, 2.188 a t 16', which boils E.

No variations in the relative proportions of isobutylic bromide and bromine led t o a satisfactory yield of isobutylenic bromide. If, however, a small quantity of aluminium chloride is used instead of the bromide, the isobutylenic bromide, CMe2Br*CH2Br, which boils and decomposes a t 148-149’ under normal pressure, is obtained in quantity amounting to 50-55 per cent. of the calculated yield. Tribromisobutane, CMe2Br*CHBr2, when treated with bromine in presence of aluminium chloride or bromide, yields 65-70 per cent. of the theoretical yield of tetrabromisobutane, CH,Br*CMeBr*CHBr, ; this has a sp. gr. 2.557 at 16*, and boils a t 159-163’ under 12 mm.pressure.

By EDMOND JANDRIER (Compt. rend., 1899, 128, 1407--1408).-The oxycelluloses, and especially that obtained by the oxidation of cotton with potassium chlorate (Vignon's process), yield colour reactions when a solution or suspension is mixed with a phenol, and concentrated sulphuric acid is added so that it forms a layer below the organic mixture; the coloration is developed a t the junction of the liquids. A golden yellow is produced with phenol ; varying shades of violet are obtained with a-naphthol, menthol, thymol, and the alkaloids morphine and codeine ; P-naphthol, quinol, and resorcinol give brown shades, and gallic acid gives a green coloration at the junction, which changes to violet in the sulphuric acid.Formaldehyde, gum arabic, and the aldoses give colour reactions when similarly treated, Nitromalonic Aldehyde. By HENRY €3. HILL and JOSEPH TORREY, jun. (Amer. Chem. J., 1899, 22, 89--110).-The authors find that the colourless compounds, C,H,NO,K + H20 and C,H,NO,Na + H,O, obtained respectively as final products of the action of potassium and sodium nitrite on mucobromic acid (Hill and Sanger, Abstr., 1883, 47), are salts of nitromalonic aldehyde, CHO*CH(NO,)*CHO. This aldehyde, obtained by adding an ethereal solution of hydrogen chloride to the silver salt suspended in absolute ether, crystallises from light petroleum in feathery aggregates of prisms and melts at 50-5 1' ; its molecular weight was determined cryoscopically, using benzene as the solvent, I n aqueous solutions, it is slowly decomposed at the ordinary temperature, more rapidly at 45-50', giving rise to 1 : 3 : 5-trinitrobenzene and formic acid.The a d , C,H,NO,:NPh, obtained on adding aniline hydrochloride to an aqueous solution of the sodium salt, crystallises from alcohol in lustrous, yellow scales, and melts a t 143-144O ; if aniline is employed instead of its hydro- chloride, the dianil, C,H,NO,(NPh),, is obtained in the form of brilliant yellow needles. The paratolils, C,,H,,N,O,, and ClVHl7N,O,, prepared similarly from paratoluidine, melt respectively a t 176-177" and 138'. The p?~enyZhydraxone, C9H9N303, formed on adding phenylhydrazine hydrochloride to a solution of sodium ni tromalonic aldehyde, forms yellow needles and melts and decomposes a t about 101'; the diphenyl- hydraxone, C,,H,,N,O,, obtained by adding dilute alcoholic phenyl- hydrazine to the sodium derivative of the aldehyde and passing carbonic anhydride through the solution, is a dark-red, unstable, crystalline substance which melts and decomposes a t about 98*, and yields a stable, crystalline sodium derivative, Cl5H1,N,O,Na, and a lead salt, (C15H,,N,0,),Pb.

P-Nitroisoxaxole, C3H2N203, formed on adding hydroxylamine hydro- chloride (1 mol.) to concentrated, aqueous sodium nitromalonic aldehyde, crystallises from a mixture of ether and light petroleum in aggregates of transparent, rhombic plates, and melts a t 46-47' ; if this action is carried out in presence of an equivalent quantity of sodium carbonate or sodium hydroxide, transparent, yellow crystals of the sodium derivative, C3H+N30+Na, of niti*omaZonic diatdoxime are obtained; the corresponding salver salt, C3H4N,0,Ag, is a pale yellow, microcrystalline powder ; the dioxime could not be isolated.Nitromatonic aldehyde andoxime, NPh:CH*CH(NO,)*CH:N*OH, formed on adding aniline hydrochloride t o a solution of the sodium derivative of the dioxime, crystallises from alcohol in yellow, globular aggregates, and melts at 162O ; i t can also be obtained by acting with hydroxylamine on the monanil of nitromalonic aldehyde (m. p. In alkaline solution, nitromalonic aldehyde readily condenses with acetone to form paranitrophenol, and similar condensation products are formed with ketonic acids and other ketones.Azelaone. By W. MILLER and A. TSCHITSCHKIN (Annalen, 1899, 307, 375-383. Compare Mager, Abstr., 1893, i, 658, and Derlon, Abstr., 1898, i, 638).-The best yield of azelaone is obtained when small quantities of azelaic acid are distilled with an equal weight of soda lime ; it boils a t about 205O.

Compare Abstr., 189'7, i, 236)-The compounds of acetylacetone with the sesquioxides crystallise in similar forms, melt without decomposi- tion, and are more or less volatile; when crystallised from chloro- form, they all retain 2 mols.of the solvent ; their molecular weights, determined by cryoscopic methods, correspond with those required for the simple formula R(CHAc,),. The ferric derivabive, Fe( CHAc,),, prepared by digesting ferric hydroxide with excess of acetylacetone, forms a bright red, crystalline precipitate almost insoluble in water ; it is soluble in the ordinary organic solvents, can be crystallised from benzene and melts at 184". The rnanganic derivative crystallises from ether in shining, black crystals and melts at 1 7 2 O . The cobaltic derivative melts a t 240°, and is more stable than the preceding salts ; its solutions in organic sol- vents are intenssly green, and it separates from these in black crystals.The c?mmic derivative is a reddish-violet salt melting a t 214' and boiling at 340" without decomposition ; the vapour is green, 143-144').

When treated with phosphorus pentachloride, it yields a dichlovo- nitrib, CH,Cl* CHCl* CH,* CN, which boils at 11 3-1 14' under 25 mm.pressure, and has a sp. gr. 1.314 a t Oo. py:DichZorobzLty&c acid, CH,Cl* CHGl* CH,. COOH, obtained from the nitrile by hydrolysis, melts at 49-50'; its ethylic salt boils a t 206-209° under 750 mm., and at 92' under 14 mm. pressure. Identification and Separation of Fatty Acids by means of Tetrachloroquinol. By Lours BOUVEAULT (Compt. rend., 1899, 129, 53-56).-The identification and separation of the fatty acids by means of the compounds which they form with tetrachloroquinol is attended with considerable advantages, the amides, anilides, paratoluidides, and phenylhydrazides, which have been used for these purposes, being in many cases difficult to purify, whilst the regeneration of the acids therefrom is often very troublesome.When tetrachloroquinol is heated in a reflux apparatus with excess of an acid chloride, R*CO*Cl, it reacts with I and 2 mols. of the latter to form monacid and di- acid derivatives respectively. The di-acid derivatives, C6Cl,(O*C0 OR),, are very soluble in ether, benzene, chloroform, hot methylic or ethylic alcohols, but less so in light petroleum, and insoluble in water. They are stable, well crystallised substances, which are not acted on by dilute acids and alkalis ; warm alcoholic potash rapidly hydrolyses them with regeneration of the acid. The monacid derivatives, OH* C,Cl; O*CO*R, are also well crystallised, and are distinguished from the preceding compounds by their solubility in dilute alkalis; they are also more soluble in alcohol, and less soluble in light petroleum than the di-acid derivatives.The di-acid derivatives of acetic (245'), propionic ( 160°), butyric (1 3'7O), and a-dimethylisocrotomc (1 30-1 34") acids have the melting points indicated; the monacid derivative of the last named acid melts at 132'. Action of Pyruvic Acid on Malonic Acid: Synthesis of Itaconic Acid. By KARL GARZAROLLI-THURNLACKH (Mornutd., 1899, 20, 467--479).-When pyruvic and malonic acids, in molecular pro- prtion, are dissolved in glacial acetic acid and the solution is warmed on a water-bath until carbonic anhydride is no longer evolved, itaconic and citramalic acids are obtained, the former being the principal pro- duct, A third acid, isomeric with citramalic acid, also seems to be produced, but no evidence was obtained of the formation of citraconic acid in the reaction, The production of itaconic to the exclusion of citraconic acid makes it probable that pyruvic acid reacts in tho enolic C.H.

By W. MILLER (Annalen, 1899,307,384-386). -3thyZic cmelate is a colourless, somewhat viscous liquid, having a slight, agreeable odour, and distilling a t 291-292'; its sp. gr. is 0,9906 a t Oo/Oo and 0.9766 at 15'/0'. Methylic Hydroxymethylenecyanacetate and some of its Homologues.8 y E. GRhUOlRE DE BOLLEMONT (compt. rend., 1899, 129, 50--53).-According to Claisen (Abstr., 1897, i, 592), hydroxy- methylene derivatives of the type of ethylic hydroxymethyleneacetoacet- ate may be regarded as formic acid in which oxygen has been replaced by a carbon atom united to two negative groups. Such compounds behave, in fact, like strong monobasic acids, and the introduction of a more negative radicle, such as cyanogen, in place of the acetyl group might be expected to lead to the formation of compounds of a still more pronouncedly acid character. The alkylic hydroxymethylenecyan- acetates, obtained by hydrolysis of the corresponding methoxy- and ethoxy-methylenecyanacetates (Abstr., 1899, i, 736), have proper- ties which show that this is the case.These compounds are strong monobasic acids which displace carbonic and acetic acids from their salts, and are converted by the action of ammonia and aniline into the corresponding amido- and anilido-methylenecyanacetates. They are slightly soluble in water, more soluble in alcohol and ether, and undergo more or less decomposition when distilled under diminished pressure. Their aqueous solutions give an intense orange-brown coloration with ferric chloride. Methylic hyllroxymethylenecyanacetute, OH*CH:C(CN)*COOMe, is a crystalline substance of pungent odour and melts at 136-13'7'. The value found €or its affinity coefficient (K= 1.505) shows that it may be compared with the chloracetic acids. The barium salt crystallises with lH,O and is soluble in hot water, but only slightly so in alcohol or ether; it becomes anhydrous at 150' and at the same time acquires a yellowish tint.The copper salt, with 2H,O, forms pale green crystals, which become anhydrous and darken in colour at 110'. The silver salt crystallises in silky tufts and is converted by the action of methylic iodide into methylic methoxymethylenecyanacetate. Etlu~lic hydroxy- methylenecyanacetate, OH*CH:C(CN)*COOEt, was obtained as a colourless oil, and also in the form of transparent plates melting at 68-69'. Amylic ?~~drt.oxymetlzyZenecyancce~ate could only be obtained Conversion of Alkylic Dibromacetoacetates into Mesaconic Acid and its Homologues. By W. SSEMENOFF (Chem. Centr., 1899, i, 781-784; from J. Buss. Chent.Xoc., 1898, 30, 1009--1~3O).-The paper contains a criticism of the various theories of the mechanism of the reaction whereby alkylic dibromacetoacetates are converted into mesaconic acid and its homologues. By boiling ethylic methyl- R. H. P. Ethylic Azelate. M. 0. F. in an impure state as an uncrystallisable oil, N. L.702 ABSTRACTS OF CHEMICAL PAPERS. acetoacetate with bromine (2 mols.) and water as long as carbonic anhydride is evolved, an oil containing mono-, di-, and tri-bromo- methyl ethyl ketone is obtained. By heating this oil with a 10 per cent. solution of sodium carbonate and acidifying the product, isocrotonic acid, or probably a mixture of this acid with crotonic acid, is formed. According t o Faworsky’s first theory of the method of formation of unsaturated acids from dichloroketones, a-bromobutyric acid should be the first product of the above reaction, but by the action of sodium carbonate this acid forms a-hydroxybutyric acid, and not isocrotonic acid.Faworsky’s second theory is adopted by the author, and the conversion of alkvlic dibromacetoacetates into mesaconic .I acid is represented as follows : CHBr,. C(OH):CMe* COOEt - HBr = O<FHBr = COBr*CH:CMe*COOEt. CMe* COOEt The intermediate unstable oxide and the acid bromide cannot be isolated, but by the action of an alcoholic instead of an aqueous solu- tion of an alkali carbonate, the ethoxy-compound corresponding with the acid bromide may be obtained if the action is stopped before the alkali hydroxide has completely hydrolysod it. These ethoxy- compounds are also formed in large quantities by the action of alcoholic potash on alkylic dibromalkylacetoacetates at a low tem- perature, and may be removed by distilling in steam.The neutral compound obtained in the preparation of dimethyl - mesaconic acid from ethylic dibromisopropylacetoacetate boils at 240-241°, and consists mainly of diethylic dimethylmesaconate, whilst that formed in the preparation of ethylmesaconic acid from ethylic dibromopropylacetoacetate is diethylic ethylmesaconate. By the action of alcoholic potash on ethylic dibromethylacetoacetate , an oil is formed which, when hydrolysed, yields me thylmesaconic acid, and when only 2 mols. of potassium hydroxide are used, this com- pound is the main product of the reaction. According to the author, the boiling point of Faworsky’s dichloroketone, COMe*CCl,* CH,Me, in- dicates that it probably contained the compound CMeCl,.CO*CH,Me to some extent, and this would explain the formation of both angelic and a-ethylacrylic acids. By the action of alcoholic potash on alkylic dibromalkylaceto- acetates, small quantities of bye-products containing easily volatile acids which decolorise potassium permanganate are obtained ; these probably result from the decomposition of ketones formed by the action of hydrogen bromide. I n the case of ethylic dibromethyl- acetoacetate, propylideneacetic and butyric acids were identified. These syrupy acid liquids, when distilled, .yield two fractions of which the one insoluble in water contains ethylic mesaconate or homologous compounds, whilst the fraction soluble in water, when distilled with steam, yields acids which are not easily volatile and are not hy droxy-acids.By the action of an aqueous solution of potassium carbonate on e thylic dibromacetosuccinate, an acid, which is probably aconitic acid, is practically the only product, whilst by the action of an alcoholic solirtion of potassium hydroxide, the following a t least are formed :ORGANIC CHEMISTRY. 703 fumaric acid, a dimorphous, crystalline acid which melts at 185-190', aconitic acid, and a syrupy acid.

Clzem. sbc., 23, 430). -A yield of 35-40 per cent. of dimethylmesaconic acid (Demarqay's oxyisohexinic acid) is obtained by decomposing ethylic dibromiso- propylacetoacetate with sufficient alcoholic potash to render the mass permanently alkaline. The acid is purified by converting it into the diethylic salt which boils a t 239-240°, and is easily hydrolysed by alkalis, but only partially by a 50 per cent. solution of sulphuric acid.The acid melts a t 186'; the calcium salt, C7.H804Ca+2H20, crys- tallises from water in small prisms, and the silver salt, C7H,0,Ag2, in needles. Dimethylcitraconic anhydride, prepared by heating dimethyl- mesaconic acid with acetic chloride (2 mols.) a t l l O o , boils at 138' under 61 mm. pressure, melts at 5-25', has a sp. gr. 1-1425 a t Oo/Oo, and dissolves easily in water, forming a solution which decomposes car- bonates and, when evaporated, yields the original anhydride. Calcium dimethylcitraconate, C7H804Ca + H,O, crystallises from water in plates, and the barium salt, C7Hs0,Ba+ l&H20, in small plates ; the silver salt forms a powder and is very sparingly soluble in water. Dimethylitaconic acid, obtained by heating dimethylcitraconic anhydride with 2-3 times its volume of water a t 140", crystallises from water in long prisms and from alcohol in thin, pointed plates, and melts a t 154-156'.Teraconic acid, which must be identical with tbis acid, melts a t 161-163'; when heated, however, at the rate of 4" per minute, it melts at 154-156". Both acids, when heated with a 50 per cent. solution of sulphuric acid, yield terebic acid melting at 174-175', and both form anhydrous barium salts. When dimethylcitraconic anhydride or dimethylitaconic acid is heated with water at 190°, carbonic anhydride is liberated and isocaprolactone, The lactone is a neutral oil, boils at 205-206' under 753 mm. pressure, and, when warmed with baryta water, forms an amorphous barium salt which, with silver nitrate, yields silver hydroxyisocaproate. Terebic acid, when distilled with a 50 per cent.solution of sulphuric acid, forms capro- lactone, hence the formation of the latter from dimethylitaconic acid might easily depend on its conversion into terebic acid, but no trace of terebic acid was found in the acid mother liquor.

By FERDINAND HENRICH (Monatsh., 1899, 20, 539--569).-The hydrogen of the methylene group of ethylic glutaconate, COOEt.CH:CH* CH,*COOEt, is displaceable by alkyl radicles, owing to the influence of the adjacent *CO* and *CH :CH* groups, and in this respect the compound resembles resorcinol, the diketonic formula for which also contains the *CH:CH*CH,*CO* group (Herzig and Zeisel, Abstr., 1890, 1404) ; the substitution, how- ever, takes place much more readily in the glutaconate, both hydrogen atoms being displaced, Ethylic glutaconate has a sp. gr. 1,0499 a t 20'/4'; the index of refraction for sodium light is n, 1.4474 ; the molecular refraction is 47.27, using the formula of Lorenz and Lorentz, the calculated value being 46-87 ; the molecular weight, determined from the freezing point of a solution in benzene, is normal. It is hydrolysed by boiling with caustic soda, or by warming with sodium ethoxide in alcoholic solu- tion ; the sodium derivative, COOEt*CH: CH* CHNa-COOEt, however, is precipitated as a yellow salt when dry ether is added to a freshly- prepared solution of the substance in alcoholic sodium ethoxide. It is readily oxidised by potassium permanganate, and seems to give no characteristic coloration with alcoholic or ethereal ferric chloride, although on one occasion a very pure specimen, after solution in alcoholic sodium ethoxide and precipitation with dilute sulphuric acid, gave an intense red-violet coloration. Methylic iodide acts very vigorously on a solution of ethylic glutaconate in alcoholic sodium ethoxide ; the monomethyl derivative was not isolated, but by hydrolysis of the product a mixture of acids was obtained, of which a fraction melting a t 118-130' seemed to consist chiefly of monome t h ylglu t aconic acid.Dimeth ylglutaconic mid sinters a t 123Oand melts at 129-130", although it only becomes trans- parent at 132-133'; i t dissolves readily in cold ether, alcohol, or acetic acid, less readily in benzene, toluene, chloroform, or light petroleum, and crystallises from water in beautiful, snow-white forms. It is not acted on by nitrous acid, but is oxidised by potassium per- manganate, yielding dimethylmalonic acid. An amorphous sub- stance, insoluble in toluene, was also produced in the preparation of dimethylglutaconic acid ; this melted at 171-1 7Z0, with decomposition, contained C=48*55, H=5*26 per cent., and mas not acted on by potassium permanganate.EthyZic isonits.osogZutaconate, COOEt*CH:CH*C(NOH)*COOEt, pre- pared by the action of nitrous acid on ethylic sodioglutaconate, melts at 81--83', crystallises from light petroleum in white needles, dissolves readily in cold benzene, chloroform, or acetone, and moderately in alcohol or acetic acid.

The inonethylic salt c r y s t a k e s from dilute alcohol in yellow needles, melts and decomposes a t 152-153", dissolves readily in ether, chloroform, or alcohol, less readily in acetic acid, and only slightly in benzene or light petroleum ; it dissolves in sulphuric acid with a reddish-yellow coloration, and gives a transient blue coloration with potassium dichromate, ferric chloride, or sodium nitrite. Ethylic glutaconate condenses with benzaldehyde and acetaldehyde, but definite products were not isolated. Direct Conversion of Acetamide into Ethylamine by Reduc- tion.

Phccrm., 1899, 237, 2SS--299). - By heating together chloracetic chloride, CH,Cl*COCl, and a urethane, NH,* CO*OK. [R = Et, iso-Bu, Ay], and crystallising the product from alcohol, a chloracetyluret hane, COOR*NH* CO*CH,CI, is obtained. When this is heated with a sulpliinate, R'*SO,Na [R' = Ph, paratolyl], in alcoholic solution, a sulphonacetylurethane, COOR*NH*CO*CH,*SO,*R, is formed.This is decomposed when heated with aqueous caustic soda into carbonic anhydride, the alcohol R-OH, ammonia, and the sulphonacetic acid, SO,R'*CH,*COOH ; no doubt the first three substances result from the further action of the alkali on the urethane, COOR*NH,, first eliminated. With alcoholic caustic potash in the cold, the products are the sulphonacetic acid and the urethane, but, on boiling, these undergo further decomposition, in this case into the sulphone R'*SO,*CH, and carbonic anhydride, and into carbonic anhydride, the alcohol R-OH, and ammonia respectively. The compounds prepared, and their melting points, are as follows : C~~lorucetyletl~yluret~~cc~e, 129' ; phenylsu~~onucetylet~yZus.ethane, 69' ; parutoZyZsulphon~cetylet7Lyl- urethane, 103' ; chlorcccetyliso6ut~luretilane, 72' ; phenyZsuZphonucet~Z- isobutylurethccne, 81' ; paratoZylsulphoncccet?/ lisobutylwetl~ane, S9' ; chlorcccetylumyluretllane, 68' ; pl~enylsulpl~onacet~lccmy lurethane, 73.5' ; paratolylsulphoncccet?/lnm?/Zuret?~ane, 83". By heating chloracetic chloride with LZ cnrbnmide, for example, methylcarbamide, NHMe-CO *NH,, a chloracetylcarbamide, N HMe0CO.N H- CO*CH,Cl, is obtained, This reactswith sulphinates as the chloracetyluretbanes do, the two following papers.c.

Action of Potassium Hydrosulphide and Thiocyanate on Chloracetylurethanes and Chloracetocarbamides. By G. FRERICHS (Arch. Phcwm., 1899, 23'7, 300-331).-When a chloracetyl- urethane, COOR*NH*CO*CH,Cl [R = Et, iso-Bu, Ay], is dissolved in warm alcohol and alcoholic potassium hydrosulphide is added gradually until excess is present, potassium chloride is deposited, hydrogen sulphide is evolved, and on pouring the mixture into water a thio-di- gIycolylurethane, (COOR*NH*CO*CH,),S, separates ; it was not found possible to obtain compounds of the type COOR*NH*UO*CH,*SH.IThiodigZycoZ~Z-dietr~yZ-, -di-isobutyl-, and -diamgZ-urethanes melt a t 187') 127O, and 137.5" respectively. Potassium hydrosulphide reacts in a similar manner with chloraceto- carbamides, for example, with NHMe*CO-NH*CO*CH,Cl, yielding thiodiglycolylcar bamides, (NHMe* CO *NH* COO CH,),S. Thiodiglycolyl- car6amide and -dimethylcarbamide are amorphous and decompose with- out melting when heated. When chloracetglethylurethane is heated for a few minutes on the water-bath with potassium thiocyanate in alcoholic solution, and cold water is added gradually to the filtered solution, thiocarbimidoacetyl- ethylurethane, COOEt*NH*UO*CH,*NCS, separates ; this melts at 86' and dissolves in hot aqueous caustic soda, yielding a red solution which evolves hydrogen sulphide when acidified.When boiled for a n hour with water or dilute alcohol, it is converted into the isomeric thiocyanacetylethylurethane, COOEt*NH*CO*CH,*SCN ; this melts a t 174") and dissolves in hot aqueous caustic soda with evolution of ammonia and formation of thioglycollic acid. Tl~iocurbimido- and tAio- cyn*n-acet~lamylurethanes are obtained by similar methods and exhibit similar reactions; they melt at 5 8 O and 147' respectively.When chloracetocarbamide is boiled with potassium thiocyanate in alcoholic solution, three products are obtained in addition to potassium chloride. One of these compounds, thiocyanacetocarbamide, NH,*CO*NH*CO*CH,*SCN, is insoliible in alcohol and decomposes without melting when heated. Of the two others, the less soluble in alcohol is thiohydantoin, NH*CO or NH:C<,-h,-, and the more soluble ethylic allophanate, NH,*CO*NH*COOEtr Probably thiocartimidoaceto- carbamide, NH,*UO*NH.CO*CH;NCS, is the first product, but is converted to some extent into the isomeric thiocyanacetocarbamide, whilst to a still larger extent it decomposes into thiohydantoin andORGANIC CHEMISTRY. 197 cyanic acid, the latter of which at once reacts with ethylic alcohol to form e t h y lic allophanat e.When c hlorace t ocar bamide and potassium thiocysnate are heated together in aqueous solution, thiohydantoin is formed as before, and carbonic anhydride evolved, but apparently no thiocyanacetocarbarnide is produced ; no doubt the carbonic anhydride results from the action of water on the nascent cyanic acid. When chloracetomethylcarbamide, NHMe*CO*NH* CO* CH,Cl, is heated with potassium thiocyanate in alcoholic solution, a smell of methylcarbimide is observed, and thiohydantoin, together with crystal- line thiocyanacetornethylca~bamide, NHMe*CO*NH*CO*CH,*SCN, can be isolated from the product ; in aqueous solution the same result is obtained (it is noteworthy that methylcarbimide and thiohydantoin are formed, not carbimide and methylthiohydantoin).When c?~loracety~~e~~ylcarbam~de, NHPh*CO*NH*CO CH,C1 (which is prepared from chloracetic chloride and phenylcarbamide and melts at 160") is boiled with potassium thiocyanate in aqueous solution, carbonic anhydride is evolved and diphenylcarbamide, thiohydantoin, and pulverulent thiocyanacet y IpJben y I cccrbamide, NHPh*CO*NH* CO*CH2*SC1N, are also formed ; doubtless the first two result from the decomposition of '' nascent " phenylcarbimide. I n alcoholic solution, thiocyanacetyl- phenylcarbsmide, thiohydantoin and phenylurethane are formed, the last doubtless as R result of the action of the alcohol on nascent phenylcarbimide ; some diphenylcarbamide is obtained in this case also, due probably to the presence of water in the alcohol. C. F. B. Molecular Rearrangement of Alkylic "Thioncarbamates. By HENRY L.WHEELER and BAYARD BA~~NES (Amer. Chem. J., 1899, 22, 141--151).-When methylic thioncarbamate, NH2* CS-OMe, is dis- solved in methylic iodide (1 mol.), the solution becomes warm, and finally solidifies to a mass of crystals of methylic thiolcarbamate, NH,*CO*SMe ; this crystallises from water and melts at 107-lOS", not a t 95-98', as stated by Blankenhorn (Abstr., 1878, ii, 215), and is also formed by the action of rnethylic iodide on ethylic thioncarb- amate. This is explained by assuming that in both reactions an inter- mediate additive compound is formed; in the case of ethylic thion- carbamate, NH,. CS-OEt, this would have either the structure NH,. C( OEt):SMeI, assuming sulphur to be quadrivalent, or NH,*C(OEt)I*SMe, assuming it to be bivalent, and, by the loss of ethylic iodide, would give rise to methylic thiolcarbamate, N H,.CO*SMe. When ethylic thioncarbamate is left in contact with ethylic iodide, it yields ethylic thiolcarbamate (" carbonylsulphethylamine," Conrad and Salomon, Abstr., 1875, 753), which melts a t 107-108". Isoamylic thioncarbamate, in contact with isopropylic iodide, gives rise to isopopylic thiolcarbamute, NH,* CO*SPr@, which crystallises from water in colourless, rectangular plates, and melts at about 125O. * The authors adopt the Geneva nomenclature, thhion being used to denote cotn- pounds containing tho group 'CS*OR, and thiol those containing the group *CO*SR.798 ABSTRACTS OF CREMICAL PAPERS. Isobutylic thioncarbamate, NH,* CS*O*C,H,, prepared by the action of alcoholic ammonia on isoamylic ethyldithiocarbonate, SEt*CS*O* C5HII, crystallises from ether or water in white plates and melts at 51-53', not at 36" (Mylius, Ber., 1872, 5, 976), or 10" (Blankenhorn, Zoc.cit.): with dilute alcoholic silver nitrate, it produces a white precipitate which turns black ; with mercuric chloride, a permanently white pre- cipitate; with copper sulphate, a white precipitate which becomes black on warming, and with platinic chloride, a yellow precipitate which, when warmed, decomposes. IsobutyEic thiotcadmmate, NH,*CO*S* C,H,, prepared by heating i t with isobutglic iodide a t 120" for several hours, crystallises from water in thin, snow-white plates and melts at 102-103°; with both silver nitrate and mercuric chloride, it forms a white precipitate which does not blacken, but with copper sulphate and platinic chloride, no precipitate is produced.Isoamylic thioncarbamate (Johnson, this Journal, 1853, 5, 142), when heated with isoamylic iodide, yields the corresponding thiolcarb- amate, NH2*CO*S*C,H,,, melting a t 112--113", not at 107" (Schone, Abstr., 1886, 331). When ethylenic bromide is heated with ethylic thioncarbamate for 3 hours at loo", the ethylene derivative, WH2*CO*S*CH2*CH,.S*C0.NH,, of thiolcarbamic acid is obtained as a crystalline powder, together with small quantities of ethylic thiolcarbamate ; the compound NH,* CO*S*CH,* CH,Br is not formed. I n the light of these results, the fact observed by Debus (Anncden, 1849, 72, IS), that ethylic thioncarbamate, when heated, gives rise to ethyl mercaptan and cyanuric acid, is explained ; it is probable that, in the first instance, the isomeric thiolcarbamate is formed by molecular rearrangement.The authors discuss the structure of the ammonium thiocarbamate, formed by the action of ammonia on carbon oxy- sulphide, and point out that the argument for Fleischer's formula, NH,-CO-SNH, (Bey., 1876, 9, 991), based on the fact that ethylic thiolcarbamate is formed when the compound is heated with ethylic bromide a t loo", does not preclude the thion structure; moreover, the ease with which the salt is desulphurated points to its being NH,* CS*ONH,, for the analogous compound, NH,*CS*OEt, is readily desulphurated by silver nitrate, whilst the compound NH,. CO*S*C,H7 yields a stable silver salt.W. A, D.

The forma- tion of butylbenzoic acids is opposed to the rule that the longer side chain is oxidised to carboxyl; this oxidation of the longer chain, however, is really due, not to its length, but to its containing CH,- or CH-groups attached directly to the benzene ring, such groups being more easily oxidised than methyl groups.I n this case, however, the longer side chain has no such groups and the methyl is therefore attacked. E. W. W. Phenylic Chlorocarbonates. By ETIENNE BARRAL and ALBERT MOREL (BUZZ. SOC. Chim., 1899, [iii], 21, '727-728. Compare this vol., i, 747).--PhennyZic chlorocarbonate, COCl*OPh, is a colourless liquid which rapidly becomes red ; it boils without decomposition at 95' under 20 mm. and a t 97-98' under 25 mm. pressure, but under the ordinary pressure it boils a t 187', decomposing into phosgene and diphenylic carbonate.OrthotoZylic cldorocarbonate, COCl*O*C6H4il!Ie, is a colourless liquid which rapidly becomes violet ; it boils at 119' under 35 mm. at 114' under 25 mm, pressure, and when boiled under the ordinary pressure decomposes into phosgene and di-ortho- tolylic carbonate. Guaiacylic chlorocarbonccte, COC1*O*C,H4*0Me, boils at 112' under 25 mm. pressure, but decomposes when boiled under the ordinary pressure, yielding digixaiacylic carbonate. Phymnylic chlorocarbonate, COC1*O*C,H3MePr, boils a t 122-124' under 25 mu. pressure, and when boiled under ordinary conditions yields dithymylic carbonate. W. A. D. By EMANUEL MERCK (Chem.

H. R. LE S. Condensation of Succinic Anhydride and Pyrogallol. By QEORG VON GEORGIEVICS (Monutsh., 1899,20, 450--461).-The author has isolated two dyes from the numerous substances which are formed by the condensation of succinic anhydride and pyrogallol. Pyrogallolsuccineir, CI6Hl4O8, is obtained when a mixture of equal parts of succinic anhydride and zinc chloride is heated for several hours a t 170" with an equal weight of pyrogallol. It forms a reddish- brown powder, is practically insoluble in the ordinary solvents, and decomposes at 180". When boiled with alcoholic hydrochloric acid, it yields a monohydrochloride crys t allising in brownis h-yellow, micro- scopic plates, The sulphate crystallises from concentrated sulphuric acid in dark- blue crystals.The colouring properties of pyrogallol- succinein are very similar to those of gallein. Digallacyl, C6H2(OH)3* CO*CH2* CH,* CO*C,H,(OH),, is prepared by heating a fused mixture of 1 part of succinic anhydride and 2 parts of pyrogallol for 10 minutes at 150° with one-third its weight of zinc chloride, It crystallises in tufts of slender, glistening, colourless needles, and darkens, without fusing, at about 2?0°. It dissolves in alcohol or acetic acid, but is almost insoluble in other ordinary sol- vents; strong caustic soda dissolves it, forming a yellow solution, whilst in cold concentrated sulphuric acid it forms a yellow solution which, when warmed, suddenly becomes a deep-violet.As a dye, i t is very similar to gallacetophenone. Hexacetyldigullucyl forms microscopic prisms, melts a t 170--171°, and is very soluble in acetic acid, but almost insoluble in alcohol. Digullacylosaxone crystallises from alcohol with 1 mol. of the solvent in tufts of yellowish needles, darkens in colour about 190", and decomposes suddenly a t 206-20'7". Isomeric Change in [the Formation of] Homologues of Phloroglucinol. By R. REISCH (Monatsh,, 1899, 20, 488-503).- Various homologues of phloroglucinol, in methyl alcoholic solution, were treated successively with sodium methoxide and methylic iodide. Trimethylphloroglucinol gave a quantitative yield of hexamethyl- phloroglucinol : dimethylphloroglucinol a mixture of hexamethyl- and tetramethyl-phloroglucinol : monomethylphloroglucinol, a mixture of hexamethyl-, pentamethyl-, and tetramethyl-phloroglucinol : products exclusively of the ketonic type.Trimethylphloroglucinol monometh ylic ether yielded pentamethylphloroglucinol monomethylic ether ; dimethyl- phloroglucinol gave a product soluble in alkali, probably tetramethyl- phloroglucinol, together with tetra- and probably penta-methylphloro- glucinol monomethylic ether ; monomethylphloroglucinol monomethylic ether gave a mixture of tetra- and penta-methylphloroglucinol mono- methylic ethers: no increase in the number of methoxyl groups occurs, ketonic compounds being formed as the result of methylation.

Compare Abstr., 1898, i, 40, and this vol., i, 32).-The author repre- sents the constitution of filicic acid by one of the formuls C M e ~ < ~ [ ~ $ i ~ ~ > c o ~ and CMe2<C0-CH '(OH): cH>G*OH, which illus- trate the close relation between this compound and phloroglucinol ; tetrabromofilicic acid has the constitution expressed by the formula Filicic acid Gystallises from.alcohol in small, colourless cubes, and melts at 213-215", when it becomes brown; the aqueous solution develops a red coloration with ferric chloride, and reduces potassium permanganate and an ammoniacal silver solution. On adding a colourless specimen of aniline to the alcoholic solution, a beautiful, reddish-violet coloration is slowly developed ; when the crystalline acid is heated with aniline and acetic anhydride or glacial acetic acid, an emerald green coloration is gradually produced. The methyl ether, C,H,O,*OMe, prepared by saturating a hot solution of filicic acid in methylic alcohol with hydrogen chloride, crystallises from ethylic acetate in colourless, lustrous prisms, and melts at 208"; it dissolves with difficulty in boiling water, and develops a violet red coloration with ferric chloride.The ethyl ether crystallises from alcohol in lustrous prisms, and melts a t 215'; the diethyl ether, C,H,O(OEt),, prepared by heating it with ethylic iodide and alcoholic potash, crystallises from light petroleum in quadratic plates or long prisms melting at 103-105°, and is indifferent towards ferric chloride. The diacetyl derivative, C,H,O(OAc),, crystallises from alcohol in large, six- sided plates and melts at E2--85"; it is indifferent towards ferric chloride. When the potassium salt of filicic acid is oxidised with potassium permanganate, 35 per cent. of dimethylmalonic acid is produced.The dichloride of filicic acid, C,H,CI,O, prepared by the action of phosphorus pentachloride, crystallises from light petroleum in six-sided and rhombic plates, melting at 79-80'. The cornpound, C,H,O,*O*POCl,, arising from the action of phosphorus oxychloride, occurs as a bye-product ; it crystallises from chloroform in small plates, and decomposes at 15S-16Oo. Dibromojilice'c m i d , CsHsEr203, prepared by suspending filicic acid in absolute alcohol and slowly adding bromine, crystallises from carbon bisulphide in large, colourless prisms, and melts at 147-14SO; exposure to air causes the substance to become yellow, and change gradually into bromofilicic acid, which is also produced when theORGANIC CHEMISTRY. 805 dibromo-compound is digested with glacial acetic acid or with boiling water.Tribomo4licic acid, CsH7Br303, obtained when bromine acts on filicic acid in the dry state or suspended in glacial acetic acid, crystallises from carbon bisulphide in lustrous, rhombic plates and prisms, becoming yellow a t 120" and melting at 132". Bromofilicic mid, CsH,BrO, or C8H,Br0,, produced when either of the foregoing bromo-compounds is digested with boiling water, dissolves with difficulty in common solvents excepting acetone ; it crystallises from glacial acetic acid in small, orange-red cubes and quadratic plates, and decomposes without fusion above 250". Filicic acid is regenerated when the bromo-derivative is reduced with sodium amalgam, and oxidation with potassium permanganate gives rise to dimethylmalonic acid.Tetmb~omoj licic c6c id (d imet ft,y Ztetrubyonzocy c lohexune-1 : 3 : 5-ti*ione), C8H6Br4O3, formed when tribromofilicic acid is dissolved in excess of bromine, is best prepared by slowly adding bromine to a neutral or feebly alkaline solution of filicic acid in aqueous potash ; it crystallises from alcohol in lustrous prisms and six-sided plates, melting a t 139". The alcoholic solution is indifferent towards ferric chloride, but liberates iodine from potassium iodide, Caustic alkalis act readily on tetrabromofilicic acid, converting it in to hexabromodimethylacetyl- acetone, and the compound, C7H,Br03, which crystallises from water in colourless, lustrous prisms containing 1+H20, melts a t 1 '79-lSOo when anhydrous, develops an intense red coloration with ferric chloride and yields a crystalline barium salt.Hexubromodimethylcccetyhcetone, CMe,(CO*CBr,),, is prepared by adding finely powdered filicic acid to a large excess of bromine, and, after an interval, adding 15 per cent, caustic soda until the liquid is alkaline; it separates from glacial acetic acid in large, lustrous crystals, and melts at 149-150". The alcoholic solution is indifferent towards ferric chloride, and liberates iodine from potassium iodide. ~etrubromodimethykucetylucetone, CTH,Br,02, obtained by adding bromine to dimethylacetylacetone until action ceases and allowing the excess of halogen to evaporate, crystallises from light petroleum in large, lustrous prisms and melts a t 7 8 O ; further treatment with bromine leaves the substance unchanged, but if a solution in the halogen is treated with 15 per cent, caustic soda, hexabromodimethyl- acetylacetone is produced.Z'etrachlorofilicic acid, C,H,CI,O,, prepared by saturating with chlorine a solution of filicic acid in chloroform, crystallises ic snow- white prisms several centimetres in length; it melts at 83-84'.

When paranitrobenzylic chloride is heated with diphenylamine until action takes place, diphenylamine-blue is obtained j the nature of the bye-product has not been yet determined. Action of Aromatic Amines on Chloracetylurethanes and Chloracetocarbamides. By G.FRERICHS and HEINRICH BECKURTS (Arch.

H. R. LE S. Compounds of Phenylhydrazine with Cuprous Salts. By JOSEPH MOITESSIER (Bull. Xoc. Chim., 1899, [ iii], 21, 666-668).-The compounds which phenylhydrazine forms with cuprous chloride, bromide, and iodide are nearly insoluble in cold water, dissolve in sodium thiosulphate solution, and are decomposed by alcohol and ether, which dissolve out the phenylhydrazine. They gradually alter on expo- sure to air, especially when moist, and are rapidly decomposed at higher temperatures. PhenyAydrazine cuprochloride, 2Cu2C1,,5N,H,Ph, obtained by adding excess of phenylhydrazine to a cold solution of cuprous chloride in 10 per cent, aqueous sodium chloride, crystallises in white needles ; it begins to decompose at 65', then becomes brown, and is rapidly decomposed at 110'.Phenylhydmxine cupobromide, 2Cu,Br2, 7N2H3Ph, prepared by adding phenylhydrazine to cuprous bromide dissolved in aqueous potassium bromide, crystallises in slender, white needles which begin to decompose at 70° and undergo rapid decomposition a t 14 0'.

Similar reactions are found to occur when precipitated copper is added to a mixture of cupric salts with pyridine. N. L. Action of Phenylhydrazine on Alkylic Bromides, Chlorides, and Iodides. By JULES ALLAIN LE GANU (Compt. ?*end., 129,105-106. Compare Genvresse and Bourcet, this vol., i, p. 501).-To a well- cooled ethereal solution of phenylhydrazine (1 mol.) was added gradually and with constant stirring half a mol.of ethylic bromide free from hydrogen bromide; a t the end of 24 hours, there was a deposit in slender needles of a cowpowad, which, on analysis, proved to be a combination of two mols. of phenylhydrazine with one of hydrogen bromide; it melts and decomposes at 195', and on prolonged heating at 100' loses one mol. of phenylhydrazine ; it is slightly soluble in ether, soluble in alcohol, and very soluble in water ; its aqueous solu- tion is acid, and with silver nitrate gives a white precipitate which blackens rapidly. If alcohol is employed as solvent in place of ether, phenylhydrazine hydrobromide is the product. The action of ethylic chloride on phenylhydrazine is similar to that of ethylic bromide, the analogous compounds being formed both in ethereal and alcoholic solutions ; the hydrochloride containing 2 mols.of phenylhydrazine melts a t about 225' and is less stable than the corresponding hydrobromide. The compounds (PhN2H3),,C3H7T and (PhN,H,),,C,H,I are formed by the action of propylic iodide and normal butylic iodide respectively on phenylhydrazine ; the former crystallises from alcohol in brilliant needles, is soluble in water, but only slightly so in ether, and melts at 122'; the latter has similar properties, and melts at 126'. H. R. LE 8. Action of Phenylhydrazine on Chloracetocarbamides and Chloracetylurethane. By G. FRERICHS and HEINRICH BECKURTS (Arch.

The substances soluble in dilute hydrochloric acid were unsymmetrical phenylh ydrazidacetocarbamides, i NHRl* CO *NH* CO*CH,*NPh*NH,. PhenyZr7Lydruxiduceto-curbamide, -rnethyZcarbamide, -phenylcarbamide, and -4-ethoxypr7Lenylcarbamide melt at 188O, 185O, lSO', and l69', and their benxylidene derivatives at 219', 238O, 177", and 179" respectively.The first of these yields unsymmetrical phenylhydrszidncetic acid (Harries, Abstr., 1895, i, 460), with evolution of ammonia, when it is boiled with aqueous caustic soda.ORGANIC CHEMISTRY. 809 The substances insoluble in dilute hydrochloric acid, in the case of the phenylic and 4-ethoxyphenylic compounds, were oxidation products, NHRl* CO *NH* CO*CH:N*NHPh,of the symmetrical phenylhydrazido- derivatives, which doubtless were first formed ; plhenylhydvazine- glyoxylyl-phenylcarbamide and -4-ethoxyphenylca~barnicle melt at 19 7'" and 151" respectively. I n the case of the. methylic compound, the product was unfortunately lost. From chloracetocarbamide and -urethane, an identical product was obtained: probably a sym- metrical phenylhydrazine, was formed as before, and then the central CO-group condensed with a second mol.of pbenylhydrazine, when from the resulting compound, by elimination of ammonia in the one case and alcohol in the other, a compound, AOeNH >C*CH:N*NHPh, was formed. This is yellowish, melts at 275", and has a feebly acid character ; a mono-silver derivative was prepared. I n the case of carbamide itself and of methylcarbamide the unsym- metrical derivatives form the main product ; in the case of phenyl- carbamide and 4-ethoxyphenylcarbamide about equal amounts of both derivatives are formed. This is in harmony with the fact, already recognised, that chloracetyl derivatives of radicles having an acid nature yield symmetrical derivatives of phenylhydrazine, whilst those of radicles having a basic nature yield unsymmetrical derivatives. It has been shown in a previous paper (p.806) that aromatic glycocinyl derivatives of carbamide readily yield P-hydantoins by elimination of ammonia. I n a similar fashion, when unsymmetrical phenylhydrazidaceto-carbamide or -methylcarbamide is heated a t about 200°, ammonia or methylamine is evolved and l-phenyldiketotetra- hydro-a-triaxine, CO<NH-Co>CH2, is formed ; this melts at 229' and has an acid character. NPh-N NH*NPh C. F. B. Acetylleucomethylene-Blue. By GEORG GOWN (Arch.

Acetylleucoethylene-blue, NAC<~~~~(~&'~)>S, C H (NFt ) was prepared in the same way as the analogous rnethylene compound, and has similar pro- perties; it melts at 179-180". 6 3 G'.F. C,810 ABSTRACTS OF CHEMICAL PAPERS. Symmetrical Dinitroditolylcarbamides. By HENRI VITTENET (BUZZ. SOC. Cl~irn., 1899, [iii], 21, 659--665).-These compounds have been prepared by methods analogous to those employed in the pFe- paration of the dinitrodiphenylcarbamides (this vol., i, 692), namely, by heating the various isomeric nitrotoluidines (2 mols.) with carbonyl chloride or with phenylic carbonate. Dinitroditolylcarbamide, CO(NH*CGH,Me*NO,), [NH : Me : NO, = 2 : 1 : 51, from 5-nitrorthotoluidine, crystallises from boiling anhydrous acetic acid in small, white needles melting and subliming a t 305-310°, and is insoluble in water, ether, benzene, or chloroform, slightly soluble in alcohol, more so in acetic acid. It is reduced by tin and hydrochloric acid to diarnidodiiolylcarbamide, CO(NH*C,H,Me*NH?),, which crystallises from boiling 95 per cent.alcohol in small, white needles melting at 264-265". Dinitroditolylcarbamicle, [NH : Me :NO, 1 4 : 1 : 31, from 3-nitropara- toluidine, crystallises from boiling acetic acid in yellow needles melting and subliming a t 244-245', and is soluble in alcohol or benzene, but insoluble in water. It is not reduced by stannous chloride, but when heated with zinc dust and acetic acid is converted into driarnidodi- tolylcarbamide, which crystallises in slender, white needles and is insoluble in water or benzene, but slightly soluble in boiling alcohol ; when heated, it sublimes without melting. Dinitroditolylcai*bamide, [NH :Me :NO, = 2 : 1 : 41, from 4-nitrortho- toluidine, crystallises from boiling acetic acid in small, white needles melting and subliming at 300-305°, and is insoluble in water, benzene, chloroform, or ether, slightly soluble in alcohol, more so in boiling acetic acid.On reduction with tin and hydrochloric acid, it yields diamidoditolylcccrbamide, which crystallises in white, microscopic needles, decomposes when heated, and is insoluble in water, benzene, or ether, but dissolves very slightly in boiling alcohol. Dinitroditol~lcarbamide, [NH :Me :NO, = 4 : 1 : 2 J, from 2-nitropara- toluidine, is fairly soluble in boiling alcohol, acetic acid, or ethylic acetate, and crystallises either in white needles or i n yellow prisms, in this respect resembling dimetanitrodiphenylcarbamide (Zoc. cit.). The two modifications melt a t the same temperature, 251-252", and when treated with tin and hydrochloric acid yield products having the characteristics of tolylenediamines mixed with a small quantity of monumidoditolylcarbamide, C,H,Me*NH* CO*NH*C,H,Me-NEE, ; when zinc dust and acetic acid are used, tolylenediamines alone are obtained. 3-Nitroparatoluidino, in which the NO, and NH, groups occupy the ortho-position with regard t o each other, resembles orthonitr- aniline in entering into reaction with carbonyl chloride, but not with phenylic carbonate.N.

HccZZe, 21, 233--250).-The proximity of the carbonyl group renders the hydrogen atoms attached to a-carbon atoms more easily replaceable, and two carbonyl or negative groups (*CO*CH,*CO* or *CO*CH,*CN) may even cause the hydrogen atoms t o he capable of ionisation (compare von Schilling and Vorlander, AnPnuZen, 1899, 308, 184). The prox- imity of a carbonyl group to a double Iinking(*CH:CH*CO*), confers the additive properties of ethylic sodiomalonate, &c., on up-unsaturated alkylic salts and ketones.Phenylethylene and the following derivatives, C,H,Ph, C,H,*NO,, C,H,*C,NH,, C,H,*CH:N*NHPh, C,H,-CMe:N*NHPh, are incapable of forming additive compounds with compounds of the type of NaHC(COOR),. The following deriva- tives of cinnamic acid combine with alkylic salts of sodiomalonic acid, C,H,* COOEt, (6), C,H7* COMe, C,H,*CO*NH,, C,H7*CO*NHMe (43), C,H,*CO *NHEt (44), C,H,* CO *NHPb, C,H,* CO *NMe, (29), C,H,,*CO*NEt, (46), C,H,*CO*C,NH1, (as), C,H,*CO*NPh, (32), the numbers in brackets referring t o the percentages of each compound which remain uncombined after the reaction has gone on for 6 hours. There is apparently no fundamental difference between the alkylic salts and the amides.The more or less positive character of the amine also has litble influence, and tertiary and secondary amines behave in a like manner.

Halle, 21, 251--270).-The unsaturated compounds were treated with ethylic sodiomalonate by dissolving them in alcohol together with sodium, adding ethylic malonate, and boiling the mixture for 6 hours. I. Unsaturated compounds not containing carbonyl. By the action of ethylic sodiomalonate on styrene, metastyrene is formed. Phenylnitroethylene is partly polymerised, forming a slightly soluble, white, amorphous compound, (C,H7*N0,),, which melts at 280O.Stilbene, benzylidenequinaldine, cinnamaldehydephenylh ydrazone, and benzylideneacetophenonehydrazone are not attacked. 11. Unsaturated compounds containing carbonyl. Alkylic cinnamates and cinnamamides all combine with ethylic sodiomalonate, forming the compounds (COOEt),CH* CHPh- CH,*COOEt and (COOEt),CH* CHPh* CH,. CO*NH,, which, when hydrolysed with cold sodium hydroxide solution, yield phenylglutarocarboxylic acid and phenylglutaramidocarboxylic acid respectively. The former is easily soluble in water. Phenylglutar- amidocarboxylic acid and most of its derivatives dissolve easily in dilute hydrochloric acid and cannot be separated from the unchanged cinnamic acid, but by heating them with concentrated hydrochloric acid, carbonic anhydride is eliminated and P-phenylglzcturic acid, C,,H,,O,, is formed.An almost quantitative yield of this acid is also obtained by treating ethylic cinnamate with sodium (l-li ats.) ; i t crystallises from water in white, prismatic plates, melts a t 138*, is slightly soluble in benzene, and is only attacked by alkaline solutionsORC4ANIC CHEMISTRY. 813 of potassium permanganate with difficulty.

Heated at 1OSo, it decomposes and becomes black, and when boiled in a reflux apparatus with alcohol, it is split up into mercuric sulphide and mercury diphenyl. It is soluble in cold carbon bisulphide, and the solution deposits first colourless, silky needles and afterwards a yellowish substance which only partially redissolves in carbon bisulphide, and is shown to be mercuriphenyl thiocarbonate, (PhHg),CS,. This compound is insoluble in water or alcohol, slightly soluble in ether or benzene, more so in chloroform, and is completely dissolved by hot fuming hydrochloric acid.At 1OSo, it blackens, mercuric sulphide being formed and carbon bisulphide evolved, and when heated with benzene, it decomposes rapidly with the production of mercuric sulphide and mercury diphenyl.

G. T. M. Dimethyldianthracene, a Polymeride of P-Methylanthracene. By WILLIAM It. ORNDORFF and H. A. MEGRAW (Amer. Chem. J., 1899, 22, 152--157).-When P-methylantliracene, suspended in benzene, is exposed to the action of sunlight, it is rapidly polymerised into dimethyl- diccnti~rcccene, (CI5HJ2, just as anthracene, under similar conditions, gives rise to dianthracene (Orudorff and Cameron, Abstr., 1896, i, 176) ; the product crystallises from toluene in small, probably orthorhombic, crystals and melts a t 228--230°, decomposing partially into P-methyl- anthracene.Its molecular weight was determined by the boiling point method, using toluene and pyridine as solvents. Unlike P-methyl- anthracene, it is non-fluorescent, and does not form a compound with picric acid. It is very sparingly soluble in all the ordinary solvents, but when boiled for a long period with anisoil or metaxylene, becomes partially soluble owing to conversion into P-methylanthracene. W. A. D. Optical Rotation of Pinene Hydrochloride. By JOHN H. LONG (J. Amer. Chem. SOC., 1899, 21, 637--642).-Pinene hydrochloride melts a t 131°, and not at 125" as stated by Pesci (Abstr., 1889, 158) and others. Various values have been given by different authorities for the specific rotatory power of the hydrochloride (compare Berthelot Ann.Chirn. Phys., 1854, [El, 40,5; Flawitzky, Ber., 1882,15,5; Marsh andGardner,Trans., 1891,59,725; Pesci, Zoc. cit. ; Wallach andconrady, Abstr., 1889,1072). The different values-from 0" to + 30"-are due to the fact that the hydrocarbon employed by the different authorities contained varying amounts of cl- and Fpinene. From experiments made by the author, it appears that the .hydrochloride of I-pinene has a higher rotatory power than I-pinene, whereas the hydrochloride from d-pinene has a slightly lower rotatory power than cl-pinene. J. J. S. Crystallographic Relations of Optically Active Substances and their Racemic Compounds [Pinonic Acids]. By ANDREAS FOCK (Zeit.Kryst. Min., 1 S99, 31, 479-4S3).--0ptically active substances may be divided into three groups : (1) those with no racemic compounds, the t mo antipodes crystallising separately from the mixed solution ; for example, aspsragine and cis-wcamphanic acid ; (2) those in which the antipodes unite in constant proportions to form a racemic compound, for example, tartaric acid and tartrates; ( 3 ) those in which the antipodes unite in varying proportions t o form numerous racemic or pseudoraceniic compounds, for example, limonene tetrabromide and brucine valerate. Between groups (1) and (2) there is a connecting link, thus the racemate, (C4H40,NaNH,)2 + 2H20, is formed from the two tartrates above 27", whilst below this temperaturo the two antipodes crystallise separately.A connecting link between groups (2) and (3) is now described. The optically active pinonic acid crystallises in tetrngonzcl pyramids, and the two antipodes have the same form [ a : c = 1 : 1.127571. Circular polarisstion could not be observed in the imperfect crystals, but their solutions show wide variations in the rotatory power ; in the lwo-acid, [@ID reaches 20°, and in the dextro-acid, [a]D may reach 130". 3 2 2820 ABSTRACTS OF CHEMICAL PAPERS. This variation is t o be explained by the capability of the two modi- fications mixing together as isomorphous substances. The racemic compound of the two active pinonic acids forms tabular, monoclinic crystals [a : b : c = 0.6445 : 1 : 0.5585 ; P= 76O 8'1. Solutions of these crystals show rotations up to [ u ] ~ = loo.The two active compounds must therefore, to a certain extent, crgstallise isomorphously with the racemic compound, giving a passage between groups (2) and (3). This would be expected to take place in the pseudo-racemic compounds, the crystalline forms of which differ only slightly from those of the corresponding active substances. Amongst inorganic salts, group (2) is represented by double salts and (3) by isomorphous mixtures, and there are also analogous connecting links between the groups. Arnidocampholenes. By EDMOND E.

Xoc. Chim., 1899, [iii], 21, 322). Attempts were therefore made to obtain this from each, but instead of the amidodihydrocampholene, a base was obtained the boiling point of which was much higher than that of the compound sought. H.

Nataloin, C1,Hl8O7, the more soluble compound, forms pale yellow scales less soluble in methylic alcohol than barbaloin, and insoluble in hot water or ether. Like barbaloin, it possesses a phenolic character, and dissolves in alkaline solutions, -from which it is re- precipitated by carbonic anhydride.It dissolves in ammonia or pyridine, but combines with acids less readily than barbaloin. Acetic chloride forms with it a small quantity of a crystalline acetyl deriva- tive separating in octahedra and in scales, but the principal product is a yellow, amorphous substance very soluble in ether. Tyibenxoyl- nataloh, C1GH1507B~3, obtained by the action of benzoic chloride on nataloin in pyridine solution, forms a yellow, tumid mass very soluble in ether or alcohol, but insoluble in water or dilute solutions of the alkalis; it is devoid of bitter taste. The tetrabenaoyl derivative, Cl6Rl4O7Bz4, obtained by heating the aloin with benzoic chloride in sealed tubes a t looo, separates from alcohol in yellow, amorphous granules.Honzonatuloin, C,,H1,O7, the less soluble constituent of the crude aloin, separates from methylic alcohol in nodular masses of yellow lamells; its acetgl derivative is amorphous. The tri- and tetra- benzoyl derivatives, C,,H,,07Bz, and C,,H,,07Bz, are obtained in brick-red granules. These aloins develop a green coloration with sulphuric acid and manganese dioxide or potassium dichromate, and a violet with a soda solution containing ammonium persnlphate ; the latter colour dyes silk, but cannot be fixed on mordanted cotton. These colour reactions distinguish the aloins of Natal aloes from barbaloin. Brazilin and Hmnatoxylin. By JOSEF KERZIG (Monatsh., 1899, 20, 461-466.

Gossypol, a Constituent of Cotton-seeds. By LEO MARCH- LEWSKI (J. p. Chem., 1899, 60, 84--90).-When the phenolic con- stituents of cotton-seed oil are purified by repeated fractionation from acetic acid solution, a crystalline product is obtained which can be further purified by crystallisation from a mixture of alcohol and dilute acetic acid; this substance, to which the name of gossypol is given, has a composition corresponding fairly well with that required for the formula C,,H,,O,. Gossypol crystallises in glistening, golden scales, melts at 18S0, dissolves readily in alcohol, benzene, chloroform, ether, acetone, or acetic acid, but not in water.Sulphuric acid dissolves it with a beautiful, cherry-red coloration, similar t o that observed with impure cotton-oils. Alkalis give a yellow solution, which soon be- comes violet and then gradually loses its colour; the violet colour is developed immediately when hydrogen peroxide is added to the alkaline solution. Alkaline solutions of gossypol reduce both Fehling’s solution and ammoniacal silver nitrate. An alcoholic solu- G. T. M. R. H.

The oil was yellow and had a faint odour of oil of almonds ; it had a solidification point - 13*5O, sp. gr. 0.922 at 15”, solubility 4-15 parts in 100 of 95 per cent. alcohol, index of refraction 1.47248 for green, 1.47292 for red, viscosity 16.4 at 17” (by Schubler’s method, comparing its velocity of efflux with that of water) ; i t was optically inactive and showed obscure absorption bands in the blue and violet.1 gram neutralised 31.7 milligrams KOH in tho cold (“acid number ”), 181.7 on heating (‘( Koettstorfer’s ” or ‘‘ saponification number”); 5 grams contained volatile acids soluble in water sufficient to neutralise 0508 C.C. N/lO KOH solution ((‘ Reichert- Meissl number ”) ; it contained 95.2 per cent. of fatty acids insoluble inwater (“Hehner’s number”), and united with 113 per cent. of iodine (“ Hubl’s iodine number ”). By hydrolysis of the oil with lead oxide, glycerol was obtained to the extent of 4.1 per cent. A larger quantity of the oil was hydrolysed with caustic soda, and the acids converted into calcium salts, which were then treated with ether, From the calcium salt soluble in ether, a liquid acid was obtained, and purified by conversion into its ethylic salt and fractional distillation of the latter. This acid has a sp.gr. OaS931 and composition OH*C,7H,,*COOH ; its ethylic salt boils a t 223-226O under 7.5 mm. pressure; an anhydrous bcwiurn salt, melt- ing at 79O, and a monacetyl derivative were prepared; a dibromide, C1SN3403Br2, was also prepared, and the acid was found to darken in the air, absorbing oxygen. From the calcium salt insoluble in ether, a mixture of solid acids was obtained from which two were separated by crystallisation from 70 per cent. alcohol ; these were myristic acid, the main product, and a small amount of an acid which melts a t 42”, contains C 75.1 and H 12.1 per cent., and is possibly a n isomeride of pentadecylic acid.C.

It does not give the pyrroline reaction with isatin, nor does it colour cold concentrated sulphuric acid, but gives immediately an intense red coloration to a pine shaving moistened with hydrochloric acid. The salts formed with the alkali and alkaline-earth metals are very soluble in water; the lead salt forms a white precipitate, and the silver salt colourless, very slightly soluble flocks which change rapidly even in the cold, and when suspended in water and heated are instantly reduced ; the mercury salt is deposited as a bulky, colourless precipi- tate which becomes red, slowly in the cold and more rapidly on heating.>C*CH,* COOH, prepared from 1'-methylindole and ethylic diazoacetate, forms colourless prisms melting a t 128-129", and is very soluble in benzene or alcohol, less so in boiling water, and only very slightly in light petroleum.

Action of Iodine on Bilirubin. By ADOLF JOLLES (Monatsh., 1899, 20, 282-306, and J. p ~ . Chem., 1899, [ii], 59, 308-319j.- The author maintains that, contrary to the view taken by Thudichum (Abstr., 1896, i, 516), the action of iodine in very dilute solution on bilirubin is essentially one of oxidation, and not of substitution, the product being biliverdin. When bilirubin dissolved in chloroform is treated with a dilute solution of iodine in alcohol, or, better, with Hubl's solution, the same coloured products are obtained as when nitric acid is used as the oxidising agent.The extent of the oxidation depends on the concen- tration of the solutions, the duration of the action, and tho miscibility of the liquids used as solvents. It is also necessary to operate on small quantities at a time, 20-50 milligrams of bilirubin, dissolved in 50-50 C.C. of chloroform, being oxidised with N/lO alcoholic solution of iodine, or better, with NIlO Hubl's solution. The production of H. R. LE 5.ORGANIC CHEMISTRY. 531 biliverdin is accomplished by using the materials in the proportions indicated by the equation Ci,Hi,N20, + 21 + H20 = Ci6Hi,N,0, + 2H1, the mixture being well shaken and left for some time; the solution of the product is finally washed with very dilute hydrochloric acid until hydriodic acid can no longer be detected in the wash-liquors.Biliverdin, Ci6H,,N20,, is a green, amorphous substance, and resem- bles the compound obtained by Maly’s method (Annalen, 1874, 1’75, 82) in its solubility in various liquids. The solution in alcohol, ren- dered slightly acid with mineral acids, gives with acids a bluish-green, and with alkalis a brownish-green, coloration, which gradually fades. On adding ammoniacal alcoholic zinc chloride to the alcoholic solution, a reddish-brown liquid with a green fluorescence is obtained, and when zinc dust is added to the solution of the substance in sulphuric or alcoholic hydrochloric acid, the colour changes to yellowish-green and finally to yellow. When chlorine water is passed down the side of a vessel containing a solution of the substance i n alcoholic hydro- chloric acid, a blue ring is formed a t t h e bottom of the vessel, the supernatant layer being successively violet, red, and yellow ; on adding more chlorine water, the whole becomes yellow, and finally colourless.Potassium permanganate and hydrogen peroxide produce similar colour phenomena. The spectra given by the author (Abstr., 1894, ii, 466) for bilirubin and biliverdin differ from those of the substances obtained by Maly’s method, inasmuch as they exhibit bands due to the presence of an impurity in the substance purchased as pure from a manufacturing firm. Pure biliverdin in alkaline solution shows no absorption bands, but the acidified solution shows a weak band a t about D, and one more strongly pronounced between E$F and F.If bilirubin, dissolved in chloroform, is left for some days with excess of Hubl’s solution, an amount of the latter equivalent to three atomic proportions of oxygen is used up. The product, for which the author proposes the term bilixanthin, may be isolated by washing the chloroform solution with water acidified with hydrochloric acid, the solvent being subsequently removed by careful evaporation. Bilixan- thin, Ci6Hi!N20fi, does not exhibit any tendency to crystallise, and is possibly identical with ‘( uroxanthin,” a substance obtained by the author from urine. It dissolves in alcohol or chloroform, is soluble for the most part in ether and more so in amylic alcohol, but is in- soluble i n carbon bisulphide; it is insoluble in the common mineral acids, and the presence of these does not influence its solubility in alcohol; it dissolves for th’e most part in solutions of alkalis and alkali carbonates.An alcoholic solution of bilixanthin is not altered on addition of hydrochloric acid and zinc dust, or on treatment with hydrogen sulphide, and it does not exhibit any fluorescence with a n ammoniacal solution of zinc chloride. Bilirubin in urine may be fairly accurately estimated by taking advantage of the fact that it is converted into a green colouring matter by means of a n alcoholic solution of iodine, two atomic proportions of the latter being required. The method consists in extracting the biliary colouring matters with chloroform, shaking the latter with z known quantity of iodine solution for some minutes, and finally832 ABSTRACTS OF CHEMICAL PAPERS.titrating the excess of halogen wifh thiosulphate ; the description of the details, however, is lengthy and unsuitable for abstraction. A. L. Solvent Power of Pepsin. By JEAN EFFRONT (Bull. Xoc. Chiwa., 1899, [iii], 21, 683--691).-The solvent power of pepsin, which should be carefully distinguished from its hydrolytic or peptonising proper- ties, increases with the acidity of the medium until a maximum is reached, after which a decrease is observed. Hydrochloric acid is con- siderably more effective than sulphuric acid, but the amount required to bring about the best results depends on the state of division of the proteid, and on other circumstances. The solvent power of different samples of pepsin may be compared by measuring the time required to render transparent a definite volume of a 4 per cent. emulsion of albu- min; a detailed description of this method is given in the paper.The rate of solution is largely dependent on the temperature, being most rapid at 65' in the case of neutral solutions, whilst in the presence of 0.15, 0.3, and 0.4 per cent. of hydrochloric acid, the most favourable temperatures are 65", 55", and 50" respectively. I n each case, it is found that solution takes place most rapidly at a temperature approaching that at which, under the given conditions of acidity, destruction of the ferment occurs. Peptic solution is retarded by the addition of metallic salts, and the effect of a number of these was examined quantitatively.Sulphates, and particularly ammonium sulphate, are most active in this respect. Caffeine, fatty acids, and alcohols are without influence. N. L. Action of Trypsin on the less Complex Chemical Compounds. By WL. GULEWITSCH (Zeit. physiol. Chem., 1899, 27, 540-556).-1n view of Kossel's work on the action of trypsin on protamine, and in the hope that some light might be shed on the constitution of the proteid molecule, a number of organic compounds such as phenetoil, ethyl- aniline, diphenylcarbamide, acetanilide, orthacetamidobenzoic acid, and salol, were subjected to the action of the tryptic ferment. The results of the experiments were negative, except in the case of para- diacetylamidophenol, which, with powerful solutions of trypsin, gave rise to acetic acid.Nencki and Blank have stated (Arch. exp. Path. Pharm., 20,377) that hippuric acid is decomposed by trypsin ; this was not confirmed ; possibly the trypsin they used was contaminated with the fat-splitting ferment of the pancreas. W. D. H. Diastatic Functions of Indigo-yielding Plants. By L. BR~AUDAT (Compt. rend., 1899, 128, 1478-1480. Compare this vol., i, 232).-The indigotic fermentation of the leaves of Isatis uZpina, which is brought about by a hydrolytic diastase and an oxydase present in the leaves, is promoted by t,he presence of ammonia, baryta, magnesia, and the carbonates of the alkali or alkaline-earth metals, either dissolved or in suspension in the fermenting liquor. I n presence of acids or neutral saIts, no formation of indigo is detected.The alkali only affects the action of the oxydase, the feeble oxidising power of which it increases. T. H. P.ORGANIC!

Compare Abstr., 1896, i, 582 ; 1898, i, 714).-Renewed experiments have shown that histidine is not formed in the hydrolysis of clupeine, salmine, or scornbrine with dilute sulphuric acid. Nor does clupeine yield lysine in these circumstances ; a substance, which has the composition of an amidovaleric acid and sublimes when heated cautiously, is obtained, however, along with another more soluble substance. And sturine is now found to yield some substances of a similar nature in addition t o the three hexon bases, arginine, histidine, and lysine. Protamines, therefore, must be subdivided into two groups : those of the one group, exemplified by sturine, yield all three hexon bases when hydrolysed; those of the other, namely, clupeine, salmine, and scornbrine, yield arginine only. If a protamine nucleus does form the basis of the albumin molecule, it must be one of the sturine type, since the proteids, like sturine, yield all three hexon bases.C. F. B. Preparation and Detection of Lysine. By ALBRECHT KOSSEL (Zeit. physiol. Chem., 1899, 26, 586-587).-From the products of decomposition of proteids, the bases are precipitated with phospho- tungstic acid, the precipitate is decomposed with baryta, from the filtered liquid the histidine and arginine are precipitated with silver sulphate and baryta (Abstr., 1898, i, 715), and the filtrate is evapor- ated to a syrup and mixed with alcoholic picric acid, when lysine picrate, C,H1,N20,,C,H,N,0,, separates ; this is recrystallised from a small quantity of boiling water.To convert it into the hydrochloride, it is dissolved in dilute hydrochloric acid, the picric acid is removed by extraction with ether,and the liquid is then evaporated to a syrup and mixed with a little hot alcohol, when lysine hydrochloride crys- tallises out as the mixture cools. C. F. B. Arginine. By WL. GULEWITSCH (Zeit. physiot. Chem., 1899, 27, 178-215, and 368--369).-Arginine has been prepared from the testicles of salted herrings, and a number of its salts examined. Most of these have been prepared before (Schulze and Steiger, Abstr, 1886, 725 ; Hedin, Abstr., 1895, i, 160 ; 1896, i, 193) ; the hydrochloride however, as crystallised from alcohol, contained IH,O (Schulze and Steiger describe i t as anhydrous; Hodin, with 1H20), and the copper nitrate compound, 3&H,O (3H,O, according to these authors).A crystalline phosphotungstate, 3CGH,,N,0,,2H,P0,, 24 WO, + 1 OH20, and a rnercurichloride compound, melting and decomposing at 186-189O are described, apparently for the first time: in the latter, the ratio Hg :C1 is 1 : 1, and hence the compound is of the nature of a mercuric derivative of the base. The hydrochloride melts and decomposes at about 209" when anhydrous, the nitrate melts partially and begins to decompose at 175' ; the acid nitrate (with 2HN0,) melts and decomposes a t 144-5-1 45' ; the copper nitrate compound melts at 112-114", or at 232-234" with decomposition when anhydrous ; the copper sulphate compound melts at about l l O o , and when anhydrous decomposes at 235-238O j the silver nitrate compound VOL.LXXVI. i. 3 m834 ABSTRACTS OF CHEMICAL PAYERS. (with AgNO,) decomposes a t 164', the acid compound (with HNO,,AgNO,) melts and decomposes at about 180'. The specific rotation, [ aJD, calculated for the arginine, is about 12.5' for the hydro- chloride in aqueous solution, and is raised to about 25.5' by addition of excess of hydrochloric acid, and lowered to about 11 -5' by addition of a slight excess of barium hydroxide; for the nitrate, the value is about 12*5', raised to about 2 5 ~ 5 ~ by the addition of excess of acid (about, 1 3 O for the compound with HNO,,AgNO,) ; for the sulphate 10*5O, raised to 22.5'.A silver derivative of arginine (compare KosseI, Abstr., 1898, i, 715) was precipitated by adding silver nitrate to a solution of one of the silver nitrate compounds, until the ratio AgNO, : C,H,,N,O, was 2 : 1, and then adding just enough alkali t o combine with all the nitric acid present ; the resulting compound is amorphous and unstable in daylight ; it appears to consist mainly of C,H,,N40,Ag, + H,O mixed with a little C,H,,N,O,Ag, + H,O. The arginine itself was prepared by boiling the testicles with dilute sulphuric acid (1 : 2) for 8 hours, neutralising with chalk, adding silver nitrate to the concentrated filtrate until a drop gave a brownish precipitate with baryta water, saturating the filtered liquid with baryta water, washing the precipitate of arginine-silver with water, decom- posing it with hydrogen sulphide, removing carbonic acid with baryta water, neutralising with nitric acid and adding silver nitrate and ammonia alternately so long as a small quantity of either produced a further precipitate, filtering from the precipitated silver compounds of histidine and thymine, neutralising with nitric acid and evaporating t o the cryst'allising point, purifying the crystals of the silver compound (with HNO,,AgNO,) by recrystallisation from hot water, converting these into arginine-silver, decomposing this with hydrogen sulphide, and evaporating the filtrate to the crystallising point.Arginine decomposes at 207-207*5O, and has the properties of an alkali ; for instance, it absorbs carbonic anhydride from the air.Its molecular weight determined by cryoscopic methods, using water as solvent, agrees with that required by the formula CGHI4N40,. The dibemoyl derivative, CGHl2N4O2Bz2, forms needles or tablets belonging to the rhombic system, melts a t 217*5--218O, and in its properties shows much resemblance to ornithuric acid. The discrepancy between the author's polarimetric results and those of Schulze and Steiger is due to the fact that these observers stated the rotation of an aqueous solution of arginine nitrate (of vegetable origin) in degrees of the Ventzke scale, not in angular degrees. This being so, the rotation proves to be practically identical with that of arginine from animal sources, and there is no reason therefore to suspect the existence of two dextrorotatory arginines.By WL. GULEWITSCR (Zed. physiol. Chem., 1899, 27, 292--296).-Thymine, obtained by boiling herrings' testicles with dilute sulphuric acid (preceding abstract), was compared, as regards crystalline form, with that from the thymus and from the milt of the sturgeon (Kossel, Abstr., 1894, i, 156, 631 ; 1896, ii, 537). The crystals sometimes have a rounded outline, but frequently are bounded by straight lines meeting at 90' or 45' ; they show extinction parallel C. F. B.

The butyric fer- mentation is accidental and does not occur, if, after the ferment is introduced, the milk is put into flasks which have been carefully cleaned. H. R. LE S. By V. HARLAY (J.

Compare this vol., i, 656).-The results confirm the author's statement (Zoc. cit.), that the absence of a turbidity, on the addition of nitric acid to the filtrate from the products of digestion, is no proof that the digestive action is ended.The digestive action of pepsin and pancreatic juice on albumin is quite analogous to that on fibrin, except that pancreatic juice acts much more slowly on the former, and digestion is not com- plete even after the addition of sodium hydrogen carbonate. The juice of Russula dezica gave a colour change of red to green with the liquid from the pepsin digestion, and of red to black with that from pancreatic digestion. Tyrosine was found in the liquid from the action of the pancreatic juice on albumin. Two New Reactions of the Products of the Digestive Action of Pepsin and Pancreatic Juice, Ey V. HARLAY (J.Pharrn., 1899, [ vi], 9, 468-470. Compare preceding abstract).-The green colour produced by the action of the juice of RussuZa delica on the products of the digestive action of pepsin on albumin or fibrin, is changed to a bright red by the addition of a few drops of an alkali, but is restored when acid is afterwards added. On similar treatment, t.he dark brown liquid resulting from the digestive action of pancreatic juice does not show a colour change. With liquids resulting from a pancreatic digestion of albumin or fibrin, bromine water produces a precipitate which redissolves when shaken, giving rise to a red liquid, changing to a reddish-purple on further addition of bromine, a brownish-purple precipitate being finally formed, With liquids resulting from the digestive action of pepsin, only a slight turbidity and a faint, dirty violet coloration are produced, a yellowish precipitate being formed on the addition of excess of bromine, By JEAN EFFRONT (BUZZ.SOC. Chim., 1899, [iii], 21, 676--680).-The use of alcohol for the separation of the products of peptic digestion has been proposed by several experimenters, but little is definitely known regarding the actual solubility of the substances concerned.

It is only by working with neutral solutions that concordant results can be obtained. N. L. Histones. By IVAR BANG (Zed. Physiol. Chem., 1899,27,463-486). -The term histone has been applied to various proteids; i t was first used by Kossel for a proteid extracted from nucleated red blood cor- puscles with hydrochloric acid. Next Lilienfeld separated from the thymus, spleen, and testis a histone combined with nuclein (nucleo- histone) ; then Mathews regarded the substance arbacin, which he prepared from the sea-urchin, Arbacia, as a histone, and, lastly, Schulz regards globin, the proteid constituent of haemoglobin, as belonging to the same category.These four substances differ from each other very considerably in elementary composition, and the present inquiry was to determine whether the histones should be regarded as a separate, well characterised group of proteids. The substances examined were the four just mentioned, except that, in place of arbacin, the similar substance scombrine, prepared from mackerel sperm, was used. It is admitted that the histones give no single distinctive reaction, but from the fact that all give a certain number of reactions, the group is con- sidered to be sufficiently well defined, These reactions are the follow- ing: (1) They are precipitated by ammonia, and the precipitate is insoluble in excess of that reagent in the presence of ammonium salts ; (2) they are precipitated by nitric acid; the precipitate dissolves on heating, and reappears on cooling ; (3) they are precipitated by boiling in a neutral solution, except when the solution contains little or no salt ; (4) neutral solutions are precipitated by alkaloidal reagents, and (5) they precipitate albumin from its solutions.By THOMAS BURR OSBORNB (J. Amer. Chem. Xoc., 1899,21, 486-493).- The author finds that the proteids hitherto prepared are definite com- pounds of protein with mineral acids, or mixtures of such compounds. All these substances are acid to phenolphthalein, slightly acid or neutral to litmus, and alkaline to lacmoid or tropzeolin; by means of the last two indicators, it is found that proteids are capable of com- bining with further quantities of acid.In the case OF edestin, the nature of the combined acids depends on the method of preparation ; thus, when precipitated from sodium chloride solution, it contains mostly hydrochloric acid, and when thrown down from ammonium sulphate solution, it is united to sulphuric acid. When either product is suspended in water and made neutral to phenolphthalein by dilute caustic potash, the alkali unites with the acid from the edestin and the proteid is precipitated in the free state. Thus obtained, edestin is insoluble in water, but dissolves readily in decinormal acid or alkali, It is soluble also in 10 per cent.aqueous W. D. H. Definite Compounds of Proteids [with Mineral Acids].ORGANIC CHEMISTRY. 837 sodium chloride ; the solution is neutral to phenolphthalein, but alkaline to litmus and lacmoid, and when heated on a water-bath is slowly and imperfectly coagulated. From this brine solution, the edestin is slightly precipitated by saturating with salt, more SO by saturating with magnesium sulphate, and completely on saturating with sodium sulphate at 34O. On dialysing the liquid obtained by gradually mixing a 10 per cent. sodium chloride solution of edestin with an equal volume of the same salt solution containing 1 C.C. of decinormal hydrochloric acid per gram of edestin, a crystalline deposit is obtained, of which the part insoluble in water consists of edestin monohydrochZm*ide ; it separates from a diluted brine solution in octahedral crystals.On treating edestin with insufficient hydro- chloric acid to completely dissolve it, the part dissolved consists of a dilqdrochloride which is soluble in water, but is reprecipitated by the addition of very small quantities of alkali salts. It dissolves in 10 per cent. sodium chloride solution, giving a liquid from which, on dialysis, it separates in octahedra ; it crystallises well from a diluted brine solution, and in either aqueous or salt solutions is acid to phenol- phthalein or litmus, but alkaline to lacmoid. Sodium chloride solutions of both derivatives give a flocculent precipitate when heated at 9 9 O , and, on saturation with sodium chloride, magnesium sulphate, or sodium sulphate, behave similarly to edestin.T.

Xoc., 1899, 21, 477-485).-1n the preparation of crystallised albumin, the author finds that instead of adding acetic acid to the semi-saturnted ammonium sulphate solution of egg-albumin, as recommended by Hopkins and Pinkus (Abstr., 1898, i, 456), the addition of hydrochloric acid, equivalent in quantity to the acetic acid, gives a quicker pre- cipitation of the substance. The products thus obtained, which are acid tjo litmus or phenolphthalein, but alkaline to lacmoid or tropaeolin, are regarded as compounds of albumin with acids. Of the first crop of crystals deposited, 1 gram required for neutralisation to litmus 2.05 C.C.of N/10 KOH, and to phenolphthalein 1.30 c.c., the difference being 0.75 C.C. The mean difference for all the crystals obtained both by means of acetic and hydrochloric acids was 0.71 C.C. If the number 15,000, as given by Sabanbeff (Abstr., 1890, 1215), for the molecular weight of albumin is correct, and the acid and albumin unite in molecular proportion, then 1 gram of albumin would require 0.67 C.C. of the alkali ; also, if 3 mols. of acid combine with 1 mol. of albumin, then 1 gram of albumin would require for its neutralisation 2 C.C. of N/10 alkali. The acid with which the albumin is united is almoht entirely, if not altogether, organic, but its nature is unknown. The coagulation of albumin is greatly influenced by the amount of acid present ; exact neutralisation to phenolphthalein prevents coagula- tion, which, however, readily takes place on the water-bath in the presence of 3 mols.of acid to 1 of albumin. Pure albumin gives in aqueous solution a mean specific rotation [ aID - 28' 42' ; in decinormal acid or alkali solution, the rotation increases slightly with the amount of alkali or acid present. Several analyses are quoted in the paper. T. H. P.838 ABSTRACTS OF CHEMICAL PAPERS. Crystallisation of Blood-Albumin. By 5. GRUZEWSKA (Compt. rend., 1899, 128, 1535--1537).-The author has succeeded in cry stallising blood-albumin from the guinea-pig, cat, ox, and adder. The blood is collected in a 0.2 per cent. solution of sodium oxalate and centrif ugnted, the cold residue being mixed with a saturated solution of ammonium sulphate to eliminate the globulines, which are filtered off.The filtered liquor is then kept cool by a freezing mixture for a time varying with the nature of the serum (22 hours a t - 1" in the case of guinea-pig's blood), and when left at the ordinary tem- perature crystals of albumin are obtained. The serum of the guinea- pig yields five different forms of crystals, some apparently belonging to the hexagonal system. T. H. P. Crystalline Forms of Albumin, By ARTHUR WICHMANN (Zeit. phgsiol. Chern., 1899, 27, 575-593).-The author has investigated the crystalline forms of egg-albumin, serum-albumin, and lactalbumin, and concludes that they are probably identical, or at least isomor- phous; thus, on adding ammonium sulphate to an aqueous solution of a mixture of egg- and serum-albumin or of all three albumins, only one crystalline modification can be obtained.It seems probable also, from their optical behaviour, that the four different crystalline modifications of serum-albumin described by Michel and Giirber belong to the hexagonal-pyramidal class of the hexagonal system, and are all derived from the same fundamental form. The crystals of serum-albumin are as a rule larger and better defined than those of either egg-albumin or lactalbumin ; all three forms, however, closely resemble one another in completely absorbing the colouring matter from dilute dye solutions, becoming coloured in the process although otherwise remaining unchanged. It is noteworthy, however, that when the coloured crystals are dried they become amorphous through- out their substance, without losing their crystalline shape, whilst the undyed crystals, under similar treatment, fall to pieces in becoming amorphous. Mineral salts such as gold chloride, silver nitrate, and cadmium borotungstate are also readily absorbed by crystalline albumin ; potassium permanganate, which readily acts on aqueous albumin, forming a gelatinous substance and a brown precipitate, is apparently without action on albumin crystals, beyond tinting them yellowish-brown and rendering their material amorphous without changing their shape. The crystalline compound of ammonium sulphate with albumin, containing about 5 per cent. of the latter, described by Harnack (Abstr., 1891,476), is shown to consist merely of crystals of ammonium sulphate containing inclusions of aqueous albumin. When crystals of egg albumin (double rgfraction positive) are left in contact with the mother liquor, coagulation occurs and the mass becomes isotropic ; after some time, however, crystals separate having negative double refraction which differ therefore from the original form. On warming, the tmorphous variety is regenerated, but this, when left, undergoes transformation into the negatively refracting modification. The crystalline, soluble variety, which also exists in an amorphous form and appears to be monotropic, is termed a-albumin,ORGANIC CHEMISTRY. 839 and the name P-albumirt is given to the insoluble, amorphous form, which becomes negatively double -refracting and is enan tio t ropic. W. A. D. Composition and Hydrolysis o f the Albumin of the Carob Seed (Ceratonia Siliqua). By EMILE BOURQUELOT and HENRI H~RISSEY (Compt. rend., 1899, l29,228--231).-When the albumin of the grain of Cerutonia siliqm is heated with dilute sulphuric acid (4 : 100) at l l O o , it yields a mixture of mannose (compare Alberda van Ekenstein, Abstr., 1898, i, 11 8) and galactose, both of which the author has isolated in a crystalline form and identified by various physical pro- perties and chemical reactions. The quantities obtained are consider- able and no other sugar seems to be formed. The nature of the insoluble portion, amounting to about 1/7 of the albumin employed, is under investigation. C. H. B. By WILHELM VAUBEL (J. 2”. Chern., 1899, 60, 55-71).-A review of the methods by which the molecular weight of proteids can be determined : These comprise (1) the freezing point or boiling point of a dilute solution; (2) the analysis of proteid salts, especially metallic compounds ; (3) the determination of the total percentage of sulphur, and the per- centage which will act on alkaline lead solutions ; (4) the estima- tion of the proportion of halogen, &c., in substituted proteids; (5) the estimation of the quantity of the various products of hydro- lysis, especially tyrosine, aspartic acid, and arginine. A summary is given of the most reliable of the results obtained by these methods with oxyhaemoglobin, globin (from haemoglobin), crystallised serum-albumin, conglutin, egg-albumin, and casein. The author concludes that, in the case of the albumins, the data are sufficient to give a satisfactory estimate of the molecular weight, but that further information must be obtained with regard to the albumoses and peptones. Properties of Nucleo-Proteids. By FILIPPO BOTTAZZI ( R e d . Accud. dei LLinc., 1899, 8, 505--513).--The nucleo-proteids examined were extracted from very fresh animal organs in such a way as to remove all enzymes, the proteid and biliary substances, and the hsmoglobin. The experiments were made in Wolff bottles so arranged that no putrefying action took place. Towards sodium carbonate solution, nucleo-proteids show an acid behaviour, the alkalinity of the solution being gradually destroyed, On adding to a solution of splenic or hepatic proteid sufficient oxy- hzemoglobin solution to cause the liquid to show distinctly the two absorption stria? in the spectroscope and alIowing to remain, it is found that, after 3 to 5 hours, all traces of the oxyhaemoglobin have disappeared ; if an excess of the latter is added so that the absorption stris unite t o form a wide band, the latter gradually becomes sepa- rated into two distinct parts, which finally disappear. After this, thc liquid assumes a dirty, brownish colour, but at no period of the action can the spectrum of hsmoglobin, or of methaemoglobin, be detected. Although no important differences between the actions of splenic and hepatic proteids were observed, in all these experiments the nucleo- Molecular Weight of Proteids. T. M.

The only substance exerting a decomposing action on oxyhamoglobin similar to that attributed t o the nucleo-proteid is sodium carbonate, and this is found t o have a very much slower action. When glycogen is dissolved in solutions of hepatic proteid under conditions which do not allow of the presence of an enzyme, the glycogen disappears ; the best temperature is 38-40°, and it is not necessary for the liquid to be aerated. Cellular Membrane of Gentian Root. By EMILE BOURQUELOT and HENRI H~RISSEY (J. Phuwn., 1899, [vi], 9, 330-331. Compare Abstr., 1898, i, 607, and 1899, i, 93).-Twenty-five grams of powdered gentian root which had been previously treated with cold water, boiling alcohol, and dilute sulphuric acid, were treated with a mixture of 125 grams of sulphuric acid and 42 grams of water, and left at the ordinary temperature for 24 hours ; the volume was then made up to 1000 c.c., and the filtrate, after further dilution t o 5000 c.c., was boiled for 6 hours. The sulphuric acid was removed by means of chalk, the liquid evaporated, and the residue recrgstallised from boiling absolute alcohol, when a crystalline sugar was obtained which gave [a],+52*51, and from its melting point (143-144'), and that of its oeazone (205O), is identified as dextrose. By PAUL CAZENEUVE and P. BRETEAU (Bull. Xoc. Chim., 1899, [iii], 21, 427--428).-After being subjected t o the action of boiling water and then dried at 135O, haematin is insoluble in cold dilute ammonia solution. Hsematins from the blood of oxen, horses, and sheep, after being washed with boiling water on the filter for an hour or so, all showed diminished percentages of carbon, oxygen, nitrogen, and iron. The action of the hot water is thus one of oxidation. T. H. P. H. R. LE S. Decomposing Action of Water on Hamatins. T. H. P.

ANALYTICAL CHEMISTRY. 801 Analytical Chemistry. Asbestos Filters. By OTTO LOHSE (Ber., 1899,32,2142-2146).- The author describes a modified asbestos filter tube constructed on the same principle as a Gooch filter (Clwn. News, 1878, 37, 181). It consists of a glass tube, 12 cm. long and 15 mm. in diameter, closed at one end and slightly widened at the open end; the closed end is perforated with a number of minute holes, so arranged that the tube can be heated without risk of breaking. The advantage the tube appears to have over the ordinary Gooch filter is that the precipitate can be somewhat more conveniently heated in a reducing atmosphere. Convenient forms of aluminium holder, desiccator, and tongs for removing the asbestos from the tube, are also described. J. J. S.802 ABSTRACTS OF CHEMICAL PAPERS.Weighing Corrosive or Fuming Liquids. By RUDOLF SCHWARTZ (Cheni. Zeid., 1899, 23, 451).-The apparatus is essentially a pipette, ending in two capillary tubes, and weighing about 2-3 grams. One end is placed in the liquid, and suction is applied a t the other end with a pump until the bulb is three parts filled; the top tube is then sealed. By removing the pipette and turning it upside down, it becomes possible to seal the other end, and the pipette is then reweighed. The pipette may be readily broken under water to obtain Apparatus for the Extraction of Liquids with Ether. By FRITZ BAUM (Chem. Zeit., 1899,23, 249-250).-Ether is boiled in a flask, and the vapour being condensed, the ether (or similar non-miscible solvent) flows down the condenser tube to the bottom of a cylindrical vessel containing the liquid (or solid matter) to be extracted.While ascending through the liquid, it dissolves any fatty matter, and when a certain quantity has collected on the top it is syphoned back into the boiling flask. An illustration is given. When the liquid has been thoroughly extracted, it is removed with a pipette, thus leaving plenty of room for the collection of the Estimation of some Inorganic and Organic Acids by means of the Volume of Hydrogen evolved on Treatment with a, Metal. By KARL ULSCH (Chem. Zeit., 1899, 23, 624-625).- Platinised iron (iron powder treated with solution of platinum chloride) is quantitatively acted on by fairly concentfated solutions of sulphuric, hydrochloric, and phosphoric acids, and the amount of these acids may be readily ascertained from the volume of hydrogen evolved.Phosphoric acid causes some trouble as the platinised iron gets gradually coated with ferrous phosphate, The process may also be extended to the estimation of oxalic, acetic, and lactic acids; the author has not, as yet, applied it successfully to By FRANZ FESSEL (Zeit. alza2. Chem., 1899, 38, 449-453 ; from Inaug. Dissert. Tech, Inst. Univ. Wui*xbus.g, 189S).-The author has submitted to a careful study the conditions under which the reaction KIO, + 5KI + 6HC1= 6KC1+ 3H,O -!- 61 can be employed for the estimation of a free acid. It is important that both the iodate and the iodide should be in excess, otherwise too little thiosulphate will be required.A deficiency of the former will be indicated by n liberation of iodine on adding iodate to the colourless liquid at the end of the titration. A deficiency of the latter is shown by the deposition of solid iodine. Boiled water must be used, since carbonic anhydride liberates iodine from the mixture of iodide and iodate. The iodide solution (10 per cent.) should be preserved from air and light, but even if coloured by free iodine it may be used after decolorising with thiosulphate. Excessive dilution lowers the results, but as this seems to be due to a retardation of the reaction, it is recommended that where great dilution is unavoidable there should be a delay of half an hour before titrating the liberated iodine. the required solution.

KJELDAHL points out that, in applying the iodometric method to the estimation of ammonia, accurate results are only obtained by working strictly in tho same manner in all cases. Xulphnric acid either alone or after absorption of ammonia does not immediately liberate the theoretical amount of iodine from a mixture of iodide and iodate, but the deficiency in the quantity of thiosulphate required will be the same in the two cases if the volumes of the solutions are equal. The thiosulphate should be standardised by titrating with it the acid to be employed both before and after the absorption of ammonia from a known weight of an ammonium salt.Delicate Reaction of Hydrogen Peroxide. By EDGAR S. BARRALET (Chem. News, 1899, 79, 136).-Ferrous ferrocyanide, pre- pared from a solution of a ferrous salt and potassium ferrocyanide, is quickly turned deep blue by hydrogen peroxide, even when the amount of the latter is as little as 1 part in 165,000 parts of water. M. J. S. D. A. L. Estimation of Hydrochloric Acid in the Stomach Contents. By GIUSEPPE SIRINGO (Gaxxetta, 1899, 29, i, 476--479).-The author finds that the use of Gunzberg’s reagent--an alcoholic solution of phloroglucinol and vanillin (Abstr., 1888, 6 17)-does not afford an infallible test for the presence of hydrochloric acid in the stomach contents, and suggests instead the employment of salts of nitro- hydroxylamine which even in very dilute solutions are decomposed by hydrochloric and the other more energetic acids, nitric oxide being immediately evolved in almost theoretical quantity ; the weak organic acids, as also acid phosphates, me without effect.5 C.C. of the stomach contents are placed in a graduated tube which is filled with mercury and inverted in a mercury trough; a small piece of the nitrohydroxylamine salt, for instance, the sodium salt, is then introduced into the tube and after a few minutes the volume of the evolved gas is read off and corrected in the usual way. Estimation of Chlorine, Bromine, and Iodine. By J. BOUGAULT (J. Pharm., 1899, [vi], 10, 18--20).-Instead of converting the mixed silver haloids into silver chloride, they are reduced by pure metallic zinc and dilute sulphuric acid (1 of acid to 10 of water), and the precipitated metallic silver weighed. The reduction takes place easily and the results obtained are accurate. Detection of Chlorates, Bromates, and Iodates in the Presence of Each Other. By DIOSCORIDE VITALI (Chem.Cents.., 1899, i, 1083--1084 ; from Boll. Chim. Fwm., 38, 201--209).-When manganous sulphate is treated with sulphuric acid and potassium bromate, a violet-red solution is obtained ; this coloration is not due to permanganic acid, but to a manganic salt, Chlorates or iodates do not give this reaction. On boiling, the manganese is completely precipitated as hydrated dioxide. Salts of hydroxylamine (but not the free base) act on iodates in the cold with liberation of iodine ; bromates are only reduced on heating, and chlorntes are not affected at a l l ; salts of phenylhydrazine act similarly. Phosphorous and hypophosphorous acids do not act on T.H. P. H. R.

The author recom- mends the following process for the separation of the three com- pounds. bromates are alone precipitated; the silver compounds are then de- composed with hydrogen sulphide, and after filtering from the silver sulphide, the excess of the former is expelled by gentle warming, and the filtrate neutralised with soda and concentrated.

L. DE K. [Detection and Estimation of Small Amounts of Iodine in Cuprite and Malachite.] By WILHELM AUTENRIETH (Chem. Zeit., 1899, 23, 626--627).-The finely divided mineral is fused with 3-4 times its weight of pure sodium hydroxide (from metal) and a small quantity of water in a nickel crucible; the mass is then extracted with water, the filtered solution transferred to a glass cylinder and mixed with 10-20 C.C. of chloroform, a few drops of a 1 per cent. solution of pure sodium nitrite solution, and then acidified, while well cooled, with 20 per cent. sulphuric acid; after vigorous shaking, the colour of the chloroform solution is compared with that produced by the addition of a known quantity of potassium iodide solution (0.0001 gram iodine in 1 c.c.) to 20 C.C.chloroform, several C.C. of saturated sodium sulphate solution, dilute sulphuric acid, and a little sodium nitrite solution. The results are correct to within 0.1 milli- gram of iodine, If siliceous ores are present in the mineral, it is necessary to filter after fusing and rendering acid with sulphuric acid. The fusion must not be carried out at too high a temperature, as in such circumstances the sodium iodide volatilises. J. J. S. Detection of Fluorine in Wine. By GIULIO PARIS (Chem. Zeit., 1899, 23, 685 - 686).--The ash obtained from 50 C.C. of wine is mixed with a little precipitated silicic acid, introduced into a platinum crucible, and 0-5-1 C.C.of sulphuric acid added. The crucible is then covered with an inverted lid containing cold water, the under side being also moistened with a drop of water. The mixture is now heated over a very small flame for 5 minutes, and whan cold the drop of liquid adhering to the lid is put on to a slide covered with a thin layer of Canada balsam, and a few particles of sodium chloride are added. After about an hour, the slide is examined under the micro- scope for the very characteristic crystals of sodium silicofluoride. L. DE I(.

L. DE K.ANALYTICAL CHEMISTRY. 805 Estimation of Sulphuric Acid in the Presence of Iron. By GEORG LUNGE (Zeit. ccno~g. Chem., 1899, 21, 194-200).---An answer to Kuster and Thiel (this vol., ii, 247).-A comparison of the results obtained in the estimation of sulphur in iron pyrites by the author's and Kuster and Thiel's methods shows that there is no practical differ- ence in the results obtained, being 49.93 per cent. and 49.86 per cent. respectively, and the time employed on each method is about equal. In the estimation of sulphur in pyrites residues, the results obtained by the different methods are as follows: Watson-Lunge, 1.96 per cent.; Meineke's, by fusion with sodium carbonate and potassium chlorate, 2.00 per cent, ; Lunge's ammonia method, 1.94 per cent. ; Kuster and Thiel's, 1.94 per cent. ; Meineke's, by reduction with zinc (this vol., ii, 518), 1.92 per cent. Valuation of Persulphates. By G. H. MONDOLFO (Chenz. Zeit., 1899, 23, 699)-2 or 3 grams of the sample are dissolved in 100 C.C. of cold water, and 10 C.C. then heated a t 60-80" in a stoppered bottle with half a gram of potassium iodide for 10 minutes. The liberated iodine is titrated with N / l O sodium thiosulphate, 1 C.C. of which represents 0.0114 gram of ammonium, or 0.0135 gram of potassium persul p hate. Gas Washing Apparatus. By OTTO FOERSTER (Chem. Zed., 1899, 23, 196-l97).-The apparatus is based on the principle of the dephlegmator used in fractional distillation.The steam evolved when boiling a solution of an ammonium salt (such as a reduced nitrate) with excess of alkali, partly condenses, and when a certain quantity of liquid has accumulated, it is syphoned back into the boiling flask. By this means, the liquid cannot become over concentrated whilst the ammonia is still fully expelled. The Diphenylamine Test f o r Nitric Acid in Natural Waters. By RAFFAELE CIMMINO (Zeit. anal. Chenz., 1899, 38, 429-431).-l'he sensitiveness of this test depends greatly on the mode of performing it. That recommended by Emmerich and Trillich has hitherto been the most sensitive, being capable of detecting nitric acid at a dilution of 1 : 100,000, but by the addition of a little hydrochloric acid the sensitiveness is increased tenfold.The reagent employed therefore is a solution of diphenylamine and sulphuric acid in 5 per cent. hydro- chloric acid ; three or four drops of this reagent are added to 1 C.C. of the liquid to be tested, then 2 C.C. of concentrated sulphuric acid, and the whole shaken. I n presence of nitric acid, the mixture acquires a blue colour. No other constituent of natural water gives a similar reaction. M. J. S. Estimation of Ammonia and Nitric and Nitrous Acids in Natural Waters. By LUDWIG W. WINKLER (Chenz. Zeit., 1899, 23, 454-455 ; 541).-Preformed ammonia may be estimated without pre- vious distillation by removing the calcium and magnesium salts by means of sodium hydroxide and carbonate ; the clarified solution may then be at once Nesslerised.If too little standard ammonia has been added to the comparison liquid, it does not do to add a little more, but a fresh solution must be prepared. To obviate this, and also to save the E. C. R. L. DE K. Two drawings are given. L.

Nitrous acid is estimated by the amount of iodine liberated by the addition of hydrochloric acid and potassium iodide; the liquid is then titrated with standard solution of sodium thiosulphate, using starch-water as indicator. To get trustworthy results, the air should be excluded, which is best effected by operating in a sufficiently small flask with narrow neck, and displacing the air by carbonic anhydride generated by dropping into the acid liquid a sufficiency of solid potassium A Source of Error in the Estimation of Nitric Nitrogen by Ulsch’s Method. By L. BRANDT (Chem.

By GEORG VON KNORRE and KURT ARNDT (Be?*., 1899, 32, 2136-2141).-As the usual methods for the estimation of nitric oxide, namely, (1) ab- sorption by solution of a ferrous salt; (2) titration with potassium permanganate; (3) conversion into nitric peroxide by the aid of oxygen, are considered unsatisfactory, the authors have elaborated another method which consists in passing the gas, together with an excess of hydrogen, through a Drehschmidt’s platinum capillary tube heated to bright redness and measuring the contraction.Accord- ing to the equation 2 N 0 (2 vols.)+ 2H2 (2 vols.)=N, (1 vol.)+2H20, the amount of nitric oxide is equal to 2/3 of the contraction. Vory good results have been obtained by this method, but it is absolutely necessary that the mixed gases should pass very slowly through the capillary, as otherwise a certain amount of ammonia is formed. The method also admits of the estimation of nitrous oxide in the presence of nitric oxide, From the equation N,O (1 vol.) +H, (1 vol.)= N, (1 vol.) + H,O and the one given above, it follows that if x = vol. of nitric oxide and y = vol.of nitrous oxide, then x + y = P (volume of mixture), 1.5 x +y = C (contraction on leading through the capillary, and x = 2(C - V). already advocated the use of Rochelle salt. hydrogen carbonate.

Detection, and Estimation of Free Phosphorus in Oils and Fats. By EMILE LOU~SE (Conzpt. rend., 1899, 129, 394-395).- When a solution of silver nitrate is added to a solution of phosphorus in oil, the silver solution is reduced, and a black precipitate is pro- duced as long as any free phosphorus is present.By previously mixing the oil with 20 times its volume of acetone, the production of any tur- bidity is prevented when the aqueous silver nitratme solution is added. A 10 per cent. and:a 1 per cent, solution of silver nitrate are prepared, and these titrated by taking 5 grams of oil, containing a known quantity of phosphorus, and diluting to 100 C.C. with acetone. To 10 C.C. of this solution, the 10 per cent. silver nitrate solution is added drop by drop until the filtered liquid is no longer darkened in colour on the addition of another drop of silver nitrate, Suppose two drops of the silver nitrate solution were insufficient, but that after the addition of three drops the filtered liquid was not darkened on the addittion of another drop, then evidently the correct amount of silver nitrate solution was between two and three drops.To determine the exact amount, another 10 C.C. of the solution are taken, two drops of the 10 per cent. solution added, the liquid filtered, and then the 1 per cent. solution added drop by drop until the filtered liquid is not darkened in colour by the further addition of silver nitrate, I n this way, the strengths of the silver solutions in terms of phosphorus are ascertained. The determination of an unknown amount of phosphorus in an oil is carried out in exactly the same way. To obtain drops of exactly the same size, Duclaux’s apparatus was used. H. R. LE S.

Compare Abstr., 1897, ii, 344).-The assimilable phosphoric acid in basic slag is in the form of tricalcium phosphate. The slag contains also calcium phosphates of higher basicity, iron phosphates, iron silicophosphates, calcium silicophos- phates, calcium oxide and carbonate, silicon chiefly in combination with calcium, iron oxide, sulphide, and carbonate, $c. The difficulties in the way of determining the tricalcium phosphate by extraction with citric acid are the presence of lime, which neutralises some of the acid, and the dissolution of a portion of the silicate, most of which is precipitated with the molybdate, redissolves in ammonia, and is again precipitated by the magnesia mixture.I n this way, 0.01 and 0.02 gram of SiO, will cause an error of 0.6 and 1-27 per cent. in the phosphoric acid. This source of error and the error (in the other direction) caused by the presence of lime, can be avoided by altering the process, but the presence of iron in the slag involves another difficulty, since iron compounds diminish the solubility of tricalcium phosphate in citric acid.It is concluded that the error of the Wagner method is as much as 2-3 per cent., and varies according to the nature of the slag. With slags which do not contain much total phosphoric acid and silica, relatively little soluble phosphoric acid, but much lime and iron, the results will be too low ; whilst with slags which contain much phosphoric acid (both total and soluble) and silica, but only a little lime and iron, the results for soluble phosphoric acid may be even higher than the total phosphoric acid. Estimation of Boric Anhydride in Boracite. By RUDOLF SCHWARTZ (Chenz. Zeit., 1899, 497).-Gilbert’s process of carefully estimating the other constituents of the mineral and thus obtaining the boric anhydride by difference is difficult of application.Hdnig and Bpitz’s volumetric process yields very good results. In order to prepare the solution for titration, 1-2 grams of the finely powdered sample are digested for several hours with 100 C.C. of water, and 5-10 C.C. of hydrochloric acid; if a reflux apparatus is employed, half-an-hour’s heating on the water-bath will be sufficient. The filtrate is carefully neutralised with N/5 soda, using methyl-orange as indi- cator. The solution may also be prepared by attacking the mineral suspended in water with carbonic anhydride for about half-an-hour ; manner. L. DE K. Basic Slag. N. H. J. M.ANALY'I'ICAL CHEMISTRY. 809 after remaining for a few hours in a closed flask, the liquid is filtered, evaporated to about 20 c.c., and carefully neutralised with dilute hydrochloric acid, using methyl-orange as indicator ; the carbonic anhydride is then expelled by boiling for a short time.The liquid obtained in either way is then titrated with N/5 soda i n the presence of glycerol, using phenolphthalein as indicator (Abstr., 1897, ii, 159). By ADOLPHE CARNOT and E. GOUTAL (Chenz. Cent?.., 1899, i, 903; from Anal. Chim. Appl,, 4, 73-'76).-Blair separates carbon from iron by treating the sample with a solution of potassium cuprous chloride containing 15 C.C. of hydrochloric acid in 200 C.C. The authors having tested the method, state that the temperature should not exceed 70°, otherwise there will bea loss of carbon.They, however, prefer their own process of treat- ing the sample at 95" with the slightly acidified copper solution for about half-an-hour in a current of carbonic anhydride. Ferromanganese with more than 75 per cent, of manganese should be treated in the cold. The drying of the carbonaceous residue is often a source of By JOSEF SPULLER (Ch'em.

Two Simple Methods for estimating Carbonic Anhydride in Quick Lime, Limestone, Animal Charcoal, Marls, &c., and Soils. By V. SCHENKE (Chein. Zeit., 1899, 23, 612--614).-The first method and apparatus present no novel features. A new process is proposed for the estimation of carbonic anhydride combined with lime and magnesia in soils.The soil is ignited, finally over the blowpipe and the ash weighed; i t is then moistened with ammonium carbonate and again dried over a low rose-burner ; the increase in weight represents the carbonic anhydride in combination By E. WIGHTMAN BELL (Chern. Xews, 1899, 79, 135--136).--In the case of manures, 5 or 10 grams are boiled with about 150 C.C. of water, with or without addition of hydrochloric acid ; ammonia is then added to slight alkalinity, and is followed by barium carbonate to the extent of about double the weight of the manure taken, the boiling being continued for half-an-hour, The mixture is filtered, the precipitate is washed, and the combined filtrate and washings made up to 500 c.c., of which 50 to 100 C.C.are evaporated to dryness, along with a small quantity of ammonium oxalate, gently ignited, treated with hot water, and filtered. The filtrate is evaporated with hydrochloric acid and platinic chloride, and the estimation completed in the usual way. With soils, either the solution in hydrochloric acid is boiled, treated with ammonia, &c., as above, or the soil is moistened with strong sulphuric acid, gently ignited, boiled with water, treated with barium carbonate, boiled again, filtered, and an aliquot portion of the filtrate evaporated wit b L.

A. L. By E. BOHLIG (Zeit. anal. Chm., 1899, 38, 431--432).-Half a litre of the water is rapidly boiled down to 50 C.C. in a large porcelain basin, then strongly acidified with sulphuric acid, and evaporated without ebulli- tion until fumes of sulphuric acid are given off. The residue is then washed into a 200 C.C. flask with 1/50 C.C. of water, some barium carbonate added, and carbonic anhydride passed through the mixture as long as any is absorbed ; the insoluble matter is removed by filtra- tion and washing, the filtrate evaporated to dryness, and the dry residue digested with 50 C.C.of a mixture of equal parts of alcohol and water. The alkali carbonates dissolve in this menstruum, whilst all other carbonates remain undissolved. After filtration, the total alkalis present can at once be estimated by titration with N/10 hydrochloric acid. The potassium is then precipitated as platinochloride, and the sodium calculated from the difference. Estimation of Alkalis in Natural Waters. M. J. 8. Estimation of the Alkalis in Urine. By RICHARD P~IBRAM and GEORG GREGOR (Zeit. anal. Chem., 1899,38, 401--411).-With the object of establishing a method which, without loss of accuracy, should be sufficiently rapid and convenient for clinical purposes, the authors have examined the methods of Neubauer, Lehmann, Bunge, Salkowski-Munk and Heintz.Neubauer’s method is far from satisfactory, Lehmann’s process (Abstr., 1885, 609) is theoretically free from sources of error, and as it gives higher values for the potassium found than any of the other processes, it is presumed to be the most accurate. It may be improved by substituting concen- trated sulphuric acid for the ammonium sulyhate added before in- cineration of the urine residue ; a white ash is then much more rapidly obtained, and there is less danger of loss of alkali. Another im- provement introduced by Kretzschmar consists in evaporating to dryness, and drying at l l O o after the addition of barium chloride, ammonia, and ammonium carbonate. On treating the residue with hot water containing a little ammonia, the alkali chlorides can be washed out with great facility.Both this method and Bunge’s are, however, tedious. That of Salkowski-Munk is equally so, and of lower accuracy, whilst Heintz’s process is confined to the estimation of the potassium, and gives seriously low results, The authors there- fore propose a new process which gives results identical with those of Lehmann, but is more rapid and requires less caution on the part of the operator. 50 C.C. of urine aye mixed with 10 C.C. of dilute (1 : 10) sulphuric acid and R su$cient quantity of a 10 per cent. solution of barium permanganate (10-20 c.c.), and the mixture is boiled; after boiling for 10-15 minutes, a red coloration must still remain ; this is removed by a few drops of oxalic acid. Barium chloride is then added in small excess followed by ammonia and am- monium carbonate ; the precipitate is removed by filtration, and the filtrate evaporated in a platinum basin; the alkali chlorides tbueANALYTICAL CHEMISTRY.81 1 obtained are usually quite free from carbonaceous matter. Should magnesium be present, as may occur in all processes in which the alkalis are weighed as chlorides, it may be eliminated by keeping the chlorides at a dull red heat in a covered platinum crucible for an hour or longer, by which means magnesium chloride is converted into oxide. It is then desirable to estimate the total chlorine by silver, and the potassium by platinum, and calculate the sodium indirectly. M. J. S . 8eparati.x of Zinc from Nickel. By E. DOHLER (Chem. Zeit., 1899, 23, 399--400).-Zinc may be separated from nickel by precipi- tation with hydi.yen sulphide in the presence of free acetic acid when mineral acids we absent.Good results may be obtained by using a very large excess of acetic acid, but even then the precipitated zinc sulphide may be of a dark colour and contain an admixture of nickel sulphide. It may be freed from nickel by dissolving it i n dilute hydrochloric acid, which leaves most of the nickel sulphide un- dissolved, and after neutralising the filtrate with ammonia and adding sodium acetate and free acetic acid, again precipitating by means of hydrogensulphide, pure white zinc sulphide beingthen obtained. Instead of using sodium acetate and acetic acid, the neutralised solution may be advantageously mixed with sodium formate and formic acid ; the precipitate produced by hydrogen sulphide is then free from nickel, and needs no purification.L. DE K. Electrolytic Estimations and Separations, By LILY G. KOLLOCK (J. Amer. Chem. Soc., 1899, 21, 911-9228).-Some of the older methods for electrolytic determinations and separations in potassium cyanide solutions have been repeated. The exact conditions as to current density, arnpbrage and voltage and other factors have been worked out for the estimation of cadmium, silver, and mercury, and for the separation of silver, mercury, or gold from platinum, copper, zinc, nickel, or cobalt; of silver or mercury from cadmium or iron, and of gold from palladium. Mercury may be deposited from alkali sulphide solution under the following conditions : 25 C.C. of sodium sulphide are added to a solu- tion of mercuric chloride containing 0.1403 gram of mercury; this solution, diluted to 125 c.c., is electrolysed at 70" by a current of N.D.loo = 0.11 amphe, and voltage= 2.5, and, a t the end of 5 hours, the mercury is completely deposited, Copper can be deposited from nitric acid solution by using a current of N.D.loo = 0.09 and voltage = 1-9 in 5 hours a t 65" ; mercury can also be deposited in a similar manner.Cadmium is deposited from sulphuric acid solution in 5 hours at 65" when a current of N.D.roo = 0.078 aad voltage= 2.61 is employed. Mercury may also be estimated in a somewhat similar manner. The conditions necessary for the accurate determination of bismuth in citric acid, ammonium citrate, or potassium citrate solution have also been determined.I n the case of ammonium citrate, the solution is made ammoniaoal and is electrolgsed at 65', first with a current of 0.02 smptSre and 108 volts, the current beiag finally increased to812 ABSTRACTS OF CHEMICAL PAPERS. 0.09 amphre and 2.3 volts. A certain amount of bismuth peroxide is always deposited on the anode and must be weighed. A current of much ths same density was employed in both citric acid and potassium acetate solutions, and in the latter case the solution was made strongly alkaline by the addition of potassium hydroxide. Iron may be deposited in the course of 7 hours from a solution containing sodium citrate and free citric acid when a current of 0.58 ampere and 5.7 volts is employed, or in 4-5 hours at 50' with a current of 0.4-1 ampere and 7-11 volts.J. J. S. Precipitation of Cadmium by Hydrogen Sulphide. By ROBEE~T MELDRUM (Chem. News, 1899, 79, 170--171).-The author attributes failure to detect small quantities of cadmium, by means of hydrogen sulphide in the way usually employed, to the too liberal use of hydrochloric acid, which dissolves the sulphide. He has further investigated the precipitation by means of hydrogen sulphide of neutral solutions of cadmium sulphate varying in strength from 0.5 to 0.00125 per cent. Solutions from 0.5 to 0.25, in the cold give a curdy precipitate which settles quickly and a dense, opaque, yellow solution ; when heated to boiling, the precipitate becomes orange-yellow, settles rapidly, and turns paler on cooling, but does not regain its former colour; the solution is clear with a slight yellow tinge.Agitation while cooling, and when cold, makes the precipitate settle less rapidly and renders the solution opaque. Solutioiis containing from 0.2 to 0.02, yield less precipitate on boiling, give little or no precipitate in an hour in the cold, and the solution remains opalescent. Solutions of greater dilution (except the 0.00125, which shows no colour in a thickness of 2 inches) yield yellow solutions, but no im- mediate precipitate. The filtrates from the solutions of greater strength than 0.0175 per cent. are almost free from colour in a thickness of 2 inches, but from the solutions of still greater dilution the filtrates are always coloured. 5 y repeated filtrations, this colour may be re- moved from the 0.0175 to the 0.015 per cent.solutions but not from the weaker filtrates; these, however, deposit a small precipitate in 24 hours, but still retain a yellow colour. A colorimetric method of estimating cadmium is suggested for solutions not exceeding in strength 0.02 per cent. of the sulphate. D. A. L. Solubility of Lead Sulphate in Aqueous Ammonium Acetate. By J. C. LONG (AmeT. Chem. J., 1899, 22, 217-218).-Lead sulphate is most soluble in a solution of ammonium acetate containing 33 grams per 100 C.C. To dissolve lead sulphate in analysis, it is best to add, for each gram, 10 C.C. of the ammonium acetate solution, heat to boiling, and filter promptly ; t o recover the lead sulphate, 0.5 gram of sulphuric acid should be added, this facilitating the evaporation and expulsion of the ammonium acetate.W. A. D. Separation of Copper and Zinc, By W. DEDERICHS (Chm. Centr., 1899, i, 950; from Pharm. Zeit., 44, 198).-Zinc is estimated in brass by dissolving in the smallest possible amount of nitric acid,ANALYTICAL CHEMISTRY. 813 diluting with water containing 2 -3 per cent. of hydrochloric acid, and removing the copper by means of hydrogen sulphide ; the filtrate is then boiled and the zinc precipitated with sodium carbonate. To estimate copper, the nitric acid solution of the brass is digested with sodium hydrogen sulphite, and an excess of a, standard solution of ammonium thiocyanate is added to precipibate the copper; the excess of the reagent is then titrated with silver nitrate in an aliquot part of the filtrate.Traces of lead are estimated in the usual way as sulphate. L. DE K. Separation of Copper from Cadmium as Oxalate. By G, BORNEYANN (Chem. Zeit., 1899,23, 565-566).-The solution of copper and cadmium, which must not *be too concentrated, is mixed with a moderate quantity of nitric acid, heated to boiling, and then mixed with a slight excess of oxalic acid previously dissolved in boiling water ; the liquid is then placed in a water-bath until it has become quite clear. The precipitated copper oxalate is first washed by decantation with boiling water containing a little nitric and oxalic acids, and then collected on a suitable filter and washed with boiling water containing a t first a few drops of oxalic acid; in this way, the precipitate is obtained free from cadmium. The oxalate is finally converted into sulphide by ignition with sulphur in a current of hydrogen.L. DE K, Modification of Eschka’s Mercury Assay. By K. E. CHISM (Chem. Centi-., 1890, i, 996; from Tmns. Anaer. Inst. Min. Eng., Oct., 1898).--Eschka’s method of mercury assay by collecting the mercury vapour on a weighed golden lid, gives accurate results, but is somewhat expensive, as the gold soon wears out. The author now substitutes a lid made of silver of about 0.02 mm. thickness ; this may be used three times, and costs but little. 0-5-1 gram of the ore is mixed in a porcelain crucible with 5 grams of clean iron filings, another gram of the iron being sprinkled on the top. The crucible is placed on a perforated plate and the lid is put on, and cooled by placing on it a silver or copper basin filled with cold water.The bottom of the crucible is now heated for 15 minutes with a spirit lamp, and when cold the lid is taken off and re-weighed. On applying heat, the mercury volatilises, and the lid may be used again. L, DE K. Volumetric Estimation of Manganese in Manganates by means of an Alkaline Solution of Arsenious Acid. By C. REICHARD (Cliem. Zeit., 1899, 23, 801-S02).-The process is based on the fact that on adding an alkaline solution of ai.senious acid of known strength to a solution of a manganate, t’he latter is reduced to manganous hydroxide. The unoxidised arsenious acid is then esti- mated by standard iodine ; or the manganous hydroxide may be at once redissolved by adding sulphuric acid and the arsenious acid then estimated in acid solution with standard permanganate.Five molecules of arsenious acid used for reduction are equivalent VOL.

By SAMUEL AVERY and BENTON DALES (Ber., 1899, 32, 2233-2238, Compare this ttol., ii, 251, and Verwer and Groll, ibid., 387) -The authors maintain the accuracy of their former conclusion that the ordinary methods for the electrolytic estimation of iron do not yield satisfactory results, because a small amount of iron remains in the solution, and the deposited metal contains carbon. I n the presence of oxalic acid, the reaction with potassium thiocyanate is not delicate, and cannot therefore be depended on for indicating the completion of the deposition.Oxalic acid is converted by electrolytic reduction into glycollic acid, and the presence of this in the solution causes the deposited metal t o contain carbon. A. H. Potassium Ferrocyanide as a Source of Ironin the Volumetric Analysis of Iron. By K. SCHRODER (Chem. Zeit., 1899,23,533-534, 640-541, 557--559).--The author states that potassium ferrocyanide may be obtained almost absolutely pure and be advantageously utilised as a source of pure iron when standardising solutions for the technical estimation of iron. Four or five grams of the pure salt are heated in ft Kjeldahl flask with 20-25 C.C. of strong sulphuric acid ; heat is applied, moderately a t first, and then gradually increased until boiling sets in, which is then kept up for half-an-hour, When cold, 25 C.C.of water and 10-15 C.C. of hydrochloric acid of sp. gr. 1.19 are added and the mixture warmed until completely dissolved. This solution may now be reduced with zinc, or by means of stannous chloride followed by mercuric chloride, and will then be fit for standardising purposes. L. DE K. Estimation of Iron in Organic Matter. By FRANZ ROHMANN and FRANZ STEIKITZ (Zeit. and. Chem., 1899,38, 433--435).-1nstead of destroying the organic matter by incineration, it is far preferable to employ Neumann’s method of heating with concentrated sulphuric acid and ammonium nitrate. The operation is performed in a Jena glass flask over the naked flame, the ammonium nitrate (1 gram for each C.C.of acid) being added in several portions, and the heating continued until a clear, pale yellow liquid is obtained. This is now made alkaline with ammonia and the iron precipitated as sulphide by adding a few drops of colourless ammonium sulphide with the usual precautions. The iron sulphide is collected on an ash-free filter, from which i t is re- dissolved by sulphuric acid, the solution being run back into the precipitation flask, where it dissolves any iron sulphide adhering to the sides. Here it is concentrated by boiling and transferred t o a platinum basin, in which, meanwhile, the filter has been incinerated and its ash fused with potassium hydrogen sulphate. By introducing a rod of zinc for about half-an-hour, the ferric salt is completely reduced, and is then titrated with permanganate.In dealing with fzeces, the large amount of calcium sulphate formed is an inconvenience. It is best not to attempt to remove it from theANALYTICAL CHEMISTRY. 81 5 original acid solution, but to precipitate the iron sulphide in the turbid liquid. Urine (300-400 c.c.) should be mixed with 25-30 C.C. of fuming nitric acid and boiled down to cz small volume before adding sulphuric acid (20-30 c.c.) :tnd aiuinonium nitrate. Iron Separations with Alkali Salts. I. By HARRY BREARLEY (Chem. News, 1899, 79, 193--194).--It is pointed out that for the separation of iron from manganese, zinc, nickel, cobalt, and sometimes copper, alkali acetates, phosphates, sulphates, chromates, tungstates, and molybdates are amongst the available reagents. Separation with acetates has already been investigated (Abstr., 1896, ii, 676 ; 1897, ii, 388; 1898, ii, 96 and 143) ; i t is, however, now shown that it is best not to add the acetate to the cold solution, and then to heat to boiling, but that the acetate should be added to the hot solution.Further- more, it is shown that with a constant quantity of nickel or other metal and varying quantities of iron, the exactness does not necessarily increase with the decrease in the proportion of iron ; but with fixed proportion of iron and a varying proportion of nickel, probably the separation is better for small than for large amounts of nickel. 11. J. S. D. A. L. Detection of Cobalt in the Presence of Ferric Compounds, By HENDRIIZ.WEFERS BETTINIZ. (Chem. Cent?.., 1899, i, 904; from Ned. Tydschr. Pharm., 11, 64-66).-When a solution of cobalt is mixed with potassium thiocyanate, and a mixture of ether and alcohol poured on to the surface, a blue coloration is observed in the upper layer. I n the presence of ferric salts, however, the red colour given by ferric thiocyanate interferes with the test, but in this case the iron compound may be removed by first extracting the mixture with pure ether, which dissolves the ferric thiocyanate but not the cobalt; com- pound ; the ether-alcohol mixture is then added to the residual liquid. The author has improved the method by operating as follows: Potassium thiocyanate is added and the red coloration is destroyed by adding powdered sodium thiosulphate ; the liquid is then covered with a layer of ether-alcohol. 0.001 gram of cobalt nitrate may thus be detected in the presence of 1 gram of ferric chloride, L.DE E. Reduction of Chromic Acid by Acetic Acid and its Effect in Anthracene Testing. By HENRY BASSETT (C'hem. News, 1899, 79, 157).-When the mixture of acetic acid with chromic acid used in anthracene testing is stored, the latter suffers some reduction, a reaction that is still more marked when undiluted acetic acid is boiled with chromic acid; but it also takes place with aqueous solutions of acetic acid when boiled, not, however, when the volumes of the acetic acid and water are equal. The reduction is more marked with acid crystallising at 13.5' than with the purer acid crystallising a t 17".I n anthracene testing, the less pure acetic acid and mixed solutions of acetic and chromic acids that have been kept too long (more than 15 days) will give results which are too high. Testing O i l of Turpentine for Mineral Oils. By C. SCHREIBER and F. ZETZSCRE (Chem. Zed., 1899, 23, 686-687).-The following D, A. L. 55-2816 ABSTRACTS OF CHEMICAL PAPERS. method is suggested as a good preliminary test: 1 C.C. of the sample of turpentine is diluted to 50 C.C. with alcohol of 90-95 per cent. 20 C.C. of this solution are put into a 75 C.C. glass cylinder and 20 C.C. of a solution containing exactly 15 grams of potassium bromate and 50 grams of potassium bromide i n a litre are added, followed by 20 C.C. of dilute sulphuric acid (1 : 3). The stopper is inserted and the mixture well shaken for half a minute.If the liquid should not be quite decolorised, the sample is likely to contain mineral oil and should be submitted to further analysis, but otherwise it may pass as Estimation of Dry Substance in Glycerol. By G. BENZ (Zeit. and Chem., 1899, 38, 436--438).-1t is commonly accepted that glycerol cannot be estimated by drying at looo, because the glycerol begins to volatilise as soon as all the water has evaporated. The author shows, however, that this occurs only in shallow, uncovered vessels. By employing a wide-necked flask covered with a loose glass cap resting on the ueck, glycerol can be dried to a constant weight either a t 100' or 110",and that this takes place without loss is shown by dissolving glycerol, so dried, in water and re-evaporating the solution in the same flask, when exactly the same weight of dry substance will be obtained.M. J. S. Estimation of Glycerol in Fermented Liquids. By J. B. VIN- CENT LABORDE ( C l ~ m . Centr., 1899, i, 905-906,1086; from Ann. chim. nnal. appl., 4, 76-80; 110-114. Compare Abstr., 1896, ii, 77).- The process is based on the fact, noticed by the author, that a t 150-200°, glycerol is quantitatively decomposed by sulphuric acid with liberation of the whole of the carbon; 1 part of carbon represents 2.56 parts of glycerol. A quantity of liquid containing from 0-1-1 -0 gram of glycerol is mixed with 10 drops of sulphuric acid and boiled down in a 250 C.C. flask with small, flat bottom until about 2 C.C. are left, 6 C.C. of sulphuric acid are then added and the flask closed with a rubber cork through which passes a glass tube drawn out to a fine point.The mixture is now heated on a sand-bath to 150", and when the action takes place the temperature rises to 200". After a few minutes, 5 C.C. of dilute hydrochloric acid (1 : 1) are added, and the whole is heated on the sand-bath until white fumes begin to form ; the carbon is now thoroughly washed by decantation with boiling water, and then transferred to a weighed platinum dish; R little ammonia is added, and the whole dried first at 110" and then over a small rose- burner until no more ammoniacal odour is noticed. When cold, the carbon is weighed and allowance made for any ash. To estimate glycerol in saccharine liquids, any sugar must first be removed.If the amount does not exceed 0.5 gram per litre, 50 C.C. are mixed with 100 grams of small shot, evaporated down to 2-3 C.C. and gradually mixed with 1-2 grams of calcium hydroxide ; 75 C.C. of ether-alcohol mixture (2 : 1) are then added to dissolve the glycerol; the liquid is filtered, and theresidue is washed with more of the ether mixture until the filtrate reaches 200 C.C. After adding 10 drops of sulphuric acid, the ether-alcohol is distilled off and the residue treated as already described. commercially pure. L. DE K.ANALYTICAL CHEMISTRY. 817 If the amount of sugar amounts to 5-20 grams per litre, the sufficiently concentrated solution is mixed with 2 grams of calcium hydroxide which has been moistened with alcohol; if the mass does not readily set, a little more dry lime should be added ; the mass must then be extracted as before with ether-alcohol mixture.If the liquid contains more than 20 grams of sugar per litre, a volume of it which will contain about 5-6 grams of sugar is mixed with 2 grams of calcium hydroxide suspended in 10-20 C.C. of proof spirit and then boiled with 100-200 C.C. of 80 per cent. alcohol. When cold, an aliquot portion of the filtrate is acidified with tartaric acid, and the alcohol having been expelled, the residue is treated as before with the ether-alcohol mixture. The test analyses are very satisfactory, L. DE K. Behaviour of Iron Salts with Pyrogallol. By A. HIRSCH (Chem. Centr., 1899, i, 927 ; from Phavm Zeit., 44, 205)-When 2 drops of a solution of ferric chloride containing 10 grams of liq. ferri.sesquichlor., in 90 of water are added to a few C.C. of a 1 per cent. solution of pyrogallol, an amethyst-blue coloration is first formed, which rapidly changes to reddish-brown, but if 1 C.C. of a 0.1 per cent. solution of sodium hydroxide or 0.5 C.C. of a 0.5 per cent. solution of sodium carbonate be then added, the solution becomes deep blue. The brown coloration is restored, however, by adding very small quantities of mineral acids. Zinc oxide or barium carbonate acts like the alkalis, hence the brown coloration must be due to the mineral acid contained in the ferric salt. Organic iron salts give blue colorations, which become brown only on addition of mineral acids. A solution of pyrogallol, rendered reddish-brown by the addition of a very dilute solution of ferric chloride, may be used to test for faint alkalinity, as, for instance, in the case of dilute solutions of alkaloids, which give the blue coloration. When pure ferrous salts are mixed with solutions of pyrogallol, a white turbidity is formed, and if a very dilute solution of sodium hydroxide is then added, the solution becomes blue, probably owing to paGtia1 oxidation of the ferrous salt.E. W. W. Estimation of Mannose in Mixtures of Sugars. By EMILE BOURQUELOT and HENRI HERISSEY (Compt. vend., 1899,129,339-341). -The solution of mannose is mixed with a solution of equal volumes of phenylhydrazine and glacial acetic acid, allowed to remain for 8 hours a t the ordinary temperature, and the precipitate washed success- ively with ice-cold water, alcohol, and ether, and dried in a vacuum.The results are not affected by the presence of galactose, arabinose, maltose, or dextrin, and are accurate if the solution contains 3 to 6 per cent. of mannose, and the operations are conducted a t as low a temperature as possible. A correction should be made by adding 40 milligrams to the weight of the precipitated hydrazone for every 100 C.C. of solution.

B.818 ABSTRACTS OF CHEMICAL PAPERS. are estimated by the phloroglucinol method, the result, calculated as arabinose, may be from 0*60-0*89 per cent.too high if cane sugar is present. Substances yielding furfuraldehyde are found in the diffusion syrup to the extent of only 0.2 part for every 100 parts of cane sugar; the concentrated juice contains 0.13, and the first crop oE crystals 0.03 part; the greater portion of these passes into the “scum” or Cobalt Derivatives of Sucrose and of Dextrose. By W. HERZOG; (Chem. Zeit., 1899, 23, 627-628).-Papasogli (Abstr., 1898, 194) states that an aqueous solution of cane-sugar, when treated with a few drops of il solution of a cobalt salt and then with an excess of sodium hydroxide, gives an amethyst-violet coloration which is moder- ately stable, whereas an aqueous solution of dextrose, when treated in the same manner, yields a blue colour which is remarkably evanescent, changing quickly to a dirty green, and he recommends this reaction as a test for sucrose in the presence of dextrose.The author finds that the colours produced in the two cases are very similar, that with dextrose, however, is not SO stable-it immediately t u r n s blue and then a dirty green; with sacchrtrose, too, the final colour is dirty green. The method is therefore of no use in testing for sucrose in the presence of dextrose. With regard to the nature of the pro- ducts, it is thought probable that they are compounds of the cobalt salts with alkali sucrates or dextrosates, the colour depending to a certain extent on the actual cobaIt salt employed. Analyses of Honey, By c. HOITSEMA (Zeit.ccmccl. Chewb., 1899, 38, 439-441).-1n 10 samples of honey of known origin, the follow- ing estimations have been made : (1) specific gravity a t 15’ of a filtered solution of 1 part of honey in 2 parts of water ; (2) pollen and wax, the constituents insoluble in warm water; (3) moisture estimated by drying without heat in a vacuum desiccator ; (4) polariscopic rotation (after Konig, Unters. Zandw. gew. wicht. Stofe, 1898, 474 ; ( 5 ) ash ; (6) reducing and invertible sugars. The sp. gr. ranged from 1.102 to 1.14, water from 8.3 to 17.8 per cent. ; polarisation from-3.1 to - 9.1, being in all cases negative, ash, 0.12 to 0.34 per cent., pollen and wax, 0.02 to 0.46 per cent. ; reducing sugar, 71.2 to 74.4 ; and sucrose, 0.2 to 2.6 per cent., whilst a sample of unknown origin sh0wed 6.4 per cent.of the latter. By OTTO FOERSTER (elhem. &it,, 1899,23,196).-The analysis is generally made by mixing a weighed quantity of the sample with water UP to a definite volume, and afterwards making a correction for the volume of the undissolved matter; but this process can hardly lay claim t o accuracy. The author recommends weighing out a multiple of 13.024 grams of the fodder and then extractiiig this in LZ Sickel’s apparatus with absolute alcollol ; after 12 honrs, it may be taken for grantecl tohat all the sugar has been extracted. After distilling off the spirit, the residue is dissolved in water and diluted to a volume representing 75 C.C. for each 13.024 grams of the sample, and the sugar is then the molasses. L. DE K. J.J.

The caramel is precipitated from the solution by amylic alcohol, the precipitate redissolved, reprecipitated once or twice more, and finally dried a t 90° and weighed. The caramel may also be determined by titrating with Violette’s or Fehling’s solution, but if dextrose is present it is necessary to titrate the original solution before and after treating with an excess of lead acetate. Then if A=c.c.of copper solution required, c6 = C.C. of original solution required for 5 C.C. of copper solution, the volume of the copper solution corresponding with the caramel is 5(1- a,/A), Allowance must also be made for the amount of lead acetate solution (1/10 vol.) used. The dextrose may also be de- stroyed by boiling with calcium carbonate and then precipitating with carbonic anhydride. Traces of caramel are estimated by treating 200 C.C. of the solution with excess of ammoniacal lead acetate. The prscipi- tate, after washing with water free from carbonic anhydride, is sus- pended in water and decomposed with hydrogen sulphide.The filtrate is again treated with lead acetate, and the solution, from which the hydrogen sulphide has been expelled by evaporating to 10 c.c., is titrated with copper solution. Determinations of the amount of caramel in various sugar products are quoted. E. W. W. Estimation of Glycogen. By EDUARD PFLUGER and JOSEPH ibid., 543-551, Compare this vol., ii, 529).-These two papers con- tain more criticisms of Kulz’s method, and show that it can be improved by certaiu modifications. A new method, which is simpler and gives practically the same results as the improved Kulz method, depends on the fact that in an alkaline solution of glycogen, or extract oE flesh or liver, alcohol will completely precipitate the glycogen, and if the solution contains potassium iodide, the proteid matter remains in solut.ion.W.

By ARTURO SOLDATNI and E. BERT& (Gaxxetta, 1899, 29, i, 489-49’7).-The authors assign the considerable differences found in the results of analyses by different workers of commercial calcium citrate to two causes.Firstly, tho amount of water retained by the sample varies with the method of storage, with the time of exposure t o the air, &c. Secondly, when estimated as calcium citrate, the solubility of the latter in the wash- ing water is not properly allowed for. Error is also sometimescaused by excessive drying of tbe citrate which then becomes t o a alight extent insoluble in acetic acid. The authors find t h a t crystallised calcium citrate loses 2H,O a t 100-130°, and the remaining 3H,O at 175-185’. The following method of analysis is recommended. 1 gram of the finely powdered substance is heated in an Erlenmeyer flask with 10 C.C. of water, about 20 drops of hydrochloric acid of sp. gr. 1-18 added, and when solution has taken place, the liquid is cooled, made distinctly alkaline to phenolphthalein with N/2 sodium hydr- oxide, and then about 3 C.C.of acetic acid added.

Calcium oxalate also becomes quite anhydrons when thus treated. The mixed acids are titrated with standard baryta, and 80 per cent. by volume of alcohol is then slowly added with constant stirring. Barium citrate and oxalate are almost completely precipitated, whilst the malate practically remains in solution, the two errors fairly com- pensating each other.The malate is then recovered from the filtrate Ly adding alcohol until i t s amount reaches 70 per cent. by volume, and leaving the mixture for 24 hours.

It would therefore have been liable to be reported as adult.erated with a considerable amount of margarine. It was made from the milk of three cows fed on the usual mixed diet. By ALEXANDER ZEGA (Cheni. Xeit., 1899, 23, 3lZj.-Butter is melted and filtered, and some of the fat is put into a test-tube and heated for 2 minutes in the boiling water-bath. One C.C. is drawn off with a small pipette previonsly heated and put into a glass-stoppered cylinder containing 20 C.C.of a mixture of 6 parts of ether, 4 parts of alcohol, and 1 part of glacial acetic acid. The cylinder is placed in water at 15-18', when, iE the sample is pure, the liquid remains clear or only deposits an inappreciable amount of fatty matter. With butter containing 10 per cent. or more of margarine, however, a more or less abundant deposit is obtained which may be examined microscopically.

Presence of Chlorinated Organic Compounds and Absence of Sulphur Compounds in Cotton Seed Oil. By P. N. RAIKOW (Chenz. Zeit., 1899, 23, 769-770 and 802).-Although cotton seed oil does not contain sulphur, i t gives the phloroglucinol-vanillin test (this vol., ii, 52); this is due to the presence of chlorinated com- pounds, which, on burning, yield hydrogen chloride. By means of the tubular lamp previously described, the oil was burnt in a beaker placed on its side and the inner surface of the beaker was kept moistened with potassium hydroxide solution.Duponi’s method (Abstr., 1896,,i, 409) has also been employed, but no sulphur could be detected. The chlorinated compound is not extracted by water, but is somewhat volatile in superheated steam. Olive oil and walnut oil, although they give the phloroglncinol reaction, are free from both sulphur and chlorine (compare Fox and Riddick, Chem. News, 1895, 71, 296; also Dupont and Charabot, Bull. SOC. Chin., 1896, [ iii], 15, 341). The presence of chloro-deriva- fives in cotton seed oil may be made use of in determining whether this oil has been employed in adulterating other oils. ‘‘ Vegetale ” (Cotton-Stearin) : Isolation of Cholesterol and Phytosterol from Fats, By F.

Its iodine number is 89.24, and its saponification number 196.1. It gives the Bechi test in a very marked degree, and shows a refraction of 63.3’ a t 25”. By using Bohmer’s process for the isola- tion of cholesterol and phytosterol, the latter may be readily detected, and mixed crystals of both these substances may be obtained from lard adulterated with only 10 per cent. of ‘‘ vegetale.” Bohmer’s process gives satisfactory results even with very rancid fats, and it is only when the samples have been kept for many years under un- favourable conditions that no crystals can be obtained.Kreis’s process for the isolation of cholesterol and phytosterol (this vol., ii, 343) requires 50 grams of fat, whilst Bohmer’s test may be made with 25 grams only, so it possesses no decided advantages.

The most important outcome appears t o be that, in the estimation of urea by the Morner-Sjoquist method, part of the nitrogen of hippuric acid, allantoin, and creatinine is reckoned as urea nitrogen.

By WILHELM KINZEL (Lcmdw. Fersuchs-Xiat., 1899, 52, 169--193).-The method employed was that of Dirck as modified by Schlicht (Abstr., 1892, 1035), except that the substance was steam-distilled, as proposed by Forster (Landw. Yemuchs- Stat., 1898, 50, 419).Powdered rape cake (15 grams) and white mustard (4 grams) are mixed with water (150 c.c.) and tartaric acid (0.25 gram) in a 500 C.C. Erlenmeyer flask. The heatingof the steam flask is so arranged that steam begins to pass over in about half-an- hour ; the Erlenmeyer flask is now heated with a small flame until, in 18 hours, SO0 C.C. has distilled over. The vapours pass through a 0.6 cm. tube, 70 cm. long, into three receivers (an Erlenmeyer flask, a Will-Varrentrapp apparatus, and a second Erlenmeyer flask) con- taining 100, 18, and 10 C.C. respectively of alkaline permanganate solution. As the distillation proceeds, the heating of both flasks must be increased to avoid violent rising of the liquid in the Will-Varren- trapp apparatus. The safety tube of the steam flask is only opened in the case of the permanganate flowing backwards to the flask con- taining the substance.The liquid in the three receivers is mixed, heated for an hour on a water-bath, and after cooling to 70°, treated with alcohol (25 c.c.) and diluted to 501 C.C. Every 3.333 grams of pre- cipitate (KH,Mn,O,,) corresponds with 1.012 C.C. of solution at 17.5". After filtration and addition of a little acid and iodine, the sulphuric acid is determined in the manner described by Schlicht (Zoc. cit.), the result being corrected by adding 0.00319 to the amount of barium sulphate from 400 C.C. The results obtained with n number of samples of different varieties of brassica from India are given. Estimation of Urea. By SERGEI SALASKIN and J.ZALESKI (Zeit. physiol. Chem., 1899, 28, 73--87).-The estimation of urea in urine by the Morner-Sjoquist method gives results which are too high. This is because part of the hippuric acid nitrogen is reckoned as urea nitrogen ; and the more hippuric acid the urine contains the greater the error.

By OTTO LINDE ( A d .Phurna., 1899, 237, 392-408. Compare this vol., ii, 534).-Keller’s method (compare Abstr., 1897, ii, 84) is open to the following objec- tions. (1.) The assumption is made that the solvent either extracts all the alkaloid, or, a t least, contains it in equal concentration throughout, whether within or without the drug ; it is found, however, that the residual part, including the much-swollen drug, contains proportionally more alkaloid. (2.) The amount of solution removed is assumed to contain 100/120 of the alkaloid; as a matter of fact, the total amount of the solution may have suffered an increase owing to the solution in it of fat, and even of soap. (3.) The repeated shaking and the large amount of solvent used are objectionable ; shaking once with a smaller quantity suffices if the volume of the aqueous solution is kept relatively small; it may also be saturated with some salt.(4.) It is better to measure the quantities of solvent used than to weigh them; pipettes graduated for use with water may be employed. Ekroos’ method (this vol., ii, ‘74) cannot be used with drugs from which ammonia or an aliphatic amine is liberated by treatment with soda ; neither can it be used with drugs which contain oil, as in these cases a soap is formed which dissolves in the chloroform-ether, and uses up some of the sulphuric acid. Katz’s method (Abstr., 1898, ii, 547) is equally unavailable for drugs from which soda liberates ammonia or an amine. It is better not to estimate an alkaloid only by titrating its solution, but first to weigh it after evaporation of the solution, in which pro- cess volatile alkalis are removed, and then to titrate the residue; a serious discrepancy between the two results would indicate adulteration.Hydrastine Pentiodide Hydriodide. Volumetric Estimation of Hydrastine and Berberine in the Root of Hydrastis Canadi- ensis. By HARRY MANN GORDIN and ALBERT B. PRESCOTT (Arch.

For the estimation of the alkaloids in Hgdmstis ccznudiensis, 10 grams of the powdered root are stirred into a paste with a mixture of alcohol, concentrated ammonia, and ether (1 : 1 : 6 parts by volume), and allowed to remain in a well-closed vessel for several hours.The mixture is then dried, at first in a good draught and then over sulphuric acid under diminished pressure ; the residue is transferred to a Soxhlet apparatus, being rinsed out with powdered barium nitrate, and the hydrastine is H.

B.ANALYTICAL CHEMISTRY. 827 extracted completely with absolute ether ; the ether is evaporated from the extract, and the residue dissolved in acidified water, and the solu- tion diluted to 100 C.C. I n a graduated 100 C.C. flask, 20-30 C.C. of a standard iodine solution (of about 1 per cent. strength) are placed, 20 c.c, of the filtered hydrastine solution run in, and the mixture diluted to the mark and shaken until the pentiodide has all separated ; the mixture is then filtered, and the excess of iodine determined by titrating 50 C.C.of the filtrate with standard sodium thiosulphate solution. Every 1 part of iodine used corresponds with 0.60403 part of hydrastine. Or the alkaloid may be estimated gravimetrically by shaking 20 C.C. of the filtered hydrastine solution with benzene and ammonia, removing the alkaloid from the benzene solution by shaking with acidified water? and then from the acid solution with ammonia and ether, the ethereal solution is finally evaporated in a dark place at the ordinary temperature, and the residue of hydrastine weighed.The residue in the Soxhlet apparatus contains the berberine, which is not soluble in absolute ether ; it is dried by passing a current of dry air through the apparatus, and is then extracted with alcohol. The alcohol is removed from the extract by heating i t with 200 C.C. of water on the water-bdth; the residual liquid is acidified with acetic acid, cooled, and filtered into a conical flask; in this it is shaken for 10-15 minutes with 6-8 C.C. of acetone and enough 10 per cent. caustic soda solution to render the reaction alkaline, and set aside for 2-3 hours. The precipitated acetone compound is washed, and warmed in the same flask with 200-300 C.C. of very dilute sulphuric acid until i t has all dissolved, the solution is poured into a long-necked Kjeldahl flask and boiled for 14-2 hours; when cold, it is added to 100 C.C.of N/20 potassium iodide solution contained in a graduated 1000 C.C. flask, diluted to the mark, shaken, and left overnight. Then 500 C.C. are filtered from the precipitate of berberine hydriodide into another 1000 C.C. flask, treated with 50 C.C. N/20 silver nitrate and nitric acid, diluted to the mark, and filtered ; the excess of silver is determined by titrating 500 C.C. of the filtrate with N/40 ammonium thiocyanate. The number of C.C. of the iodide solution used, multiplied by 0.16’7125, gives the percentage of berberine in the root. Vitali’s Test for Veratrine. By IWAN L. KONDAKOFF (Clhem. Zeit., 1899,23,4).-The author confirms Kunz-Krause’s statement that when veratrine is evaporated with fuming nitric acid and the residue treated with alcoholic potash, the mixture turns blood-red and evolves a strong odour of coniine.The odorous substance is really coniine, By HANS KREIS ( C l ~ m . &it., 1899, 23, 21--22),-The author warns toxicologists that cholesterol and phytosterol also give reactions with benzaldehyde and sulphuric acid very similar to that described as characteristic for picrotoxin by By GUSTAVE PATEIN (J.

For its estimation, 1OOc.c. of the serum are diluted with 900 C.C. of water, and the liquid is rendered faintly acid with 10 per cent. acetic acid. The mixture is left for 24 hours, and the precipitate washed by decantation with Water slightly acidified with acetic acid. It is then dissolved in 60 C.C. of water previously acidified with acetic acid, 1 to 2 grams of sodium sulphate or chloride are added, and the solution boiled. From this stage, the process is the same as for the estimation of albumin, Estimution of total olbumin.-lO C.C. of the serum are diluted to 100 C.C. with water, the liquid is rendered very faintly acid with acetic acid, and 2 grams of sodium sulphate are added. The mixture is boiled, and the precipitate, collected on a tared filter, washed with boiling water, alcohol, and ether, and dried and weighed, Estimation of serin and serum-globuZin,--The serum previously diluted with 9 times its volume of water, is rendered faintly acid with acetic acid and the mixture left for 24 hours. It is then heated to boiling, and the precipitate collected, dried, and weighed. Estimation of serin.-The serum is diluted with 0 times its volume of water, and 100 C.C. of this solution are saturated with magnesium sulphate. The liquid is filtered, and an aliquot part of the filtrate, faintly acidified with acetic acid, is boiled, and the precipitated serin dried and weighed. The serum-globulin is estimated by difference, 1000 grams of blood serum were found to contain : total proteids, 75.4 ; alkaliseralbumin, 2-45 ; serin and other proteids, 45.03 ; and globulin, 27.92. H. R. LE S. Estimation of Albumin in Urine. By GEORUES DENIGES (S. Pharm., 1899, [ vi], 10, 97--102).--The author’s method for the estimation of casein in milk (Abstr., 1897, ii, 532) is applicable t o the estimation of albumin in urine. For urine containing not more than 1.1 grams of albumin per litre, the method is as follows: 20 C.C. of mercuric potassium iodide and 2 C.C. of glacial acetic acid are added to 150 C.C. of the urine, and the whole diluted to 200 C.C. The mixture is filtered, and 25 C.C. of an ammoniacal solution of potassium cyanide (equivalent to A720 silver nitrate) are added to 125 C.C. of the filtrate, the whole left for 2 or 3 minutes, and again filtered. To 120 C.C. of the last filtrate, N/10 silver nitrate is added until a faint, but permanent, opalescence is produced. The number of tenths of a C.C. of silver nitrate less 48 (a constant) gives the number of decigrams of albumin i5 a litre of urine. If the urine contains more than 1.1 grams of albumin in a litre, then the number of C.C. of urine used must be such that it shall not contain more than 0.15-0*16 gram of albumin, and shall be n simple ratio of 150. If the urine contains less than 0.2 gram of albumin in a litre, the amount is determined by comparing the opalescence produced by the addition of 2 C.C. of a 5 per cent. solution of sodium metaphosphate and 4 drops of sulphuric acid to 10 C.C. of the urine and heating in boiling water for 5 minutes, with that produced, under the same con- ditions, with urine solutions containing a known weight of albumin.

841 Organic Chemistry. Italian Petroleums. By ETTORE CECCHI-MENBARINI (Gaxxettn 1899 28 i 460-470).-Petrolsums from Salsomaggiore and Ozzano in the province of Parma and from Valleia near Piacenza have been examined. The portion distilling between 150' and 270' which is that used for illuminating purposes was separated into fractions with boiling points covering a space of 10'. The density of each fraction and its solubility in a mixture of equal volumes of chloroform and 93 per cent alcohol were measured. The densities of the different fractions show very close agreement with the corresponding values for Russian petroleum but differ greatly from those of American petrol - eum; the same is the case with the curves connecting the density with the solubility in the alcohol-chloroform mixture.The author concludes that Italian petroleum consists of hydrocarbons of the naphthene series. 7'. H. P. Hydration of Acetylene. By MARCELLIN P. E. BERTHELOT (Ann. Chim. Phys. 1899 [vii] 17 297-302).-An account of work already published (this vol. i 264 and 397). Silver Derivatives of Acetylene. By MARCELLIN P. E. BERTHELOT and MARCEL DELEPINE (Compt. rend. 1899,129 361-37s). -The formation of disilver-acetylene by the action of acetylene on ammoniacal silver nitrate develops + 15.55 Cal. and hence C + Ag = C,Ag pptd. develops - 87.15 Cal. When dried in a i r at the ordinary temperature the precipitate contains 89.6 per cent. of silver which agrees with the formula C,Ag and hence i t is neither an oxide nor n hydroxide. The action of acetylene on silver oxide would develop + 22.25 (H,O gas) or + 32-95 Gal.(H,O sol.). When heated in a vacuum disilver-acetylene detonates with a strident noise and a reddish flame carbon being deposited on all parts of the tube. The production of flame is due to the high temperature (about 4000') of the decomposition causing volatilisation of the carbon the condensa- tion of which in i t s turn develops a large quantity of heat. The compound is decomposed by gaseous hydrogen chloride and dilute hydrochloric acid with liberation of acetylene rind development of + 43.25 Cal. and + S.4 Cal. respectively but is not attacked by dilute sulphuric or nitric acid because such reactions would be markedly endothermic. The direct formation of disilver-acetylene would absorb a much larger quantity of heat than the formation of acetylene itself.Chemical analogies indicate the possible existence of a compound C,HAg but thermochemical analogies indicate that i t would be extremely unstable. The substitution of sodium for hydrogen in gaseous hydracids and in acetylene is always exothermic whereas in the case of silver the reaction is endothermic with hydrogen fluoride hydrogen cyanide and nitric acid and especially so with acetylene ( - 29.05 Cal.). Disilver-acetylene is not however decomposed by G. T. M. Gaseous nitric acid however oxidises it violently. VOL.

The re- action C,H gas + 3AgN0 diss. = C2Ag,N03 pptd. + 2HN0 diss. develops + 32.4 Cal. or if the acetylene is dissolved + 27.1 Cal. which gives +5*3 Cal. for the heat of dissolution of acetylene and this agrees with Villard's determination. = C,Ag,NO (3 + Ag + N + 0 C,Ag + AgNO diss. = C,Ag,NO pptd. + 9.85 The nitrate is decomposed by hydrochloric acid and also by ammonia. C,Ag,NO + 3HCl diss. = 3AgC1+ HNO diss. + C,H gas develops +24-44 Cal. C,Ag,NO + 2NH diss. = C,Ag + NH,(NH,Ag)NO diss. develops +3.6 Cal. The nitrate is oxidised by strong nitric acid with liberation of nitrogen oxides and formation of some silver cyanide.The action of acetylene on silver sulphate solution yields the com- pound C,Ag,,AgSO when the silver salt is in excess and the compound (C,Ag,),SO + C,Ag,,AgSO when the action of the gas is continued. The latter salt is insoluble and hence the final compound (C,Ag,),SO described by Plimpton is only formed when the precipitate remains for a long time in contact with the acetylene solution. C,H diss. + BAgSO diss. = C,Ag,,AgSO pptd. + H2S0,diss. develops + 21.2 Cal. C + Ag + S + 0 = C,Ag,,AgS04 develops + 83.3 Gal.

Silver chloride dissolved in ammonia yields three products according t o the relative proportions of silver salt and acetylene and the time of action namely C,Ag,Cl CqAg,C1,C,Ag or C,Ag,(C,A g,)C1 and C2Ag,C1,2C,Ag the first being yellowish the second lemon-yellow and the third deep yellow. The decomposition of the first by hydro- chloric acid develops + 11.8 Cal. and of the second + 33.3 Cal. whilst the heats of formation from the elements are -56.4 Cal.and - 141.5 Gal. respectively. The combination of silver chloride with 1 mol. of disilver-acetylene develops + 1.75 Cal. and with 2 mols. + 3.8 Gal. It is noteworthy that the heats of formation of the compounds C2Ag,C1 and C,Ag,NO are practically identical like the heats of forrna- tion of silver nitrate and chloride. Silver iodide dissolved in potassium iodide solution containing aORGANIC CHEMISTRY. 843 small quantity of potassium hydroxide which is renewed from time to time as the action of the acetylene is continued yields the compound C,Ag,I AgI which is decomposed by hydrochloric acid with development of + 12.65 Gal. ; its heat of formation from its elements is -57.85 Gal. and from C2Ag2+2AgI +Om90 Gal. The compound C,Ag,l is obtained by the carefully regulated action of potassium iodide on the corresponding nitrate ; it is decomposed by hydrochloric acid with development of + 13.85 Cal.and its heat of formation from its elements is - ‘73.2 Cal. When heated the sulphate chloride and iodide detonate somewhat feebly and the nitrate violently. The authors regard the metallic derivatives of acetylene as analogous to the nitrides derived from ammonia and the compound C,Ag as analogous to ammonium NH,. By HANS ALEXANDER (Bea. 1899 32 2351-2384. Compare this vol. Erdmann and Kothner i 21 ; Sabatier and Senderens i 555).-M7hen pure dry acetylene is passed over spongy copper contained in a tube heated at 2,40-250° the metal appears to swell enormously and finally forms a uniform cork-like mass ; when the amount of copper in the product has fallen to 2 per cent. further action ceases.The product when freed from liquid hydrocarbons by warmth or exposure to air is odourless. It decomposes and becomes luminous when strongly heated in air giving off vapours having a peaty odour. By treatment with hydrochloric acid containing ferric chloride it loses the whole of its copper but afterwards contains about 0.2 per cent. of iron; the substance in this case is somewhat lighter in colour but otherwise is similar in appearance to the specimens containing copper. Analysis of the material gave an amount of carbon equal to 85-89 per cent. The gas which passes out from the tube during the above experi- ment is completely absorbed by ammoniacal cuprous chloride yielding the characteristic copper acetylide.The formula C,,H6,Cu has been ascribed by Erdmann and Kothner (Zoc. c k ) to a product obtained by heating copper in acetylene at 230° and they supposed it to be a copper-acetylene compound. The author having repeated the experiment of these workers concludes that the copper in their product was retained mechanically. It is believed that the influence of the copper partakes of the nature of a contact phenomenon and that the action consists in the polymerisation of the acetylene and results also in the formation of naphthene-like hydrocarbons; the hydrogen liberated in the production of these substances is not set free but would seem to be absorbed either by the resulting hydrocarbon or by the cork-like material. C. H:B. Action of Acetylene on Copper.A. L. Boiling Points of Compounds of the General Formula CH,. (CH,),. R.

For the value n = 0 in the general formula that is for the first member of each series the relation does not hold good. Tables are given showing the experimental and calculated numbers for the normal monochloro- monobromo- and moniodo-paraffins amines nitro-paraffins ketones alkylic formates acetates propionates butyrates valerates hexoates heptoates and octoates and for alkyl-ethyl alkyl-propyl alkyl-butyl alkyl-heptyl alkyl-phenyl alkyl-orthotolyl alkyl-paratolyl and alkyl-metatolyl ethers. The agreement for all these series is good the greatest divergences being with the amines nitro-derivatives and ketones where the differences between the calculated and observed temperatures are sometimes as much as 3 or 4'.For the alkylic chlorides bromides and iodides the formula.? are respectively T= 38.66 JX- 10 T= 38.98 J J M - 45 and T'= 39.1 J J M - 78 ; it is noticeable that the three values of c namely - 10 - 45 and - 78 stand very nearly in arithmetical progression.T. H. P. Action of Nitric Acid on Saturated Hydrocarbons. VI. Nitration in Sealed Tubes and in Open Vessels. Separation of Mono- from Dinitro-compounds. By MICHAEL I. KONOWALOFF (Chem. Centp. 1899 i 1063-1064; from J . Idzcss. Chem. Soc. 1899 31 57-69).-When hydrocarbons are heated with nitric acid in closed tubes the yield of nitro-compounds obtained is dependent on the sp. gr. of the acid and the temperature at which the mixture is heated. The acid usually employed has a sp. gr. 1*076-1*2 and the temperature varies from 100-1 30'. Ethylbenzene and diphenyl- methane which are easily nitrated by heating in tubes a t looo are also readily attacked in open vessels by acid of sp. gr. 1.075 and both these methods yield the same products in the case of heptane octane or di-isobutyl.The normal hydrocarbons form mainly secondary nitro-compounds and the iso-hydrocarbons containing the CH-group yield tertiary nitro-compounds ; small quantities of primary nitro- compounds are also produced. Dinitro-compounds are also formed under the same conditions as mononitro-compounds the yields being increased however by employing stronger acid raising the tempera- ture and heating the mixture for a longer time. The dinitro-com- pounds may also be prepared by the action of nitric acid on the mono- nitro-compounds. These two classes of compounds may be separated by (1) fractionally distilling a vacuum being used in the final distilla- tion (2) distilling off the mononitro-compounds in steam or ( 3 ) by means of organic solvents.Dinitro-octane which boils at 170-1 90" under 16 mm. pressure may be separated from the mononitro-corn- pound by the first method. Electrolytic Reduction of Aliphatic Nitro-derivatives. By PAUL PIERRON (Bull. Xoc. Chim. 1899 [iii] 21 780-785).-The nitro-derivative is dissolved in a mixture of ethylic alcohol and dilute sulphuric acid and submitted to electrolysis in contact with a nickel cathode the liquid being separated from the platinum anode by a porous pot containing dilute sulphuric acid. A cathodic current E. W. W.ORGANIC CHEMISTRY. 845 density of 0.4-0.75 ampkre per square decimetre is employed. If the operation is carried out at a temperature not exceeding 15-20' the corresponding P-alkyl hydroxylamine is produced to the extent of 65-80 per cent.of the theoretical quantity whilst at 70" further reduction occurs and a scarcely inferior yield of the amine is obtained. When concentrated hydrochloric or sulphuric acid is employed small quantities of aldehyde and hydroxylamine besides other products are obtained in place of the alkylhydroxylamine; the study of this reaction is being continued. Full details are given in the paper of the application of the methods described to nitromethane nitroethane and nitropropane. N. L. Action of Nitric Anhydride and Peroxide on Olefines. By NICOLAUS I. DEMJANOFF (Chew. Centv. 1899 i 1064; from Ann. Inst. Bgron. Moscow 4 155-2 1 ?').-Ethylene nitrosite C,H,,N,O pre- pared by passing nitric peroxide and ethylene through ether separates in lustrous pseudomonoclinic needles melts and decomposes a t 116-117" is very slightly soluble in organic solvents insoluble in water and when reduced with tin and hydrochloric acid forms ethylenediamine.By the action of nitric anhydride on ethylene at a low temperature ethylenic nitrate is formed ; it boils at 114-116' and explodes on distillation. Since the crude product when reduced yields acetaldehyde ethylenediamine and P-aminoethylic alcohol It is assumed to be the compound NO,* O*CH,*CH,* 0 *NO,. Amylenenitvos- ate NO,* O*CMe,*CMe:NOH obtained by the action of nitric anhy- dride on trimethylethylene melts a t 97". Analyses of the platinum salts prepared from the mother liquor indicated the presence of the compounds OH* C,H,,* NH2 (1) and (OH* C,H,,),NH ( P ) . By the action of nitric anhydride on tetramethylethylene the compounds C,HpO4N C,H,,O,N and C,H,,O,N are formed according t o the conditions of the experiment whilst by the action of nitric peroxide only the two former compounds are obtained.The first compound separates in pseudomonoclinic crystals and sublimes a t 170-1 80". Sincethe corresponding amine NH,* CMe,- CMe,* OH may be prepared by a trustworthy synthetical method this compound must have the composition NO*CMe,* CMe,* 0-NO,. The amine forms pseudomono- clinic crystals melts at lo" and boils a t 160-161° under 254 mm. pressure. The compound NO,*CMe,*CMe,*O*NO separates in crystals which are unlike those of either of the other compounds and melts at 88-89". The third compound NO,* O*CMe,* CMe,. O*NO is also obtained by the action of nitric anhydride on tetramethylethylenic oxide and when reduced with zinc dust and acetic acid yields pinacone hydrate whilst by the action of tin and hydrochloric acid pinacoline and ammonia are formed; it combines with hydrogen bromide t o form tetramethylethylenic bromide C,H1,Br2.The cornpound (C,H80,N2) prepared by the action of nitric anhydride on dimethylethylene crystallises in colourless pseudomonoclinic prisms melts at 133-1 34" and is insoluble in water. By varying the conditions of the experi- ment a product may be obtained which when reduced with t i n and hydrochloric acid yields methyl ethyl ketone and a cornpound OH*CHMe*COMe which distils over whilst the residue contains846 ABSTRACTS OF CHEMICAL PAPERS tetramethyZpzyaxi~e fiMe*y gMe a compound also formed by reducing CMe-N CMe' the product of the action of nitric peroxide on dimethylethylene; i t melts a t 86' and boils a t 189-190'.By MARCELLIN P. E. BERTHELOT (Ann. Chim. Phys. 1899 17 [ vii] 458-4'70).-Potassium silver cyanide is com- pletely decomposed by nitric acid (1 mol. in 2 litres) ; the reaction (AgCN,KCN diss. + HNO dil. = AgCN + KNO diss. + HCN diss.) de- velops 4.2 cal.; an excess of the acid has no further action on silver cyanide. Hydrochloric acid also precipitates silver cyanide from the double salt but if the acid is in excess the precipitate consists of a mixture of silver chloride and cyanide ; this is explained by the fact that the heats of neutralisation of hydrochloric and hydrocyanic acids by silver oxide are 20.6 Cal.and 21.4 Cal. respectively. The double cyanide is more stable towards feebler acids such as acetic boric arsenious and carbonic acids and behaves like a salt of hydrargentocyanic acid. Carbonic acid has no action on the double salt although it reacts with potassium cyanide; in the other cases the heat effect indicates that the decomposition is only partial. The addition of boric acid produces a slight turbidity and the heat developed is 0.12 Cal.; a similar result is obtained with arsenious acid. The addition of iC,H,O C2H402 or l$C,H,O to a solution of KCN,AgCN develops 1.4 2.2 o r 2.6 Gal. respectively these thermal effects being accompanied by the partial precipitation of silver cyanide and the liberation of hydrogen cyanide. The quantity of precipitate increases when the reaction is performed in open vessels.The calcu- lated heat effect for complete decomposition is 3.8 Cal. ; the values obtained from experiment all fall short of this and it is assumed that the discrepancy is due to the formation of hydrargentocyanic acid ; if this substance were quite stable there would be no appreciable thermal effect on the addition of the acetic acid ; the heat developed is due to its partial dissociation into silver cyanide and hydrogen cyanide. I n an open vessel this dissociation continues owing to the escape of the hydrogen cyanide; this accounts for the gradual in- crease of the precipitate. The heat of formation of the hypothetical acid is -3.8 Cal. ; its metallic salts form a well-defined series but there is no thermochemicnl evidence t o show that its silver salt Ag(hgCy,) differs from ordinary silver cyanide.Potassium mercuric cyanide is completely decomposed by bydro- chloric and acetic acids into mercuric cyanide hydrogen cyanide and the potassium salt of the reacting acid; with boric acid the decom- position is very nearly complete. E. W. W. Double Cyanides. 2KCN,Hg(CN) diss. + 2HC1 dil. - 8.0 Cal. 2KCN,Hg(CN) diss. + 2C2H,0 dil. = 8.6 Cal. 2KCN,Hg(CN) diss. + 2B20 and B20 = 3.2 and 0-7 Gal. the calculated values for complete decomposition by boric acid being 3.8 Cal. for 2B20 and 0.9 Gal. for B,03 These results indicate that the hypothetical hydromercuricyanic acid is even more unstable than the corresponding silver compound ; its calculated' heat of formationORGANIC CHEMISTRY.847 is - 8-2 Cal. The mercuric salt of this hypothetical acid is identical with ordinary mercuric cyanide. Potassium zinc cyanide is completely decomposed by hydrochloric acid ; the reaction 2KCN,Zn(CN) diss. (1 mol. i n 4 litres) + 4HC1 (1 mol. in 2 litres) = ZnCl diss. + 2KC1 diss. + 4HCN diss. develops 17.1 Cal. a t 12'. The decomposition by acetic acid is almost com- plete ; a t 12' the reaction is accompanied by an evolution of 11 *8 Cal. the calculated value for complete decomposition being 1 2 Cal. The double zinc salt behaves differently towards hydrogen sulyhide and carbonic and boric acids ; these substances produce no immediate precipitation; the heat developed by the addition of boric acid is 1.7 Cal. the calculated value for complete decomposition being 8.4 Cal.These results indicate the probable existence of a hydrozincocyanic acid H2ZnCy4 intermediate in stability between the corresponding silver and mercuric compounds; the zinc salt of this acid is however identical with ordinary zinc cyanide. Flash Points of Organic Compounds By P. N. RAIKOW (Chem. Zed. 1899 23 145-147).-The flash points of numerous organic compounds lie below their melting points for example benz- ene which melts a t + 6' flashes at - 8'. The determination of the flash point is suggested as a method for testing the purity of certain organic compounds. The flash points of aqueous solutions of ethylic alcohol of various concentrations have been determined by the aid of the usual Abel apparatus ; some of the numbers obtained are as follows Volume per cent.of ethylic alcohol ... 100 90 70 50 30 15 10 4 Flash point ... ... 12' 16.5' 21' 24' 29.5' 41.75' 49' 68' Although the flash point rises with the diIution of the alcohol the increment is not proportional t o the dilution. The maximum contraction in volume is obtained when 51.9 vols. of alcohol are mixed with 48.1 vols. of water and as there is no sharp break in the flash point with an alcohol of this concentration the author argues against the idea of the presence of a definite hydrate in such a mixture. By H. COPAUX (Bull. ~EOC. Chirn. 1899 [iii] 21 776-778).-When boric anhg- dride is heated with alcohol at 125' in an autoclave for 3 hours and excess of alcohol and triethylic borate removed from the product by dis- tillation a syrupy liquid is obtained which according to Schiff (Anmderz Suppl.5 153) is ethylic metaborate BO(OEt) produced by the action of boric anhydride on the triethylic borate first formed. The results obtained by analysis agree fairly well with this supposition but the author considers the substance to be a mixture of polymolecular com- pounds since (1) i t is non-volatile and begins to decomposs a t l$Oo yielding triethylic borate and a viscous residue ; (2) contradictory results are obtained by cryoscopic and ebullioscopic molecular weight determinations whereas triethylic borate is distinctly shown to be unimolecular ; (3) the reaction assumed by Schiff between boric G.

G. T. 31. Influence of Water on the Velocity of Ether Formation. By CORNELIS A. LOBRY DE BRUYN and ALPHONSE STEGER (Rec. Traw. C'him. 1899 18 31 1-325).-A study of the reactions NaOEt + Me1 and NaOEt + EtI in ethylic alcohol shows that the velocity coefficient decreases as the dilution of the alcohol increases whilst in the case of the reactions NaOMe + Me1 and NaOMe + EtI in methylic alcohol the addition of water a t first produces a n increase in t h e value of t h e coefficient which after athining a maximum diminishes continuously :LS the dilution is increased.Owing t o the solubility of rnethyliu iodide in water i t is poshible t o make experiments under all conditions of dilution from absolute alcohol t o pure water; with the ethylic iodide i t is not possible t o employ a medium containing less than 40 per cent. of the alcohol. The velocity coefficient is calculated from determinations of the nllinlinity of the solutions after given intervals of time tho tempemture being niaintained at 25". 'I'he results are tnhulated and the vmiations of the velocity coefficient with change of dilution are represented graphically.It is noticed that when the850 ABSTRACTS OF CHEMICAL PAPERS. dilution is considerable the value of this coefficient for a given dilution is not constant ; as the reaction proceeds a gradual diminu- tion becomes apparent ; this may be due to the change in the concen- tration of the ions the dissociation of NaOEt or NaOMe being different from that of NaI. The velocity of the reaction NaOEt + Me1 in absolute ethylic alcohol is six times as great as that of NaOMet-Me1 in absolute methylic alcohol although the reagents are far more dissociated in the latter solvent ; moreover the velocity of the reaction NaOEt + Me1 in ethylic alcohol is 30 times greater than that of the reaction NaOMe + EtI in rnethylic alcohol.It appears therefore that the velocity of reactions occurring in media other than water depends not only on electrolytic dissociation but also on other undetermined factors.

Chim. 1899,18 309-310).-Amorphous lead hydroxide is precipitated on adding caustic potash to a solution of basic lead acetate; when dried at ordinary temperatures it forms a white powder which is more active than lead oxide in promoting the condensation of formaldehyde to formose. A dilute solution of the aldehyde is heated with a small quantity of the hydroxide for one hour a t looo and evaporated down to a syrupy consistence; the residue is dissolved in a mixture of methylic and ethylic alcohols and treated with ether to precipitate the lead salts of any organic acids present ; the filtrate now contains formose the yield being about '70 per cent.of tbe formaldehyde employed. Lead hydroxide when pre- cipitated by ammonia appears to be crystalline and has no action on formaldehyde ; negative results were also obtained with sodium potassium zinc copper or cadmium hydroxides whilst 10 per cent. of formose was obtained by the use of calcium hydroxide.

W. Combination of Colloidal with Crystalloidal Substances. By A. FRIEDENTHAL (Clbem. Centr. 1899 i 1161-1162; from Cent?..

The freez- ing point of a solution of iodine in potassium iodide however is considerably lowered by adding large quantities of soluble starch. The varying results obtained by the author and by Kiister indicate t,hat this method is not applicable in the case of starch just as physico- chemical methods give untrustworthy results with compounds of such Iiigh molecular weight as albumin and albumoses since the least cluantity of ash causes great errors.By ZDENKO H.

It has been found t h a t if low temperatures and small quantities of sulphuric acid are used the products are more complicated than when these precautions are not observed. [With HUGO HAMBURGER.] -Starch on moderated acetylation gives a n acetyl compound which when hydrolysed with alkalis yields a product having all the characteristic properties of soluble starch. On energetic acetylation however breaking down occurs attended by addition of acetic anhydride and besides amorphous products pentacetylglucose melting at 113’ is obtained ; this however is only produced when the product is treated with water.[With P ~ ~ ~ ~ . ] - C e l l u l o s e when energetically acetylated yields by addition of acetic anhydride a substance which crystallises from ethylic acetate or alcohol i n beautiful long needles melting at 228O and is identical with Franchimont’a substance ; determination of the molecular weight. of the compound however shows that his view of its constitution is incorrect and that i t is either a pentacetylhexosc or a heptacetylheptose. On hydrolysis with alkali it does not yield glucose but a substance sparingly soluble in alcohol although readily soluble in water which gives not an osazone but a phenylhydrazone melting at 194” and closely resembling mannosephenylhydrazone in many particulars.By very careful acetylation cellulose and starch yield derivatives which contain more acetyl than might be anticipated on the basis of the usual formulae for these substances. Cellulose. By G. BUMCKE and RICHARD WOLFFENSTEIN (Ber. 1899 32 2193 -2507).-The so-called oxycellulose obtained by treat- E. W. W. Cellulose and Starch. A. L.ORGANIC CHEMISTRY. 853 ing cellulose with hydyogen peroxide,. possesses many of the propertieh usually associated with aldehydes ; I t is strongly reducing combines with phenylhydrazine and restores the colour to a solution of magenta and sulphurous acid.Cellulose itself is destitute of these properties and the fact that oxycellulose behaves like a reducing agent tells against the view that the action is one of oxidation; here as in the case of cane sugar (Wurster Centr. Physiol. 1 33) hydrogen peroxide acts as a hydrolytic agent. Ash-free filter paper was treated a t ordinary temperatures with varying quantities of re-distilled hydrogen peroxide (4 to 60 per cent.) until the fibres were completely disintegrated. Analyses of the dried product gave numbers cor- responding with 6C,H,,05,H20 7C,H,o05,H,0 or 8C,H,,0,,H20 ; the analytical results are not conclusive owing to the molecular com- plexity of the substances involved. This product the authors call hydralcellulose ; it has no action on iodine solution but when treated with excess of phenylhydrazine i t yields a hydrazone containing 1.69 to 1.S3 per cent.of nitrogen a phenylbydrazone having the composition C,~H,,O,,:N,HPh should contain 3.6 per cent. Cellulose itself is not acted on by phenylhydrazine. The hydrazone partly dissolves in caustic soda solution but the soluble and insoluble portions alike contain the same percentage of nitrogen. When tested with Fehling solution the reducing power of hydralcellulose is found to be 1112th that of dextrose. On acidifying the solution of hydral- cellulose in this reagent a flocculent white precipitate is obtained ; this product ‘6acid-ceZZulose,” is also produced by warming hydralcellulose with excess of 10 per cent. caustic soda solution; the yield is about 33 per cent.an insoluble substance having the properties of cellulose being formed a t the same time; the reaction appears to be quite analogous to the action of alkalis on certain aldehydes ; hydralcellulose (aldehyde) = cellulose (alcohol) + acid-cellulose (acid). Acid-cellulose may also be prepared directly from cellulose either by heating this substance with a 30 per cent. solution of caustic soda until the whole has passed into solution or by acidifying the solution of cellulose in Schweitzer’s reagent ; in the former process the yield is 39 per cent. in the latter the substance is accompanied by a small amount of hydral- cellulose. Acid-cellulose readily dissolves in dilute alkalis but not in aqueous ammonia; it has an acid reaction decolorising an alkaline solution of phenolphthalein and does not react with Fehling’s solution phenylhydrazine or iodine solution ; when left in contact with con- centrated hydrochloric acid it undergoes hydrolytic decomposition into soluble products which have reducing properties.When dried at 1054 acid-cellulose loses water and becomes converted into acid- celluloselactone C,,H,,O ; this substance forms a hard horny mass insoluble in alkalis. The action of concentrated nitric acid on cellulose is not simply one of nitration hydrolytic changes are simultaneously produced so that the same products are obtained by nitrating cellulose hydralcellulose and acid-celluloselactone. The dried substance was in each case mixed with 10 parts of nitric acid of sp.gr. 1.48 and heated for Some time at 85O; the product was soluble in acetone and was separated854 ABSTRACTS OF CHEMICAL PAPERS. into two fractions differing in solubility in ethylic alcohol. The more soluble substance forms a friable mass whilst the other is obtained in coherent films. Both substances derived either from cellulose hydralcellulose or acid-cellulose prepared by Schweitzer’s reagent have the same composition and gave analytical numbers agreeing with the formula {$C72Hl,,6044( N0,)l,,~C72Hl,,0,0(N03)12) ; the more soluble nitro-derivative obtained from the acid-celluloselactone prepared with cellulose and caustic soda solution also had this composition but the less soluble substance contained more of the dinitro-com- pound.The more soluble substance was further identified by deter- mining its rotatory power in acetone solution and its expIoding point. The molecular weight determined in acetone solution by the ebullioscopic method showed t h a t the molecular complexity of the nitro-compound whether obtained from cellulose hydralcellulose or acid-celluloselac tone is the same namely 1350. The experimental results indicate that the formula for hydralcellulose is probably 6C6Hl,0,,H,0 and if the foregoing explanation of its formation from cellulose be accepted the latter substance should have the formula C72H120060. G. T. M. Oxycellulose. By 0. VON FABER and BERNHARD TOLLENS (Bey. 1899 32 2589-2601).-The oxycelluloses obtained from cellulose by the action of various oxidising agents appear to con- sist of varying proportions of unaltered cellulose and a substance C~H1006 or C ~ H ~ O G containing a n additional oxygen atom for which the name cellaxin is proposed.This compound has not been isolated but on heating oxycellulose wibh lime water i t is decomposed into a mixture of isosaccharinic and dihydroxybutyric acids whilst the cellulose remains unaltered. Pine-wood sawdust when heated with moderately concentrated nitric acid for 6 hours yields a white powder having a composition correspond- ing with either the formula C18H,p,O,G or Cl,H3001G ; when the action is stopped after 3 hours the composition of the powder obtained agrees with C24H,s021 or C2,H400,1. On distilling with hydrochloric acid these substances yield about 7 per cent.of furfuraldehyde. The product obtained by treating cotton wool with bromine and calcium carbonate forms a white powder which reduces Fehling’s solution develops a violet coloration with iodine and zinc chloride restores the coloiir to magenta decolorised by sulphurous acid and is insoluble in dilute alkalis or ammonia ; it corresponds in composition with the formula C,,H2,O1 (C,H,,O + C,Hl,06) and on distillation with hydrochloric acid yields about 1.6 per cent. of furfuraldehyde. The composition of the white powder obtained by heating cotton wool with nitric acid of sp. gr. 1.3 for 24 hours on the water-bath corresponds either with C30H4s02G or C30H,,026 ; when the action is continued for 4 hours the composition of the product agrees with either C2,H3,02 or C24H400,,.In the first case the product appears t o contain 4 mols. of cellulose t o 1 mol. of celloxin and in the second case the proportions are 3 1. The oxy- celluloses prepared by the action of nitric acid dissolve in dilute alkalis or ammonia to form viscid solutions having reducing properties and differ in this respect from that obtained by the aid of bromine and calcium carbonate ; all these substances when warmed with causticORGANIC CHEMISTRY. 555 soda give golden-yellow solutions which reduce Eehling's solution. AS the proportion of celloxin becomes greater the solubility in dilute alkalis and the reducing power increase (compare preceding abstract). All the oxycelluloses obtained by the methods described above when boiled with milk of Lime undergo decomposition the celloxin being converted into the calcium salts of isosaccharinic and dihydroxybutyric acids whilst the cellulose remains undissolved.The former acid is isolated by means of its calcium salt which on treatment with acids yields iso- saccharin melting a t 92-94' but having a specific rotatory power of 49.4' (not 62-63" as usually stated). Dihydroxybutyric acid when liberated from a solution of the calcium salt by oxatic acid has at first a specific rotatory power of - 2.6' which after 2 days becomes + 13.7'. In preparing oxycelluloses by the action of nitric acid on cotton wool saccharic acid and other acids containing 4 or 5 atoms of oxygen are produced as bye-products. G. T. M.

The same reaction takes place in 2-3 minutes at 100'. The amines obtained from these products however when treated with methylic bromide yield compounds containing less bromine than that required for dimethylamine hydrobromide &c. and from the products of the original reaction ammonium chloride bromide or iodide respec- tively may be separated by fractionally crystallising from alcohol ; the amounts of tetramethylammonium compounds are estimated by titrating the alcoholic solutions with alcoholic sodium hydroxide solution.

The isomerism of the thioaldehydes is of a kind i n which the isomerides have the same molecular weight and chemical structure but different amounts of energy.For such isomerism the author would prefer the name dynarnicaz isomevisrn were that not already appro- priated; as it is he proposes the term alloergaticc. Malic and fumaric acids form the classical example of this kind of isomerism Liquid thioacetaldehyde which is formed when hydrogen sulphide is continuously passed into aqueous aldehyde has the composition 8 CH,*CHS,H,S. With alkalis i t reacts like a hydrosulphide ; by strong sulphuric acid and other reagents it is converted into a- or P-trithioacetaldehyde ; when distilled it yields ethylic bisulphide along with hydrogen sulphide and volatile sulphides and hydrosulphides whilst a carbonaceous residue remains in the flask.

Molecular Aggregation of Dihydroxyacetone. By GABRIEL BERTRAND (Compt. rend. 1899 129 341-344).-Dihydroxyacetone obtained by the action of the sorbose bacterium on glycerol (Abstr. 1898 i 556) crystallises from its aqueous solution in a vacuum in small prisms which remain unchanged in closed vessels but liquefy after some time if exposed to the air. The crystals are insoIuble in cold absolute alcohol ether or acetone but dissolve in any proportion in the boiling liquids and do not separate when the solution is cooled.The crystals melt slowly a t about '70" and remain in superfusion for a considerable time ; the superfused and therefore amorphous mass dissolves immediately in cold absolute alcohol acetone or ether. Cryoscopic determinations show that when the crystals are dissolved in water at 5' the molecular weight of the substance gradually changes from about 162 to 91. If however the superfused substance is dis- solved its molecular weight in solution is but little higher than 90. The molecular weight of the dissolved substance is higher the lower the temperature. If the solution is heated to 100' and then rapidly cooled the molecular weight is 88-89 but gradually increases to 91-93 if it is allowed to remain at the ordinary tempera- ture.These facts indicate that i n crystallised dihydroxyacetone two molecules of the simple substance are aggregated together and that these are more or less completely separated when it is dissolved or fused.

The colour changes to various shades of violet and blue the strongest acids producing the bluest shades. I n this way differ- ences may be observed between acetic and formic glycollic lactic and propionic acids ; also between succinic and maleic and dibromo- succinic acids. The increase in strength resulting from the successive addition of chlorine may be shown in the case of acetic acid and its chloro-derivatives ; the increase due to the substitution of hydrogen by hydroxyl is indicated by succinic malic and tartaric acids whilst a gradual decrease of acidity is observed with the following series oxalic malonic and succinic acids.By ALEXIUS ALBITZKY (Chem.

J. S. Isomerism of Oleic and Elaidic Acids and of Erucic and Brassidic Acids. By ALEXIUS ALBITZKY (Chem. Cent?.. 1899 i 1068-1070 ; from J. Russ. Chem. Xoc. 1899 31 76-loo).- Chlorohydroxystearic acids were prepared from oleic iso-oleic and elaidic acids and chlorohydroxybehenic acids from erucic iso-erucic and brassidic acids by means of the additive compounds formed with hypochlorous acid. In most cases it was impossible to obtain a pure product and the partially purified compound was used in the follow- ing reactions. By the action of aqueous or alcoholic potash on the chlorohydroxystearic acid prepared from elaidic acid the dihydroxy- stearic acid melting a t 136.5' is formed. This acid is also obtained by oxidising oleic acid with potassium permanganate (A.Saytzeff) whilst elaidic acid on oxidation by permanganate yields the dihydroxj- stearic acid melting at 99-100'. The latter acid is also formed by the action of potassium hydroxide on the chlorohydroxystearic acid obtained from oleic acid. Similar isomerides are prepared by the action of potassium hydroxide solution on erucic and brassidic acids. When the chlorohydroxybehenic acid obtained from erucic acid is treated with aqueous or alcoholic potash the dihydroxybehenic acid is formed which melts at 99-100'; the latter acid is also a prodixct of the oxidation of brassidic acid with potassium permanganate. The chlorohydroxybehenic acid from brassidic acid yields the dihydr- oxybehenic acid melting a t 133'; and this acid is also prepared by the oxidation of erucic acid.By the action of potassium hydroxide on the additive compounds of hypochlorous acid with iso-oleic and iso-erucic acids a dihydroxystearic acid corresponding with oleic acid is formed,ORGANIC CHEMISTRY. 863 The formation of the dihydroxystearic acid of the lower melting point from oleic acid is represented as follows (1-111) :- B + C1* $! *[CH,]?Me F' Me[CH,j7* Y*H H*~*[CH,],*COOH H* y*[CH,l7=COOH OH OH IT. / B I [YHhMe HO-7 =H J HO* .[CH,]7Me H*?*[CH,]y*COOH H*y*[CH,]7*COOH OH OH 111. I v. The dihydroxystearic acid of higher melting point (IV) is formed from elaidic acid in a similar way. The intramolecular change from (I) to (11) may either occur during the addition of hypochlorous acid or during the action of the potassium hydroxide but it cannot take place a t a later stage for the dihydroxystearic acid melting at 93-45' prepared by oxidising elaidic acid undergoes no change when treated with potassium hydroxide.When oleic and erucic acids are heated with sulphurous anhydride or sodium hydrogen sulphite 50 per cent. of the acids are converted into ehidic and brassidic acids respectively (J. Buss. Chern. Xoc. 24 477) and elaidic acid when similarly treated yields oleic acid only 20 per cent of the acid however being attacked. I n these reactions sulpho-acids are probably intermediate products. By the action of silver oxide on the chloro- or better on the bromo- hydroxystearic acid prepared from oleic and elaidic acids the dihydroxystearic acid of higher melting point is formed together with another compound not yet examined.The abnormal formation of this dihydroxy-acid is probably due to the high temperature of the reaction. When the chlorohydroxystearic acid obtained from oleic acid is converted into the monacetyl derivative of the dihydroxy-acid and this then hydrolysed the dihydroxystearic acid melting at 128-1 29' is formed whilst from elaidic acid under similar conditions two dihydroxystearic acids are obtained the one melting a t 127-128' and the other at 93-95'. By the action of barium hydroxide on the chlorohydroxystearic acid prepared from elaidic acid a glycidic acid (V) is formed which melts at 57-60' and when treated with potassium hydroxide or dilute sulphuric acid yields the dihydroxystearic acid of higher melting point (TI).

The chlorohydroxystearic acid prepared from oleic acid when treated864 ABSTltACTS OF CHEMICAL PAPERS. with barium hydroxide yields glycidic acid in an uncrystallisable form and this acid when hydrolysed forms the dihydroxystearic acid of lower melting point whilst the chlorohydroxy-acid from iso-oleic acid forms the glycidic acid melting at 57-60' and the dihydroxystearic acid of higher melting point. The chlorohydroxy-acid from elaidic acid is thus less stable than that from oleic acid for it is changed into its stereoisomeride even by the action of weak reagents whilst the action of sulphurous anhydride on elaidic and oleic acids shows that of these acids the former is the more stable.

BERTHELOT (Compt. rend. 1899 129 483-491).-The action of bromine on propylene in presence of water is much more rapid than on trimethylene and affords a means of purifying the latter which however is slowly affected and if sufficient time is allowed is also completely absorbed. The difference between the rates of action is sufficient to permit of the use of bromine for the approximate analysis of a mixture of the two gases. When propyiic or isopropylic alcohol is heated with zinc chloride the product is mainly propylene mixed with small quantities of pro- pane hydrogen and liquid hydrocarbons but no trimethylene.Similar results are obtained with concentrated sulphuric acid. Trimethylene when heated with zinc chloride a t its melting point is gradually converted into propylene ; when heated alone it is almost Completely converted into propylene mixed with some paraffins ethylene and hydrogen.

Compare this vol. i 586 747).-The phenylic chlorocarbonates are decomposed by water very slowly a t the ordinary temperature but immediately at loo" with formation of normal phenylic carbonates and the pro- ducts of decomposition of carbonyl chloride. Similar decompositions are effected by the action of aqueous alkalis and solutions of basic lead acetate silver nitrate &c.With alkali alkyloxides a mixture of normal phenylic and alkylic carbonat'es is obtained. Aliphatic alcohols have little or no action on phenylic chlorocarbonates in the cold even in the presence of aluminium chloride but on heating the theoretical amount of hydrogen chloride is evolved and excellent yields of mixed phenylic alkylic carbonates are obtained. The temperature required to bring about this reaction depends on the molecular weight and the constitution of the alcohol employed and has been experimentally determined in the case of methylic (66") ethylic (78") normal and pro- pylic (goo) butylic (103") heptylic (1427 octylic (155") and benzglic (160") alcohols and also for isopropylic (86") isobutylic ( 9 9 O ) ordinary amylic (1 1 lo) and allylic (92") alcohols.Better yields are obtained with alcohols requiring high than with those requiring low tempera- tures. The following compounds have been prepared by the method described. Phenylic butylic carbonate is a colourless liquid boiling a t 129-130' under 25 mm. pressure has a sp. gr. 1.0507 a t 0" and a refractive index 1,47951 at 16.1".

Phenylic octylic carbonate is a colourless liquid boiling at 145" under 30 mm. pressure ; it has a sp. gr. 1.0432 a t Oo and a refractive index 1.47647 at 16.1".

Phenylic benzylic carbonate is a faintly yellow liquid which boils a t 180-190" under 30 mm. pressure has a sp. gr. 1*1366 at 0° and a refractive index 1,49141 at 15-79 Orthotolylic ethylic carbonate a colourless liquid boils a t 132' under 3 2 3 2876 ABSTRACTS OF CHEMICAL PAPERS. 30 mm. pressure has a sp. gr. 1.1 271 at O' and a refractve index 1.49399 at 15.7'.

Parachlorophenylic ethylic carbonate is a colourless liquid which boils at 135-145' under 30 mm. pressure has a sp. gr. 1.1726 a t O" and a refractive index 1.51700 at 15.7".

The specific gravity of the mixed phenylic alkylic carbonates de- creases as the molecular weight increases at least for the series of normal alcohols and the following measurements together with those already quoted show that a similar relation holds good for the indices of refraction.The numbers refer to the D-line at 15*7-16;1'; air temperature = 20'.

The second paper deals with the action of phenylic chlorocarbonates on phenols and on organic bases. Phenylic chlorocarbonates have no action on phenols in t h e cold even in the presence of aluminium chloride and on heating the only reaction which occursjs the decomposi- tion of the chlorocarbonate with the formation of carbonyl chloride and normal phenylic carbonate.A similar decomposition takes place with anhydrous alkali phenyloxides but by gradually adding a concentrated solution of the phenol in aqueous soda to a solution of the chloro- carbonate in benzene or ether mixed phenylic carbonates are readily obtained. Phenylic paratolylic carbonate prepared in this way from phenylic chlorocarbonate and sodium tolyloxide crystallises in slender colourless needles melting a t 94'. Phenylic guaiacylic carbonate melts at 82" phenylic paracldorophenylic cadonate a t 92' guaiacylic para- chlorophenylic carbonate a t 98" and guaiacylic paracresy lic carbonate at 99".Phenylic chlorocarbonates interact readily with ammonia in alcoholic solution and phenylic guaiacylic tolylic thymylic and parachloro- phenylic carbamates all of which have been obtained by other methods and previously described were prepared in this way.

All these compounds are insoluble in cold and almost insoluble in hot water but soluble in all organic solvents. They crystallise well from chloro- form and are insoluble in dilute acids. Phenylic dipropylcarbamate is a liquid which boils at 168' under 30 mm. pressure. When phenylic chlorocarbonate arid pyridine are mixed in alcoholic or ethereal solution considerable heat is developed probably due to the formation of a n unstable additive product which decomposes into normal phenylic carbonate and a compound of pyridine with carbonyl chloride. The latter compound which is also obtained as a yellowish- white precipitate by the direct action of pyridine on carbonyl chloride i n toluene solution appears to have the composition COCl,(C,H,N) and By C.MARTINI (Gaxxetta 1899 29 ii 60-64).-The dichlororthocresol obtained by the action of sulphuryl chloride (2 mols.) on orthocresol (1 mol.) is identical with the compound melting at 55" prepared by Claus and Riemann (Abstr. 1883 1111) by the direct action of chlorine.

By RUDOLF VON SCHILLING and DANIEL VORL~NDER (Annalen 1899 308 184-202).-The acidic properties of hydroresorcinols are as strongly marked as'those of 8-ketonic acids although the carboxyl group is absent.

COOH'UH and cyclic organic sub- '2 stances containing oxygen usually exhibit acidic properties more pro- nounced than those open-chain compounds of similar constitution ; for instance hydroresorcinol may be titrated with caustic alkali and phenol- phthalein whilst acetylacetone CH,* CO*CH:C(OH)*CH gives noORGANIC CHEMISTRY.879 definite end-point and comparison of the first-named substance with ethylicP-ketohexamethylenecarboxylate,CH,<~HHZ~~~~C*COOEt ' 6 1 I indicates that the acidic influence of the carbonyl group of t h e ring is more powerful than that of the carbonyl radicle. The authors have determined the electrolytic conductivity of certain hydroresorcinol derivatives and &ketonic acids in order to ascertain which group of compounds is the more powerfully acidic.

H.856 ABSTRACTS OF CHEMICAL PAPERS. Three Crystalline Forms of Dimetanitrodiphenylcarbamide. By A. OFFRET and HENRI V~TTENET (Bull. Xoc. Chinz. 1899 Liii] 21 788-797).-Further study of the crystalline forms assumed by di- metanitrodiphenylcarbamide has revealed the existence of a third isomeric modification in addition to the two which have already been shortly described (this vol. i 692). The a- and P-modifications are best obtained by slowly evaporating in a current of dry air a solution in 95 per cent alcohol of either of the three modifications or of a mixture thereof. I n this process the temperature should be main- tained nearly constant a t some point between 30" and 75O the higher temperature being most fnvourable to the production of the yellow crystals of the a-modification whilst a t lower temperatures the P-modi- fication which crystallises in white needles is formed in larger pro- portion.The third or y-modification crystallises in yellow plates and is obtained by the spontaneous evaporation a t the ordinary tem- perature of the alcoholic mother liquors from which the other two modifications have been separated. The formation of the three modi- fications depends entirely on the conditions under which crystallisation takes place and any one of the three forms may by suitable regulation of the temperature be converted into the other two.I n the presence of alcohol the y-modification is stable a t the ordinary temperature but entirely disappears a t about 40° its place being taken first by the P-modification which is most stable a t about 50" and then by the a-modification which is the most stable of the three forms. When heated in the dry state the a-modification remains unaltered until it melts at 242' ; the crystals of the P-modification become yellow and opaque at 180° and finally melt a t 242'; and the yellow crystals of the y-modification become white and opaque a t 60° finally melting a t 242'. If anhydrous acetic acid or a mixture of alcohol and acetic acid is used as the solvent the white needles of the P-modification only are obtained on cooling the solution. This action of acids ex- plains the fact that dimetanitrodiphenylcarbamide is obtained in the form of a white powder by the action of carbonyl chloride on meta- nitraniline whereas when phenylic carbonate is employed a yellow product is formed A detailed account of the crystallographic and optical properties of the three modifications is given in the paper ; each crystallises in the monoclinic system but the three forms are quite distinct.N. L. Preparation of Aromatic Thiocarbamides. By A. HUQERS- HOFF (Bey. 1899 32 2245-2249).-The reaction between aromatic amines and carbon bisulphide in presence of alcohol is greatly hastened by the presence of free sulphur.

Resolution of Racemic Amido-acids into Optically Active Components. By EMIL PISCHER (Bey. 1899 32 2451-2471).- Previous attempts t o resolve synthetical amido-acids into optically active components have been confined to fractional crystallisation and selective fermentation. The compounds in question are usually so feebly acidic and basic that their salts with alkaloids or with optically active acids do not lend themselves to resolution by crystallisation.The author has therefore increased the acidity of amidopropionic aspartic and glutamic acids by introducing the benzoyl radicle and then resolved the racemic benzoyl derivatives in to their optically active components by crystal- lising certain alkaloidal salts ; the active amido-acids are finally obtained by hydrolysing the benzoyl derivatives. 1-Benxoylalanine prepared by fractionally crystallising the brucine salt of racemic benzoylalanine crystallises from water in lustrous plates and melts a t 147-148" (150-151" corr.). It dissolves in 85 parts of water at ZOO and a 1 per cent. aqueous solution has [a] - 3.3' a t 20'. A solution in aqueous caustic soda has [UID- 37.3".

If the crude product of t h e reaction is rapidly heated with dilute alcohol so as to leave some un- dissolved and the solution cooled a white substance is obtained which melts at 136-137O and is soluble i n the ordinary solvents and in hot dilute hydrochloric acid but insoluble in alkalis arid only slightly soluble in water. This form which if not very pure reddens i n the air does not yield a n acetyl derivative.If however the original pro- duct of the reaction is treated with cold alcohol on filtering off the latter a white substance remains which when crystallised from boiling benzene or precipitated from its solution in acetone by adding alcohol forms a colourless crystalline powder melting and decomposing at 153' ; i t is insoluble in dilute sodium hydroxide solution or dilute hydrochloric acid slightly soluble in benzene or light petroleum and less soluble in alcohol than the other isomeride into which i t is gradually converted on keeping. The oxime melting at 153O forms an acetyl derivative C,,H,,O,N:NOAc which crystallises from dilute alcohol in long shin- ing needles melting a t 114c. The pherzylhydrccxone also exists in two forms probably the syn- and anti-modifications One of them is a sandy white non-crystalline powder which when purified by dissolving in chloroform and precipit- ating with light petroleum melts and decomposes at 79-80'.It is insoluble in water ether or sodium hydroxide solution bii t dissolves slightly in benzene or light petroleum and more so in alcohol or chloro- form ; on heating with dilute hydrochloric acid decomposition takes place with the separation of benzaldehyde. From t h e benzene-light petroleum mother liquors of this oxime another form is slowly deposited which separates from alcohol in shining white crystals melting at 138-139' with decomposition. On heating ethylic anilidobenzylacetoacetate with a mixture of equal volumes of glacial acetic acid and alcohol a substcmce is obtained which has the composition C16H,,0N and separates from benzene in large well-developed crystals melting at 155-156" ; in benzene solution it gives n molecular weight corresponding with the formula C,,H,,O,N,. It is a very stable neutral compound and is unchanged by boiling with alcoholic hydroxylamine or its hydrochloride ; i t dissolves in boil- ing acetic anhydride but does not separate unaltered.When dissolved in carbon bisulphide i t takes up bromine with evolution of heat and with iodine i t forms a compound containing 42-6 per cent.

A quantity of moist ethylic anilidobenzglacetoacetate when kept in a closed vessel for about six months changed spontaneously into the diethylic diphenyldihydrodicarbolutidinate obtained by Lachowicz by the prolonged action at the ordinary temperature of 2 mols.of aniline and 2 mols. of benzaldehyde on a n alcoholic solution of 1 mol. of ethylic acetoacetate. On the dry distillation of ethylic anilidobenzylacetoacetate a con- siderable quantity of symmetrical diphenylcarbamide is formed. T. H. P. Alkylmalononitriles and their Derivatives. By JOHX C. HESSLER (Amer. Chem.

On leaving the crude mixture in contact with aqueous ammonia during 24 hours ethylcyanacetamide (Henry loc.c i t . ) is formed whilst the ethylic dietlylcyccnacetute is not acted on and can be isolated by distilling under diminished pressure ; it is a colourless liquid which boils at 110-1 12" under 24 mm. and at 215-216" under ordinary pressure and when heated with concentrated hydrochloric acid at 100' yields diethylcyan- acetic acid (Hesse Abstr 1897 i 16).

When ethylic cyanacetate is treated with benzylic chloride (1 mol.) and sodium according t o the Conrad-Limpach method ethylic clibenzylcyanacetate (compare Cassirer Abstr. 1893 i 16) is formed together with about 20 per cent. of ethylic benzylcyanacetate CN*CH(CH,Ph)*COOEt ; the latter however is the principal product of the action of benzylic chloride on dry ethylic sodiocyanacetate at 80'. It is a colourless oil which boils at 176-183" under 20 mm. pressure and is not acted on by aqueous sodium carbonate; with cold caustic soda it yields sodium benzylcyanacetate but on warming sodium benzylmalonate is formed.Ethylic dibenzylcyanacetate is a viscid yellow syrup which boils at 337" under 25 mm. pressure and solidifies after several weeks to large colourless crystals melting a t 33" (compare Cassirer Zoc. cit.).

A. D. Synthesis of Unsaturated Dicarboxylic Acids from Ketones and Diethylic Succinate. By HANS STOBBE (Annalen 1899 308 67-88. Compare Abstr. 1896 i 234 and 1897 i 192).-In a former paper (Abstr. 1895 i 142) the author has shown t h a t when acetophenone and methyl ethyl ketone undergo condensation with diethylic succinate two isomeric acids are produced in each case. Those melting at the higher temperature decompose on fusion and were regarded as substituted itaconic acids for example y-methyl- phenylitaconic acid CMePh:C(COOH)-CH,*COOH from acetophenone ; t h e isomeric acids melting without decomposition were called aticonic acids and were looked upon as being stereoisomeric. Subsequent investigation however has rendered it more probable that they are structurally isomeric having the unsaturated linking i n the y6position relative t o the first carboxylic group; this refers them t o pyrotartaric acid and the substance formerly called phenylmethylaticonic acid becomes y-phenyl-y-methy Zenepyrotartaric acid CH CPh C( COOH)*CH,* COOH.The class name y-alkylenepyrotartaric acid is chosen to represent those acids which do not decompose on fusion (compare Fittig this vol. i 332). The following abstracts contain descriptions of the acids obtained by condensing other ketones with diethylic succinate. According to t h e constitution of the ketone condensation gives rise either t o a single itaconic acid a single alkylenepyrotsrtaric acid or a mixture of both acids. Thus benzophenone yields y-diphenylitaconic acid a s sole product whilst acetophenone gives rise t o y-phenyl-y-methylita- conic y-phenyl-y-met hylisoi taconic and y-phenyl-y-met hylenepyro- tartaric acids ; deoxybenzoin and dibenzyl ketone yield y-phenyl- y-benzylidenepyrotartaric acid and y-benzyl-y-benzylidenepyrotartaric acid respectively.Theoretical considerations occupy the remaining portion of the paper.

T. M. L. Action of Sulphonic Chlorides on the Metallic Derivatives of Ethereal Salts of Ketonic Acids. By ELMER P. KOHLER and MARGARET B. MACDONALD (Amer. Chem. J. 1899 22 22'7-239).- When paratoluenesulphonic chloride (1 mol.) is digested with ethylic sodacetoacetate (1; mols.) in ethereal solution for 1 hour on the water-bath tbe principal products are sodium paratoluenesulphinate and symmetrical diet h y lic diacetylsuccina te but e t hglic acetoacetate chloracetoacetate and paratoluenesulphonacetate C,H,Me*SO *CH2* COOEt are also formed ; it is probable that the first action is the formation of sodium paratoluenesulphinate and ethylic chloracetoacetate a portion of the latter then interacting with unchanged ethylic sodacetoacetate to form diethylic diacetylsuccinate whilst the remainder unites with the sodium paratoluenesulphinate yielding ethylic acetate and para- toluenesulphonacetate.Ethylic chloracetoacetate however does not act on sodium paratoluenesulphinate dissolved in benzene or ether but i n presence of alcohol ethylic acetate and paratoluenesulphon- acetate are rapidly formed a t the ordinary temperature; the action probably takes place in two stages I.

When the mixture is warmed the action takes place differently the sulphinate being oxidised to sulphonate whilst ethylic acetoacetate is formed. The ethylic paratoluenesulphonacetoacetate formed according to equa- tion I could not be isolated ; the sodium derivative was obtained how- ever in small amount together with sodium paratoluenesulphinate diethylic diacetylsuccinate sodium mercaptide and ethylic aceto- acetate on boiling an ethereal solution of equivalent quantities of ethylic sodacetoacetate and ethylic paratoluenethiosulphonate C,H,Me*SO,*SEt for 30-40 hours when it separated as a hard granular deposit. It is rapidly decomposed by water into sodium acetate and ethylic paratoluenesulphonacetate whilst the sodium derivative C,H,Me*SO,-CHNa*COOEt of the latter together with ethylic acetate are formed when it is treated with cold absolute alcohol; aqueous and alcoholic potash convert it into tolylmethylsulphone. When a mixture of ethylic malonate paratoluenesulphonic chloride and sodium ethoxide in ethereal solution is heated on the water-bath for several hours the principal products are ethylic ethylenetetra- carboxylate and sodium paratoluenesulphinate ; ethylic paratoluene- sulphonosodacetate is also obtained probably owing t o the inter- action of the paratoluenesulphinate with ethylic chloromalonate and subsequent hydrolysis of the ethylic pa~atoluenesulphonomalonate C,H,Me*SO,* CH(COOEt) formed.This agrees with the fact that when paratoluenesulphonic chloride is shaken with ethylic disodio- malonate in absolute alcohol the disodium derivative C,H,Me SO,* CNs( COOE t) COONa 3 1' 2908 ABSTRACTS OF CHEMICAL PAPERS.of monethylic paratoluenesulphonomalonate is obtained ; on acidifying a n aqueous solution of the latter with hydrochloric acid carbonic anhydride and ethylic paratoluenesulphonaceta-te are formed.

By JOSEPH H. JAMES (J. Anaer. Chenz. Soc; 2899 21 889-910).-'The electrolytic oxida- tion of benzoin in alcoholic sodirim hydroxide gives the maximum yield of benzoic acid when a normal current density of 0.25 ampere is employed; with higher densities less acid and more tarr,y matter are formed. In alcoholic sulphuric acid solution a density of 0.5 ampere is required in order t o bring about oxidation the products being the same as in the alkaline solution.I n alcoholic hydrogen chloride solution with a density of 1 ampbe the products are henzoic acid and benzil but when currents of higher density are employed benzil alone is formed. The electrolytic reduction of benzoin in both alcoholic sulphuric acid and ~lcoholic hydrogen chloride solution gives rise to small quantities of a crystalline compound melting a t 205-206" the composition of which could not be determined. The oxidation of benzil in alcoholic sodium hydroxide solution yields no definite products but in alcoholic sul- phuric acid solution benzoic acid (14.5 per cent.) may be obtained ; in hydrogen chloride solution no change takes place when a current of 1 amphe is employed and on increasing the density t o 7 amphres only tarry products are formed.By the electrolytic reduction oE benzil in alcoholic sulphuric acid benzoiwand a small amount of the substance melting a t 205-206" are produced ; benzoin is also formed when an alcoholic hydrogen chloride solution is employed but no definite products can be isolated when the reduction takes place in alcoholic sodium hydroxide solution. J. J. S . Phenylhydrazones of Benzoin. By ALEXANDER SMITH (Amer. Clhn. J. 1899 22 198-207).-The author confirms Smith and Ransome's statement (Abstr. 1894 i 293) which Preer(Amer. Chem. J. 1899 21 14) has recently called in question t h a t benzoin-/I-phenyl- hydrazone is converted into the a-compound when boiled with aIcoholic phenylhydrazine.The '' y-phenylhydrazone," obtained by Freer (this vol. i 357) by the action of benzoic chloride on an ethereal solution of the P-isomeride is in reality benzanilide amtnonium chloride and benzil being also formed. Contrary to Freer's statement the a-phenylhydrazone when treated with benzoic chloride at the ordinary temperature yields the same products a s the @-compound and when oxidised with nitrous anhydride gives rise to' a considerable quantity of the red substance meltkg at 1 3 7 O described by Freer as being formed only fron the /3-hydrazone. It thus appears either t h a t both the phenylhydrazones of benzoin have the hydrazo-structure or that contrary t o Freer's assumption the formation of red compounds by the action of nitrous anhydride may occur in the case of t r u e hydrazones.W.

Chena. 1899 [ii] 60 244-254. Compare this vol. i 68).-When formic acid actson geraniol at 0' to 5O the chief pro- duct is geranyl formate whilst on warming terpinene is formed; at aORGANIC CHEMISTRY. 92L temperature of 1 5 O to 20° however the product consists largely of terpinyl formate. After the action had proceeded for 12 days the product is hydrolysed distilled in a current of steam and fractionated under 13 mm. pressure ; the fraction of lowest boiling point had the characteristic odour of terpinene but the nitrite could not be prepared ; 72 per cent.of the substance however distilled between 102’ and 104’ and solidified on cooling ; the crystals were drained and crgstallised from light petroleum and showed the normal density melting point boiling point refractive index and absence of rotatory power characteristic of cajeput oil. About 15 per cent. of the geraniol had been converted into terpineol. Neither acetic acid nor acetic anhydride will convert geraniol into terpineol but this change takes place rapidly on warming with acetic acid containing 1-2 per cent. of sulphuric acid and more slowly but with a better yield of terpineol when the action takes place a t the ordinary temperature.For the separation of geraniol and terpineol phthalic anhydride is used which combines readily with the primary alcohols to form acid esters but only slowly with secondary and not a t all with tertiary alcohols ; after neutralising the solution with soda the unchanged terpineol can be extracted with ether whilst sodium geranyl phthalate remains behind and can be hydrolysed with caustic alkalis. Theconversion of geraniol into terpineol is explained by the for- mation of an additive product with two molecules of acid which are subsequently split off with formation of a ring-compound; this intermediate product should be identical with that which is assumed to be formed in the conversion of linalool into terpineol but it could not be isolated in either case. By shaking with 5 per cent.sulphuric acid for 10 days and boiling the terpin hydrate formed with dilute sulphuric acid geraniol can also be converted into a liquid terpineol identical with that prepared from pinene. When steam is passed into an aqueous solution of sodium geranyl phthalate there is produced together with geraniol a considerable amount of inactive linalool. This affords a third method of passing from geraniol to linalool (compare Tiemann Ber. 1898 31 832 and Schimmel’s Bevichte April 1898 25). T. M. L.

Isolauronolic wldehyde C,H,,- CHO prepared by distilling a mixture of calcium isolauronolate and calcium formate is a colourless mobile liquid having an agreeable penetrating odour ; it boils at 170' under 760 mm. pressure and its sp. gr. is 0.S930 at 15'.

The ammonium strontium rnagmsium manganese and cadnaium salts of isolauronolic acid are crystalline and the ferric salt which is in- soluble in water and alcohol crystallises from ether ; the amylic salt boiling at 260' has a sp.gr. 0.9378 a t 15') and the phenylic a-naph- thylic and P-nuphthylic ethers melt a t 24.5' S2' and 82' respectively. The unhydride is a viscous liquid which boils a t 210-215' under 1 3 mm. pressure and has a sp. gr. 1.0287 at 15'. Both the orthotolzcidide and parutoluidide melt at 114' and the a-maphthalide and P-naphthalide at 148-149'. Isolaurornolic alcohol C,H,,* CH,.

CMe Q*COOH CH2-CH2 1.The acid is optically inactive. CHMe*EH It is next pointed out that the formula CMe2<0131,-C.CooH~ by whbh Perkin represents isolauronolic acid is reachei by ascribing the constitution SMe2* ?Mes->CO to isolauronic acid which he CH,-C(COOH) regards as the immedikte Goduct Af oxidation this formula being based on the assumption that dihydroisolauronic acid the product of re- duction with sodium amalgam is an alcohol-acid which does not form a lactone. Repetition of his own experiments and a study of iso- lauronic acid however have led the author to results which confirm his previous conclusions but are antagonistic to those of Perkin. I n the first place purified isolauronolic acid is optically inactive.It is dimorphous being obtainable in hexagonal prisms and large slender plates belonging to the monoclinic system and in octahedra belonging to the orthorhombic system all three varietlies melting a t 135'. I f the anhydride of rncemic camphoric acid is employed for its production instead of dextrocamphoric anhydride the product is the same and cannot be resolved into optically active components by crystallising the cinchonine salt. Moreover according to the author's view of the structure of isolauronolic acid the compound obtained by Burcker from the action of camphoric anhydride on benzene in presence of aluminium chloride (A.bstr. 1895 i 108; 1896 i 179) should be opticallv active and this is the case.

The methylic salt melts a t 93-94' and gives aD + 11" 53' at 24" whilst the isobzctylic salt melts at 71-72' and gives uD - 1" 30' a t 23'. The chloride crystallises in white needles melting at about 60° and is very readily soluble in neutral solvents ; moist air decomposes it and when heated in a vacuum at about 150°,ORGANIC CHEMISTRY. 921 it is resolved into hydrogen chloride carbonic oxide and the un- saturated hydrocwbon Cl4HIS a somewhat viscous liquid which boils at 195-200' under 40 mm. pressure. When isolauronolic acid is oxidised with potassium permanganate at Oo isolauronic acid is the main product whilst oxalic dimethyl- succinic and dimethylhexanonic acids are formed in subordinate amount ; if the operation is conducted at common temperatures more than double the quantity of potassium permanganate is required and the main products are oxalic and dimethylsuccinic acids the amount of dimethylhexanonic and isolauronic acids being comparatively small.On oxidising the last-named substance with potassium permanganate at 15-20' oxalic and dimethylsuccinic acids are produced unaccom- panied by a trace of dirnethylhexanonic acid; according to Perkin (Zoc. cit.) this compound is formed when oxidation is effected by means of a mixture of chromic and sulphuric acids but the quantity does not seem to be large From these experiments the author con- cludes that isolauronic acid is not the immediate result of oxidising isolauronolic acid but represents a stage subsequent to the formation of dimethylhexanonic acid.The final argument is based on the nature of dihydroisolauronic acid. As already stated this compound is obtained on reducing iso- lauronic acid with sodium amalgam and is regarded by Perkin as an - - - alcohol-acid FMe->CH*OH mainly on account of its in- CH,-C(CO0H) ability to form a"1act'one. The author finds however that dihydro- isolauronic acid is a ketone-acid being not only indifferent towards acetic chloride but capable of uniting with hydroxylamine and semi- carbazide; the oxirne and semica?*baxone melt and decompose a t 210' and 229' respectively. Dihydroisolauronic acid boils under the ordinary pressure without decomposition and in consequence cannot have the ketonic group in the P-position with regard to carboxyl; it is therefore most probably a )-ketone and the y-hydroxy-acid obtain- able from it by reduction should be convertible into a lactone.This has been found to be the case. IsoZcu?*onoZide C,H1,02 prepared by reducing dihydroisolauronic acid with sodium in absolute alcohol has a faint odour of camphor and melts a t 53-54"; hydrolysis converts it into tetrahyd~oisolccuronic acid CoH1603 which crystallises from benzene in small prisms and melts a t 142-143'. I n the author's estimation these facts point to the formulae C M e ~ < ~ ~ c H 2 S C * C O O H and CM~~<CH,. c 0 ~ c H 2 > ~ ~ * ~ ~ CH for isolauronic and dihydroisolauronic acids respectively.The ex- pressions accord with t i e conversion of the latter into tetrahydroiso- lauronic acid CMe2<CH,--cH CH(oH)* CH2>CH*COOH and isolauronolide CMe,*CH-0 CH,/ >CH 1 on reduction and the resolution of isolauronic acid into aa-dimethylsuccinic and dimethylhexanonic acids by oxidation.

Perkin's Constitutional Formula for Camphoric Acid. By G. BLANC (Bull. SOC. Chim. 1899 [iii] 21 854-863. Compare foregoing abstract}.-Whilst admitting that Perkin's formula explains the production of dimethylmalonic trimethglsuccinic and carnphoronic acids when camphoric acid is oxidised the author points out that the formation of the acid C,H,,O along with oxalic acid observed by Balbiano is incompatible with it (compare this vol.i 537). Proceeding t o deduce from Perkin's formula constitutional expressions for im- portant members of the isolnuronolic and campholenic series the author shows that conclusions t o be drawn from this source are not easily reconciled with facts.

The second and third of these the author considers improbable from the fact that hydroxydihydrocnmpholytic acid does not yield a lactone when treated with dilute sulphuric acid and therefore can hardly be a y-hydroxy-acid aud that hydroxylauronic acid not only does not yield a lactone but on treatment with potassium dichromate and sulphuric acid loses carbonic anhydride and passes into a ketone appearing therefore t o be a P-hydroxy-acid.

By CARL NEUBERCI (Bey.1899 32 2395-2398).-If an aqueous solution of glycuronic acid is heated to boiling and treated with parabromophenylhydrazine acetate under certain conditions a compound separates in bright yellow needles and may be purified by washing with water and a,bsolute alcohol successively and repeated crystallisation from 60 per cent. alcohol. The new substance whose exact nature has not yet been determined has the composition C,,HI7O7N,Br; i t is sparingly soluble in hot water benzene ether ethylic acetate absolute alcohol or amylic alcohol insoluble in chloroform somewhat readily soluble in hot glacial acetic acid and in 60 per cent. alcohol. Its alcoholic solution is strongly dextrorotatory. I t is scarcely altered by boiling with baryta water or ammonia and does not give Bulow's reaction for acid hydrazides ; the crystals when moistened with alcohol quickly redden magenta sul- phurous acid.The cupric-reducing power is diminished after treat- ment with 1 per cent. alcoholic hydrogen chloride a behaviour which might indicate that acetal formation had occurred. It appears to combine with hydroxylamine but an oxime could not be isolated and i t was not found possible to obtain derivatives containing more hydrazine owing to the formation of resinous products. The application of the above observation to the detection of glycuronic acid in urine is being investigated; it is to be noted that urochloralic acid yields the same compound after preliminary hydrolysis with dilute sulphuric acid. A. L. By ANTOINE P. N. FRANCHIMONT (Rec. Trav.Chirn. 18 334-350).-The plumieride isolated by Eoorsma from the bark of Plumierct acutifolia appears to be identical with the substance obtained by Merck (Abstr. 1897 i 167) from the same source although the former investigator stated that i t did not melt whereas the latter gave its melting point as 157-158O. The author finds that the sub- stance melting at 157' is the hydrated form of plumieride; when crystallised from dry ethylic acetate i t separates in the anhydrous con- dition and then has no definite melting point. A molecular weight determination by the cryoscopic method gave numbers varying from 537 to 572; these values are approximately half those obtained bj Merck who used the ebullioscopic method. Plurnieride is a glucoside for when boiled with 5 pel. cent.hydrochloric acid i t is hydrolysed yielding glucose and an insoluble amorphous brown substance. An acid for which the author proposes the name plumieridic acid is pro- duced by dissolving plurnieride in aqueous potash and alloving the solution to remain for some time; the solution when acidified with Plumieride.934 ABSTBACTS OF CHEMICAL PAPERS dilute sulphuric acid yields the new compound which is sparingly soluble in water. This acid is slightly soluble in methylic alcohol and insoluble in ethylic alcohol ether chloroform or benzene ; it decom- poses a t temperatures above 2009 ; its dilute aqueous solution is lsvo- rotatory. The potassium salt crystallises from water. Plumieridic acid is also a glucoside for on boiling with 5 per cent.hydrochloric acid it behaves like plumieride yielding glucose and an amorphous brown substance. Plumieride seems also to be identical with agoniadin obtained by Peckolt (Arch. Pharnz. 1870 ii 142 40) from P. luncifolia for the latter substance behaves similarly on hydrolysis and melts at 155'. 2 2' 6 :6'-Tetramethyldipyridyl and the Corresponding Tetra- carboxylic Acid.

Isoamylpiperidine forms an u w i - chloride melting at 12s" and a picrate melting a t 133' ; its oxide forms an oily aurichloride and a picrate crystallising in needles and melting at 11 2" and does not react with platinic chloride. Isoamylpiperidine oxide is reconverted into isoamylpiperidine by heating it alone or with hydrochloric or hydriodic acid ; in the last case the yield of tertiary base is quantitative.The sdphonic anhydride prepared by passing sulphurous anhydride into an aqueous solution of the oxide separates in white crystals melting at 141" ; in the presence of barium chloride isoamylpiperidine hydrochloride and barium sulphate are produced.

On reduction with sodium and ethylic alcohol 2 6-di- methylpyridine yields 2 6-dimethylpiperidine (lupetidine) and a new isomeride isolupetidins ; the two bases are separated by washing their hydrochlorides with acetone when the isolupetidine salt passes into solution.The following salts o€ lupetidine were prepared the hydro- bi*ornide melting a t 285'; the acid tartrccte melting a t 79' and the picrate at 162-164'.

Action of Phosphorus Tribromide on Isomeric Monatomic Saturated Alcohols. Allylpiperidine. Allyldipropylamine. By NICOLAI A. MENSCEIUTKIN (Chem. Centr. 1899 i 1066-1067 ; from J. Buss. Chern. Soc. 1899 31 43-45).-By the action of phosphorus tribromide on ethylic isobutylic isopropylic and tertiary amylic alcohol large yields of the corresponding monobromides are obtained in a pure state,and the residue from the distillation consists of almost pure phosphorous acid.When a mixture of solutions of piperidine and allylic bromide in benzene is heated on the water-bath a theoretical yield of almost pure piperidine hydrobromide (which does not contain any diallylpiperidine ammonium hydrobromide) is obtained and the filtrate when fraction- ated yields a2lylpiperidirne. The latter boils at 151-152' and has a sp. gr. 0.8445 at 18.5'; the aurichloride forms a tough mass which is only soluble in hot water ; the pkatinochloride (C,H,* C5NH,0)2,H2PtC16 crystallises in dark orange prisms.By the action of dipropylamine on allylic bromide dissolved in benzene an almost theoretical yield of dipropylamine hydrobromide is obtained and the solution yields allyldipropykarnine which boils at 150-152O and has a sp. gr. 0.7587 a t 16'.

The platinochloride (C3H,*NPr,),,H2PtCl + H,O forms clear orange crystals. The preparation of these ally1 compounds is not complicated by bye- reactions as in the case of the action of methylic bromide on ammonia (compare Dubowsky this vol. i 854). E. W.W. Nitroao-indoles. By ANGELO ANGELI and MATTEO SPICA (Gaxxetta 1899 29 i 500-503).-When treated with nitrous acid indoles with substituent alkyl radicles in the 3’- or 2’ 3’-positions,. give true nitrosamines whilst if the alkyl group be in the 2’-positron only compounds are obtained which have been regarded as nitroso deri- vatives. Thus 2’-phenylindole yields a nitroso-2’-phenylindole which is a yellow substance dissolving in alkali solutions with intense orange coloration and readily yielding an acetyl derivative ; it does not react with hydroxylamine. These properties are not in accord with those of the true nitroso-derivatives which are coloured green or blue and react with hydroxylamine giving in the case of aromatic derivatives diazo-compounds and in the case of the nitrosamines the primitive amine with evolution of nitric oxide. From these considerations the authors are of opinion that nitroso-2’-phenylindole is represented by the formula N<2F{>C:NOH corresponding with the ketone N<2$>UO.This formula containing the grouping -C(NOH)-C=N- bears out the analogy which these compounds show to the nitroso- phenols which contain the chain -C(NOH)-C=C-. T. H. P. 3’-Nitroso-indoles. By MATTEO SPICA and F. ANGELICO (Gaxxettcb 1899 29 ii 49-60).-The authors regard 3’-nitroso-indoles as contain- ing the group NOH united to the carbou atom in the 3‘-position of the indole nucleus. Such a constitution would indicate a method of pre- paration of these compounds by acting on the indole with amylic nitrite in presence of sodium ethoxide and this method is now shown t o give almost quantitative yields of nitroso-indoles identical with those obtained by means of nitrous acid in acid solution.Isonitroso-2’-phenylindole gives an acetyl derivative C8H,NPh:NOAc crystallising from light petroleum in shining red needles melting at 12l0 and a benxoyl derivative which separates from benzene in brilliant red needles soluble in alcohol and slightly so in light petroleum and melting a t 151-152” without decomposing. ~sonitroso-2’-methyZindoZe C8H,NMe:NOH obtained from 2’-methyl- ketole separates from alcohol in brilliant yellowish-green plates which change in the air and melt with decomposition at 198O; acetic acid dissolves it forming an intensely reddish-brown solution. It has both a basic and an acid character! yielding a potassium salt and a hydro- chloride ; with benzaldehyde it gives no condensation product showing that the indole character is lost.Its stability towards permanganate in alcoholic solution points to the absence of a double linking betweenORGANIC CHEMISTRY. 939 two carbon atoms. The potassium salt C,H,ON,K forms orange- yellow acicular crystals which in the air rapidly absorb moisture and carbonic anhydride and decompose. Isonitroso-2'-methylindole h9drochloride forms an olive-green crystal- line mass which readily loses hydrogen chloride in the air and is soluble in water with partial decomposition. IsonitrosopyrroZiPe C,H,N:NOH obtained by the action of amylic nitrite on pyrroline in presence of sodium ethoxide is a yellowish- brown precipitate which rapidly blackens in the air.Its sodium derivative forms orange-coloured crystals. T. H. P. Constitution and Reactions of (' Isatoic Acid.'' By ERNST ERDMANN (Ber. 1899 32 2159-2172).-Kolbe's isatoic acid (Abstr. 1885 58) has according to E. von Meyer the constitution C,H,</.,O 2 whereas Niementowski and Rozanski (Abstr. 1889 N-C00H NH-YO 996) represent it by the formula C,H,<co. . The author brings forward the following reasons for supporting the second constitu- tion i. Methylic chlorocarbonate reacts with anthranilic acid in the same manner as the ethylic salt yielding phenylurethanecarboxylic acid melting at 181" and this is identical with the product formed by the action of methylic alcohol on " isatoic acid." 3. Phenylurethane- carboxylic acid when etherified with methylic alcohol yields a neutral etheric salt melting at 6lC which is also obtained when methylic chlorocarbonate reacts with methylic anthranilate.3. " Isatoic acid " is most readily obtained by the action of carbonyl chloride on an aqueous solution of sodium anthranilate. '' Isatoic acid " is thus not an acid but the anhydride of a dicarboxylic acid COOH*C,H,*NH*COOH. The author calls this dibasic acid isatoic acid and the anhydride previously known as isatoic acid he terms isatoic ccnhydride. The formation of the anhydride by the action of ethylic chlorocarbonate on anthranil a t 140" is easy to understand if the old formula C,H,<CO) for anthranil is accepted and the formation of an additive product COCI*C,H,*NH*COOEt assumed as this by loss of ethylic chloride would give isatoic anhydride.A yield of some 50 per cent. of the anhydride is obtained by Niementowski and Rozailski's method provided an excess of ethylic chlorocarbonate is employed and the mixture is boiled long enough. The simplest method is however to pass carbonyl chloride into an aqueous solution OF sodium anthranilate and to crystallise the pre- cipitated anhydride from alcohol; it is thus obtained in the form of glistening prisms ; it crystallises from its aqueous solutions in colour- less needles ; the tempe ature at which it decomposes appears t o vary greatly (240-290°) according to the medium from which it crystal- lises. The anhydride has no acid reaction towards moist litmus paper and dissolves but slowly in cold sodium carbonate solution and may be precipitated unchanged on the addition of acids.Prolonged contact however with sodium carbonate decomposes it into carbonic anhydride and anthranilic acid together with an acid C1,H,,O,N probably NH 3 t 2940 ABSTRACTS OF CHEMICAL PAPERS. diphenylcarbarnidedicas.60xylz’c acid CO( NH* C,H,*COOH),. A better yield of this acid is obtained when hot sodium carbonate solution is employed ; it crystallises from dilute alcohol melts and decomposes at 165O has a strongly acid reaction is readily soluble in alcohol and only very sparingly in water; when heated with lime it yields diphenylamine and aniline. Its sodium salt C15Hl,05N,Na2 + H,O forms colourless crystalline crusts and is readily soluble in water.When isatoic anhydride is heated with methylic alcohol at 130’ (compare Schmidt and Meyer Abstr. 1888 371) the chief product is rrzethylic hydrogen iscctoccte (phenylurethanecarboxylate) COOH- C,H,*NH*COOMe which crystallises from dilute alcohol in colourless needles melting a t 181’; it is identical with the product formed by the action of methylic chlorocarbonate on anthranilic acid and also with the compound described by Schmidt as methylic carb- oxyanthranilate. I n addition to the acid etheric salt described above an oily bye-product containing anthranilic acid methylic anthranilate and dimethylic isatoate is also formed. I t has been found impossible t o convert the acid etheric salt into methylic anthranilate either by heating with methylic alcohol or with glycerol (compare Schmidt Zoc.cit.) ; with the latter reagent a small quantity of a volatile syrupy base has been obtained but its constitution has not been determined Dirnethylic isatoate COOMe* C,H,*NH*COOMe is best obtained by boiling equal quantities of methylic chlorocarbonate and methylic anthranilate for an hour ; it may also be obtained by further etherify- ing the acid etheric salt; it crystallises in glistening white needles melting a t 61’ is readily soluble in alcohol but only sparingly in benz- ene and is readily volatile in steam. J. J. 5. Formation of 2’-Alkylquinoline-4’-carboxylic Acid. By KARL GARZAROLLI-THURNLACKH (Bey. 189 9 32 2 2 74-22 7 7) .-Doe bner (Abstr. 1887 504 ; 1 888 300) first prepared 2’-phenylquinoline-4‘- carboxylic acid by the interaction of aniline benzaldehyde and pyruvic acid in benzene solution at 100’; a t the same time a neutral substance C2,H1,0N was also formed which had previously been obtained by him from the same condensation in ethereal solution a t the ordinary temperature.The author considered that in this reaction either (I) the benzyl- ideiieaniline formed by the condensation of benzaldehyde with aniline combined with pyruvic acid to form a-keto-y-aailidophenylbutyric acid NHPh* CHPh* CH,. CO*COOH or (11) the benzylideneaniline combined with pyruvic acid to form NPh:CMe*COOH and benznldehyde which again condensed to form a-anil-7-hydroxyphenylbutyric acid OH- CHPh- CH,* C(NPh)*COOH. I n the first case by the elimination of water 2’-phenyldihydro- quinoline-4‘-carboxylic acid would be produced which by the elimina- tion of 2 atoms of hydrogen and rearrangement would be transformed into 2’-phenylquinoline-4’-carboxylic acid ; in the second case by a similar process 4’-phenylquinoline-2’-carboxylic acid would be formed.In order to settle this point molecular quantities of benzylidene- aniline and pyruvic acid were warmed togther in alcoholic solution when Doebner’s neutral substance C2,HI80N2 separated and from theORGANIC CHEBIISTRY. 041 mother liquors 2'-phenylquinoline-4'-carboxylic acid was obtained and showed complete identity with Doebner's acid. It is evident that Doebner and von Miller's quinaldine synthesis can be explained in the same way. J. F. T. 5-Chloro-1-phenyl-3-methylpyrazole. By AUGUST MICHAELIS and R.PASTERNACK (Bey. 1899 32 2398-2412).-This oily sub- stance obtained . by heating 1-phenyl- 3 4-dimethyl-5-pyrazolone with phosphorus oxychloride (this vol. i 333) is not a chlorophenyldimethyl- pyrazole as was at first supposed but 5-cl'LZoro-l-p~enyl-3-methylpy~*axole Nph<Ny(?Me It is formed by the elimination of methylic chloride from the methochloride of chlorophenylmethylpyrazole produced in t h e first stage of the reaction. It is most easily obtained by heating l-phenyl-3-methyl-5-pyrazole with phosphorus oxychloride and forms a thick colourless liquid with a characteristic odour and boils un- altered a t 261' under ordinary pressures a t 148' under 20 mm. and a t 134' under 10 mm. pressure ; it has a sp. gr. 1.1999 at 18'.

Compare Abstr 1898 i 277).-By means of phosphorus pentachloride derivatives of urazole and of 3- and 5-pyrrodiszolone are reduced to pyrrodiaqole compounds and pyrrazolones similarly yield pyrrazoles.I n the case of phenyl- urazole and paratolylurazole however Pellizzari and Ferro (this vol. i 550) have shown that by moderating the action of the phosphorus pentasulphide intermediate compounds consisting of phenyl- and tolyl- derivatives of 3-thiotriazolone and of 3-thiobistriazole are obtained. With a view to discovering the mechanism of the reducing action of the pentasulphide the authors have attempted to reduce these thio- compounds to pyrrodiazole derivatives by means of hydrogen sulphide or ammonium sulphide but negative results were obtained.ORGANIC CHEMISTRY. 947 That the reducing action is not due to hydrogen phosphides is shown by the failure of the reaction of these phosphides with l-phenyl- 3-methyl-5-pyrrodiazolone to yield a reduction product ; with the same compound neither phosphorous acid nor ordinary phosphorus gave a definite product.The action of phosphorus oxychloride on phenylpyrrodiazolone gives rise only t o the formation of phosphorus compounds but if the tri- chloride be present phenylpyrrodiazole is obtained. It is concluded that in the reduction of pyrrodiazolones by chlorine or sulphur compounds of phosphorus the reducing action is not exerted directly on the pyrrodiazolone but on intermediate chloro- or thio- derivatives.

SKRAUP (Monatsh. 1889,20 571-584).-A critical examination of the alleged isomerides of cinchinone Hesse's a- and P-isocinchonine (Abstr. 1893 i 677) are easily separated in the form of the dihydriodides that of a-ieocinchonine being easily soiuble and that of P-isocinchonine almost insoluble in cold water. These two and the two isomerides 6- and c-cinchonine obtained by Cordier (Xonatsh. 1898 19 472) from hydro- bromocinchonine are well characterised by their specific rotatory powers and therg can be no doubt that they are actual isomerides of cinchonine.Cordier's tautocinchonine (Zoc. cit.) is very similar to cinchonine but the differences in the solubilities of the two bases in alcohol and of their sulphates in water point to tautocinchonine being a true isomeride of cinchonine. Messe's 6 ' apocinchonine," "apoisocinchs-ORGANIC CHEMISTRY. 961 nine ” and (‘ isonpocinchonine ” are one and the same compound which is identical with Lippmann and Fleissner’s allocinchonine (Abstr. 1893 i 738). Allocinchonine is well characterised by the sparing solubility of its normal sulphate in water ( 1 part in 120 a t 20’). The “ cinchonifine of Jungfleisch and Ldger (Abstr. 1888 380) is probably cinchotine with which Hesse’s pseudocinchonine is identical (von Arlt this vol.i 962). After a close comparison of the sulphate and platinochloride of Hesse’s homocinchonine with the corresponding compounds of cin- chonine the author comes to the opinion that the two bases are identical. Jungfleisch and LQger (Abstr. 1892 1253) have stated that Hesse’s diapocinchonine is a mixture of a- and P-isocinchonine. This is disputed by Hesse (Zoc. c i t . ) but now confirmed by the author who has separated a- and P-isocinchonine from ‘‘ diapocinchonine ’’ by means of the dihydriodides. The directions given by Pum (Abstr. 1893 i 181) for the prepara- tion of p- and y-cinchonine were followed but the substance obtained was allocinchonine. Hydrochlorapocinchonine and hydrochlorapoisocinchonine were pre- pared according to Hesse’s method.From a redetermination of the solubilities of the bases and their salts there is no doubt that they are both identical with hydrochlorocinchonine. This however differs SO much from hydrochloro-a-isocinchonine that there is no possibility that they are identical. R. H. P. Molecular Transformations the Transformation of Gin- chonine into a-Isocinchonine. By ZDENKO H. SKRAUP (Monatsh. 1899 20 585-6 16).-If hydrochloric hydrobromic or hydrkdic acid acts on cinchonine at the ordinary temperature a portion of the cinchonine is transformed into a-isocinchinone and another portion converted into a n additive compound. I n this paper the data of a large number of experiments with acids of ten and fourteen times normal strength and the quantities of a-isocinchonine and the addition products thus formed a t different intervals are given.Much time is taken for the completion of the reactions but only the results obtained a t the beginning of the actions are of any value since a secondary reaction between the a-isocinchonine and the acid interferes after a short time. The velocities with which hydriodic hydrobromic and hydrochloric acids form the additive compounds are in the proportion of 200,000 400 1. The quantities of cinchonine trans- formed into a-isocinchonine in the same time by these acids are in the proportion of 10 2.6 1 and the ratio of the amount of cinchonine transformed into a-isocinchonine to that converted into an additive compound varies for each acid but is independent of the concentration time or temperature.This transformation cannot be referred to the action of ions for the amounts of cinchonine transformed into a-isocinchonine by the three acids bear no proportion to their electrical conductivities. Further it is noteworthy that nitric acid will not effect the transformation. The results show that this molecular transformation i s dependent on962 ABSTRACTS OF CHEMICAL PAPERS a second reaction taking place at the same time (compare the author's views on the conversion of maleic acid into fumaric acid (Abstr. 1891 1338).

On the addition of alcohol the salt crjstallises out in the form of large lustrous prisms.R. H. P. Pseudocinchonine and the Behaviour of Hydrochloro- cinchonine. By F. YON ARLT (Moncbtsh. 1899 20 425-449).- This is a repetition of Hesse's work on the same subject (Abstr. 1893 i 617). The author treats cinchonine dihydrochloride with hydrochloric acid of sp. gr. 1.160 a t 100' (instead of at SO'). About 29 per cent. of the cinchonine is converted into hydrochlorocinchonine dihydrochloride which crystallises out of the solution. The mother liquor is treated according to Hesse's method with ammonia and ether. 64 per cent. of the cinchonine is thus obtained as pseudocinchonine and about 8 per cent. as a mixture of bases easily soluble in ether. The crude pseudocinchonine is purified by treatment of its crude hydrochloride with alcoholic potash reconversion of the base into the hydrochloride and crystallisation of the latter. By neutralising and crgstallising the mother liquor Hesse's apoisocinchonine can be ob- tained.From its melting point (214-217") and the solubility (1 pt. in 11747 pts. of water) of its sulphate (C1,H,,ON,),,H,SO + l&H,O there is little doubt of its identity with Lippmann and Fleissner's allocinchonine (Abstr. 1893 i 738). The mother liquor obtained after treating the crude pseudo- cinchonine hydrochloride with alcoholic potash yields another alkaloid. This melts at 141° has a specific rotatory power in alcoholic solution ( p = 1) [a] + 140.7" at ZOO and is probably identical with Cordier's 6-cinchonine (Monatsh. 1898 19 473).Pure pseudocinchonine is proved t o be identical with cinchotine. I t melts at 265-2675' and thus agrees with the melting point of cinchotine found by Forst and Bijhringer (Abstr. 1881 620 and 830) and by Pum (Monatsh. 1895 16 70). The solubility of the base in alcohol is 1 pt. in 218.9 pts. while t h a t of cinchotine is 1 pt. in 221.5 pts. The hydrochloride (melting at 2 1 6 O ) the hydriodide (melting at 127') and the dihydriodide (melting at 258") are identical with the corresponding compounds of cinchotine. Cinchotine methiodide C,,H,,ON MeI foi ms hard white prisms melting at 244-246'. The hydrzodide of cinchotine methiodide CI,H,,ON,,RfeI,HI crystallises in compact yellow prisms which turn brown at 221" and decompose at 227-229". I t does not yield the methiodide on treatment with ammonia or sodium carbonate.Cinchotine when oxidised by potassium permanganate i n acid solution yields formic acid and a dark brown syrup which however contains no cinchotenine. Tho author's treatment of cinchonine dihydrochloride yields a much smaller proportion of the bases easily soluble in ether than Hesse obtained. The formation of a-isocinchonine in this manner is con- firmed by the author who also finds small quantities of p-isocin-ORGANIC CHEMISTRY. 963 chonine (probably formed by the action of the hydrochloric acid at the higher temperature on a-isocinchonine). Hesse’s work on the action of alcoholic potash on hydrochloro- cinchonine has also been repeated. a-Isocinchonine is separated from the mixture of three bases thus obtained by its solubility in ether.The two bases insoluble in ether are fractionated by crystallisation from alcohol. The one melts at 246” has a specific rotatory power when dissolved in two volumes of alcohol and one of chloroform ( p = 3) 215.51° dissolves in 120.4 pts. of water and is either cinchonine or more probably Cordier’s tautocinchonine (Zoc. c k ) . Its sulphate (C,,H,,ON,),,H,SO + 2H,O dissolves in 61.18 pts. of water. The other base agrees in its properties with Hesse’s apoisocinchonine and Lippmann and Fleissner’s allocinchonine with the exception that its sulphate has the composition (C1,H,,ON,),H,SO Similar results were obtained by hydrolysing hydrochlorocinchonine The proportion however of the bases + 4H,O. with alcoholic silver nitrate. insoluble in ether is in this case much larger.13,. H. P. Cocaine. By FRITZ GUNTHER (Chem. Centy. 1899 i 848; from Ber. phawn. Ges. 9 38-43. Compare Plmrm. Centv.-HalZe 39 1).- Mac-Lagan’s reaction for cocaine is useless for the valuation of the commercial article and is most probably dependent on the presence of another base for pure cocaine hydrochloride when dissolved in 1000 parts of water does not separate in a crystalline form on the addition of ammonia. A considerable quantity of a base which melts at 110-1 11’ and according to Salkomski acts physiologically like cocaine itself has been isolated from cocaine. Mixtures of this base with cocaine dissolve like a homogeneous compound and both bases crystallise from such solutions in apparently perfectly homo- geneous transparent prisms.From mixtures containing larger proportions of cocaine the bases may be separated directly although with difficulty by means of light petroleum; a better separation is effected by dissolving in alcohol neutralising with a solution of hydrogen chloride in alcohol and then precipitating the hydrochloride with ether. The mother liquor then contains a mixture of bases from which the one of higher melting point may be isolated by means of light petroleum. At ZOO this base requires 2500-3000 parts of water for solution (cocaine 704) and its solubility in other solvents is also less than that of cocaine. It is almost as strongly laevo- rotatory as cocaine forms an aurichloride and picrate which cannot be distinguished from those of cocaine even under the microscope and yields benzoic acid when decomposed by hydrochloric acid of sp. gr.1.1. The results of analysis agree with the composition of a methylcocaine and the compound is possibly an ethylbenzoylecgonine in which the hydrogen of the carboxyl group is replaced by ethyl. It is isomeric but not identical with cocethyline which also gives Mac- Lagan’s reaction. When treated with methylic alcohol the benzoyl- ecgonine prepared from this base yields methylbenzoylecgonine melting at 101’. The methylic alcohol however even after the most careful purification was found t o contain traces of ethylic alcohol964 ABSTRACTS OF CHEMICAL PAPERS. which easily condenses with benzoylecgonine for even when obtained from the purest cocaine benzoylecgonine was found also to yield bases of higher melting point when treated with this alcohol.It is probably for this reason too that the synthetically prepared commercial cocaine also gives MacLagan's reaction. A solution of 0.1 gram of cocaine hydrochloride in 85 C.C. of water should remain clear when 0.2 C.C. of ammonia solution is added. By HERBERT POMMEREHNE (Arch. Phccrm. 1899 237 475-480).-Damnscenine is an alkaloid which occurs in the outer coat of the seeds of Nigellca Damascena L. ; it has been isolated by Schneider (Inaug. Diss. Edangen 1890) who also prepared some of its salts. The author obtained it by digesting the uncrushed seeds for several days with 6 per cent. hydrochloric acid at 40-50"; the ex- tract was then made alkaline with sodium carbonate and shaken gently with light petroleum and the alkaloid removed from the petroleum solutiQn (which has a blue fluorescence) by shaking with 8 per cent.hydrochloric acid ; the acid extract was concentrated finally a t 40° and tho hydrochloride of the alkaloid purified by recry stallisation ; the seeds yielded 0.61 per cent. of the pure salt. The platinochloride (C,,Hl,03N),,H,PtCl melts and decomposes at 194-198" ; the auri- chloride is very unstable decomposing even in the dark The alkaloid contains two methoxyl groups and consequently has the formula C,H90N(OZC/le) ; it resembles methylic anthranilate (Walbaum this vol. i 630) closely in many of its properties.

QUAR- TAROLI (Gaxxetta 1899 29 ii 115-1 23).-Methylgranc~tyZamine C,H,,N obtained by reducing methylgranatonine oxime by means of sodium amalgam and acetic acid is a dense colourless liquid which has a faint basic odour and a t the ordinary pressure boils at 235-940' with slight decomposition but boils unchanged at 160-1'70" under 60 mm. pressure. It is very soluble in water and rapidly absorbs carbonic anhydride from the air with formation of a crystalline mass of carbamate.The hydrochloride forms a colourless deliquescent mass and the aurichloride C,H1,N,,3HAuC1 separates i n tufts of yellow needles melting with slight decomposition at 226O and soluble in boiling dilute hydrochloric acid ; the platinocldoyide is deposited in golden-yellow spangles which melt and decompose a t 260-261" and are very soluble in dilute hydrochloric acid even in the cold. The picrate crystallises from dilute alcohol in thin golden- yellow leaflets which melt with decomposition and evolution of gas at- 239-240".

The tcuri- chloride C,H1,N,,2HAuCl crystallises from dilute hydrochloric acid i n yellow needles melting with incipient decomposition a t 231-232" ; the platinochloride separates from dilute hydrochloric acid in bundles of needles melting and decomposing a t 265'.The picrate forms a microcrystalline powder which melts with strong decomposition a t 239-240". ~-Metl~ylyrc~nutyZ~henyZthioccLrbamide C,,H,,N,S crystal- lises from ethylic acetate in very slender colourless needles which melt a t 176' and are insoluble in water. When boiled for a long time with a 30 per cent caustic soda solu- tion or with an amylic alcoholic solution of sodium amyloxide methylgranatylamine is transformed into the q-compound. The relations between these two methylgranatylamines are the same as those existing between the two tropylamines obtained by Willstatter and Miiller (Abstr. 1898 i 492).

A methiodids is readily obtained which is insoluble in absolute alcohol but readily soluble in water ; the derived ammonium base is not so unstable as the corresponding compound of P-methyl- morphimethine. When morphimethirie hydrochloride is heated with a n alcoholic solution of sodium methoxide and methylic iodide the methiodide of p-ruethylmorphimet hine is obtained. A. L. Alkaloids from Yohimbehe Bark. By LEOPOLD SPIEQEL (Chem. Zeit. 1899,23 59-60 and 81-82 Compare ibid. 1896,20 970 and 1897 21 833; and Thorns Abstr.1898 i 455).-Yohimbehe bark contains a dye and two alkaloids yohimbine and yohimbinine. Yohim- bine C,,H,,O,N or C2aH300,N is a tertiary base and crystallises from dilute alcohol in glistening white needles and is readily soluble in alcohol ether chloroform acetone kc. but only sparingly in water. Its specific rotatory power in alcoholic solution is [aID 50.9'. When heated at 120-130° or when dissolved in absolute alcohol and evaporated t o dryness it appears to be converted into the anhydro- form C,,H,,O,N or C,,H,,O,N,. The hyclrochtorzde C,,H,,O,N,,€€Cl or C,,H,80,N,,HC1 is the only salt which has been obtained i n a crystalline form; i t melts at 295-300° but a t the same time undergoes decomposition. The methiodide is readily soluble in hot water but only sparingly in cold; it is usually deposited as a syrup which slowly crystallises. An acetyl derivative melting at 133" has been prepared and the action of hydrochloric hydriodic and nitric acids on the alkaloid has been studied but no definite products have been obtained. Oxidation with potassium dichromate and sulphuric acid yields carbonic an- hydride and formic acid whilst potassium permanganate in alkaline solution gives a small quantity of an acid melting at 85" and soluble in ether and two acids insoluble in ether; the one yohimbic acid C20H2406N2 is soluble and the other noryohinzbic acid ClSH2,07N2 insoluble in cold alcohol Although t h e alkaloid probably contains the aldehydo-group it was found impossible t o obtain an oxime or p hen y lhy drazone.ORGANIC CHEMISTRY. 961 Yohimbinine has not been obtained as yet in a state of purity; it can be freed from yohimbine by repeated solution in ebhylic aeetate from which the latter crystallises whilst gohimbinine remains in solution. It may be further purified by conversion into its hydriodide but is still probably not homogeneous since different specimens have very different melting points. Yohimbine yields a reduction product crystallising in glistening needles and decomposing at 106-108°. J. J. S. By &NILE BOUR- QUELOT and HENRI HERISSEY (J. Phcc~n2. 1899 [vi] 10,5-10. Com- pare this vol. i 652).-The pectin was obtained from the cynorrho- dons or f r u i t of the mild-rose (Rosa cccninu) either by maceration with water and precipitation with alcohol or by treatment in an autoclave heated to 110".

Its solutions are dextrorotatory [.ID + 165O and like those of other pectins are coagulated by pectase lime-water baryta- water caustic soda followed by hydrochloric acid or by neutral or basic lead acetate A precipitate is formed when its solution is saturated with magnesium or ammonium sulphate and with ferric chloride the pre- cipitate produced is coloured greenish-black due to the presence of a tannin-like substance. When pectinase is added to an aqueous solution of the pectin reducing substances are produced and the solution is no longer coagulated by pectase. When the coagulum obtained by adding pectase t o a solution of the pectin is treated with pectinase it almost entirely dissolves and reducing substances are produced. Pectin from the Fruit of the Wild-Rose. H. R. LE S. Action of Heat on Pepsin. By V. HARLAY (J. Phai-m. 1899 [vi] 10 105-108).-When pepsin dried a t 50° is heated at 100' for 34 hours its digestive action is not changed but its digestive power is perhaps slightly diminished. This confirms the statements of Schmidt (Cent?*. med. Wiss. 1876 29) and Salkomski (Yimhow's Archiv. 1880 81 552). The activity of a n aqueous solution of pepsin is diminished by heating it at 60" for half a n hour and the enzyme is destroyed at about 68'. By V. HARLAY (J.

The final product was an extremely light powder of whitish-grey colour readily soluble in water and having invertive power of a high order and by the lowest determina- tion 1.83 per cent. of ash. Various analyses indicate the average percentage composition of invertin to be C 44.54 ; H 6.52 ; N 6.1. The low percentage of carbon places invertin apart from the proteids; moreover it gives negative results with the majority of reagents for detecting proteids ; it however reacts faintly with copper sulphate Millon's reagent and the biuret test and more decisively with lead acetate alcohol phosphotungstic and phosphomolyhdic acids and the xanthoprotein test. There is a suggested resemblance to chitin inas- much as the analytical numbers are notl very different and after boiling for a few minutes with strong or slightly dilute hydrochloric acid invertin yields a reducing solution which when treated with phenyl- hydrazine gave a compound having the composition of phenylglucos- azone but melting at 198" instead of 205'.
