14 14 ABSTRACTS OF CHENICAL PAPERS.Organic Chemistry.Substitution in the Aliphatic Series. By V. MEBER and F.MULLER (J. pr. Chem. [2], 46, 161--188).-The continuation of theauthors' experiments on the halogenation of alkyl halides (this vol.,p. 5 7 i ) shows that the normal course of the reaction must be consideredto consist in the attachment of the newly-entering halogen atom tothe carbon atom adjacent to the one which carries the already-con-tained halogen atom, and not to the same carbon atom, as has hereto-fore been accepted.A repetition of Tawildarow's experiments (AnnnZen, 176,12) showedthat ethylidene bromide is almost exclusively produced when thebromination of ethyl bromide is effected at 200', whereas, as alreadystated (this vol., p. 577), ethylens bromide is the sole product whenthe reaction takes place at 100" in the presence of iron wire.Theboiling point of ethylidene bromide is 107-108", not 110-114", ashas been variously stated. The cause of the difference between thesereactions was thought to be the spontaneous change of ethylenebromide into ethylidene bromide a t 200" ; but when ethylene bromidewas heated in a sealed tube for 13 hours a t this temperature, it wasunchanged. Nor could ethylidene bromide be obtained from ethyl-m e bromide by heating it with hydrogen bromide, hydrobromicacid, or bromine. Two other explanations of the reaction a t 200"suggest theniselves : (1) the et'hylene bromide may, a t the momentof its formation, decompose into Tiny1 bromide and hydrogen bromide,which re-combine again to form ethylidene bromide ; (2) the changeof orientation is similar to such as occurs when toluene, for example,is brominated under different conditions.The bromination of ethylidene bromide, in the presence of iron, at'70-8Q0, yields 1 : 1 : 2-tribromethane.The chlorination of ethylidenechloride by antimony pentachloride in a reflux apparatus yields1 : 1 : 2-trichlorethane (b. p. 111-112"). Ethylene chloride is notattacked by antimony pentachloride in a sealed tube at 100'. Bothnormal propyl chloride and isopropyl chloride yield propylene chloride(b. p. 96-98?) when treated with antimony pentachloride a t normalpressure ; in the case of the former, the mixture requires heating at35-45', but the reaction takes place a t the ordinary temperature i nthe case of the latter.The following reactions confirm the authors' views, if the identifi-cation of the products be correct.The brorninations were effected bybromiric: in the presence of iron wire in a reflux apparatus at 50-60",and the chlorinations by antimony pentachloride a t the ordinary tem-perature.Butyl bromide (1-bromobutane) yields a, dibromide which boils a t15.7" and appears to be identical with pseudobutylene bromide(2 : 3-dibromobutanej, in which case a change of' orientation on thepart of the bromine atom in butyl bromide must occur. The authorshave been unable t o effect such a change without the substitution bORGANIC CHEMISTRY. 1415byornine. Swondary butyZ byomide (2-bromobutane, b.p. 90-93") alsoyields pseudobutylene bromide. Isobutyl bromide (1-bromo-2-mehhylpropane) yields some isobutylene hromide (1 : 2-dibromo-2-methylpropane, b. p. 148-149"), but higher brominated productspredominatc. Tertiary bu tyl bromide (2-hromo-2-methylpropane)also yields isobutylene bromide; tlhe reaction takes place at theordinary tern perature. and the production of higher brominated com-pounds is much smaller.The chlorination of normal butyl chloride produces a dichloridewhich boils a t 115-120", and appears to be 2 : 3-dichZorobutnne.Isobutyl chloride (1 -cliloro-2-methylpropane) and tertiary butylchloride (2-cbloro-2-methglpropane) both yield a dichloride whichboils a t 105-107", and appears to be 1-chloro-2 : 2-chloromethyl-propane ; its boiling pofnt agrees with that of d'oetreppe's dichloride(Jah~es',e~., 1332, 441), and, less exacflp, with that of the dichloridewhich CEconomides obtained hv the action of phosphoric chloride onisobutaldehyde (Abstr., lb'S1, 709).A. G. B.1 : 3-Dinitropropane. By F. KEPPLER and V. MEYER (Be?.., 25,26:38).--Tho authors have obtained small quantities of trimethylene-diamine platinochloricle by adding glacial acetic acid (40 grams) toan aqueous solution (I00 grams) of sodiodinitropropane (7 grams) ;sodium amalgam (500 grams of 2.5 per cent.) is now gradually added,and the temperature kept below 25" by cooling. The base is sepa-rated from the solution by E. Fischer's method (Abstr., 1884, 1289).Action of Silver Nitrite on Methylene Iodide.By A.RGSRANCJW ( B e y . , 25, 2635-~637).-Iodonitromethane was obtainedby V. Meyer (this vol., p. 5'15) by the action of silver nitrite onmethylene iodide. It, is prepared by adding silver nitrite ( 5 grams)t o a solution of methylene iodide (3 grams) in ether (20'c.c.):a trace of iodine is added, the whole carefully heated to boilingfor 45 minutes, and then allowed to remain for some hours :Itthe ordinary temperature. The ethereal solubion is filtered, and theresidue repeatedly extracted with srriall quantities of ether. Absolutealcohol (1 vol.) is now added to the ethereal solution (1 vol.), andsodioiodonitromethane (0.5-0-8 gram) precipitated by the additionof sodium ethoxide. The precipitate is collected, washed first witha mixture of ether (1 vol.) and absolute alcohol (1 vol.), then withether, and finally dried over sulphuric acid. The sodium derivativeis a slightly hygroscopic, white powder, which explodes OZI heatingand decomposes when kept.Its aqueous ~olution, acidified withsulphuric acid and extracted with ether, yields iodonitromethane asan oil of pungent odour, which very quickly decomposes, giving freeiodine.The sodium derivative may be diazotised, i f great care be employed,by the use of diazo-salts ; if excess of the latter be added, however,nitromethane derivatives, containing no iodine, are obtained. Slightlyless than the theoretical quantity of diazo-salt is therefore used.Sodioiodonitrometliane is dissolved in water (400 parts), and the ice-cold solution (50 parts) of the diazochloride added; tjhe precipitateW.J. P.5 c 1416 ABSTRACTS OF CHEMICAL PAPERS.is rapidly collected, washed with water, dissolved in a little ethylacetate, diluted with much alcohol, and precipitated with water. Theprecipitate should give a carmine solution with concentrated sulph-uric acid ; if a violet or blue colour is obtained, nitromethane deriva-tives have been produced. The precipitate, after filtration, is gene-rally pure.Iodoi~itromet haneazo be122 enw, NO,.CHI.N,P h, is obtained by thebbove method i n orange-yellow, microscopic needles. It melts a t110-112" with cotnplete decomposition, and, with concentrated sulph-uric acid, gives a carmine solution which soon turns grey.Iodoizitrometl~anetrzotcJl,iene closely resembles the preoeding sub-stance ; it melts a t 108-110".I f the diazotisation be carelessly performed in a concenti*ated solu-tion, cherry-red needles of azobenzenenitrornethaiie, or of parazo-toluen eni tromet hane, are respectively obtained.W. J. P.Silver and Copper Compounds of Acetylene. By E. H.KEISER (Awzer. Chern. .7., 14, 285-290) .--Acetylene was passedthrough amxnoniacal solutions of cuprous or silver salts respectively.The precipitate ww s washed by decantation in tall cylinders, fromwhich the stir had been reniored by a current of carbonic anhydride,using first' dilute ammonia, then water, and finally alcohol andether. It was then drained by the filter-pump and quickly trans-ferred to a vacuum desiccator shielded from the light; the silvercompound when diy, was snow-white.Specimens dried aft theordiriarg temperature contained from S9 31 to 89.44 per cent. of silver;a pieparation dried at 100" in a vacuum contained 89.62 per cent.silver. The formula, C,Ag2 requires 89.99 per cent. ; Miasnikoflt'sformula (Annulen, 118, 330), C,H,Ag,, requies 89-25 per cent. ofsilver.A weighed quantity exploded in a vacuum yielded but a very smallquantity of gas, and that was almost entirely absorbed by potash ;the residue consisted of carbon and finely divided silver. l h eformula C,Ag, may therefore be considered as established.The copper compound invariably contained free carbon ; moreoverthe voluminous precipitate was usually contaminated m ith the sub-stances in solution.The best result was obtained by the action ofacetylene on cuprous hydroxide suspended in water. The analysesindicate that Cn2C2 is the formula of' the compound. As in the caseof silver, no hydrogen was obtained on explosion.Compare Plimpton, Proc., lS92, 109. W. T.Action of Hydrogen Cyanide on Mercurous Salts. By ?.VTTALI (L'Orosi, 15, 186--192).-Cheynet ( J . Pha~m., 1892, 45b),Fouquet (Abstr., lS90, 229), and others have described experimentst o show that. in the reaction between hydrogen cyanide and calomel,mercury, mercuric cyanide, and hydrogen chloride are formed. Thisis further confirmed by the follo~ving observations :-On leaving pure ca Lome1 and very dilute h j drocyanic acid in con-tact for 24 hours, with occasional agitation, the calomel turns ashORGANIC CEEYISTRY.141 7colonred, and the solution becomes strongly acid. This is due tothe hrdrogen cyanide, as: on adding a, few drops to an alcoholic solu-ticn of Congo-red, i t turns blue; an alcoholic solution of phenol-phthaleiin reddened by soda is also decolorised.The presence of hydrochloric acid is shown by the insolubility ofthe silver nitrixto precipitate in nitric acid, and by the blzckeningof a silver dish in which a portion of the solution was placed togetherwith a little potassium nitiite-Mercuric chloride is absent from the solution, as no precipitateis obtained on adding excess of potash. The presenca of mercuric,cyanide in the solation is proved by expelling the free hydrogencyanide at a gentle heat, passing hydrogen sulphide, and testing theliquid for hydrogen cyanide.The absericc of mercuric chloride was proved by titrating the solu-tion with standard alkali i n presence of plienolphthalejin, before andafter treatment with hydrogen sulphide, thle acidity heinq actuallysomewhat lower in the latter case.S. I). A. A.Fulminuric and Deoxyfulminuric Acids. By P. SE~DEL (Ber.,25, 2756--d759).--Tn a former paper (this vol., p. W O ) , the authordescribed the formation of ethyl fulminuriite and of an acid obtainedfrom it by the action of boiling water or alcohol. This acid, d e w ! / -j*t/lminwic acid, C3H3N3O2, is best obtained by simply boiling theethereal salt with water, as, if alcohol is used, further decompositionoccurs with evolution of hjdrogen cyanide, and the product is lesspure.The acid is decomposed by hydrochloric acid at, 110-120". I tcould nol be reconverted into fulminuric acid by the action of nitricacid or iodine solution, Most, of its salts are coloured more orless. The alkali, silver, and lead salts are bright yellow, thecopper salt greenish-black, 1 he nickel salt pale-red, the ferrous saltviolet, and the ferric salt pale-orange. Tqhe silver salt, C3HZAgN302,when precipitated from slightly acid solutions, can be recrystallisedfrom boiling water, but if prepared from neutral or alkaline solutions,it always decomposes with separation of a pale-brown powder.If, in the preparation of ethyl fwlminurate, the heating is con-tinued for some time, a second ethyl fulniinumte is also formed.Thisis the principal produat if the rctction is carried out a t 100". Itci-ystallises with 1 mol. H,O in long, colourless needles, melts at155", and decomposes aEove 175". It is more soluble in alcoholthan its isomeride. Both salts are decomposed by hydrochoricacid a t 110-120", and by alcoholio potash. When heated with achloroform solutioii of ammonia, the ether of m. p. 133" yieldsammonium deoxyfulniinurate, whilst. the new ether gives fulminuy-amide, NH,-C3H203N,. T liis cryetallises i n colourless needles in-soluble in alcohol or ether, very sparingly soluble in boiling watei-,slightly more so in cold fioda; itamelts with) drcomposition above 250"Unlike isofulminuramide, iiidoes not give a double salt with arnmonia-cal copper solution.Pulminuric acid thus forms two series-o€ ethereal salts, of which theethyl salt melting a t 133" represents the oxy-salts, that melting at155" the nitrogen salts.L. T. T141 8 ABSTRACTS OF CHEMICAL PAPERS.Water of Crystallisation of Barium Thiocyanate. By J.TCHERNIAC (Bey., 25, 2627-2629) .-Barium thiocyanate is generallybtated t o crystallise with 2 mols. H30 ; the author finds, however, t h a tthe pure crystallised salt has t h e composition Ba(SCN), + :JH,O,;rnalogous to t h a t of' t h e crystallised thiocyanates of calcium and stron-tium. Commercial samples of the crystallised barium salt supposed t ocontain more thiocyanate than corresponds with 3 11101s. HzO aregenerally strongly contaminated with sodium salts.Pure anhydraus barium thiocyaiiate dissolves readily in absolutealcohol, and the solution 011 concentration in a vacuum deposits trans-parent needles ; these seem t o have the compositionBa(SCN), + 2EtOH.Similarly, anhydrous barium thiocyanatc (1 part) dissolves in drymethyl alcohol (L.3 parts) with development of heat ; on spontaneousevaporation of the solution, beautiful, lustrous, prismatic needlesseparate, having the composition Ba( SCN), + 2MeOHW.J. P.New Thiosulphates. By A. PURGOTTI (Gazxetta, 22,416-426).-Organic thiosulphates were prepared by Spring and Legras (Abstr.,1883, 47), who concluded tliat thiosulphates of saturated radicles ai ealoiie capable of existiiig. The author has, however, succeeded i npreparing thiosulphat es containing unsaiurated groups.Sodium allyZ thiosulphate, CH,:CH*CH,.S2OJNa + H,O, is .obtainedas follows :-Sodium thiosulphate and ailyl chloride, in niolecular pro-portion, are dissolved in water (2 vols.) and alcohol (1 vvl-) respec-tively.The solutions m e mixed, heated on t h e water-bath in areflax apparatus for 4-5 hours, and t h e product evaporated atl atemperature riot above 50". The residue is extracted with hotalcohol, and the solution on coricentratioii yields t h e salt in beautifullamin=, which are very soluble i n water and hot alrohol. I t saqueous s o h tion gives white precipitates with mercuric chloride andhilver nitrate solutious, and is decomposed on, boiling. When heatedwith hydrochloric acid, ally1 mercaptan is obtained.Sodium isqwopyl thiosu&Aute, CHMea-Sz@3Na + 3H20, prepared by amethod analogous to that above described, forins crystalline scaleswhich are very soluble in water and hot alcohol, sparingly so in coldalcohol.The aqueous solution gives white precipitates with silvern h a t e , and mercuric chloride, and, when concentrated, with bariumchloride. The buriurre salt, (CHhle,S,O,),Ba i- 2H,O, separates fromits hot aqueous solution in splendid needles o r Iamiuae.Sodium eth yleibe thioszilphate, C,H,( SL03Na),, prepared fromtthylene chloride, crptallises in scales very soluble in water and inboiling alcohol. The barium salt crystallises in large, 111s trow plates.Sodiim hydroxy et hy 1 thiosulphate, C2H4(0 H) *X2C),Na, is obtained byt h e action of ethylene chlorhydrin on sodium thiosulphate.It c i y -tallises in small, biilliant needles, and is very soluble in hot waterand alcohol. I t s aqueous solution is decomposed b y boiling, andgives a white precipitate with mercuric chloride ; with silver nitrated u t i o n no precipitate is obtained iii t h e cold, but on warming t h eiher salt separates in crystalline lamineORGANIC CHEMISTRY. 141 9Barium acetothiosulpphate, CH,< E%y>Ba + 2Rz0, prepared from- -sodium thiosulphate and sodium chloracetate, forms crystalline crustsand is fairly soluble in hot water; the solution decomposes slowly onboiling. When treated with hydrochloric acid, it yields thioglycollicacid. The sodium salt is very deliquescent, and will not crystallise.The potassium salt forms minute needles which are very soluble inwater.The siloer salt forms a white precipitate which alters whenkept in the dark.Sodium ei-hyl acetothiosu7phate, COOEt.CH2*Sa03Na, is obtained byheating ethyl monochloracetate (24 grams) dissolved in alcohol(50 grams) with sodium thiosulphate (50 grams) dissolved in water(80 grams). I t crgstallises from hot alcohol in beautiful monosym-metric crystals, and is very soluble in water, less so in alcohol. Theaqueous sollition gives white precipitates with mercuric chloride andsilver nitrate. The dry salt, on distillation, yields ethyl dithiogly-collate. w. J. P.Optical Properties of Dulcitol and its Derivatives. By A.W. CROSSLEY (Bey., 25, 2564--2565).-Diacetgldulcitol and tetr-acetyldulcitol are both optically inactive ; the specimens stated byBoucharclat t o be active were probably impure.This fact is of im-portance in the application of the theory of asymmetric carbon atomst o the compounds of the sugar group. J. B. T.Disappearance of the Multirotztion of Sugars in Ammonia-cal Solution. By C. SCHULZE and B. TOLLENS ( A n t d e n , 271, 49-54).-Solntions of dextrose and of other sugars in concentrated am-iuonia do not show multirotation, the rotatory power of' the freshlyprepared solution being practically constant and, as a rule, rather lessthan that ultimately attained in aqueous solution.The specific rotatory power of a solution of dextrose in ammonia ofsp. gr.0.924 is [a]n = 49-82" immediately after solution, that of asimilar solution of xylose [ a ] D = 14-82", and that of a similar solutionof maltose hydrate [ a ] D = 126.1"; in all three cases, the specificrotatory power is a little lower than the constant value determinedin aqueous solution. On keeping the ammoniacal solutions, thespecitic rotatory power gradually diminishes; in the case of thexylose solution, for example, it was found to be [aID = 5.67"at the end of the third, and [&ID = -5.85" at the end of the fifthday.The specific rotatory power of a solution of dextrose hydratle in5.7 per cent. ammonia is [ a ] D = 47.241" about 8 minutes after solutionwhen weaker ammonia is used, the specific rotatory power of thefreshly prepared solutions gradually increases unti 1, when 0.1 per cent.ammonia is employed, the specitic rotatory power becomes normal.ahen 0.01 per cent.ammonia has a very marked influence on the biro-tsition of sugars ; the specific rotatory power of a solution of dextrosehydrate in 0.01 per cent. ammonia is 49.98" 8 minutes after solution,and becomes normal a t the end of 12-15 minut,es longer. Whenthe concentration of t h e ammonia falls to 0.001 per cent., the effec14 20 Al3STRAPTS OF CHEMIOAII PAPERS.of the solvent on the birotation of dextrose can no longer be observedwith certainty.As a result of the examination of the following compou1idrJ:-dextrose hydrate, xylose, arabinose, galactose, rhamnose, maltosehydrate, levulose, half rotatory lactose, C,2H220,,, and normal lactose,C,,H,,OI1 + H20, the authors find that the values for the epecificrotatory power in 0.1 per cent,.ammonia, determined a few minutesafter solution, are practically identical wiih those obtained withaqueous solutions after 20 hours ; only in the case of galactose did thedifference between the two values amomit to almost 1".The rotatory power of cane sugar is not influenced by 0.1 per cent,ammonia. F. S. I(.Xylose and its Optical Properties. By C, SCHULZE and B.TOLLENS (Annulen, 271, 40-46).- A large quantity of xylose wasprepared from chopped wheat-straw by a method similar to that em-ployed by Bertraiid (this vol., p. 28) ; the yield of pure, colourlessxylose amounted to about 5 per cent. of the air-dried straw.Therotatory power of the xylose was then determined in aqueous solu-t8ions of different concentration, which had been kept for 20-24hours ; the results of the observations are given in a table and arealso mapped on a chart. It was found that the specific rotatorypower increases continuousIy from 18.425" to 23.702" as the concen-tration increases from 9.706 t o 61.737 per cent. For solutions con-taining up to 34.355 per cent., the specific rotatory power may becalculated by the formula [a]D = 18.095 + OOti986P (P = percentageof xylose in solution), and is represented on the chart by a straightline; for solutions containing from 34355 to 61,737 per cent., thespecific rotatory power may be calculated by the formula [aIn =23.089 - 0.1827P + 0.00312P2, and is represented on the chart bya straight line, bent slightly upwards with respect to the first line.The above observations were made a t 20", but special experimentsshowed that the specific rotatory power is practically constant between15" and 20", although above 20' the change begins to be appreciable.The Pentosans of Wooay Vegetable Fibre.By C. SCHULZEarid B. TOLLENS (Annulen, 271, 55-61 ; compare Abstr., 1889,480).-The products of hydrolysis of malt which has h e n used for brewingare xylose and a comparatively small quantity of arabinose; thepresence of mannose could not be detected. Both xylose and arabin-me are only slowly decomposed by boiling 10 per cent, sulphuricacid, the former being rather lem stable than the latter.Quincejuice yields xylose on hydrolysis, and probably alRo dextrose (compareBauer, this vol., p. 128) ; luffa gives about I per cent-of pure xylose.Multirotation of Rhamnose and of the Saccharins. By W.SCHNELLE and B. TOLLENS (Annulen, 271,61--67).-A systematic ex-amination of 10 per cent. aqueous solutions of rhamnose, C6H,,0, +H20, at 20" has shown that the specific rotatory power of the sugaris about [ a ] ~ = -3.21" immediately after solution, this valuegradually becoming less until, after about 9$ minutes, the solutjo3 isF.. S. K.F. S. KORGANIC OEEMISTRY. 142 Ioptically inactive ; the specific rotatory power then gradually in-creases, and after 66 minutes, a constant value of [ a ] , = 8-56", or[RID = 9-43' for anhydrous rhamnose, is attained.Up to about40 per cent., the concentration cjf the solution has no appreciable effect011 the specific rotatory power ; an increase of temperature diminishesthe specific rotatory power, the diminution being about 0.035" between6" and 20".Saccharin prepared from dextrose by Kiliani's metho*l also showsmultirotation ; immediately after solution, the specific rotatory poweris [a]D = 94.2" at 20°, but this value falls to [ a ] D =88*7O aftera lapse of 11 days ; the specific rotatory power also decreases as thetemperature rises.The specific rotatory power OF isosiccharin, from lactose, is [a]D =62.97", that of metasaxcharin [alD = -46.83" ; these two compoundsdo not show multirotation. F. S. K.Production of Acetic Acid from Cellulose and other Carbo-hydrates ; Lignocellulose and FerY;ic Ferricyanide.By J. F.V. ISAAC (Ghem. News, 66,3940; .-If cotton cellulose and hydrocellu-lose, jute-fibre and pine wood, and sugar are acted on by alkali hydr-oxides wit*hin limits of temperature between 120" and 150" and 250" and350" they yield from 7 to 10 per cent. of their weight of acetic acid ; atthe lower temperature, the qnantity is considerable, and is increasedby prolonging the action and by the addition of weak oxidising agents ;potassium hydroxide produces more acetic acid than sodium hydroxide.Jute fibre absorbs even as much as 80 per cent. of its weight offerric ferricynnide from solutions obtained by adding potassiumferricyanide t,o ferric chloride, at the same time converting it intoPrussian blue.Freezing point methods of ascertaining molecular weights withBeckmann's apparatus, owing apparently t o dissociation, cannot beused for solutions of cellulose acetate, benzoate, and nitrate in aceticaci'd .D A. L.Urea Oxdate, By P. IE. KIRKALDY (Ohem.

D. A. L.Propylcarbamide and Unsymmetrical Dipropylcarbwmide ,By F. CHANCEL (Conzpt. rend., 115, 242-243).-Propylcnrbamide isreadily obtained by the action of ammonia on the mixture of pyopyliodide and propyl isocyanate resulting froni the action of silrer iso-cyanate on prop.yl iodide.It can be prepared even more easilg bymerely mixing aqueous solutions of propylamine sulpha te and potas-sium isocyanate ; part of the potassium sulphate separates a t once,and the remainder can be precipitated by alcohol. The product isidentical in both cases. It crystallises in long needles which melt a t1(J7", dissolve readily in water or alcohol, and are neutral to litmus.When heated with hydrochloric a.cid in sealed tubes at 160", propyl14-32 ABSTRAOTS OF UHEMICAL PAPERS.carbamide yields carbonic anhydride, propylamine hydrochloride, andammonium chloride. The nitrate aud oxalate are very soluble in water,b u t they do not crystallise well from aqueous solutions ; they are alsovery soluble in alcohol, from which the nitrate crptallises in slenderneedles.Unsymmetrical dipropylcarb2niide, NH2*CO*NPr2, is obtained bymixing aqueous solutions of dipropylamine sulphate and potassiumisocyanate. It is very soluble in water and alcohol, and crysta,llisesfrom the latter in white needles which melt a t 57" ; it is neutral tolitmus. The normal oxalate is very soluble in water, from which itcryetallises readily in needles ; it is acid to litmus.The nitrate formsan uncrystallisable syrup.New Method of Preparing Dimethylethylsulphine and MethylEthyl Sulphide. By G. CABRAKA (Gazzetta, 22, 408-415).--Tri-methylsulphine may be prepared by heating methyl sulphide (10 parts)with dry iodine (1 part) in a sealed tube at 110-120" for 24 hours ;the reaction proceeds more slowly a t 110". No hydrogen iodide isproduced.The product is dissolved in water and separated from un-attacked methyl sulphide ; the aqueous solution, after extraction withcarbon bisulphide, is treated with silver chloride, filtered, evaporatedon the water-bath, and trimethylsulphine platinochloride precipitahedfrom the alcoholic ethereal solution by the addition of platinumtetrachloride.A mixture (10 parts) of ethyl and methjl sulphides in molecularproportion was heated with iodine (1 part) in a sealed tube a t120-140" for 24 hours. By treating the product as above, dimethyl-uthylsulphine platinochloride and trimethylsulphine platinochloridewere obt'ained. The liquid separated from the aqueous solution con-tained a conbiderable proportion of methyl ethyl sulphide, which maybe obtained pure by fractional distillation.A mixhure of amyl and ethyl sulphides, when heated with iodine at130-140", and subsequently treated as above, yields only triethyl-aulphine platinochloride.Hence, it seems that there is a tendencytowards the formation of a sulphine containing as few carbon atomsas possible.If the additive product of methyl sulphide and bromine, MezSBr,,obtained by Cahours ( A n n a h , 132, 8 8 ~ , is heated with iodine at113--120", and afterwards treated as above, it yields trimethylsulphineplatinochloride.

W. J. P.Preparation and Estimation of Thiocyanacetone.Ry J.TCHERNrAC (Ber., 25, 2621--21-;26).--The author bas devised athermonnalytical method of estimating thiocyanacetone. The heatdeveloped on treating an aqueous solution of this substance withnormal sodium carbonate solution is directly proportional to theamount of the acetone present. The estimation is carried out in aBeckmann's apparatus for cryoscopic determinations, and is per-formed in much the same way as those determinations.The author prepares thiocyanacetone as follows :-EquivalentquRntities of chloracetone and crystallised barium thiocyannte areshaken together in a thick flask containing some glass marbles tobreak up the mass. The odour of chloracetone disappears after6-15 hours, when the reaction is complete.The product is extractedthrice with ether, the ethereal solution washed with a little water,and distilled at 40-50°. A slow stream of carbonic anhydride ispassed through the residue, kept under a low atmospheric pi'essure a t40-50" ; after evaporating off the water by this means, the residualoil contains about 98-18 per cent. of thiocyanacetone. It can befurther purified by shaking its saturated aqueous solution in thecold with animal charcoal (I per cent.) ; on extracting with ether,and evaporating the ethereal solution in a vacuum over sulphuric acid,a product containing 99.1 8 per cent. of thiocyanacetone is obtained.On distilling the aqueous solution of this under reduced pressure init stream of carbonic anhydride at 40-50°, and evaporating theethereal extract of the distillate in a vacuum over sulphuric acid, astill purer product is got.Thiocyanacetone, prepared as above, is a slightly coloured, stronglyrefractive oil, which darkens very slowly when kept in the dark.Its sp.gr. is 1.200 a t Oo/4O and 1.180 a t 20"/4".

HOLT (Be?-., 25, 2667--2671).--Tn a previous paper (thisvol., p. 812), the author has shown t)hat the bromo- and iodo-additiveproducts of behenolic acid are reconverted into behenolic acid by the,action o€ sodium amalgam, and are therefore to be considered asderivatives of brassidic acid, The present paper deals with thechloro-additive compounds.Dichlorobs.assidic Acid.--TVhen a chloroform solution of behenolicacid cooled with ice arid salt is treated with chlorine, 1 mol.ofchlorine is absorbed, and a viscid, pale-yellow oil is obtained, whichgives numbers corresponding with the formula of dichlorobrassidicacid. On treating this product wit'h sodium amalgam, it is found tobe a mixture, for it yields a small quantity of behenolic acid, an oilfree from chlorine, and a small quantity of behenic acid (m. p. 76").Dichlorobrassidic acid is, however, easily obtained in a state of purityby boiling the corresponding dibromo-componnd with mercuricchloride (1 mol.) in alcoholic solution.It is a viscid, bright yellowoil, is somewhat sparingly soluble in cold alcohol, easily so in warmalcohol and other organic solvents, and when treated with sodium am&gam yields 90 per cent. of the theoretical quantity of behenolic acid.The tetrachloride of behenolic acid cannot be obtained by the directaction of chlorine on behenolic acid ; but is easily obtained by boilingthe tetrabromide with mercuric chloride (3 mols.). It, separates fromalcohol as an oil, but soon solidifies in beautiful, long needles ; it meltsa t 41", and when treated with sodium amalgam is entirely convertedinto behenolic acid.Behenolic acid dissolves in pure concentrated sulphuric acid to apale-brown, clear solution,, which yields a small quantity of pre-cipitate after R time, and darkens.By pouring the product intowater, a Eydroxy-acid, C22Ha,0,.0H, is obtained ; this crystal-lises from alcohol R S a white powder, melts at 83", and is identicalwith the acid obtained by the action of concentrated hydrochloricacid on behenolic acid.BehenoZic anilidp, C&lH3g*CO*h'HPh, is obtained by heatingbehenolic acid with excess of aniline for four hours a t 220°, andextracting the product witlh very dilute hydrochloric acid. It sepa-rates from alcohol as a colourless, voluminous, crystalline mass, meltsat 73", is easily resolved into its components by halogen acids, is fairlystable towards potash, and when boiled with alcoholic potash for10 hours yields aniline and hehenolic acid.Behenolin phelz?/Zhyclrazide, C,,H3g*CO*NH*NHPh, is obtained bywarming molecular proportions of behenolic acid and pbenylhgdrazineat 140-145'.It crystallises from alcohol in small, colourlessneedles, melts a t 86*5", is somewhat sparingly soluble in cold alcohol,gives a mirror with alcoholic ammoniacal silver nitrate, and dissolvesin concentrated sulphuric acid to a colourless solution, which turnsdark-red on the addition of potassium dichromate.

C. R.Constitution of Ethyl Sodaoetoacetate. By A. MICHAEL( J . pr. Chew,. [2], 46,189-208).- The author continues his criticism(this vol., p. 1178) of Nef's paper on ethyl acetoacetate (this vol.,p. 140). From the fact t h a t ethyl copper acetoacetate a n d ethyl leadacetoacetate do not react so easily with ethyl iodide as ethyl sodaceto-acetate does, Yef argues that there is no direct substitution of thesodium by the ethyl in the latter reaction, and in support of this hequotes what he supposes to be facts concerning the greater ease withwhich copper, lead, or mercury phenol, and the salts of these metals,are attacked by ethyl iodide than are the corresponding sodiumcompounds. The author asserts that this difference is entirelyimaginary.According to Nef 's hypothesis, an iiikermediate con-pound containing the group :CI*ONa is fmmed when ethyl iodide andethyl sodacetoacetate react. The iodine atom i n this group is thensupposed to leave the molecule in company with the hydrogen atomof the next group ; the group CONa remains, and subsequently reactswith the evolved hydrogen iodide, forming the group COH. This iscontrary to all our knowledge concerning compounds which containboth hydroxyl and halogen atoms attached to the same carbon atom ;such compounds lose the hydroxvl hydrogen and halogen as hjdrogenhalide with the greatest ease, and the Sam18 course of' change maysurely be expected when sodoxyl replaces hydroxyl. Nor can Nef'sexperiments be held to fully confirm his oonclusion that the morenegative the group introduced into the niolecule of ethyl acetoacetatethe layger will be t'he proportion of di-substitution product formedin subsequent reactions (this vol., p.141). For inasmuch as thereaction between ethyl chlorocarbonate and ethyl sodacetoacetate re-sults in the production of '7parts of di- and 2 parts of mono-derivative(ethyl acetj lmalonate and ethyl acetylcarbintricarboxylate, this vol.,p. 14.5), acetyl must be, according to Nef, more negative than thegroup COOEt, yet the reaction between ethyl sodacetoacetate andacetic chloride yields niueh ethyl acetjlacetoacetate and only a littleethyl diacetylacetoacetate (e-thyl triacetylacetate, this vol., p.145).The statement that ethyl ethylacetoacetate is not reduced by treat-ment with sodium in ethereal solution is incorrect ; the author foundthat the quantity of hydrogen evolved by the reaction is f a r short oORGAN10 CHEMISTRY. 1429the theoretical quantity, and when the liquid was subsequentlyexamined undoubted evidence of the presence of unsaturated acidswas obtained.These are the main points of the critical portiori of the paper. Thetheoretical considerations with mhich it concludes can only be appre-ciated by reference to the original.Action of Phenylhydrazine and of Hydroxylamine on De-hydrodiacetyllevulinic Acid. By G.

The yield is 103 grams, or 87 per cent.of the theoretical.Hydrazodicarbonamide seems n o t to be acted on by moderately con-centrated (1 : 1) potash in the cold; it is soluble i n warm potash,yielding as a rule a turbid solution, from which i t is pvecipitated un-changed on adding water. Azodicarbonamide (Zoc. cit.) can be easilgobtained by triturating the finely-di vidpd hydrazo-compound (10grams) with water (1 litre), heating to boiling, and then adding asdution of potassium dichromate (16 gra,ms) in water (60 c.c.) andsulphuric acid (15 c.c.) ; an eneygetic reaction takes place, the mix-ture darkens in colour, and the whole of the hydrazo-compoundpasses into solution.The solution is then cooled t o 0" as quickly aspossible, and the azodicarbonamide, which is precipitated as anorange-red powder, separated by iilrration, washed, and dried. Theyield is 70 per cent. (7 grams). Azodicarbonamide is decomposed byboiling sodium carbonat,e, yieIding nitrogen, carbonic anhydride,ammonia, and hydrazodi csrbonamicle.Potmrium azodicarboayhte, COOK*N:N*COOK, is formed withevolution of ammonia when azodicarbonamide i s triturated with ice-cold, moderately concentrated (1 : 1) potash. It is a yellow powder.,stable in the air, but decompnsed by water, in which it dissolves freelywith a yellow coloration.The dry substance decomposes slo wly a t1 OO", and explodes at a slightly higher temperature, yielding in bothcases potasRium caybonate, nitrogen, and carbonic oxide. It givesLiebermann's reaction, but the colorations are much less intense thanin the case of a nitroso-compound.l?a~-izrm azodicarbozyltrte, C2N?O4Ba, can be obtained by adding asoliltion of barium chloride, which has been saturated with bariumhydroxide, to R solution of the potassium s a l t ; it is a light yellowpowder insoluble in water, by which it is quickly decomposed.When potassium azodicarbonamide is treated with water at theordinary temperature, a vigorous evolution of nitrogen and carbonicanhydride takes place and a yellow solution is obtained ; after a veryshort time, the solution becomes colourless, and then contains hydr-nzitle and potassium carbonate.The decomposition of the bariumFalt takes place more slowly, b u t in a similar manner. The aqueoussoliition of the potassium salt is much more stable in presence ofcaustic alkalis, and under these conditions the yellow colour does notdisappear for some minutes even on boiling.A l l attempts to prepare diimide, NH:NH, from the salts of azodi-carboxylic acid were unsiiccessful, and it would seem that this com-pouiid is iucapabie of existence.

CONRAD (Be?-., 25, 2446-2448).-Theformation of this acid, by the action of ferrous sulphate on tartaricacid, is not due, as Ballo thought (Abstr., 1889, 693), to t h e reduc-ing action of the former, but rather to its dehydrating action (cf.Scheibler, khis vol., p.1180). Equal weights of tartaric acid andferrous sulphate were dissolved in twice the weight of water, andheated on the water-bath for 15 hours. The solution was filtered,concentrated to a small bulk, and extracted with alcohol. The extractwas neutralised with barium carbonate, filtered, evaporated to dryness,dissolved i n water, and converted, by meaiis of potassium carbonate,into the potassium salt of isarabic acid. The concenti.ated solntion ofthe la?ter, when treated with excess of acetic acid and alcohol, gavea precipitate of potfissiurn hydrogen tartrate, and potassium hydro-gen isarabate remained in solution.If, however, the latter is pre-cipitated with lead acetate, the precipitate decomposed with hydrogeORGANIC CHEMISTRY. 1433sulphide, and the solution filtered and concentrmed, tartaric acidcrystnllisos o u t ; if the aqueous solution of the potassium saltis heated for a few minutes onlj- with aqueous potash, and thenacidified with acetic wid, potaqsium hydrogen tartrate separates out.This very ready conversion of isarabic into tartaric acid renders itimprobable tliat the former is formed from the latter by reduction.C.

Molecular weight determinations by the boilingpoint method confirm the above formula. The compound is soluble illether, benzene, alcohol, and water ; on heating with dilute sulphuricacid, i t is resolved into its constituents. The isomeric furfuraldoxime(m. p. 49-56') described by Bderheimer consists of a mixture of fur-fursynaldoxime and antialdoxime, as is shown by its action on phenylcyanate. With orthotolyl or paratolyl cyanate, carbotoluidofurfursyn-aidoximes (see below) are formed, the anti-derivatives being appa-rently incapable of separate existence.Benzantialdoxime, on treatment with paratolyl cyanate in etherealor benzene solation, both a t ordinary temperatures and on warnling,yields carboparatotuidobelzzantialdoxime, C6H5* G *H, whichC,H4Me-NH*C0 0-Ncrystallises from benzene in colourless needles and melts at 121".Thecorresponding benssynnldoxime derivative melts at 74-76', and onrecry stallisation from ether is converted into a compound which meltsat 88-89".J?urfurantialdoxime is partially converted into the synaldoxime bythe actisn of acetic anhydride; on treatment with methyl iodide inthe manner above described and distilling with steam, a product isisolated which boils at 150-168", and appears to be an impure methylether ; methylfurfursynaldoxime is also produced in considerablequantity.'rhiophenaildoxiines.-Thiophensynaldoxime melts a t 133 O , instead of128", as stated by V.Meyer.

B. T.Dipropargyl and Benzene. By J. W. BRCHL (Ber., 25, 2638-2646).-Up to the present, the molecular heat of combustion of di-propargyl (854-883 Gal.) has not been accarately determined, but iscertainly much greater than that of benzene (784-788 Cal.) ; this isin harmony with the chemical behnviour of the two substances whichindicates that the intramolecular tension is greater in dipropai-gylthan in benzene. The author has already conjectured (Abstr., 1891,630) that the differences between the molecular refractions and dis-persions of these two hydrocarbons are in the opposite sense to thO R ~ A L ~ 10 ChEMISTRT. 1437differences between the heats of combustion ; this is now shown to bethe case.The dipropargyl employed was purified by distillation in aslow current of a i r in a vacuum a t the ordinary temperature; avery slight resinous residue was left, and the hydrocarbon wasobtained as a colourless liquid which turned yellow in a few hours. Themolecnlnr refraction of dipropargyl (25.74 for sodium light) I S con-siderably less than that of benzene (26*13), and agrees remarkablywell w i t h the calculated value considering the great difficulty of pre-serving the hydrocarbon unchanged during the measurement. Thepresence of two acetylenic bonds in dipropargyl is thus clearlyindicated, and the spectrometricnl data are in complete accord withthe chemical behaviour of the substance. W.J.

NEE' (Annalen, 270, 267-335).-Although carbonic oxide is an unsaturated compound, it is, relatively,very inert ; it does not combine with iodine, or with halogen acids at200"; it absorbs chlorine only very slowly in diffusad light, andeven in direct sunlight it is only very slowly and incompletelyacted on by bromine. If, in the place of the oxygen atom in carb-onic oxide, some less negative group were introduced, a substancewould be obtained which would doubtless possess greater chemicalactivity than carbonic oxide ; such substances are, possibly, hydro-gen cyanide and its salts, and the isocyanides or carbylamines.Starting from this assumption, the author has studied the proper-ties of some isocyanides ; he claims to have proved that they containbivalent carbon, and are represented by the general formula R*N:C ;he is also of opinion that the corstitution of hydrogen cyanide isvery probably expressed by the formula H-N:C.The following arethe grounds on which the existence of a bivalent carbon atom in theisocyanides is assumed :-The isocyanides combine with halogens andwith halogen acids, even at -15", wit,h development of great heat,yielding products of the constitution R*N:CX, and ( R.N:CHX),,HXrespectively. They are readily converted into thiocarbimides bysulphur a t 13O0, and into thiamides by hydrogen sulphide a t 100".They combine with carhonyl chloride a t - 15" yielding compoundsof the general formula R*N:CCl*CO*CCl:N*R, and with acetic chlor-ide at 100" they form imidochlorides of pyruvic acid of the generalformula R*N:CClAc.They combine with primary arnines a t180-220", yielding formamidine derivatives of the comtitu tionR-N:CH.NH R'. Orthotolyl isocyanide combines directly with berzoicchloride a t 100" yielding the compound described below.Phenyl isocyanide, PhN:C, prepared by treating aniline Kith chloro-form and alcoholic potash, freed from aniline and diphenylform-amidine by shaking its ethereal solution with dilute hydrochloricacid, and purified by distillation, is a colourless oil, which soon turnsgreenish-yellow on keeping. It boils a t 6 4 O under a pressure of20 mm., a t 71" under a pressure of 30 mm., and at 78" under a pres-sure of 40 mm., leaving a small quantity of a blue residue ; the dis-tillate is colourless, but soon turns blue, and then gradually darkens ;after some time, deep purple-red needles are deposited, and, on longkeeping, the whole is converted into it solid resin, which is probablya polymeride.Phenyl isocyanide is reduced by sodium and boilingamyl alcohol, being reconverted into methylaniline ; when treated withglacial acetic acid a t the ordinary temperature, it yields formanilideand acetic anhydride, together with considerable quantities of acet-anilide. It reacts violently with anhydrous formic acid, even a tO", yielding formanilide and carbonic oxide, the latter being prob-ably generated by the decomposition of the formic anhydride whichis doubtless produced as an intermediate product ; with anhydrousoxalic acid a t 0", it yields formanilide, carbonic oxide, and carbonic:anhydride, a reaction wliicli seems t o show that oxalic anhydride isalso incapable of existence.When heated a t 130" with an alcoholicsolution of sodium ethoxide, it yields a large quantity of diphenyl-formamidine; it reacts with silver oxide and with mercuric oxidORGANIC CHEMISTRY. 1439with explosive violence, but, when diluted with ether and thenwarmed with mercuric oxide a t 40-50", it gives traces of pheriylcyanate, the oxide being reduced to metal.Xsocyanophenyl diehloride (phen?/limidoca,.Eonyl chloride), NPh:CCI,,is formed when chlorine is passed into a well-cooled chloroform solutionof phenyl isocyanide until the colour of the solution suddenly changesfrom blue to yellow.It is a colourless oil, boils a t 209-210"(thermometer entirely in vapour), and has a very irritating action onthe eyes. When heated with glacial acetic acid, i t yields acetaniiide ;with water, symmetrical diphenylcarbamide ; with silver oxide, phenylcyanate ; with alcohol, phenylurethane ; with aniline, a-triphenyl-gtianidirie hydrochloride. The isocyanophenyl dichloride, previouslydescribed by Sell and Zierold (Ber., 7, 1228), is a mixture of thecompound described above with a chloro-derivative, C6H4C1-N:CC1,.Phenyl isocyariide combines with bromine (1 mol.) in cold chloro-form solution, yielding a yellow, unstable oil, which cannot be dis-tilled, but which has, doubtless, tlhe constitution NPh:CBr, ; it alsocombines with iodine (1 rnol.) in carbon bisuiphide solution to forman oily product.Mesoznidide imidochloride (phel?,2/lamidomeso~al~c chloride),NPh: C C 1.C 0.C CLN Ph,can be obtained by treating phenjl isocyanide with carbonyl chloridea t -2200, and then :thowing the temperature of the mixture t o riseslowly ; it is a thick, yellow, hygroscopic oil, boils a t 145-152" undera pressure of 15-20 mm., with slight decomposition, and is decom-posed by cold 10 per cent.soda, yielding a considerable quantity ofp h en yl isocyanide.Mesoxanilide alcoholate, NPh:C(OH)-C(0H) (OEt)*C(OH):NPh, isformed when the imidochloride is treated with water, and t8he solidhydrate obtairied in t h i s way recrystallised from boiling alcohol.

It combines with carbon bisulphide at 130°, yieldingorthotolylthiocarbimide ; when heated with an alcoholic solution ofhpdrogek sulphide at 190", it gives thioformorthotoluidine (m.p.100-101").Isoqanorthotolyl dichloride (tolylirnidocarbonyl chloride),C6H4Me.E:CC12,is formed when di*y chlorine i s passed into a well-cooled chloroformfiolution of orthotolyl isocj-anide ; it is a colourless oil, and boils at2 14-215" (compare Lachunnn, Bey., 12, 1349) ; when treated withorthotoluidine, it is converted into tri-orthotoly Iguanidine hydro-chloride.Mesoxatoluidide 11 ydrnte,C,H,Me*N:C (OH).C(OH),*C (OH) :N.C,H,Me,can be obtained loy treating orthotolyl isocyanide with carbonjlchloride i n the cold, and decomposing the product with water; i tcrjstallises from hot water, i n which it is only very sparingly soluble,in colourless needles, turns yellow at loo", ant1 melts at 127-151"wibh decomposition.It turns blue litrrius rrd, is soluble in dilutesodium carbonate, and i s decomposed into i t s constit,uents by boilinganhydrous benzene, combination taking place again, to a certaiiiextent, on cooling the solution.Pyyucic orfhotohidide, C6H4Me-N:CAc*OH, seems to be produced,together with formoi*tbotoluidide, when orthotolyl isocyanide isw,trmed with acetic chloride for five minutes on the water-bath, andthe unstable imidochloride obtained in tliis way S ~ O W ~ J poured into 1442 AR5TRACTS OF OHEMIOAL PAPERS.large volume of water ; the aqueous Polution is extracted with ether;t h e extract shaken with soda, the alkaline liquid acidified, extractedwith ether, and the ethereal solution evapgrated.The compoundobtained in this way crjstallises in hexagonal plates, melts at 62", andis very readily solnhle in water; i t is probably a hydrate of t h econstitution C,H,Me*N:C(OK)*CMe(OH),, as, when treated withcalciuni chloride in ethereal ssolntion, i t is transformed into a crystal-line compound, meiting at P77", which is probably R polymeride ; thelatter is insoluble in ether and water, but readily soluble in hotalcohol and in dilnte soda, from which it is reprecipitated by acids.Benzo y lform ort hotoluidide, C6H4Me-N :CBz-OH, prepared by heat-ing orthotolyl isoc-yanide with benzoic chloride on the water-bath,and decomposing t h e product with water, crystallises from ether incolourless needles, melts at 108", and is readily soluble in hot etherand alcohol, but almost insoluble in boiiing water.It; dissolves inwarm soda, being reprecipitated on acidifying the solution, but, whenboiled with excess of potash, i t is decomposed with formation of ortho-toluidine ; i t is very stable towards concentrated hydrochloric acidand sulphuric acid. When its warm solution is treated with phenyl-hydrazine and then cooled, the colourless hydrate of the hydrazoue isprecipitated ; this compound has doiibtless the constitutionC6H4Me:C(OH) *CPh(OH)*NzEzPh,and when its solutions are heated it is quickly converted into a yellowhijdmeoize; it i s not decomposed by cold soda, b u t when warmed withsodium ethoxide i n alcoholic solution it is converted into the hydr-azone of benzoylformic acid.PamtoZyZ [socyanide, C6H41\/Ie*N:C, is a colourlcss oil, boiling at 99"with slight decomposition under a pressure of 36 mm.; it undergoeschange only slowly on keeping.IsocyanoparatohyZ dichloride, CcH4Me*N:CClZ, is a colourless oil withan irritating odour, and boils at 225-226" (uncorr.) ; when treatedwith paratoluidine, it is converted into triparatolylguanidine hydro-chloride.The above experiments having shown that phenylhydrazine com-bines with certain compounds containing a carbonjl group t o formadditive products, which are converted into hydrazones by the loss of1 mol.

The ethereal layer is dis-tilled, and the residue is mixed with water and again distilled. Thecondensed water is yellow, and contains oily drops ; it is heated untilthese drops dissolve, and then allowed to cool, when nitrohomo-rrrtecho7, C7€17N04, separates in golden-yellow lamellse, which melt a t79-80", b q i n to decompose at about 280", are coloured deep red byalkalis, and dissolve slightly in cold water, but are more soluble inhot; water, alcohol, and ether.Homocatechol ( 5 grams) is dissolved in water (150 c.c.), mixedwit,h a solution of sodium nitrite (18.5 grams), and dilute hydrochloricacid added gradually until there is an abundant evolution of nitrogenoxides. The deep-red mixtnre is extracted with ether, which isseparated and distilled, and the brown, crystalline residue is driedover sulphuric acid; it is then crvstallised from boiling benzeneand finally from dilute alcohol. This compoand is a nitrohomo-catechol, C,H7N04, but is isomeric with the preceding compound.Itforms small, sulphur-yellow needles, only slightly soluble in coldwater, but soIuble in hot water, alcohol, ether, or benzene ; it meltsat about 180" with incipient decomposition. When treated withexcess of alkali, it gives a beautiful, purple coloration. I€, however,potassium hydroxide or ammonia is added to a hot solution until thepurple coloration j u s h begins to be produced, the liquid, when cooled,deposits orarigc.-yellow needles of the monobasic alkali salts, whichare easily purified by recrystallisation from water.The potasaiu.msalt has the composition C7H6KN0, + H20. C. H. B.Condensation of Unsaturated Hydrocarbons with Phenols.By W. KOENIGS and C.

The present paper deals with the behaviour of polyatomicphenols. Quinol, resorcinol, arid catechol unite with 2 mols. of theunsaturated hydrocarbons, and well-crystallised diamyl derivativeswere obtained.Pyrogallol yields a diamyl derivative, but a triamylderivative could not be obtained.Dim1 ylquinol, C6H2( C5H1J2( OH),, is obtained by a d d i q snlphuricacid (50 c.c.), with cooling, to a solution of quinol (25 grams) inIt contains a small quantity of catechol1444 ABSTRACTS OF CHEMICAL PAPERS.acetic acid (250 grams), and then gradually adding isoamylene(50 grams, 2.5 mols.) to the cold mixture. After 24 hours, thecrystalline product is collected, washed with acetic acid, dissolved inether, and the ethereal solution shaken with soda, dried over potash,evaporated to dryness, and the crystalline mass thus obtained is re-crystallised from benzene. It forms colourless, compact, tetraponalpyramids, melts at 185", is easily soluble in alcohol, ether, and chloro-form, less so in cold benzene and acetic acid, very sparingly in lightlpetroleum, almost insoluble in water, and in soda, amnionis, andthe fixed alkalis.The concentrated alcoholic solution turns yellowish-red on the additioii of potassium or sodium hydroxide, bnt, on addingwater, unaltered diam~lquinol is precipitated. When warmed iualkaline alcoholic solution, i t yields diamylcluiiione. Phenylhydr-azine and hydroxjlamine are without action on diamylquinol. Ferricchloride, ordinary and fuming nitric acid, and bromine in carbon bi-sulphide all convert it into the corresponding quinone. When warmedwith concentrated sulphuric acid, it is decomposed. It cannot besublimed without decomposition, is not volatile with steam, and isvery stable towards light and air.L)iacstyldiamylqi~inol, C,H,(C5Hll),(OAc),, is obtained by boilingthe preceding compound with acetic anhydride. It crystallises fromalcohol in beautiful, four-sided tablets, melts at 116", is easily solublei n the ordinary organic solvents, and insoluble in water. Whenboiled with dilute alcoholic sulphuric acid, it yields diamylquinol ;with alcoholic potash, it yields diamylquinone.Biamylquinol phenykarbanzate, (KHPh*COO),C,H,(C,H,,),, is ob-tained by warming diamylquinol with phenyl isocyanate.It is in-soluble in most solvents, dissolves sparingly in acetone and aceticacid, separates as a crystal!ine powder, and melts at 248".Quinol diisoaniyl ether, C6H,( OC6H1,),, is obtained by gradually add-ing a solution of potassiiim hydroxide (3.1 grams) in alcohol (15 c.c.)to a warm mixture of quinol (3 grams) and isoamyl iodide (11 grams).It cryvstiillises in silky, colourless needles, melts a t 65", is volatilewith steam, arid is 1-ei.y easily soluble in organic solvents, with theexception of cold alcohol, in which it is somewhat sparingly soluble.Neither the diisoamyl ether nor the diacetate of quinol yields con-densation products with amylene.Diamylpuinonne, C6H40z(C,Hl,)z, is obtained by boiling a mixture ofdiamylquinol (5 grams), alcohol (50 grams), and dry ferric chloride(15 grams) in a reflux apparatus for one hour.It crystallises fromalcohol in long, bright yellow needles, melts at 140°, sublimes inbeautiful, slender, pale yellow needles, is easily volatile with steam,and is easily soluble in ether, benzene, chloroform, and acetone, some-what sparingly so in c d d alcohol and acetic acid, sparingly in lightpetroleum, and almost insoluble in water.It is not altered by treat-*sent with sulphurous acid, but mhen boiled with zinc-dust and aceticacid, it is reconverted into diamylquinol. 'It is noi attacked byalkalis, calcium chloride, aniline, phenjlh~7drazine~ hydrogen bromide,hydroxylsmine, acetic anhj dride, or phenyl isocyanate.DitamyZresnrcinol, CCHZ(C51311)L(0H)2, is obtained in a similar wayto diamylquinol. It crjstallises from light petroleum in slenderORGAN10 OHEMISTRP. 1443colourless needles., melts a t 89", is extremely soluble in all organicsolvents, and is insoluble in water, soda, and ammonia.It dissolveseasily in potassium, sodium, and bnrium hydroxides, and is precipi-tatcd from the solution unchanged by the addition of acids. It iseasily volatile wit'h steam. When boiled in alcoholic solution withmethyl iodide and potassium hydroxide, it yields a dimethyl etherwhich melts a t 64".DiarnyZcatechoZ is obtlained by allowing a mixture of catechol,acetic acid, sulphuric acid, and nmylene to remain five days. Theoily product is freed from polyarnylenes by distillation in a vacuumat loo", and the residue distilled with steam, dried on porous platesin a vacuum, and crysta!lised from light petroleum. It crystallises inaggregates of colourless needles, melts at 60", is very easily soluble inorganic solvents, and insoluble in alkalis.When the alcoholic solutionis treated with a few drops of concentrated potassium hydroxide solu-tion, it assumes a beautiful, blue colour, which changes to dirty greenon the addition of water, and an oil is precipitated, which turns toa dark-green resin when warmed. With ferric chloride, the alcoholicsolution gives a green coloration, and, with lead acetate, a white,gelatinous precipitate, which quickly turns green when dried. Theauthors were unable to detcrrnine if diamylcatechol contains twohydroxyl groups, owing to lack of material.Diarny@yrogaZZoZ, C6H(C,Hl1),( OH),, is obtained when a mix-ture of pyrognllol, amylene, acetic acid, and sulphuric acid is leftfor 5 to 6 days. It crystallises from light petroleum in long, colourlessneedles which turnred on exposure to air, melts a t go", is not volatilewith steam, is very easily soluble in organic solvents, insoluble inwater, sodium carbonate, and ammonia, and dissolves easily in sodiumand potassium hydroxides, yielding a solution which at once turns violet.With ferric chloride, the alcoholic solution gives first a green andthen an intense violet coloration. The triacetate crystallises fromalcohol in colourless, lustrous needles, and melts a t 145"The authors also describe experiments with tetrahydronaphthyl-phenol and metacresolphenylethane.l'etrah ydronaphthy ZphenoZ, C10Kll*C~H4*OH, is obtained by the con-densation of dihydronaphthalene with phenol. When mixed withpumice and heated to dull redness in a current of carbonic anhydride,it is partially resolved into naphthalene and phenol, and the remainderdistils unchanged.Naphthylphenol cannot be obtained from it bydistillation with zinc-dust or with lead oxide.Tetrahydroti a? ht hy ZarLisoiZ, CloHl ,*C,H,.OMe, is obtained by boilingtetrahydronaphthylphenol with potash, methyl alcohol, and methyliodide for four hours in a reflux apparatus. It crystallises fromalcohol in beautiful, long, silky needles, melts a t 71", and is veryeasily soluble in ether, chloroform, benzene, and carbon bisnlphide,more sparingly i n cold alcohol, and almost insoluble in mater.When treated with excess of bromine, it yields a mixture of di- andtri-brominated derivatives. The authors were unable to obtain naph-thylanisoil from it.Kraemer and Spilker (Abstr., 1891, 206) have stated that thehydrocarbons obtained by the condensation of cinnamene with homo-VOL.LXII. 5 6The diacetyl derivative melts at 89"1446 ABSTRACTS OF CHEMIOAL PAPERS.hgues of benzene, by means of sulphuric acid, are converted intoanthracene derivatives when heated at a dull red heat. The authorshave examined the behaviour of metacresolphenylethane, and findthat, when heated with zinc-dust, i t is decompcsed with formation ofmetacresol. When heated alone, a fluorescent compound was obtained,which dissolves in alkali with a yellow coloration, and is, perhaps,hydroxyanthracene ; but the yield was so small that satisfacboryresults could not be obtained.The bye-products formed in the preparation of metacresolphenyl-ethane were found to contain unaltered cresol, and the liquid dicin-namene, C,J€,,, which boils at 310".The latter is also obtained inlarge quantities by allowing a solution of cinnamene in pure sulph-uric acid (1 vol.) and acetic acid (9 vols.) to remain for a time.By DF: FORCRAND (COW@ rend.,115, 284-286).-The heat of neutralisation of pyrogallol by dilutesoda as merrsured by Berthelot and Werner, namely, +6*40, +6.38,and +1.02 Gal., for the three successive hydroxyls, seems to indicatethat the third hydroxyl occupies the ortho-position relatively to theothers, since the corresponding values for catechol are +6*26 and + 1.40 Cal., whilst those for resorcindl are f8.22 and + 7-36, andfor quinol +8.00 and +6.36.The mean value for pyrogallol (4*6U),moreover, is less than that for phloroglucol (+6.09), just as themean value for catechol (+3.S3) is less than that for its isonierides(+ 7.79). I n drawing conclusions, however, from successive valuesobtained with dilute solutions, it is necessary to be cautious onaccount of the very considerable influence of the heat of dissolution.Catechol, for instance, which is apparently the weakest of the threedihydroxybenzenes, is found to be the strongest when the heat ofdissolution is taken into account (see t,his vol., p. 1184).To clear up the matter, the authors have redetermined the heat ofneutralisation of the successive hydroxyls of pyrogallol, calculatedfor the solid state. The total amount is + 116.09 Cal., giving a meanvalue of +38*70 for each hydroxyl.The successive values are ap-proximately +41.34, +3949, and +35.66 Gal. On comparing themean value with those for resorcinol, + 38.60, catechol, + 39-02, andquinnl, + 37.36, it would seem that the constitution 1 : 3 : 5, analogousto tllat of resorcinol, is the more probable, were i t not that the pro-perly calculated successive values ( +38.iO and + 38.50 for resorcinol),which have a far greater indicative power than the mean values,show the essential constitutional difference between the two sub-staiices, namely, the ability of pyrogaliol and the inability. of resorcinolto form intermediate molecular combinations in the course ofneutriillsation. The asymmetrical constitution, necessitating thepara-position for the extreme hydroxyls, is seen to be impossiblewhen the mean value for those groups (+38.50) is compared withthose for quinol, and for the single hydroxyl of phenol (+3S*lO),and this value, moreover, is so near that for resorcinol as t o pointwith certainty to the meta-position for the extreme groups.Thethird group, notwithstanding its ortho-position relatively to theothers, bears practically the same value as the single hydroxyl ofE.

Fischer and Hepp (Abstr.,lk90,911) that trianilidonaphthalene is readily converted into rosindu-lime on oxidation, the object ot the present work was to ascertaiiim hether, on oxidising amidoparadianilidobenzene [NH, : (NHPh), =1 : 2: 51,an indhline of'the benzene series is formed. The author did noteren succeed, however, in preparing tthe amido-derivative. Calm'sparadianilidobenzene (dbstr., 1884, 591) melts at 146" (compare0 Fischer and Wacker, Abstr., 1888, 1286). The diacetyl derivative(Calm, 2oc.c k ) , when heated on the water-bath with nitric acidof sp. gr. 1.4, gives a nitro-compound, NO,*CaH,(NPhAc),, whichcrystallises from alcohol in pale yellow needles, and melts a t 160".The nitro-compound, when boiled with alcoholic potash, gives aT iolet compound which may be an azo-derivative ; on reduction withtin and hydrochloric acid, it yields a substance having phenolicproperties, and this, if heated at 130" with 2U per cent. hydrochloricacid, gives aniline and a carbonaceous residue smelling distinctlyof quinone, so that it is perhaps a quinoneoxime. Rrandrowsky'sdip heny lparazop h en yl ene (quinon edianil) is ob t aiized by heatingeither paradianilidobenzene or its diacetyl derivative with alcoholicpotash.The above-mentioned nitrodiacetylparadianilidohenzene,when boiled with alcoholic sulphuric acid, jields a compound whichORQANIO OHEMISTRY. 1451when heated with alcoholic ammonium sulphide, gives an anhydro-1base, Nih?h-C6H,<Npk>CMe, - melting a t 162-164" ; if, however,2the nitro-compound is first reduced, a basic substance, Cz2H,,N30,melting a t 180" is produced, which gives the last-mentioned anliydro-base on hydrolysis with alcoholic sulphuric acid.D~ormyl~aradianili~obenzene, C20H16NzOz, prepared by boiling para-dianilidobenzetie with formic acid of sp. gr. 1.2 (10 parts), crystallisesfrom alcohol in white needles, and melts a t 168"; when nitratedunder the same conditions as the diacetyl derivative (see above), adinitro-derivative melting a t 215" is obtained. Calm's dibenzoyl-paradianilidobenzene (loc.cit.) yields a trinitro-derivative melting a t248". A. R. L.Condensation Products of the Amidophenols. By E. HAEGELE( H e r . , 25, 2753-2756).-'J!he author finds that the nmidophenols,and especiallly paramidophenol, readily form condensation productswith aldehydes and, with rather more difficulty, with ketones. Thepreparation is similar to that €or hydrazones, a dilute acetic solutionof the amidophenol being shaken with the aldehyde. Heat isdeveloped, and the condensation pi-oduct crystallises out. With orthramirlophenol, the reaction requires the aid of heat.BenzylJdeneparamidophenol, CHPh:N*C6H,*OH, from benzaldehydeand paramido phenol, crystallises i n large scales easily soluble inalcohol, but insoluble in water, and melts at 163".Hydroxybenzylidene-p arumid op henol, 0 H.C6H4* C H :X.C 6HI.0 H, from salicylaldeh yde, formsyellow or orange scales soluble in boiling water and alcohol, andmelts a t 135".

I t separates from etherin yellowish crystals, melts a t 58', and boils a t 163-164" (uncorr.)under a prcssure of 19 mm. ; it rapidIy turns yellow and then red onexposure to the air, and when heated with aniline hydrochloride, ityields an intensely reddish-violet compound,The compound of the composilion GI2HI1NO, prepared from ortho-toluidine in like manner, forms almost colourless crystals, melts at54-55", and boils at 171-172" under a pressure of 19 mm. ; it turnsred on exposure to the air, is decomposed by boiling acids, and com-bines with anilhe and with toluidine yielding red dyes.The con-densation product of furfuraldehyde and paratoluidine melts at43-44', and resembles the compound just described.Furfuraldehyde and benzylamine react readily, yielding an oil ofth'e constitution C40H3*CH:N*CH2Yh ; this substance boils a t 155"under a pressure of 11 mm., and is decomposed by boiling water.The condensation product of furfuraldehyde and piperidine boils at?157-158.5' nnder a pressure of 14 mm., and has the compositionCl5HP4N2O ; its hydrochloride, C,5H24N20,2HCi, is very hygroscopic,and is quickly decomposed by water.Condensation Products of Furfuraldehyde with AromaticBases, By G. J. L. DE CHALMOT (Amer. Chem.J., 14, 310-314)Furfuraldehyde, aniline, and aniline hydrochloride yield a violet-redcrystalline compound, 2C6HiN,C5H4O2,HC1, without elimination ofwater. Schiff represented the composition of this furfuraniline bythe formula C@H3*CH( C6H4*NH,,H~1).CsH4*NH2,H20, but was un-able to prepare free €urfnrandiphenylmethane.The author obtained only negative results on attempting to obtainthe base, although with solutions free from water.With the corresponding toluidine compound, it was found that ondrying for 9 hours a t l.Q0-105', water was lost ; the dried substancewas no longer crystalline, but behaved towards solvents jnst like thecrystalline compound.Among the products of decomposition obtained on heating to 200"were coloiirless crystals of an aromatic base.The author concludes that the water present in the compound isnot united to one of the amido-groups, but is simply water of crystal-lisation.

T.Stereoisomerism of Carbodiphenylimide and Carbodipara-tolylimide. By C. SCHALL and S. PASCHKOWETZKT (Ber,, 25, 2880-2895).--The authors have succeeded in resolving carbodiphenyl-imide and carbodiparatolylimide respectively intfo two modifica-tions (compare Weith, this Jaurnal, 1874, 480 ; Will, Abstr., 1881,905 ; Will and Bielschowsky, ibid., 1882, 1091) by distillation underdiminished pressure. The results vary according to t'he pressureunder which the distillation is condncted, also according to the lengthof time the compounds have been kept after their preparation.SeeORGANIC OHEMISTRY. 1453ing that the two modifications have the same molecular weights,the authors suggest that they are stereoisomerides, and propose torepresent them by the following general configurations c and c. Rz ?YR#R $RThe following may be cited from the experimental portion:-Carbodiphenylimide (freshly prepared) boils at 218" (30.8 mm.) ; thedistillate solidifies and has a melting point of 136". When the latteris carefully crystallised from anhydrous benzene, it melts a t158-160" ; whilst an oily modi6cation which could not be completelyfreed from the solvent was obtained from the benzene solution, Theoily modification is eonverted into the solid one on triturating it withalcohol, and when the latter is heated a t l l O " , the oily modification isformed.The oily modi6cation is converted into carbaidi.de byboiling i t with alcoholic hydrochloric acid, but this reaction takesplace much less readily with the solid modification.Carbodiparatolylimide (freshly prepared) boils ak 238" (35 mm.) ;the distillate subsequently solidities, and has a melting point of about60". When the latter is allowed to remain for 20 hours with drylight petroleum, filtered from the undissolved portion, and the solu-tion evaporated, a modification melting at 49-50' is obtained ; whilstwhen the snbstance melting at 60" is crystallised from anhydrousether, and subsequently extracted with boiling light petrolenrn, amodification melting at 148-149" is isolated.When either of thesemodifications is distilled under diminished pressure, it is partiallyconverted iiito the other. Diparatolylcarbamide is formed when themodification of lower meltin5 point is boiled with alcoholic hydro-chloric acid, or when that of higher meIting point is boiled with aceticacid. A. R. L.Constitution of Nitrosoazo-compounds. By C. WILLGERODT(Ber., 25,2561-2664).-Phenylazimidobenzene, dinitrosoazohenzene,and the two nitrodinitrosoazobenzenes, when boiled with a mixture ofequal parts of fuming nitric and sulphuric acids for one hour, yield thesame compound, namely tetranitrophenylazimidobenzene,NThis result points either to the conclusion that, : (1.) True nitrosoazo-eompounds do not exist, but are azimido-compounds or derivatives ofthe same ; or that (2) nitrosoazo-compounds do exist, but on nitrationare converted into nzimido-compounds.If the latter conclusion isaccepted, then on nitrating dinitrosoazo-compounds, the nitroso-groupin the ortho-position relatively t o the azo-group is reduced and thusbecomes capable of converting the azo- into the azirnido-group, andfurther the nitroso-group in the pnra-posit,ion to the azo-group isoxidised to the nitro-group. On trent,inq mononitromononitroso- anddinitromononitroso-azobcnzene with nitric and sulphuric acids, theauthor obtained tetrnni trophe n yl azoximidobenzene, and not te trani tro-phenylazimidobenzene.Against the assumption that nitroso-groupsC6H3(N02)3'N<&> C6H2( NO,),1452 ABSTRACTS OF CHEMICAL PAPERS.of nitrosoazo-componnds are oxidised and reduced by boiling withnitro-sulphuric acid, is the fact that the nitroso-group of mononitroso-azo-compounds is not oxidised to a nitro-group by dilute nitric acid,by acetic and chromic acids, by fuming nitric acid, or by nitro-sulphuric acid, and that the nitroso-group of niononitrosoazo-corn-pounds is not reduced by nitro-sulphuric acid. The author concludesthat true nitrosoazo-compounds do not exist, but that they are deriva-tives of azimido-compounds.The author reserves the study of the two isomeric dinitrophenyl-azimidobenzenes, nitrosoazoxybenzene and symmetrical trinitroso-pheni lpara bromazobenzene.Tetranitrophenyktzimidobenzene is prepared by boiling phenyl-azimidobenzene, dinitrosoazobenzene, or the two nitrodinitrosoazo-benzenes with 20 times the quantity of nitro-sulphuric acid.Themixture is poured into water and the precipitate extracted withalcohoi and crystallised from toluene or acetic acid. From aceticacid, it separates in bright-yellow plates or prisms, and melts at195-196'. It crystallises from toluene in long, thick prisms con-taining 2 mols. of toluene, and from benzene in yellowish-whiteneedles containing 2 niols. of benzene. It is sparingly soluble in ether,alcohol, and chloroform.TetranitrophenyZuzoximidobenze~, CsH,(NOZ),.N,O:CsH,(NO,),, isprepared in a similar way froni nitronitroso- and dinitronitroso-azo-benzene. From acetone i t is obtained in thin, well formed crystals, fromacetic acid in small, measurable crystals, and large, yellow prisms, andfrom benzene in crystals containing 2 rnols.of the hydrocarbon. Itdecomposes a t 192", is insoluble in ether, sparingly soluble in alcoholand chloroform, and very easily so i n acetone. All the solutions aredeep- y ellow. E. C. R.Metallic Derivatives of Phenylhydraxine. By G. MARTINA(L' Orosi, 15, 37-41) .-The metallic derivatives of pheuylhydrazinedescribed below were obtained by mixing solutions of a metallic salt(1 mol.) and phenylhydrazine (2 mols.). With zinc chloride, thesalt Zn(NHPh:NH,Cl), is formed. It crystallises in small, whiteneedles which rapidly become brown or flesh-coloured.On addinghydrochloric acid to the mother liquor, no double salt is obtained,but oiily phenylhydrazine hydrochloride.With mercuric chloride, it white, flocculent precipitate is formedfrom which metallic mercury is soon deposited even in the cold.Auric and platinic chlorides are likewise rapidly reduced by phenyl-hydrazine ; baric and stannic chlorides are not acted on ; staunouschloride is converted into the hydroxide, Sn(OH),. With cadmiumsulphate, a yellowish or orange-coloured salt of the compositionCd(NHPh:NH,),:SO, is obtained.With ferrous sulphate, small, white needles or hard nodules of thecomposition Fe(NHYh:MH2),:S0, are formed. They rapidly turnbrown on exposure to the air,Copper sulphate yields an unstable ealt which almost immediatelyturns black ; on warming, the copper is reduced to the metallic state.If the precipitated copper salt is thrown on a filter as soon as it iORGANIC CHEMISTRY.1455formed, it swells up and rapidly decomposes with development ofheat.Zn(NHP1i:N H,) ,:S Oa,With zinc sulphate, slender needles of the saltare obtained, soluble in water and in alcohol. On adding sulphuricacid to the mother liquor, the acid salt, H2SO4,Zn(NHPh:NH2),:~0*, isgradually deposited in hard, silvery plates which soon become rose-coloured. With nickel aud strontium sulphates, no precipitates areformed. On adding an alcoholic solution of phenylhydrazine to anaqueous solution of lead nitrate, the basic salt, Pb(OK)NO,, is pre-cipitated.Xylidine forms with zinc chloride the salt Zn ( C6H3Me2-NH2Cl)2,which crystallises in tufts of white or pinkish needles, soluble in waterand alcohol.On adding hydrochloric acidto the mother liquor, the hydrochloride of the base is formed.With zinc and cadmium sulphates, double salts are obtained, and 011adding sulphuric acid to the mother liquors the acid salts are pre-cipitated. No salts are formed with silver and copper nitrates,whilst with lead nitrate it behaves like phenylhydrazine.It turns brown at lU0".S. B. A. A.Action of Orthonitrobenzyl Chloride on Phenylhydrazine.By C. PAAL aud A. BODEWIG (Bey., 25, 2896--2904).--Orthonitro-Eenzyl chloride and phenylhydrazine react with explosive violence ;the action proceeds tranquilly, however, in the presence of a diluent.When the chloride (1 mol.) is added to a solution of phenjlhydrazine(2 moln.) in absolute alcohol (4-5 vols.), and the mixture subse-quently heated for 3-4 hours on the water-bath, phenylhydrazinehydrochloride separates, and, on adding the product to hot watercontaining acetic acid and sodium acetate, a red oil is precipitatedwhich consists of orthonitrobenzylphenylhydrazine 50 - 60 percent.), bisorthonitrobenzylphenylhydrazine (20-30 per cent.), andorthonitrophenylmethaneazobeuzene (5 per cent.), together with ared resin.The oil is extracted with ether, arid hydrochloric acidadded to the solution, when the hydrochloride of the first-namedcompound is precipitated ; the other two compounds (see below),being devoid of basic properties, remain dissolved, aiid are separatedby fractional cry stallisation from glacial acetic acid.Orthonitrobenzyl~henylhydraxine, N02.C6H4.CH,.NPh*NH2, crystal-lises from alcohol in yellow needles, melts a t Z0, and is sparinglyaoluble in light petroleurn, readily so in alcohol and ether ; the hydro-chloride melts at 196--198", and is partially dissociated by a largeexcess of water.The,formyl derivative, N02*C6H4*CH2.NPh*NH*CH0,obtained by boiling the base f o r two hours with concentrated formicacid, crptrtllises from dilute alcohol in lustrous, bright-yellow, flatneedles, melts a t 141-142", and is almost insoluble in light petroleum.Ortharnidobenzylphenylhydrazirie, prepared by reducing the nitro-basewith zinc dust and acetic acid, crystallises from dilute alcohol in flat,white needles or elongated leaflets, melts a t lodo, boils a t 254", and isreadily soluble in the usual solvents except light petroleum ; solutionsof its salts are not dissociated by water.The forrnyZ derivative is ob-tained by treating formylorthonitrobenzylphenylhydrazine dissolve1456 ABSTRAUTS OF UHEMIUAL PAPERS.in alcohol with zinc dust and hydrochloric acid at as low a tern-perature as possible ; i t crystallises from alcohol in Bmall, white,stellate groups of tables, melts at 157', and is almost insoluble in waterand light petroleum ; the formyl group is eliminated on heating withacids and alkalis, and when the compound is heated above its meltingpoint, it yields an anhydro-base, C,H,<N 2 - cE3:Bis or thonitro benz y lp hen y 1 h y d razin e , N, E l Ph ( C H,.CGH1*N 0,) ,, cry s t a1 -lises from alcohol in red needles, melts at 128", and is sparinglysoluble in ether and alcohol, readily so in benzene. I t remains un-altered when boiled with acetic anhydride or when its solutions areheated with mercuric oxide, and yields, on reduction, amorphoussubstances which were not further examined.Orthon itrophenytmetkaneazo benzene, NO,* C6H4*C H,*N,Ph, is isolatedfrom the final mother liquor obtained iu crystallising the last-describedcompound ; it cryst.allises from alcohol in dark red needles, melts at154", and on reduction with zinc dust and acetic acid, gives a base,CI3Hl3K3, which crystallises in flat, white needles, and melts at,218-220" ; it is now being further investigated.cc-Phenylhydrazidopropionie Acid.By A. REIS-SERT (Rer., 2 5 ,2'701--2i05).-The compound described by the author (Abstr., 1884,1152) as asymmetrical a-phenylhydrazidopropionic acid is, in accord-ance with v. Miller and Plochl's statement (this vol., p. 1196), thesymmetrical derivative obtained by Fischer and Jourdan (Abstr.,1884, 53), and subsequently by Japp and Klingemann (Trans., 1888,535). The melting point previously given by the author (Zoc. cit.) istoo high.Ethyl phenylhydrazidopropionate, also described by the author(Zoc. c i t . ) , is an oil which, if left for a time in the desiccator, under-goes oxidation to ethyl phenylhydrazinepyruvate. On boiling i t withconcentrated hydrochloric acid for four hours, a-milido propionic acid,phenylhydrazinepyruvic acid, and ammonia are produced.a-~~itrosoanilido~~ro~ionic acid, NO*NPh*CHMe-COOH, is preparedby dissolving a-anilidopropionic acid (1@5 grams) in concentratedhydrochloric acid (14 grams), and, after diluting with water, addingt o the cooled mixture st concentrated solution of potassium ui trite(8.5 grams).When purified by repeated dissolution in ammonia andreprrcipitation with acid, it melts at 88.3" (cow.): and is very readilysoluble in most solvents except light petroleum. The author hopes,by the reduction of this nitroso-derivative, to obtain the unknownasymmetrical a-phenylhgdrazidopropionic acid.Alkyl Derivatives of Hydroxylamine. By R.BEHREKD and E.KONIG (Annulen, 271, 92--94).-The authors describe further quan-titative experiments, which afford additional proofs lhat the oxidationproducts of benzylnit robenzylhydroxylamine and of nitrobenxylbenzyl-hydroxylamine are identical, and are formed in the same quantities inboth cases (compare Abstr., 1891, 1032).By J. L. BRIDGE (Amer. Cham. J., 14,276-286) .-Quinoneoxime methoxide, C6H40:NOMe, was preparedCH *NPh>NR,A. R. L.A. R. L.E. S. K.Quinoneoxime EthersORGANIC CHEMISTRY. 1457by treating silver nitrosophenol suspended in ether with l a times thecalculated amount of methyl iodide. The dark brown, tarry massobtained by spontaneous evaporation of the ethereal filtrate wasextracted with hot light petroleum, and the solution decolorised withcharcoal, when i t yielded, on concentration, flat, yellow needles melt-ing at 83" after recrystallisation. It dissolves readily in organicsolvents and in hot water, and i n considerable amount in cold wateror light pet'roleum, has a strong, pleasant, ethereal odour, and isreadily volatile with steam ; if not qiiite pure, it quickly decomposes,like quinone, turnipg first green and then dark brown.The same substance is formed by gently warming R solution ofsodium nitrosophenol in methyl alcohol with methyl iodide.About0.2 gram of dark red needles, probably a polymeric nitrosophenol, arcobtained for each gram of nitrosophenol taken. This substance isinsoluble in organic solvents, but dissolves in alkalis and ammoniawith a deep red coloration, and is precipitated unchanged by acids orcarbonic anhydride.It begins to decompose at 250" without melting.The analyses made did not yield concordmt results, as i t burns withvery great difficulty. Nitric acid (sp. gr. 1.4) converts it quantitativelyinto 1 : 2 : 4-dinitrophenol melting at, 114". Tin and hydrochloricacid reduce i t to paramidophenol melting at 180".The methoxide is quantitatively converted into a, dibromide,C6HAO:NOMe,Ur2, by addition of bromine (1 mol.) to the chloroformsolutjion. The reaction is complete in half an hour, and no hpdrogenbromide is noticed. It i s colourless, and wystallises from chloro-form in four-sided plates, softens at 113", and melts at 118" withoutdecomposition.Quinoneoxime ethoxide, C,H,O:NOEt, is obtained in a similar mannerto the methoxide ; i t cystallises in jellow, rhomhic or hexagonal plates,melts a t 30°, and has a strong ethereal odour.I t is easily volatile withsteam, and dissolves readily in all solvents, being l e ~ s t soluble in coldwater and light petroleum. The methoxide and ethoxide do n o tresemble nitrosophenol, but show a very close resem5lance t o benzo-quinone. The conclusive proof that they are compounds of quinone-oxime, and not of nitrosophenol, is that a-benz.~lhydro3ylamineconverts quinone quantitatively into the compound C,H,O:NO.CH,Ph,which is identical i n every respect with the compound obtained fromsodium or silver nitrosopheriol and benzyl chloride.Qziinoneoxime acetate, C6H40:N OAc, is obtained by treating silvernitrosophenol suspenied in much absolute ether with freshly-distilledacetic chloride.The compound formed crjstallises in light yellowneedles, and melts at 107". It is but slightly soluble in water, andodourless ; its Eolutions in ether and i n alcohol are green, like those ofnitrosophenol.E thy1 quinoneoximecarboxyla te, C,H,O:N*O-COOEt, is obtainedwhen silver nitrosophenol and ethyl chloroforniate, in molecular pro-portion, are suspended in absolute ether, and gently heated for ashort time ; i t crptallises in yellow plates melting at 110".Quinorieoxime benzoate, C6H40:NOBz, is obtained by treating drysodium or silver nitrosophenol with benzoic chloride, or, better, byshaking an alkaline solution of nitrosophenol with benzoic chloride.I f dry and finely powdered it causes sneezing1458 ABSTRACTS OF CHEMICAL PAPERS,It forms pale yellow needles melting a t 172-174".The solut'ion inalcohol is green, but its colour is not so marked as that given bynitrosophenol or the acetate.&u,inoneoxime benxoxide, C6H,0:NOGH2Ph, is formed when silvernitrosophenol, suspended in absolute ether, is heated for severalhours wit'h benzyl chloride (2 niol.) until the smell of the latterhas disappeared ; it crystallises in yellow, rectrangular or rhombicplates and melts a t 63.5". The same substance is formed by heatingsodium nitrosophenol dissolved in alcohol with benzyl chloride. It isinsolnble in water, but readily soluble i n all organic solvents exceptIiglit petroleum.It has no odour. When treated with tin andhydrochloric acid, it is converted into paramidophenol, whilst muchbenzyl chloride is also formed. It is also obtained quantitatively bytreating quinone (1 gram) dissolved in water (2.50 c.c.) with thecalculated amount of a-benzylhydroxylamine hydrochloride dissolvedin water containing a few drops of hydrochloric acid.The resnlts obtained show that the properties and stability ofquinone and its derivatives depend entirely on the negative or positivecondition of the molecule. w. T.Action of Amido-Bases on Sodium Glyoxalsulphonate. By0. HINSBERG (BET., 25, 2545--2547).-The author has already shown(Abstr., 1888, 372) that whereas aniline acts on sodium glyoxalsulph-onate with formation of anilidoacetanilide, the napbthylamines yieldsulphonic acids of naphthindoles. Benzylamine behaves in a similarmanner to aniline, yielding the benxiylamide of benzylamidoacetic acid,C H,Ph*NH.CO.CH,.NH.CH,Ph, which forms an oil, but yields withhydrochloric acid a salt, crystallising in colourless plates. Ethyl-F-naphthylamine, on the other hand, yields s o d i u m ethyl-P-naphth-iadolesulphonate, CI4H1,NSO3Na, which crystallises in slightly yellow-ish needles, and is decomposed by hydrochloric acid with forma-tion of a substance free from --- snlphur, the latter being probably ethyl-N Ht /3-mphthoxindole, C,oH,< CH,> CO.H. G. C.Action of Acetic Chloride on Orthohydroxyaldehydes. ByW. P. BRADLEY and F. B. DAINS ( A m e r . Chern.J., 14, 293-300).-Psrachlorosalicylaldehyde was dissolved in a slight excess of glacialacetic acid, and to it was added half its weight of acetic chloride.The reaction was immediate, with evolution of much heat ; it was com-pleted by heating on the water-bath after i t had been left for some time.By pouring into water, dichlorodisalicplaldehyde, together with someunchanged chlorosalicylaldehyde, was precipitated ; the latter sub-stance was removed by treatment with dilute alkali. The yieldareraqes 60-7'0 per cent,. of the theoretical. From a hot concen-trn ted solution in alcohol, fine, white, silky needles of dichlorodi-salicylaldehyde were obtained ; from more dilute solutions, it comesdown in slender, mossy filaments. It iseasily soluble in alcohol, ether, acetic acid, benzene, chloroform, andcarbon bisulphide, less soluble in light petroleum.It easily dissolvesIts melting point is 172"ORGANIC CHEMISTRY. 1459in conceatrnted sulphuric acid, giving m amber-coloured solution,which. when poured into water, deposits quantitatively parachlor-snlicylaldeh yd e.Dibromo- and dichloro-salicylaldehyde gave no condensation pro-ducts with ncet8ic chloride, even in a sealed tube a t 115-130".Paranitrosalicylaldehyde, when treated in the same way as thechloro-compound, does not give a condensation product, but whenheated a t 100" in a sealed tube, a small quantity of dinitrosalicyl-aldehyde is obtained. It dissolves with difficulty in alcohol, aceticacid, ether, chloroform, carbon bisulpbiile, and light petroleum, andbiit little more freely in benzene.The sulphuric acid solution, whenpoured into water, gives pnranit,rosalic;ylaldeh yde.Orthoilitrosalicylaldehyde appears to be unaffected by acetic chlorideunder any conditions.a-Aldehpdo-p-naphthol condenses very readily under the action ofacetic chloride, with development of heat. The yield is nearly quan-titative. The product, p-diorthoh7/droxy-a-na~~~~aldehyde, dissolveswith difficulty in the ordinary solvents. From benzene or acetic acid,itt is deposited in small, hard, nearly white crystals, melting at 241".The solution in sulphuric acid is dark red, with a green fluorescence ;on diluting it with water, a-aldehydo-/3-naJphtlhol is deposited.Paramethylsalicylaldehyde gives a nearly quantitative yield ofpnradimeth;yldisalicylaldebyde.The pure compound melts at 141" ;its molecular weight, determined by Raoult's method, using aceticacid as solvent, was 2.51-2 ; the calculated value is 254. It is easilysnluble in most solvents, but dissolves sparingly in light petroleum.It crystallises from petroleum in bea<utiful, oblong tables, pointed atthe ends. Attempts to oxidise themethyl groups to carboxyl have failed; protracted boiling with a15 per cent. alkaline solution of permanganate produced noeffect.It is easily volatile with steam.Acetic chloride has no action on orthoaldehydosalicylic acid.It appears probable that acetic chloride can secure the quantitativecondensation of all orthoh;rdroxya,ldehydes in which only hydrocarbongroups are joined directly to the benzene ring.The introduction ofnegatlive groups hinders or entirely prevents condensation. Thepresence in the molecule of a chlorine or bromine atom reduces theyield 30-40 per cent.

The pure acid is obtained bydrying the crude product on porous plates and precipitating itf [*om the chloroform solution by petroleum. It crystallises in beautifulleaflets, has a very faint odour, melts a t 120-121", is easily solublein alcohol, ether, chloroform, benzene, and acetic acid, but insolublein light petroleum and cold water. When pure, it yields a colourlesssolution with soda, but a trace of impurity causes the solution toturn purplish-red. The author was unable to obtain a stereoisomericacid from the crude product similar to the acid obtained by Roser andHaseloff by the action of bromine on phenylpropiolic acid.By ex-tracting with ether the porcelain plates used in the purification, anoil is obtained which is completely soluble in soda, but is not adichlorocinnamic acid.

S.HORGANIC CHEMISTRY, 148 1plant. It was only introduced into Europe in 1888, and has nothitherto been chemically investigated. The material examined wasobtained from Schimmel, of Leipsic. It is clear, dark-yellow in colour,has a strong aromatic odour, and a sp. gr. of 0.901 at l8", 0.896 at20". It is very feebly laevorotatory, the small amount of the rotationbeing due to the presence of nearly equal quantities of dextro- andlaevo-rotatory constituents. It forms a clear solution in alcohol, ether,benzene, light petroleum, acetic acid, and fatty oils. In chloroformand carbon bisulphide, it forms a cloudy solution, but the solution inchloroform is rendered clear by the addition of a small quantity ofalcohol.It contains neither nitrogen nor sulphur, and is neutral tolitmus. It is attacked by metallic potassium in+the cold, gives a dark,somewhat violet coloration with ferric chloride, and decolorises potas-sium permanganate in the cold. Its constituents were partially sepa-rated by repeated fractional distillation, and isolated and identifiedby chemical means. The oil was thus found to contain : (1) dsxtro-rotatory limonene, ClOH16 ; (2) dipentene, ClOHl6 ; ( 3 ) terpineole,C,oH180 ; and (4) carvol, Cl0H,,O, all of which are nearly related toone another, and for the most part interconvertible.C.

Ofthese, digitonin is useless as a remedy for heart disease, and, more-over, causes severe local inflammation, whilst digitoxin is unsuitableas a drug on account of its complete insolubility in water. The othertwo would be suitable if prepared pure. The digitale'in of Schmiede-berg is a mixture; not so, however, his digitalin, which is achemical compound, and is now prepared pure, acccrding to theauthor's directionfi, by Boehringer, of Waldhof, and sold under thename of " Digitalin zierum." This drug is perfectly uniform in itsoperation, gradually producing cessation of the heart's action, but noinjurious secondary effects.Other preparations, such as " Digitalinurncy.ystallisatum " and '' D. pula. pulv.," are impure, and consequentlyirregular and often injurious in their action. The first of these,indeed, is nearly pure digitonin." Digitalirz verum '' is an amorphous, white powder, which is inso-luble in chloroform and in ether, swells u p in water, and dissolves init to the extent of 1 part in 1000. 50 per cent, alcohol dissolves1 part in 100, absolute alcohol still more. The pure substance hasbut a feebly bitter taste. A s tests for its purity, the following maybe used:-(1) a few particles placed in a test-tube with 2 C.C.of 10per cent. aqueous potash should remair white for at least one minute ;presence of the other amorphous glucosides causes an immediateyellow coloration. (2) It is stirred with water t o a thin paste, 22parts of amyl alcohol added, with .shaking, for every 100 of waterused, and the whole allowed t o remain in a corked flask ; if digitoninis present, it separates out within 24 hours in small, crystallineagglomerates. When heated with strong hydrochloric acid, best withths addition of 50 per cent. alcohol, digitalin is converted intodigitaligenin, C16H2202, dextrose: and digitalose, CTHI4O5, a sugar whichcould not be obtained crystalline, but which, when oxidised withbromine, yields digitalonic Zactone, C,H,,O,.This substance crystal-lises in fine, colourless prisms, easily soluble in water and alcohol,sparingly in ether.

By R.WOLFFENSTE~N (Ber., 25, 2777--2785).-When pyridine is treatedwith double the quantity of hydrogen peroxide in 3 per cent. solu-tion, it quickly becomes neutral and then acid, and leaves, 011 evapor-ation, a syrup smelling of fatty acids. If the residue is extractedwith chloroform, and the extract evaporated and boiled with baryta-water, piperidine and ammonia are evolved, leaving a residue ofbarium glutarate. The formation of hhe latter by the oxidationof piperidine may be readily understood ; the imido-group is elimin-ated, and the two methylene groups previously combined with it.are oxidised to carboxyl.The portion insoluble in chloroformalso consists chiefly of glutaric acid. If the chloroform extract isdistilled, it undergoes decomposition, the chief portion passing over at270") and becoming solid on cooling ; it crystallises from alcohol inlustrous tablets, and consists of gZutarimide, CH2< cH2'co>NH, CH2.C0 themanner of formation of which is also manifest ; it is a true derivativeof piperidine, and has poisonous properties. There is also obtainedin the distillation a small quantity oE oil which shows the pyrrolinereaction, and may be a methylpyrrolidine.If piperidine is treated with a quantity of hydrogen peroxide suffi-cient only to add 1 atom of oxygen to the molecule, the product, after.24 hours, no longer smells of piperidine, but has a slightly basicreaction and strongly reducing properties.It is purified by distilla-tion in a cnrrent of superheated steam, conversion into the platino-chloride and then by the action of hydrogen sulphide into thehydrochloride, which has the composition C5H,,NOC1, and gives all thecharacteristic reactions of an aldehyde. It must therefore be thehydrochloride of 8-amidoz;aZel.aZdehyde, NH.L.CH2*CH2*CH2.CH,.CH0,the piperidine ring having been split between the imido- and one ofthe methylene groups, and the latter oxidised t o the aldehyde group.The free amidovaleraldehyde is obtained by the action of potassiumcarbonate on the salts, and on evaporating the ethereal solution crys-tallises in white plates ; it melts at 39", and is exceedingly soluble inwater and light petroleum ; the hydrochlol-ide crystallises from acetonein monosymmetric crystals, the hychobrornide melts at.lSO", and thehydyiodide is a syrup. When the base is heated alone or with solidpotash, it loses the elements of water, forming tetralzydyopyridine. Thelatter is a strongbase which absorbs carbonic anhydride from the air,has an odour intermediate between that of pyridine and piperidine,and, on distillation, undergoes gradual decomposition ; its aumchbride,C,H9N,HAuC1,, is microcrystalline, melts at 141°, and is fairlyJK. WORGANIC OHEXISTRY.1485soluble in water and alcohol ; the platinochloyide forms small, thickprisms, and the hydrochloride and hydrobi-omide melt at 230" and 178"respectively, both previously undergoing decomposition.Nicot'ine, as already shown by Pinner and the author (this vol., p.l O l O ) , when treated with hydrogen peroxide, also yields an acidcontaining an additional atom of oxygen ; it has strongly reducingproperties, aid, on heating, loses water, forming dehydronicotine. Theabove reactions therefore form additional evidence in favour of thepresence of the piperidine r i n g in nicotine.If piperidine is mixed with an equal weight of hydrogen peroxide,and allowed to remain for some time, crystals separate, having thecomposition C5H,N0, and melting a t 129"; the molecular weight agreeswith the above formula, and the substance does not form a nitroso-derivative.but Pives the violet Dheiiol reaction with ferric chloride, 0 (:H2*C(0H)CH2-- CHzyN* and must therefore be an a-l2ydi"os~~ipei*idi?ze, CH,<CHZ-CO It is isomeric with Schotten's piperidone, CH,<cH2,CH2>NH, andmay also be obtained by oxidising amidovaleraldehyde with cupricacetate.Ozone acts on piperidine in the same manner as hydrogen peroxide,but is less active. Pyridine is only attacked with difficulty by hydro-gen peroxide, and yields formic acid simply.By A. LADENBURG (Ber., 25, 2768-2772).-Nipecotinic acid, COOH.C5NHl(,, obtained from the hydrochloride(Abstr., 1891, 735), yields hard, white, and highly refractive crystals.It is exceedingly soluble in water, sparingly so in methyl alcohol, andinsoluble in alcohol or ether.It only showsdecided acid characters when in concentrated solutions, and anamorphous deliquescent sodium salt was the only salt which could beobtained. On the other hand, as a base it forms a series of crystallinedouble salts. The platinochloyide yields orange-red prisms melting a t212-213" (corr.) ; the aurochloride golden-yellow needles melting a t197" (corr.) ; the double salt with mercuric chloride,is crystalline, and melts at, 229-231", but begins to decompose a t100" ; the bismuthoiodide forms ruby-red crystals. That this acid is asecondary amine is shown by the formation of a nit7-oso-derivative,COOH*C,NB,*NO, which crystallises i n prisms, and nielts a t111-112".When the sodium salt is heated with methjl iodide(1 mol.) at lUO", and the product obtained is tyeated with silverchloride, methyl nipecotiiiate hydrochloride, COOMe*C5NHlo,HC1, isformed. It is soluble in alcohol and ether, crystallises in needles, andnielts at 215-217". The pkttinochloride crystallises in plates meltinga t 207-208". I f excess of methyl iodide is employed, a dinzethylhydrochloride (nzethyl u-?nethylwipecotinate hydrochloride) is obtainedas a syrupy mass, which yields a crystalline p latinochloride, meltiuyat 233-235".

After purification, the latter forms a liquid boilingat 265" (con..), which from the analysis and vapour density has theformula C12H2,N,, and must therefore be a dimethyldipippridyl. Itunites with the moisture of the air, forminga hydrate crystallising incube-like crystals, the water being again given off in dr-y air. Thehydrochloride, C,H,aW,,2HCl, forms colourless crystals, stable in theair ; the ylntinochloride separates in reddish-yellow plates, even fromvery dilute solutions, and melts at 236", ,previously becoming dark ;the aurochloride, mercurochloride, and pzcyate are also crystallinecompounds.An attempt was made to eliminate the methyl groups, and thusconvert the compound into dipiperidyl ; the elimination proceeds withconsiderable difficulty, the chief product of the reaction beingpiperidine.

PINKUS (Ber., 25, 2798-2806).-Gabriel andhis pupils have shown that trimethylene chlorobromide acts onthioamides with formation of penthiazolines having the generalformula RC<N.CR,>CH2.I n the present paper, the author de-scribes the results obtained by substituting amides for the thio-derivatives.Formanilide and trimethylene chlorobromide react with one anotherat the boiling point of the latter, forming a mixture of two baseshaving the formulae C13H,,N2 and Cl2H1,N respectively, carbonicoxide being also evolved. The former base is identical with themethenyldiphenylamidine described by Wall ach, its formation beingbrought about by the action on the excess of formanilide of thehydrogen chloride set free during the process. The second baSe maybe obtained much more readily and unmixed with the amidine bysubstituting aniline for formanilide.The base contains a tertiary nitrogen atom, and hence both hydro-gen atoms of the amido-group have been replaced, one halogen atomof each molecule of the chlorobromide having been eliminated witheach of these hydrogen atoms ; the remaining halogen atoms wouldmost probably combine with hydrogen atoms in the benzene nucleusforming a compound having one of the following constitutionalformulae :-S-CH,H2/\/\HZ I I iH\ANAE2 - I d\/\/=2 I l lH, H2",\,HZ I IHZThat the base is in reality a derivative of tetrahydroquinoline isproved by the fact that it may also be obtained by the action of tri-methylene chlorobromide on that compound ; in order to ascertainwhich of the above formuh is correct, the action of the chlorobrom-id e on formorthotoluidide and formoparatoliiidide was examined, theresult showing that whilst the para-derivative readily yields ananalogous base, the ortho-derivative behaves in a different manner.Hence the first of the above formulae must be correct, for, as will beseen, no such compound can be formed if the ortho-position is alreadyoccupied, as it is in formorthotoluidide.The base C12H15N is also formed in small quantity by the re1492 ABSTRACTS OF CHEMICAL PAPERS.duct>ion of Reissert's a-keto-y-juloline (this vol., p.883) ; this fullyagrees with the above constitution, and the name of the substance,therefore, becomes, in accordance with Reissert's system, jdolidine.JuloZidine is a colourless, crystalline mass which melts at 40°, boilswith considerable decomposition at 280", and becomes brom-nish-redafter a time ; the hydrocldoride, C12H15N,HCl, crystallises in whiteprisms, is partially dissociated by water, and melts at 218"; tbehydriodide melts at 219-222", the picrate at 165", and theplatino-chloride at 220".The base gives a deep blood-red coloration with a11oxidising agents ; purple-red needles having a metallic lustre, some-times separate out, but gradually become colourless. Towardsmethyl iodide, julolidine behaves as a tertiary base yielding a meth-iodide which forms colourless crystals, melts a t l86", and is notattacked by potash.The base obtained from formoparatoluidide is an oil, but yields acrystalline hydriodide, Cl2NH1&Ie,HI, and shows reactions similar tothose of julolidine. Formorthotoluidide, on the other hand, yields,with trimethylene chlorobromide, a salt, having the formulaC,H4Me*N ( CsH,X),,HX, X being partly chlorine and partly bromine.This substance only loses the remainder of the halogens with greatdifficulty, and then forms tetrahydrorthotoluquinoline, CloHlsN (com-pare Ziegler,Abstr., 1888, 609).The free base melts a t 252", thehydrochloride at 210°, the picyate a t 168", tthe platinochloride a t 212",and the nitifloso-derivative a t 136".Paramethoxyquinoline is also at tacked by trimethylene chloro-bromide with formation of paramethoxy~uZolidine, ClzNH14*OMe, whichis a pungent-smelling liquid ; its hydrochzoride separates from waterin long needles, and from alcohol in compact crystals, melts a t 188"with decomposition, and gives no coloration with ferric chloride ; theplatinochloride melts a t 209-210".The act ion of t rime thylene c hlorobromide on benzenesulphanilideand of ethylene bromide on benzylamiiie was also examined, but inthe first case no reaction takes place, and very little in the second.HI.G.

LORGANIC CHEMISTRY. 1497Nicotine. By A. P~NNER (Ber., 25, 2807-2821).-By the actionof bromine on free nicotine, large quantities of resinous products areformed; whilst the action of bromine on a solution of nicotine inacetic acid or hydrobromic acid gives rise i u the first place to an oilyadditive product from which the bromine is eliminated by treatmentwith sulphurous acid. I n acetic acid solution the reactioii quicklygoes further ; hydrogen bromide is foymed, and thc product containsthe two compounds C,,H,N,Br, and C,,H,N,Br,O,, of which the formeryields the well crystallised perbromide, CloH,N,Br,,HBr3, describedby Huber (AnnaZen, 131, %7), and Cahours and Etard (Compt.r e d . ,90, 1315 ; BUZZ. Xoc. Chim., 31, 457) ; the latter yields a colourlesshydrobromide, C,,H8N2Br,O3,HBr, formerly obtained in an impurecondition by Laiblin.The perbromide, CloH,N2Bia2,HBr3, is obtained by adding bromine(39-4 parts), dissolved in acetic acid (4-5 parts), to a solution ofnicotine in acetic acid (5-4 parts). The oily product first formeddissolves on allowing the mixtzre to remain, o r 011 gently warming ita t 50-60". The perbromide crystallises from the clear solutionafter two days in monosymmetric, chrome-red scales or flat, yellowish-red needles, is easily soluble in warm acetic acid, sparingly so inwater, melts at 163" with decomposition, smells of bromine, which itloses on drying, and is decomposed by boiling with water withevolution of bromine and production of a colourless solution, whichprobably contains the base as hydrobromide.The complete combus-tion of the substance is extremely difficult, and as the numbersobtained on analysis do not agree very well with those demanded bytheory, the above composition was also proved by titrating the pro-duct with sulphurous acid, by estimating the amount of hydrogenbromide formed in the reaction with soda solution, and also by pre-cipitation with silver nitrate. The results obtained in this way agreewith those required by the formula given.The free base, dibromodehydronico tine, Clo138N,Br2, is obtained bytreating the perbromide with ammonia.The hydrobroinide is veryeasily soluble i n water. The picrate, C,,H,N2Br~,C6H2(N0,)3*OH, isobtained by heating the perbromide with water, and adding picricacid to the aqueous solution ; also by adding bromine (6-8 atoms) toa solution of nicotine in hydrobromic acid, boiling until the mixture isfree from bromine, and then adding picric acid, or by reducing the per-bromide with sulphurous acid and adding picric acid. It crystallisesfrom water in large, lustrous, highly reflaactive, yellow prismd, darkensa t 177", melts a t 180°, and then decomposes with much frothing.The pZatinochZoride crystallises in long, yellow needles, darkens a t200", does not melt at 250", and is very sparinglg soluble in water.Dibronzodiox2/dehyd;ronicotine hydrobromide, CloHsN2O2Br2,HBr, is ob-tained by heating nicotine (10 grams) with aqueous hydrobromicacid (20 per cent., 25 grams) and bromine (25 grams)in a sealed tubefor 10-12 hours on the water-bath.It crgstallises from water inslender, white needles, or colourless, lustrous, flat prisms, begins todarken at 200°, decomposes on further heating, and is easily solublein hot water, sparingly-so in the cold.

When the free base is oxidised withalkaline permanganate, it yields nicotinic acid.Dibromodehydronicotine, when treated with strong bases, yieldsmethylamme, oxslic acid, and a compound containing nibrogen ; thelattcr has not yet been isolated.The crystallised perbromide is treatedwith a slight excess o€ sulphurous acid, and to the colourless liquidthus obtained an excess of barium hydroxide is added, the mixturefiltered, and then heated to boiling, and distilled with steam as longas the distillate is alkaline.

By 0. HESSE (AnnaZen, 271, 100-126).-The greater part of this paper consists of a description of well-known salts of hyoscyamine, atropine, and hyoscine, and of a discus-sion OP the results of other chemists' work on the nlkaloi'ds ofbelladonna.Hyoscine has the composition C17H,,N04, and not C1711,,N0,, psfiupposed by Ladenburg and Merck; it melts at about 55", and dis-solves freely in ether, chloroform, and alcohol, but is only moderatelyeasily soluble in water ; its specific rotatory power in alcoholic soh-tion a t 15" is [a]= = -13.7".The author proposes that Ladenburg's pseudotropine or hydroxy-tropine should be called oscine; the composition of oscirie is C8HI3NO2,not CsH,,NO.Benzoylosciize, Cl5HI7N04, prepared by heating oscineat 80-100" with an equal weight of water and a large excess ofbenzoic anhydride, crystallises from chloroform in needles, melts at59", and is readily soluble in ether, alcohol, chloroform, and acids, andmoderately easily in water. The nurochloride, C15H,7N04,HAuC14,crystallises in small, yellow needles, and melts at 184".Atropamine platinochloride (compare Abstr., 1891 , 228) crystal-lises in yellow scales, and melts a t 203-204" with decomposition.Hyoscine (Scopolamine).

Pharm.,230, 291-32O).-When an aqueous solution of berberine sulphate istreated with excess of bromine In the cold, berbzrine tetrabromidehydrobromide, C,oH17N04,Br4,H13r, is formed ; but this, when heatedat, 100" or treated with cold alcohol, loses 2 atoms of bromine andposition product of dibromodehydronicotine.

When heated a t loo", or whenboiled with alcohol, i t is converted into the dibromide, C20H21N04Br2,which in the latter case crystdlises with 3H20. The dibromide, whenheated with alcoholic potash, loses CH,Br, one of the two methoxylgroups being destroyed, and yields a compound C19Hl,N04Br. whichis not a hydrobromide, for it does not give silver bromide with silvernitrate, but a crystalline corn pound CI,H18N0,Br,AgN0,. Bydrober-berine dibromide still has basic, properties, for it forms a platino-chloride, ( C20H2,N04Br)2,HzPtC11;. When reduced with zinc andhydrochloric acid, it yields hydroberberine.Various compounds of hydroberberine with ethyl iodide and brom-ide, and of these with gold and platinum chlorides, were prepared ;these are tabulated below. Hydroberbeiine ethiodide, when treatedwith silver oxide, yielded a n ethylnmrrionium base, CZoH,,NOaEt*OH + 4H20, melting a t 163-165". When this is heated in a current ofdry hydrogen, it loses not 4 but 5 mols. HzO, ethylhydroberberine,C20H,,E tN04, being presumably formed. This substance crystalliseswith 3H,O, when i t melts at 240-245"; when dried at loo", i tloses 2H20, leaving C20HznEtNO~ + HzO, or C20H20N04,EtOH. Italso crystallises from a solution in chloroform and alcohol with4H20, and then loses 3Hz0 when dried a t 100, 1eavir.g the same com-pound as before. This substance is quite distinct from the ethyl baseof hydroberberine from which it mas prepared ; it is not, as was to beexpected, a tertiary base, but is a quaternary compound, and gives noalkaline reaction. With ethyl iodide, for example, it forms not an ethyliodide additive compound, but a hydriodide from which a base cannot; beset free by the action of potash.

The residual syrup, which crystallised oncooling, was dissolved in hot water, the sulphuric acid accuratelyprecipitated with barium hydroxide, and the solution filtered andevaporated to crystallisation. Not lysine, but lysine carbonate, orperhaps more properly, lysine lysinecarbamate, 2C6H14N202 + CO,,wa8 obtained ; this substance loses its caybonic anhydride whenheated at 110" in a current of air freed from that gas.If the dihydrochloride is evaporated to dryness on the water-bathwith excess of milk of lime, and the residue distilled in a current ofhydrogen, various basic products are obtained.

1502 ABSTRACTS OF CHEMICAL PAPERS.P h y s i o l o g i c a l C h e m i s t r y .Air Vitiated by Respiration. By J. HALDANE and J. L. SMITH( J . PnthoZ. and BacterioZ., I, 168--186).--I?rom experiments on humanbeings the following conclusions are drawn :-1. The immediate danger from breathing air highly vitiated byrespiration arises entirely from the excess of carbonic anhydride anddeficiency of oxygen, and not from any special poison. Experimentson animals, consisting of injecting the products of respiration intothem (obtained by condensing the products of respiration expiredinto a Liebig's condenser), caused no more iil-effect than distilledwater.2. Excess of carbonic acid rather than deficiency of oxygen is themore potent cause of hyperpncea and hEadache.A practical conclusion dmwn from these experiments is, that theunpleasantness of close rooms is due rather to the effect producedthrough the sense of smell ; and, therefore, that personal cleanlinessis more important than ventilation; in fact, the odours that arisemay be removed by other means than the excessive ventilation nowconsidered so necessary.W. D. H.Formation of Sugar from Peptones in Blood. By R. L~PINE(Compt. rend., 115, 304-303) .--Purified commercial peptone (-0.2 to0.5 gram) is dissolved in the recent arterial blood (40 grams) of ahealthy dog, defibrinated, or better, treated with sodium fluoride. Inless than an hour the peptone is no longer to be recognised by thecolorimetric reaction vith copper sulphate, and the amount of sugarin the blood is found to have increased.With the temperature at39", or better, at 55-60°, peptone seems to yield nearly one-tenth ofits weight of sugar. JN. W.Iron in the Foetal Organism. By G. BUNGE (2eit.physioZ. Chem.,17, 63--66).-1n two former communications (Abstr., 1889, 789 ;this vol., p. 516) i t has been shown that certa8in organs of the new-born mammal contain a store of iron, which is gradually used up inthe formation of the iron-containing principles of the body, the milkcontaining insufficient iron for the purpose. In young guinea pigsthis is not so marked, as very soon after birth their milk diet issupplemented by vegetable food rich in iron. Young cats, dogs, andrabbits, Iive longer on milk only. The rabbit is born blind, andotherwise immature, the guinea pig is covered with warm fur, and itseyes are open.One must, therefore, for fair comparison, examinethe guinea pig in a condition corresponding to that of the new-bornrabbit; that is, the fetal guinea pig must be removed from theuterus. It is then foufid that the theory is fully confirmed; theguinea pig, like the rabbit, has the highest relative amount of ironin its body at the time of birth ; the amount of iron is directly relatedto that in its food. W. D. HPHTSIOLOCI'lGAL CHEMISTRY. 1503Iron in the Liver. By G. BGNGE ( Z c i t . physiol. Chem., 17, 78-82).-In order to estimate the iron in the liver i t is, above all things,iieressary to have it blood free. This can only be done during life ;salt solution being passed through a cannula into the portal systemin anzsthetised animals ; the fluid is allowed to escape by the hepaticartery and vena cava inferior. The liver is removed and weighed,but only tbose portioiis which are perfectly pale, aud give no redcolonr after soaking in distilled water, are takeii for iron analyses.The amount of iron in milligrams per 100 gi'anis of liver in 10analyses (dogs and cats) were, 8.7, 1.0, 2-5, 2.6, 4.7, 4.7, 35.5, 5.2,7.0, 6.4.The high number, 35.5, W-BS in a very young animal, andcontrasts forcibly x i tli the rest, which were full grown.

H.Influence of Hot Baths on the Excretion of Nitrogen andUric Acid from the Human System. By E. FOKMANEK (Mo?Iu~s?L.,13, 467-481).-A single hot air or rapour bath does not cause anyperceptible change iu the excretion of nitrogen from the system, butif baths be taken on two corisecutive days, the excretion of nitrogenis found to increase on the second day, the increase continuing untilthe day following.The same thing holds also for the excretion ofuric acid. A temporary raising of the temperature of the body is,apparently, therefore, of little effect in this respect, it being neces-sary to maintain the action for some time before change is noticed.H. C.The Excretion of Nitrogen in Urine. By G. GUXLICH (Zeit.physioZ. Clzem., 17, 10--14).-Aiialytical data of a large number ofexperiments with urine are given in tables or expressed in cnrves.The points investigated were, (1) the total nitrogen : (2) the nitrogenin ammonia ; (3) the nitrogen left after precipitating by phospho-tungst,ic acid ; (4) the nitrogen of the so-called " extractives," that is,(1) - (2 + 3).With different diets, there mere found :-1.A relatively large increase and diminution of uyea with meatand vegetable food respectively.2. A relative increase of ammonia with vegetable food. There wasno change with animal food only.3. A large relative diminution and increase of extractives withmeat and vegetable diet respectively.A large nnmber of morbid urineR were also examined. I n febriledisorders there was a relative lessening of urea, an increase of ex1504 ABSTICAOTS OF OHEMIOAL PAPERS.tractives and of ammonia. In diabetes, all cases showed a relativelyhigh percentage of ammonia ; the amount of extractives and urea,as in healthy persons, varied with the diet.I n cases of liver cirrhosis, severe anzmia, and heart failure, therewas reiative lessening of urea, and increase of ammonia and extrac-tives.I n cases of kidney disease, there was a lessening of total nitrogen,and an absolute and relative increase of ammonia.I n uracmia, theurea excreted varies but little, but the extractives almost disappear :these substances appear t o be retained in the tissues. The ureaexcreted in kidney disease is relatively great.I n healthy and sick persons, the excretion of extractives is increasedif the body weight falls. It appears that the katabolism of tissueelements yields more extractives relatively than the decomposition ofnitrogenous food stuffs.Reducing Agents in Normal Human Urine. By G. S.JOHKSON (Chem. News, 66, 91) .-In correcting a misquotatlon iirNeubauer and Vogel’s Brmlyse cles Harns, p. 57, the author points outthat, when removing reducing substances from urine by means ofmercuric chloride, he disposes of the excess of mercury by addingammonia solution cautiously until precipitation is complete ; under-these circumstances both the solution, and the precipitate whendecomposed by hydrogen sulphide under water, are free from sub-stances reducing copper oxide, He recognises that when hydrogensnlphide is used to remove the excess of mercury, a decidedly reduc-i n g solution is produced.W. D.H.D. A. L.Occurrence of Acetyl Derivatives in the Urine of Animalsafter Ingestion of Aldehydes. By R. COHN (Rer., 25, 2457-6470).-Some time since (JaffB and Cohn, Abstr., 1887,1032) it wasdiscovered that when dogs or rabbits are fed with furfuraldehyde, aPerkin’s synthesis takes place, the furf iiraldehy de condensing withacetic acid to form furfuracrylic acid, which leaves the body in com-bination with glycocine, occurring as furf uracryluric acid in the urine.Attempts to discover analogous syntheses have failed.Benzaldehydeis not converted into cinnamic acid ; indeed, the latter substance, ifintroduced into the crganism, leaves it as benzaldehyde. Thiophen-aldehyde, administered to a dog, left the system as thiophenuric acid,partlly as such, and partly i n combination with carbamide. Nothienglacrylic acid was found ; and indeed this substance, when ad-ministered t o a rabbit, was fourid to undergo decomposition, leavingthe organism as thiophenuric acid. Further, in the cases of acet-aldehyde, paraldehyde, chloral hydrate, and vanillin, no condensationwith acetic acid was observed.I n some further experiments, however, with the nitrobenzaldehydes,it was found that acetic acid does play a part in the reaction, formingacetamido-derivati ves.When a dog is fed with metanitrobenzaldehyde, the latter is con-verted into nletanitrohippuric acid, and leaves the organism partlyas such, partly in combination with carbamide. If, however, rabbitPHYSIOLOGICAL OHEMISTRY.1305are experimented on, in addition to metanitrobenzoic and metanitro-liippuric acids, metacetamidobenzoic acid is found in the urine. Ifmetamidobenzoic acid is administered, no metacetamidobenzoic acidis formed, but uramidobenzoic acid.Orthonitrobenzaldehyde, administered to rabbits, is for the greaterpart, destroyed ; n small quantity is converted into orthonitrobenzoicacid.When paraiiitrobenzaldehyde is administered, a substance of thecomposition C16H14N207 makes its appearance in the urine.Thissubstance forms colourless; spherical aggregates of small needles,fantastically disposed a t the edges; it is rather insoluble in ether,soluble in boiling alcohol, and very slightly soluble in boiling water.It possibly has the constitution COOH-C,H,*N0,,NHAc*C6H4*COOH,beiog a molecular compound of paranitrobenzoic and paracetamidc -benzoic acids. When distilled, it gives off acetic acid ; if heated at 150"in a sealed tube with hydrochloric acid, or when boiled with hydro-chloric acid or barium hydroxide, it yields paranitrobenzoic acid; whilstyeduction with ferrous hydroxide converts it into paracetamidobenzoicand paramidobenzoic acids.I t can be synthesised by mixing hot solu-tions of paranitro- and psracetamido-benzoic acids, but is not formed bythe loss of a molecule of water between these, for in that case t h eformula Cl6Hl4N2O7 would require the presence of 1 mol. of water ofcrystallisation, whereas it loses no water when heated att 150", althoughi t volatiiises to some extent. I n solution, it dissociates ; the solutiongiving R lowering of the freezicg point corresponding to a mixture ofit,s two constituents. The solid substance is not, however, a meremixture, but a true chemical compound, and that for the followingI-easons.It is formed when solutions of its two constituents aremixed, in proportions of either 1 : 2, 1 : 1, or 2 : 1 ; it cannot beseparated into its constituents by fractional crystallisation, and whenits silver salt is precipitated in three successive fractions, the thirdfraction contains the same percentage of silver as the first, It is amolecular compound of a novel and interesting type. Probably thetwo molecules are united by their nitrogen atoms. C. F. B.Sulphates and Ethereal Hydrogen Sulphates in the Urineduring Diarrhoea. By S. T. BAR~OSCHEWITSCH (Zeit. physiol. Qhem.,17, 35-57).-B1u11 analytical details support the following conclu-sions :-The absolute and relative quantity of t'he preformed sulph-ates ( a ) and the ethereal hydrogen sulphates ( b ) are smaller duringdiarrhmx than normal, but the fractionsI n calomel diarrhcea, the disinfection produced by t'he drug lessensb ; this is not true for all purgatives, as castor oil increases b andlessens the fraction a -- '. From this it appears that there are twoclasses of purgatives, those which disinfect the intestines and thosewhich do not.The diagnostic importance of such observations is not great, exceptthat careful experimentation might sometimes lead to the detection ofor ' are smaller.1506 ABSTRACTS OF CHEMICAL PAPERS.those cases of malingering when diarrhaa has been artificially pro-duced. w. D. H.Hzematoporphyrinuria. By A. E. GARROD (J. Pathol. and Bac-teriol., 1, 187--197).-Small quantities of hamatoporphyrin arepresent in healthy urine.Increase occurs in many diseases : someinfective, others (as many cases of liver disease) not so. Antlemiadoes not constantly increase the amount, and in febrile diseases, theamount is not proportional to the severity of the attack.W. D. H.Physiological Action of Pentoses. By W E BSTEIN (Vi~chow’sArchiti, 129, 401-412) .-In view of the dieting of diabetic patients,it is necessary to investigate the physiological action of various formsof sugar; and the present research relates to the two penta-glucoses or pentoses (C‘,H,,O,), xylose and arabinose.These substances reduce Fehling’s solution, Nylander’s reagent,and form osazmes with phenylhydrazine. They also give the fol-lowing characteristic reactions :-(1.) By distillation with hydro-chloric acid they yield furfuraldehyde.(%) A solution mixed withan equal volume of concentrated hydrochloric acid and then with a,solution of phloroglucinol in equal parts of hydrochloric acid andwater, and warmed, gives a beautiful red colonr, which gives a darkabsorption band to the right of thc D line. Most urines give a deepcolour with these reagents, but the characteristic absorption band isnot shown.Xylose, dissolved in water or coffee, or in the solid state mixedwith the food, was given to various people. The amount in the urinewas estimated by Fehling’s solution (1 milligram xylose = 1.9 milli-grams copper), after any glucose that might have been present hadbeen removed by fermentation with yeast.It appears that xylose i snot assimilated, even when taken in very small quantity, and i t can berecognised in the urine within an hour or two after the administrationof 0.5 gram. This is true both for healthy and diabetic persons. Onereceived 25 grams of xylosa; in the next 24 hours 9.5 grams wereEound in the urine, and the excretion continued for the two follom-ing days.Arabinose (1 milligram = 1.95 milligrams copper) gave practicallythe same results.The use of fruit, such as pears, that contain pentosanes, the niotliersubstances of pentoses, may give the characteristic tests for pentosesin the urine. It is, of course, important not to confound such atemporary condition with diabetes.Pharmacological Investigations of Ketones and Acet-oximes.By H. PASCHKH and 3’. OBERMAI’ER (Monatsh., 13, 451-466) .-In their physiological effects, the ketones of the fatty seriesresemble the alcohols, producing narcosis and decrease of bloodpressure. I n strength of action, the different ketones are by no meansequal, t h i s property being chiefly determined by the nature of t h ealkyl groups present in the molecule. l n the case of the acetoximes,it was at first supposed that these would probably decompose in theW. D. HVEGETABLE PHYSlULOOY AND AGHIGULTURE. 1507system with separation of hydroxylamine. Their effect, however,is found to be totally different from that of hydroxylamine and tobe generally similar to that of the alcohols aiid ketones. Theirstrength of actioa, as in the case of the ketones, depends on thenature of the alkyl groups which they contain, and it may be saidgenerally that the conversion of a, ketone into the acetoxime doesnot cause any marked change in its physiological action.Physiological Action of Sulphonal.By W. J . SMITH (Zeit.physiol. Chem., 17, 1--7).-Large doses of sulphonal do not influencethe excretion of urinary nitrogen. There is also no effect on thesulphuric acid. Kast (Bedin. klin. Woch., 1888, No. 16) states that thegreater part of the sulphonal given does rot enter the urine un-changed, but as a readily soluble organic sulphur compound, It wasfound, however, in the present research, that in dogs, after 3-gratndoses in solution, small quantities of unchanged sulphonal passed intothe urine. JaffQ (Deutsch. med. JVoch., 1891, No.21) and Jolles (Phaym,Post, 1891, No. 52) have also found the same in human urine.What are the compounds in which the greater part of the sulphonalpasses into the urine ? There are t>wo possibilities : it is either ethyl-sulphorLic acid, formed from the easily oxidisable ethylsulphinic acid(HSO,*C,H,) ; or szdphoacetic acid ( SOJ3*CH2*C00H). In ordeyto settle the matter, these two compouiids were given to dogs andmen, and the urine examined.After doses of 6 grams of potassiuni ethylsulphonate, the sulphuricacid was not increased, and the salt given was separated from t h emine, although in too impure a form for analysis.The same dose of sodium sulphoacetate lessened rather than i n -creased the urinary sulphurio acid, although the total sulphur in theurine was double, showing that the salt had been absorbed. Thebarium salt was crystallised from the urine. Jn urine, after the useof sulphonal, however, no trace of bayium sulphoacetate was obtain-able ; the chief end product of the sulpbonal thus appears to be ethyl-sulphonio acid. W. D. H.H.

Peas assimilate considerable quantities of atmosphericnitrogen in good soils, and symbiosis increases this faculty. Cloverbehaves like peas.Not only does Frank hold that these leguminous plants mayassimilate free nitrogen without the development of any root tubercles,but he has also obtained fixation of nitrogen, although to a less extent,with cultares of oats, buckwheat, spinneg, asparagus, and colza, whichnever show any development of root nodules.Fixation of Free Nitrogen during Vegetation.By E. BREAL(Ann. Ayrolz., 18, 3G9--379).-The author has grown plants of cressin river sand, watered with a solution of potassium chloride withcalcium phosphate in suspension and a little added magnesiumsulphate, under conditions which demonstrate the fixation of atmo-spheric nitrogen by the combination, A growth of four months in6.3 kilos. of the soil showed gains of nitrogen in the azrinl parts ofthe plants of 0.305 and 0.290 gram, and in the soil and roots of eachpot of 0.339 gram N.The seeds of the plants grown in this way werelighter, and contained less citrogenous matter than the seeds sown,which, of course, had been grown in a nitrogenous soil.J. M. H. M.J. M. H. M.Sodium as a Plant Food. By A. ATTERBERG (Ex@ Stat. Record,3, 554; from Deut. Znndw. Presse, 1891, 10Y5).-1ii the author’sexperiments, black Tartar oats were grown in quartz sand andwatered with nutritive solutions containing hydrogen potassiumphosphate, rcagnesium sulphate, and potassium, sodium, and calciumnitrates. Different amounts of potassium were replaced by equivalentamounts of sodium and of calcium respectively. The results show afalling off in the yield of oats when t h e supply of potassium wasdiminished, but the falling off was much less in the sodium seriesthan in the calcium series.Thus, with 9.42 grams of potassium, thesodium series gave 141, and the calcium series 142, grams of oats;with 5-65 grams of potassium, the sodium series gave 134, the caiciumseries 112 grams of oats; with 1.88 grams of pofassium, the yieldswere 112 and 75 grams respectively. Sodium may thus be of greatimportance where potassium is deficient, and the large amount ofsodium in many of the Stassfurt salts is no longer to be considered asuseless. N. H. MVEGETABLE PHYSIOLOGY AND AQRICULTURE. 1,509Distribution and Condition of Iron in Barley. BJ P. PETll'(Compt. rend., 115, 246-248).-When barley is treated repeatedlywith a dilute solution of hydrochloric acid in alcohol, only a minutequantity of iron is dissolved, and i t follows thnt practically the wholeof the iron is present in the form of nucle'in. An investigation of thedistribution of the iron in various parts of the grain shows that thedry embryon contains 0.11 per cent., the integument 0.097, and theproteids 0.002 per cent.During germination, the quantity of iron present in the form ofnuclejin varies but little, although the proportion of iron diminishes.I n the early stages of germination, the iron in the embryon is suffi-cient, for the requirements of the plant, and none is withdrawn fromthe integument or the prote'ids.C. H. B.Oil of Cinnamon. By J. WERER (Arch. Pharm., 230, 232-248).-The author has examined the oil from the leaves of Cinnamomumceylaniczcm, Breyn., arid substantially confirms the results of Stenhouse(Annulen, 95, 103) and Schaer (Abstr., 1882, 1300).The oil wasobtained through Schuchardt, of Gorlitz, from Port Louis, SeychellesIslands, and was guaranteed pure. I t had the colour and odour ofoil of cloves and a burning taste; its sp. gr. was 1.0552 a t W5",For the most part it consisted of eugetiol, but contained, in addition,small quantities of cinnamaldehyde and of terpenes. Attempts toidentify pinerie and cirieole among the latter were unsuccessful,Benzoic acid, also, could not be detected.Another oil was examined, purporting to be obtained from theroots of the same plant, and procured from Schimmel, of Leipsic.Since the completion of the research, however, this firm have throwndoubts on the genuineness of this oil, suspecting it to be derived fromthe leaves.It had the colour and odour of oil of cloves, and its sp.gr. a t 19" was 1.0411.. This oil also consisted mainly of eugenol, butcontained also safrole, small quantiries of benzaldehyde, and a con-siderably larger amount of terpeiies than the first oil examined.C. F.

A. L.excluded. A. Hi. L.Iodometry. By T . SALZER (Zeit. anaZ. Chem., 31, 376-381).-The author, whilst admitting with Topf (Abstr., 1887, 68&> that theaddition of ammonium carbonate to thiosulphate solution alters itsrelation to iodine, maintains that the addition has a marked effect i npreserving the streiigth of the solution unchanged. A solution towhich 2 grams of ammonium carbonate per litre had been addctl,proved, after keeping for five years without special precautions, tobe of exactly the same strength as one freshly made without ammoniafrom the same specimen of thiosulphate.On t h e other hand, a newsolution containing carbonate required a larger quantity of iodine t ogive a yellow colour, and this colour was not permanent until 20 percent. more iodine had gradually been added. The addit’ion of starchseems t o prevent the disappearance of the excess of iodine, and t h efailure of Mohr to notice these anomalies probably arose from hisuse of strongly acid starch as indicator. The subject still needs in-vestigation. The author advocates the use of chemically pure thio-Eulphate, and shows that the methods of testing employed by Topf(Abstr., 1887, 997) are riot trustworthy. Owing to the solubility oElcarium sulphate and carbonate in thiosulphate solution, 2 per cent. ofsodium sulphate or carbonate may be present without producing anyturbidity with barium chloride.It is necessary first to oxidise thethiosulphate (together with any unsaturated sulphur salts) by a smallexcess of pure iodine befoi-e testing with barium nitrate. Calciuinsulphids and chloride should also be looked for. A solution madefrom the pure salt may be accepted as a standard as long as it givcs(after addition of iodine) no turbidity with barium nitrate.Detection of Chlorine and Bromine in the presence ofIodine.

G.T. M.Estimation of Nitrogen in Organic Substances. By W. F.K. STOCK (dnalyst, 17, 109-112, 152--153).-The process to bedescribed must not be considered to be a mere modification ofKjeldahl’s method. In the latter process, the substance is oxidised,and its nitrogen converted into ammonia, by the sole action of boilingsulphuric acid, and only in the last stage a little potassium per-manganate is added, and even this addition is not advisable. Theauthor oxidises the substance with a mixture of sulphuyic acid andmanganic dioxide, and so succeeds in completely converting itsnitrogen into ammonia.From + tto 1 gram of the substance is mixed in a conical flask orsmall beaker with 10 C.C.of snlphuric acid (sp. gr. 1.84) and 5 gramsof pyrolusite, which should be fine enough, but yet not too fine. Theflask is heated until the contents assume a dark-greeu colour, whicANALYTICAL OHEMISTRY. 1.51 7indicates the end of the reaction. After cooling, water is added, andthe contents transferred to the appatrstus. An excess of sodiumhydroxide is added, and the ammonia is distilled off and titrated inthe usual way.The apparatus, shown in the accompanying figure, consists of acopper boiler of 600 C.C. capacity, closed b,y a screw cap and india-rubber washer. This cap carries a tapped funnel for the introduc-tion of the soda solution, and B wide evolution tube to serve as areflux tube, in case of sudden frothing. The tube is closed by anindiarubber stopper carrying a tube bent at such an angle as topermit of its passing down the centre of a Wurtz flask,.which servesas a washing flask for the vapours from the copper boiler. Bothboiler and flask are provided with burners, and both must be keptboiling throughout the experiment. The Wurtz flask is in turnconnected with a 14-in.

The only precautions required during the combustion are toavoid too tnmultuous an evolution of gas, to cool well the vessel inwhich the ammonia is absorbed by acid, and to continue heating thetube until the last trace of water has distilled over, which requiresabout as long (25 minutes) as the combustion itself. For the titra-tion, fluorescein or lacmoid is used, in order that the hydrogensulphide present may have no influence.This method cannot beused for nitro-compounds, for nitrites, or for thc nitrates of pyridiiieand chinoline.

Iron alone reducesnitric acid i n the cold very slowly and imperfectly, butt when coatedwith copper, its reducing action is complete and rapid. Nitrites,and even a solution of nitric oxide in a ferrous salt, are similarlyreduced to ammonia. 1 mol. of a nitrite [RIL'NO,) causes a deficit of8 atoms of hydrogen, and it is remarkable that whereas in estimatingnitrates ithe presence of chlorides in any considerable quantity causesthe reduction to be incomplete, witjh nitrites the results are perfectlycorrect even when hydrochloric acid alone is used.The injuriouseffect of the presexlce of chlorides on the nitric acid estimation can,however, be completely got rid of by adding some co,pger sulphate tothe mixture of acid and nitrate which is to be introduced into thereaction tiask, and warming .to 60".

Bg A.WESTBERG (Zeit. anal. Chem., 31, 494--486).-The action of carbonbisulphide on the blood consists in the formation of methzemoglobin,with disintegration of the corpuscles. The action of xanthic acid isdue solely to the carbon bisulphide liberated by its decomposition inthe body.Jn cases of poisoning by carbon bisulphide, that substance can bedetected in the blood.About 12-15 C.C. of the blood is drawndirectly from a vein into a flask, where it is mixed miih half itsvolume of water, and distilled under reduced pressure in a stream ofcarbonic anhydride o r hydrogen. The carbon bisulphide can be re-cognised in the distillate by treatment with an ethereal solution oftriethylphosphine. This reagent will detect as little as 0.54 milli-gram of the bisulphide. By converting the bisulphide into potassiumxanthate, evaporating to dryness i n a vacuum, and testing the residuewith sulphuric acid and ammonium molgbdnte, a red colour is pro-duced, with as little as 0.667 milligram.The thiocyanate reactionseems to reach its lower limit at 1.05 milligrams.31.

In 1887, the practice was commenced of addingmagnesia, with or without lime, i n order to obtain greater alkalinitywithout increase of total ash. The author has employed the follow-i n g process for the estimation of these alkaline earths :-About5 grams of the guncotton weighed in a roomy platinum cruoiible ismoistened with a mixture of equal volumes of alcohol and ether,which, after having been saturated with paraffin and filtered, ha,,been mixed with one-fourth of its volume of water.Some fragmentsof solid paraffin are added, and the ether is set on fire. The obliquelyplaced crucibIe is rotated so Cha,t the guncotton may absorb theparaffin uniformly. The partially charred residue is then rubbeddown with ft rounded glass rod, and the crucible is covered andliented for 15-30 minutes over the blowpipe, occasionally removingthe lid. The ash is weighed, then washed out into a porcelain basin,and heated to YO" with a measured excess of N/10 hydrochloric acid.The lime and magnesia dissolve along with traces of ferric oxide andalumina sufficiently large to interfere with the dii-ect titration of theexcess of acid.

After adding I0 C.C. ofpure nitric acid, previously diluted with 10 C.C. of watep, the mixture isheated on the water-bath until the yenow colour of the precipitatehRs changed to a n orange-red. The lead iodide soon dissolves, andiodine is set free, which is expelred by adding boiling water andevaporaking for some time on the water-bath, water being addedfrom time to time. The precipitate IS tBen pure silver iodide, and,according to the aluthors, is best collected on a weighed glass-woolfi-Et8eT, and dried at 110".The presence of copper, cadmium, and bismuth does not interfere,bnt if mercury ia present the silver iodide retzins mercuric iodide.If the silver is present only in smaII quantities, for instance, in thecase of argentiferous galena and pig-lead, as much as 10 or 50 gramsof the sample must be operated on.The authors dissolve the metal ina mixture of nitric and tartaric acids, dilute to 300-500 c.c., add 10C.C. of a 10 per cent. solution of potassium iodide, which is Sure to besufficient to precipitate all the silver, and then proceed as described.By L.

The apparatus consists ofsix glass pieces united by rubber tubes of Ei mm. bore and 5-7 mm.thickness, Tile first vessel, C, is a mercury reservoir ; then followi n series three tubes of pipette forin, C’, A, and B, of which A, of 250to 500 C.C. capacit{y, is the collection vessel for the water.

All the rubber tubes connecting thesevessels are closcd by conipression clips.The tube B is connected to theside branch of a tiibe D, of the form of a gas burette, of which boththe side and upper limbs are furnished with good glasg stopcocks. Thelower end of D is joined by a rubber tube, 1 metre in length, to Atubular mercury reservoir E, whilst the upper limb is ppovided witha gas delivery tube leading to a mercury trouqh. To collect thewater, A is placed in a vertical position and filled with mercury byinflux from C. The upper end of A is then connected by tubing withthe water supply, and the mercury is allowed to flow back into C.The water is thus transferred without contact with air. A is iiowplaced in an oblique position; B is attached, and by alternatelylowering and raising the reservoir E, with suit:tblc manipulation oANALYTICAL CHEMISTRY. 7 527t h e stopcocks, the tube B is exhausted of air and filled with mercury.The compression clips are now all opened, and the water in A jsvigorously boiled, t h e reservoir C being at such a level t h a t t h epressure in A is 5-10 cm.below that of the atmosphere. After fiveminutes' boiling, the loner clip is closed, and the g:ts in B is pumpedoTer into D and expelled into a tube standing in the mercury trough.The clip is again opened and the boiling repeated a s loog as any tracesof gas are obtained.

J., 14, 300--310).-1t is -found t h a t the Nesslerisedammonia standard of colour, although the best hitherto used, is ob..jectionable on account of the change in the standard colours withslight variations in snar,ipulation, the colours of the lower standardsdepending quite a s much on the quantity and quality of the Nesslerreagent used as on t h e ammonia. Further objections exist in thefacts that the nurnibei*s expressing the colours are not directly pro-portional t o the colours themselves, and t h a t waters having coloursless than that of Nesslerised distilled water find no place in itsscale.Standard eolours prepared from a mixture of solutioas of platinumand cobalt chlorides are recommended, as the colour of such solutionsis, within wide limits, independent of acidity and temperature, andtlie standards are quite stable even in direct sunlight when contain-ing a moderate amount of hydrochloric acid.The colour of the standards can be made to match t h a t of naturalwaters, allowing more accurate comparisons than are possible withNesslerised ammonia.The figures obtained a r e directly proportionalto the actual colours, W. T.Volumetric Analyses by rn eans of Potassium Ferrocyanideor Ferricyanide. By C. LUCKOW (Chew. ,&it., 16, 164-165 ; 835-838).--The author (compare this vol., p. 1129) recommends that theformula of potassium ferrocyanide should be doubled. l h e standardsolution should therefore be made by dissolving 4 2 2 Prams of t h e saltin 1 litre of water (a F/20 solution).The ferricjanide solution ismade by taking 32.9 grams of potassium ferricyanide in 1 litre ofwater. The ~olutions may, if desired, be diluted t o any given,strength, so that, for instance, 7, C.C. will show exactly 0.005 of metal.Both solutions are best preserved i n brown glass bottles, and, accord-i n g to Moldenhauer, the feryocynnide should Ise made alkaline topreserve it better. The general properties ~f the ferrocyanides andferricyanides of the heavier metals a r e a s follows :- They are colouredcompounds, which are mostly insoluble in water, and readily depositfrom saline solutions, but remain more o r less suspended in pure water.Acids, particularly hjdrochloric acid, slightly increase the solubility.At first no diEculty is experienced in tiltering, but as soon as theattempt is being made to wash with pure water, some of the15-28 ABSTRACTS OF CHEMICAL PAPERS.have a, tendency to pass through the filter.After prolonged dryingat 60-70", the granular pi-ecipitates form brittle masses readilycrushed ; the more bulky precipitates look more like dried gluten.Some precipitates may be dried at 200" without undergoing anymarked decomposition ; others, for instance, those precipitated froman ammoniacal solution, sensibly diminish in weight. Some ferri-cyanides are decomposed at loo', whilst the manganese compoundactually begins to glow at that temperature. On ignition, andrepeated treatment with nitric acid, the metallic oxides are leEt.Theaction of ammonia is peculiar ; some compounds dissolve withoutdecomposition, but tin compounds gmdnally deposit the tin as hydr-oxide. Other metals, such as zinc, although their hydroxides aregoluble in ammonia, are precipitated from their ammoniacal solution.The author also calls attention to the various, in some cases impos-Hible, quantities of combined water which these compounds are sup-posed to contain, and recommends farther inrestigation in thisdirection.The reaction between potassium ferrocyanide and metallic solu-tions is not, however, always complete, and then in most cases theprecipitates contain more or less undecomposed potassium or am-monium ferrocyanide. When working with f erricyanide, the reac-$ion is generally more complete.The solutions should, therefore,always be checked with a known quantity of metallic salt; the titra-tions being effected under like conditions of reactions, &c. To showtahe necessity of this, the following results obtained by the author maybe quoted :-1. Action of potassium ferrocyanide on zinc : 1 C.C. of a N/20 solu-tion = 0.00975 gram of zinc in acid solution, 0.0381 gram inneutral solution, and 0.13 gram in ammoniacal solution.2. Action of potassium ferricyanide on cobalt : 1 C.C. of N/20 solu-tion = 0.0088 gram of cobalt i n neutral or acid solution, and 0.0103gram in its ammonium carbonate solution.Similar results were obtained with several other metals.Estimation of Iodoform.By H. D. RICHMOND (Analyst, 17, 7).-When iodoform is hezted with alcoholic soda, a somewhat complexreaction takes place, but its 70 per cent. of iodine is practically con-verted into sodium iodide. On this fact, the author has based thefollowing method for the testing of commercial iodoform.About 0.15 gram of the sample is dissolved in alcohol, an excessof alcoholic soda is added, and, after about 10 minutes' digestionnear the boiling point of the alcohol, the excess of spirit is evapo-rated. The residue is taken up with water, slightly acidified withdilute nitric acid, and again iieutralised by a small quautity ofcalcium carbonate. The solution is then titrated with a weakstandard solution of silver nitrate with potassium chromate as indi-cator.The method does not take more than half an hour to per-form. Should the iodoform be obtained in ethereal solution, as, forexample, in the estimation of acetone, the ether need not be evapo-rated, but can be mixed directly with the alcoholic soda. The testanalyses are very satisfactory,L. DE I(.L. DE I(ANALYTICAL CHEMISTRY. 1529The Oxidation of Alcohol by Permanganate. By R. BEKE-IIIKT and J. NEUD~RFER (Chenz.

DE K.Estimation of Glycerol i n Wine. By G. BAUMERT (Arch.

The wine (50-100 c.c.) is evaporated in a dishwith precipitated calcium carbonate (1-2 grams) to about one-half,and introduced into the wide limb of the distillation flask, which isthen heated until no more mater condenses in the upper part. Super-heated steam is now admitted, and the distillate collected in a 200 C.C.flask, to which volume it is subsequently diluted. Potassium oydr-oxide (10-12 grams), free from oxalate, is dissolved in the dilutedistillate, and, after cooling, a cold saturated solution of potassiumpermanganate is added in excess. The mixture is boiled for sometime and, after half an hour, a stream of sulphurous anhydride (fromhydrogen sodium sulphite and sulphuric acid) is passed through ituntil the liquid is colourless, and all separated manganese oxides havedissolved.Acetic acid is next added, all sulphurous anhydride ex-pelled by boiling, and t$e oxalic acid precipitated by calcium chloridesolution. The precipitate will contain calcium sulphate, and cannotbe weighed directly; i t is washed with hot water, decomposed bysulphuric acid, and titrated with potassium permanganate solution.90 parts of oxalic acid are equivalent t o 92 parts of glycerol.Planchon’s method, whereby the distillate is oxidised completelyby acid potassium permanganate solution, and the resulting carbonicanhydride weighed, does not yield such good results as the methoddescribed.

H.Improvement in the Method of Estimating Aldehydic andKetonic Oxygen. By H. STRACHE (&!lo,izatsh., 13, 299-315 ; corn -pare Fischer, Bey., 17, 572).-The author has previously (this vol ,p. 546) described a, method for the estimation of aldehydic and ketonicoxygen, i n which the substance under in\-estigation is added to anexcess of phenylhydrazirae, whereby a hydrazone is formed, and theexcess of phenylhydrazine is dterwards determined by measuringthe nitrogen evolved on treating it with hot Fehling’s solution. Tb.emethod is, however, liable to two sources of error ; one, due to t h efact that, under some conditions, Felaling’s solution and phenyl-hydrazine may react with formation of aniline, lowering the results ;the other raising them, owing to the tension caused by the presenceof a variable quantity of benzene vapour in the gas.To eliminatethese errors, the author has reerraiiged the apparatus employed i nsuch a way that the solution OE the compound under investigation isallowed to fall into hhe hot Fehling’s solution ; and he passes severaldrops of benzene into the measnring tube containing the nitrogen,the volume of the gas being afterwards corrected for the tension ofthe vapours of both water and benzene. Under such improved con-ditions, constant lout, owing to the imperfect displacement of ail*,somewhat too high results are obtained.The further necessarycorrection was determined by conducting experiments in blank, anci,after making due allowance, the results mere satisfactory. Acetoneand many other compounds gave numbers which accurately ngreetlwith the calculated values, but anomalous results were obtained witltbenzile and benzophenone. Both of these, when alcohol was employedas a solvent, gave numbers corresponding with only half the oxyge:ipresent in the carbonyl groups of the compounds.Estimation of Thiocyanacetone. By J.

Petrowitschinferred from this the absence of tartar, and assumed that the wholeof it had been precipitated by the 14-65 1-01s. per cent. of alcohol,under the conditions of long keeping in a, very cold cellar. In bothcases, however, a soft, slimy, brown precipitate was obtained. Ilithe author's case, this proved to be chiefly sugar, containing, however,tartar, the crystallisation of which was prevented by the syrup.Aftercomplete fermentation of the wine, a crystslline precipitate of tartarcould be obtained, but none of the slimy matter. The limit ofalcoholic strength a t which a wine cannot retain tartar is, therefore,8. B. A. A.M. J. S1.532 ABSTRACTS OF CHEMICAL PAPERS.above the 14.8 vols. per cent. present i n this specimen. Since nquantitative experimeiit with an artificial sweet wine showed thatafter complete fermentation the whole of the tartar added could berecovered, it is recommended that sweet wines should be fully fer-mented beEore precipitating with ether-alcohol.To the assertion of Dietzsch that a wine from which no tartar canbe precipitated in the course of 24 hours must be artificial, it mayfurther be objected that genuine wines, which have been over-plastered, will have lost the whole of their tartaric acid as calciumtartrate.

A mixture of equal parts of thesolutions gaye the strychnine reaction very clearly, but the atropinereaction not a t a l l ; a mixture of 1 of strychnine with 3 ofatropine gave the strychriine reaction, but not that of tttropine; amixture of 1 part of strychnine with 4 of atropine gave indistinct,reactions f o r both alkalo‘ids; R mixture of 1 oE strychnine to 3 ofatropine gave a, momentary atropiiie reaction ; the charact eristioviolet coloration is, however, immediately superseded by a redclishtint.Vitali’s reaction WRS not cIeai*ly obtained until a t least 9 partsof the atropine solution were added to 1 of sti~ychnine. It Burtherappeared that a solution of strychnine too dilute to give the charae.teristic reactions of that +lkaloid may effectually obscure the atropinereaction ; thus 1 drop of the 3 per cent. strychnine solution dilutedwith 10 drops of water scarcely yields the spyrhnine reaction ; onadding 4 drops of atropine solution to this, no reaction for atropinecould be obtained.A piece of meat injected with 0.05 C.C.OP a 3 per cent, solution ofeach of the alkaloidg, and extracted by the S t a s 4 t t o process, yieldeda b.arely sensible strychnine reaction aud no trace of atropine.Finally, on injecting n mixture of 3 parts of the 3 per cent. strych-nine solution and 1 part of the atropine solution into a, frog, para-lysis of the lower limbs and a great angmentation of the nervoussensibility ensued ; on introducing the mixture into the eye of a dog,distinct mydriasis m RS observed in fifteen minutes. It thus appearst h a t in cases of poisoning by atropine, the physiological evidencemay be conclusive when the chemical tests yield doubtful resiilts.C. F. B.Detectign of Atropine,S. B. A.

Some of the liqdid is filtered, and 50 c.c, of tbefiltrate evaporated i n tt platinum dish, containiug a knowfi weight ofdry sand. Pure coffee, when treated in this mariner, gives from20 to 30 per cent.of extract only; some coffee substitutes yield asmuch as IS per cent.Approximate Zhtitnation of Adlllteratidn of E srtih-nut Cakeand Meal, By L, HILrmx (Landtu. Versuchs-&at., 40, 351 -355).-The substance (about 0.2 gram) is placed on an inverted plate and com-pletely moistened with t8inctdre of iodine. After a f e w niinutes, themeal is distributcd over the whole surface by means of a jet of waterfrom a wash-bottle. The liquid must still contain iodine, aud i R madeclear by the addition of a few drops of alcohol. The water is nowdrawn off, aid the substnhce air dried 2nd placed on green paper.By means of a lens o€ lorn power, the particles of cake which areblackened by the iodine are readily sepai4ated from the poppy seeds ;the separated pm'tions are then weighed, I n an experiment madewilh known quantities, 10.64 per cent.of popps seed wag found insteadof 10 per cent. I n this case, the particles of €he ground cake wererather large, and the separation therefore easy, When there arefinely-powdered, dust-like pafticles, the separation i 8 more difficult.Afher treatment with iodine and dryirig, the sdbstance is sifted ina 0.25-mm. sieve and the separation in the coarse portion is made asusual. I n two check experiments, the results were within 5 per cent.of the actual amouht. The percentage of poppy seed in the portionpassing through the sieve may be determined by separating under amicroscope, but the amount is generally sinall, and may be judgedwithout actual separation.The method is quickly carried ont, and is :ilpplicable not only in thecase of adulteration with poppy seed, but in nearly every case, as thesubstances uged for adulteration are dearly all fr'ee from starch,By C6 W.HEATON and S.
