581 Organic Chemistry. Double Salts of Silver and of Mercury containing Cyarnogen. By F. W. SCHMIDT (Xeit. anorg. Clrem., 1895, 9, 418--433).-Long, well-developed crystals are obtained when ammoniscal mercuric cyanide solution is allowed to remain for a considerable time at low temperatures. The compound is unstable, and at the ordinary tem- perature dissolves i n the mother liquor, crystals of ammoniomer- curic cyanide, Hg(CN)2,NH3, being formed; this has been pre- viously prepared in a different manner by Varet. Silver nitrate solution, when mixed with saturated mercuric cyanide solution, gives a sparingly soluble, crystalline, additive compound, Hg ( CN) ?,AgN03,2 HzO, which explodes when heated, but with more dilute solutions, or in presence oE nitric acid, no precipitate is formed.The compounds CN*HgN03,0H*HgN0,,10AgCN and OH*HaN03,20AgCN,5Ag20 + 7H20 are formed by mixinq a cold saturated ammoniacal mer- curic cyanide solution with 5 and 2 parts respectively of aqueous silver nitrate (10 per cent.) ; both are colourless, amorphous, pul- verulent, and sparingly soluble, but do not explode when heated. When the above solutions are mixed in the proportion of 1 : 0-3-1.2 of silver nitrate, pare silver cyanide is precipitated ; the further addition of silver nitrate canses a steady decrease of silver in the precipitates. The compound OH*HgN0,,AgCN,2Hz0 is obtained in crystals when ammoniacal mercuric cyanide solution (2.5 c.c.) is mixed with water (22.5 c.c.) acidified with nitric acid, and silver nitrate (100 c.c.) added ; it explodes violently when heated.By tho interaction of silver nitrate (7.5 grams), water (7.5 grams), concen- trated ammonia (30 c c.), and amruoniacal mercuric cyanide (20 c.c.), a compound, 20X*HgN03,2AqCX,4Ag20,3NH,CN, is formed, which crystallisea in plates, a.nd explodes Rlightlg when heated. The corn- pound 40H*H~CN,38~CN,'LA~*O,NLI,.CN + gHzO is formed like the preceding salt, if the silver nitrate is first precipitated with soda and the oxide dissolved in concentrated ammonia (50 c.c.). It is jellow, pulvernlent, arid somewhat unstable, but does not explode when heated. In all the above experiments, a cold, saturated solu- tion of ammoniacal mercuric cyanide, and a, 10 per cent. solution of silver nitrate, were employed. For the analysis of the above com- pounds, the mercury was determined as sulphide, the silver precipi- tated as chloride aiid cyanide, converted into sulphide by meam of ammonia and ammonium sulphide, and this into metal by cautious roasting.Potassium triiodide and silver nitrate in aqueous or alcoholic solu- tion give a dark brown precipitate, which probably consists of siloer tri- iodide, AgI, ; it is unstable, and readily dissolves in exvess of potassium triiodide.

Bimolecular Nitriles and their Derivatives. By ERXST V. MEI-ER (J. pr. Chem., 2895, [el, 52, 81-117 ; compare Abuti-., 1888, 802 ; 1889,113,114,683,684 ; 1893,i, 314).-On one occasion, when benzene was used instead of ether as a solvent in the preparation of diaceto- nitrile, the product was found to melt ak 74!-76', but after it had been kept at 80'for some time the melting point fell to that of diaceto- nitrile (52').This labile or a-diacetonitrile has been heretofore over- looked, because the product of the action of sodium on acetonitrile bas always been crystallised from boiling benzene, a process which converts the labile into the stable or B-diucetonitrile ; a-diacetonitrile me1t.s at 79-84', and is only about one-seventh as soluble in benzene as the stable form is, so that i t remains undissolved when a mixture of the a and p forms is tveated with benzene at 35'.In the following experiments, ,9-diacetonitrile was used. CIzZorodiacetonitriZe, NC1:CMe*CH2*CN (?), is obtained when diaceto- nitrile is treated w i t h chloride of lime and the product extracted with ether; it crystallises in white needles, and melts at 120'. The corresponding bromo-derivative is obtained as a white precipitate when diacetonitrile is agitated with excess of bromine dissolved in potash; i t crystallises in colourless needles and melts a t 123'. The lialogen cannot be removed from either compound by the ordinary reaqen ts. By heating diacetonitrile with ethylic chlorocarbonate at 100' and extracting the product with ether, a cmnpound, C,,HgN303, is dissolved, and a white salt is left. The former crystallises in white laminae and melts at 84".The latter contains chlorine, and when heated with dilute potash yields ammonia and a white rcsidne consisting of Holtzwart's base, CeH9N3 (Abstr., 1889, 683) ; this base is very sparingly soluble in water, ether, and benzene, but more freely in alcohol ; its pZatinochloride, (CeHgN3),,HJ'tCI,, crystallises in spar- ingly soluble, thin, bright yellow prisms. With acetic anhydride, the base yields a, monacetyl derivative, CsHeNsAc, which melts at 250°. The base is easily formed from diacetonitrile when this is placed under conditions favourable for the separatoion of ammonia, without acces8 of water, such, for instance, as when it is heated in boiling ethylenic bromide. An isomeride, melting at 157', is obtained when diacetonitrile is treated with carbonyl chloride and the chlorinated product is suspended in water made feebly alkaline with ammonia ; when heated with potash, it is converted into Holtzwart's base (m.p. 222'). By treatment, with nitrous acid, the isomeric base yields a compound, CeH8N20, similar in composition to that which Holtzwart obtained by heating dincetouitrile with water (Zoc. c i t . ) ; but it crystallises in small needles, decomposes above 260', and dissolves to the extent of 0.09 gram in 100 C.C. of alcohol (at lC;'), and of 0.042 gram in 100 C.C. of water (at lbo), whilst Holtzwart's compound ;:rptallises in long, lustrous needles, blackens at 230', and dissolves to the extent of 0.54 gram in 100 C.C. of alcohol (at 16O), and of 0.03 Neither compound combines in 100 C.C. of water (at 16').ORQANIO OHEMISTRY.583 with hydroxylamine or phenplhydrazine. The author discusses the constitution o€ the above substance, but arrives a t no conclusion. The hydrochloride, C4H6N,,13[CI, was obtained as an amorphous, white precipitate on passing hydrogen chloride into a benzene solu- tion of diacetonitiile. With carbanil in a benzene solution, both a- and /?-diacetonitrile yield three compounds : (1) needles, C,,H,,N,O, which melt at about 121-122" ; (2) laminse, which melt at about 150' and are also obtained when (1) is dissolved in hydrochloric acid and reprecipitated by an alkali; (3) a crystalline powder which melts a t 229' ; all three have the same percentage composition. Diacetonitrile reacts with cyanamide in warm water, with separa- tion of ammonia and formation of a condensation product, CgH,,N,O, which crystallises in needles and melts and decomposes at about 145' ; when heated with water, it yields the compound CsH8N,0.With diazobenzene chloride, diacetonitrile yields the phenylhydr- azone, NH1CMe.C (N,Hph).CN, which readily passes into cyunacetone- phenyZhydrazone, COMe.C(NaHPh)*CN ; the latter crystallises in yellow, silky needles, and melts at 166-167'. The two compounds combine to form an additive product, CmHI,N70, which crystallises in yellow needles and melts at 165". N,HPh:CMe*C( N,HPh).CN, was prepared ; it melts at 162-170'. Methylisolcazolenimide (Abstr., 1893, 3 14) and diazobenzene chloride yield the corresponding phenyl- hydrazone, N<CMe,C(N,Hph)> C:NH, which melts and partially decomposes a t 119O, and is converted by acid8 into Knorr's keto- methyli~oxazolone phenylhydrazone (Abstr., 1894, i, 372).When di~cetonitrile (1 mol.), dissolved in the smallest possible quantity of warm water, is added to a solution of hydrazine snlphate (18 mols.) in dilute ammonia, white needles (A) separate in the course of 12 hours ; if the mother liquor is neutralised with hydro- chloric acid, a further precipitation of white needles (B) occurs. These compounds, CsH1&14, are isomerides. The substance A melts at 85', and dissolves easily in dilute hydrochloric acid, but not in alkalis ; hot, strong hydrochloric acid partly decomposes it with separation of ammonia, and partly converts it into a third isomeride ; t,reatment with hot alkali causes it to evolve ammonia.The substance B melts at 105O (at 107'after crystallisation from benzene), and is more soluble in water, but less soluble in benzene and in dilute hydrochloric acid than A is ; strong hydrochloric acid dissolves it, but without decomposition, for alkalis precipitate it from the solution in the form of tbe third iso- meride ; it reduces silver nitrate. The third isomeride crystellises in needles, melts at 200-201°, and is freely soluble in hot water, but only sparingly so in benzene ; it is the most stable of the three iso- merides, and yields a sparingly soluble plutinochloride, The reaction of A with nitrous acid yields a compound, C7&N,, crystallising in rhombic prisms, which melt and decomporJe at 213O. Diazobenzene sulphate reacts with B to form cyanoacetonepheayl- hydrazone.The constitution of these isomerides remains unknown.

A condensation product, CI5Hl3N3, is obtained on adding concen- trated hydrochloric acid to benzaldehyde ( 1 i mols.) and cIia..eto- nitrile (I mol.) dissolved in gla,cial acetic acid; it crystallises in white needles, melts at 205-206', and dissolves sparingly in ether and benzene, but not in water. If the action takes place in alcoholic solution in presence of sodium ethoxide, the product melts at 201-202', but is converted into the above compound by dilute snlphuric acid. Dipropionitrile (Abstr., 1889, 114, 8411) is a far less active com- pound than diacetonitrile, and enters into reaction with diazobenzelle chloride alone of the reagents mentioned above.The compound, C12H14N4, thus formed, crystallises i n microscopic, yellow prisms, and melts at 151'. Acetopropion yldinitrile (imidoacet y lpropionitrile), NH:CMe*CHMe*CN, prcpared from a mixture of methylic and ethylic cyanide in the manner adopted for diacetonitrile, forms crystals, which melt a t 113'. Its benzoyl derivative, CbHTBzN2, crystallises in white needles, and melts a t 98-100'. Benzacetod ini t ril e, NH :CP h*C H2* C N, combines wi t'h carba nil to form an additice compound, which crystallises in needles, melts at about 19;Lo, and is not soluble either i n acids or in alkalis. By satu- rating an alcoholic solution of benzacetodinitrile with hydro yen chloride, a compound, CleB12N20, analogous to that formed by heating diacetonit,rile with water, is obtained ; this ciystallises in long, white needles, aird melts at 144'.Cp avacetoph enonephenylhydrazone, C0Ph.C (N2HPh) *CN, i B the product of the reaction between benzacetodinitrile and diazobenzene chloride ; it crystallises in yellow needles, melts at 135', dissolves in ammonia, and yields a silver derivative. With benzaldehyde, benzacetodinitrile yields benzylidenelenzncelo- PhFN>CHPh, which crystallises in rhombic lamina, and dinitrile, melts at about 260' ; it is insoluble in water, and only sparingly soluble in ether and in alcohol. By the action of nitrous acid on benzacetodinitrile, a nitrite, crystal- lising in needles and melting a t 15l0, is formed ; this loses nitrous acid when treated with hydrochloric acid, yielding isonitrosocyanaceto- phenone, COPh*C(NOH)*CN, which forms st.ellate groups of crystals, and melts a t 122' ; its silver compound was prepared.Bt.nzopropiodinitrile (imidobenzoylethyl cyanide (Abstr., 1889, 577), yields the conq~ound, CIoHloN20, when treated with hydroxylamiue ; the new subbtance crystallises in needles, and melts at 92'. Paratohacetodinitrile, NH:C ( C6H4Me)*CH2*CN, from met hyiic cyanide aiid parlttolylic cFanide, crystallises in broad prisms, melts a t 1(~8", and dissolves sparingly in hot water, but freely i n ether and benzene. When heated with dilute hydrochloric acid, it is converted into cyanoniethyl paratolyl ketone, C6H4Me*CO*CH,*CN, which crystal- lises in slender prisms, and melts at 10".105' ; the corresponding oxime melts at 150-151'.With phenylhydrazine, paratoluaceto- CN-CHORGANIC CHEMISTRY, 585 dinitrile yields laminae, which melt at 169', and are too stable to be a phenylhydrazone. Bromoparatoluacetodinitrile melts at 16P0, and ckloropar~toluacetodinitrile a t 149'. The benzoyl derivative of para- to1 uacetodinitrile melts at 179', and the benzylidene derivative (see above) melts and decomposes at 215'. CyanomethyltolyZketone phenyl- hydrazone, from diaxobenzene chloride and paratoluacetodinitrile, melts at 152-153'. Pa.ratoZupropiodinitriZe, NHX ( CsH4Me) *CHSle.CN, from paratolylic cyanitie and ethylic cyanide, melts at 98-99" ; with hydroxylamine it yields, not the appiwpriate ketoxime (see above), but the isomeric: ;sozmzoZonimide, ClIH12N20, which crystallises in white prisms, and melts at 134O.Diphenacetonitrile, NH:C( CH,Ph)*CHPh*CN, from benzylic cyan- ide, is an oil which was identified by the fact that i t yielded the same oxime (m. p. 107') as that obtained from a-cyanophenyliiiethyl benzyl ketone, CH2Ph*CO*CHPh*CN ; this ketone is prepared by the con- densation of ethylic phenylacetate and benzylic cyanide in the presence of sodium ethoxide ; it melts at 85-86', and is converted by gaseous ammonia at 170' into diphenacetonitrile. Benzop h enacetodinitrile, NH: C P h* C HP h* CN, prepared by the action of gaseous ammonia at 170' on the corresponding ketone (see below), crystallises in laminae and melts at 146'. a-C'yanodeoxyhenzoin, COPh*CHPh*CN, prepared by the condensation of ethylic benzoate with benzylic cyanide in presence of sodium ethoxide, melts a t 87-90".A. G. B. Ethenylic Trisulphide. By P. CANDIAXI (Gazzetta, 1895, 25, i, 81-88).--Ethenylic trisulphide is conveniently prepared by the action of bromine vapour on thioacetic acid in a closed tube at ordi- narp temperatures; the action is an indirect one, the trisulphide being produced by the agency of the hydrogen bromide which is evolved, for on sealing up thioacetic acid in a tube with an arrange- ment by which waker is caused to act on phosphorus bromide, thus liberating hydrogen bromide under pressure, et henylic trisulphide is obtained. Cryoscopic determinations in benzene solutions show that the substance has the molecular formula C,H12Ss. For 9.9-11.5 per cent. benzene solutions a t 15*9', the molecular refractions are 137.34 and 77.66, and the atomic refractions of sulphur are 13.58 and 7.53 for the a-hydrogen ray, calculating by the empirical and theoretical formulae respectively.These values of the atomic refractions approxi- mate closely to those deduced from the refraction constants of ethylic snl phide. Bromine acts on an ethereal solution of thioacetic acid, yielding a dense, oily substance, which fumes in the air and slowly loses hydro- gen bromide during distillation under reduced pressure ; it seems to have the composition C6Hl,Br2SO,. w. J. P. Optically Active Halogen Derivatives. By J. ACHILLE LE BEL (Ber., 1895, 28, 1923--1924).--The author points out that Walden, in his recent paper having the above title (tbis vol , i, 450), makes no mention of a previous paper of the author's (Abstr., 1894, ii, 77), in586 ABSTRACTS OF CHEMICAL PAPERS. Acid.------ Hydrochloric. .......... Nitric ................. which the same qiiestion was discussed and a number of the same active halogen derivatives described. Thus the author also obtained the active methjlic salt of sarcolactic acid, and converted it into the acetin a.nd but'yrin, which are Izevo-rotatory, whilst Walden's chlor- hydrin and brombydrili are dextro-rotatory, the relation of these com- pounds being the sn.me as with the corresponding derivatives of secondary amylic alcohol. On the other hand, the active monochlor- hydrin of propylene glycol, CH,*CH(OH)*CH&l, behaves in a totally different manner, as when the hydroxyl is displaced by chlorine the sign of rotation remains unchanged, but changes when hydroxyl is displaced by the acetoxy-, chloracetoxy-, or butyroxy-groups.It is evident, therefore, that halogen derivatives form an exception to Guye's hypothesis. H. G. C. The Multirotation of Dextrose. By A. LEVY (Zeit. physikal. Chem., 1895, 17, 301--324).-The retrogression of the multirotation of a solution of dextrose is accelerated by the addition of small quan- tities of acids or stroiig bases, and t,he author conducted a series of experiments to determine the comparative effects, in this respect, of various compounds at various concentrations. In these determina- tions, the half shadow apparatus of Schmidt and Haensch was employed, the tube being 80 mm. long, and although this length of tube minimises the errors consequent on the use of a short tube, it has many manipulative disadvantages.The value of the velocity of retrogression was obtained from the equation C = 1 + (tz - t l ) x log {PI - - @)I where $I is the final rotation and and p2 that after times tl and t2, a form of expression which does not necessitate a, knowledge of the absolute values of tl and t2. The values so obtained with pure water are 0.00637 (T = 20*2S0) and 0.00610 (T = 20.1). Researchee are next recorded with acetic, propionic, sulphuric, nitric, hydrochloric, c hloracetic, dichloracetic, and trichloracetic acids in N/10, and frequently, also, N/30 solutions. The velocity is found to be dependent on the nature and concentration of the acid, and the intimate connection between this effect of the acid and its affinity constant is seen in the accompanying table.1. -- 100 m o o 98 -99 96 *67 71 *95 62 *41 17 -25 4 -70 1 *63 2. -- loo *o 99 -6 62 -3 65 *1 25 -3 4.9 1 -422 0 *32 3. -- 100 *O 91 -0 68'2 73 -9 23 '0 4 '3 0 -345 0 -304 100 -0 100 -0 75 -4 73'2 27 -1 4 -84 0.4 - - 1 is the effect on multirotation ; 2, electrical conductivity; 3, catalysis of methylic acetate; 4, inversion of cane sugar. Alcohol, as expected, causes a decrease of the velocity, as does also sodium chloride ; sodium sulphate, however, causes a marked increase,ORGANIC CHEMISTRY. 587 due, the author considers, to a partial decomposition, NaJ30, + OH, = NaHS04 + NaOH, this view being further supported by the great accelerating influence of sodium salts of feeble acids, such as sodium acetate.Strong bases cause so rapid a decrease of the rota- tion that they are practically unmeasurable ; ammonia, however, was measured, and found to cause an acceleration, but not as great as that due to strong acids. Combination of Iodine with Potato Starch. By GASTOX ROUVIER (Coinpt. ?*end., 2895, 120, 1179-1180).-The maximum quantity of iodine with which potato starch will combine is 18.6 per cent., even when the iodine is present in very large excess. In the case of wheat and rice starch, the maximum is 19.6 per cent. I n presence of water, the potato starch combines with only 13.5 per cent. of theiodine, the corresponding number in the case of wheat and rice being about 8.9. When the quantity of iodine added to a given weight of starch is gradually increased, the proportion entering into com- bination also gradually increases up to the maximum, but the varia- tions are less rapid than with wheat starch and rice starch (Abstr., 1894, i, 63 and 353).It would seem that whilst starches of the same class, such aswheat starch and rice starch, behave similarly in contact with iodine, starclies derived from plants belonging to different families behave very differently. C. H. B. Oxidation of Complex Carbohydrates. By GUILLAME DE CHAL- MOT (Amer. Chern. J., 1895,17, 535--539).--The action of soda and bromine on certain carbohydrates was tried. From starch, a product is formed which reduces Fehling’s solution in the cold ; cellulose yields apparently an oxycellulose which reduces Fehling’s solution at 100’ ; the products obtained from saccharose arid from a-methyl-d-glucoside gave respectively glucosazone and a substance which was the osazone either of a-methyl-d-glucoside or of d-glucose.L. M. J. C. F. B. Aliphatic Nitramines. By H. VAN ERP (Rec. Trav. Ohim., 1895, 14, 1--55).-A study of the butylnitramines and normal hexylnitm- mines. The starting point in each cme Tias the corresponding monalkylamine, which was converted into the methylic or ethylic alkylcarbamate, and the latter nitrated ; the alkylic nitrocarbamate was then decomposed with ammonia, and the ammonium derivative of the nitramine thus formed was decomposed by dilute sulphuric acid. Normal butylamine was prepared by reducing butyronitrile with sodium in alcoholic solution, the nitrile being obtained by the zsucces- sive distillation of butyric acid with ammonium thiocyanate, and of the resulting product with phosphoric anhydride.The tertiary butylaruine and the hexylamine were made respectively from tri- methylacetnmide and normal heptoatnide by the action of bromine and alkali, the trimethylacetic acid being obtained by oxidising pina- coline with chromic acid. Normal hexy lamine may be characterised by means of dinitrohezylaniZine, C,H3(N02)2*NH*CsH,3, from 1 : 2 : 4- bromodinitrobenzene, and by the corresponding trinitro-compozrud588 ABSTRACTS OF CHEMICAL PAPERS.

The former compound crpstallises in long, slender, yellow needles, and melts at 38.2-39.2', whilst the latter forms large, yellow, doubly-refracting plates belorigicg to the asym- metric syst,em, and melts at 70-70.5"; a = 9i' 56'; p = 124' 10'; A bye-product obtained in the preparation of the tertiary butyln- = 82' 54'.mine was probably symmetrical ditertial.ybutylcarbarrLide, This is a micro-crystalline powder insoluble in water, but soluble in alcohol and ether ; i t sublimes at 250' without melting. The carbarnates were obtained by adding methylic or etbylic chlorocarbamate to a mixture of the respective amines with aqueous potash, and extracting the product with ether. They are colourless, viscid liquids, hasviug for the most part faint, ethereal odours. The yields were good. Netliylic butylcarbamate, NHBu-COOMe, melts a t -18.5' to -17*5', and boils at 92' (15 mm.) ; sp. gr. = 0.974 at 1.5' ; the ethylic salt melts at -22 5' to -21.5', and boils at 100' (15 mm.) ; sp.gr. == 0.951 at 15'. Methylic secondary butylcarbamate, CHMeEtNH*COOMe, boils at 83" (16 mm.) ; sp. gr. = 0.972 at 15'; the ethylic salt melts at -14' to -13' and boils at 89%' (15 mm.); sp. gr. = 0,9495 at 15'. Methylic isobutylcarbamate, CH,PrS*NH*COOMe, melts at -23 5' to -21", and boils at 89O (18 mm.); sp. gr. = 0.9695 at 15'; the ethylic salt boila a t 96" (17 mm.), and does not solidify at -65'; sp. gr. = 0-9465 at 15'. Methylic tertiary butylcarbamate, CMe3*NH*COOMe, melts a t 26.7-27*2', and boils a t 65.3' (17 mm.) ; sp. gr. = 0.966 at 15"; the ethylic salt melts at 20.5-22', and boils at 72' (16 mm.) ; sp. gr. = 0.943 at 15'; the odour of both these salts resembles that of menthol.Etlzylic hexylcarbamate, C,H,,*NH*COOEt, boils at 232-234" (uncorr.), and has sp. gr. = 0.915 at 15"; the melting point of a second preparation, sp. gr. = 0.9231 at 15', was -6.7'. The nitrocnrbamates are prepared by adding the carbamates to concentrated nitric acid at O", or, in some cases, at still lower tem- peratures; the product is poured on to a mixture of sodium carbo- nate crystals and ice, and the oily carbamate taken up with .ether. There is no oxidation in the case of the primary and isoprimary com- pounds, but the secondary butyl derivatives are prepared only with great difficulty, and the tertiary compound could not be prepared at all. The yields were almost theoretical. The nitrocarbarnates are nearly colourless, oily liquids of faint ethereal or aromatic odonr.They solidify a t low temperatures to crystalline or porcelain-like masses, and apparently cannot be distilled without decomposing. Methylic butylnitrocarbamate, NO,*NBu*COOMe, melts at -35.2' to -34.2'; sp. gr. = 1.149 at 15'; the ethplic salt is still liquid at -70" ; sp. gr. = 1- 1055 at 15'. Nethylic secondary hutylnitrocarba- onnte, CHMeEt*N(NO,)*COOMe, becomes viscid at - 70' ; sp. gr. = 1.1355 a t 15'; the ethylic salt remains liquid at -70'; sp. gr. = 1.094 at 15'. Methylic is0 butylnatrocarbamate, CH,PrP.N (NO,) *C 0 OMe, melts a t 2'; sp. gr. = 1.144 at 13'; the ethylic salt becomes very slightly viscid at -75'; sp. gr. = 1.101 at 15'. Ethylic hexylnitro-ORGANIC CHEMISTRY. 589 carbamnte, C6H,3eN(N02)*COOEtr, solidifies at - 60°, and melts at -445' to -40'; sp.gr. = 1.062 at 15'. The nitramines are prepared by saturating the dry, ethereal solu- tions of the methylic or ethylic nitrocarbamates with dry ammonia, the resulting crystalline ammonium salt of the nitramine being de. composed with dilute sulphuric acid, and the amine separated partIg mechanically and partly by extraction with ether ; the yield was in most cases almost theoretical. The nitramines are colourless, some- what viscid liquids, having little odour; they are only sparingly soluble in water, but easily i n the usual organic solvents ; the aqueous solutions are alkaline to litmus. They readily dissolve in alkalis, forming salts from which various metallic and alkylic salts can be prepared. It is noteworthy that both butyl- and isobutyl-nitra- mines form two methylic derivatives, to which apparently the same structure must be assigned.Butylnitramine, NHBu*N02, melts at, -0.5' to +0.5' ; sp. gr. = 1.0665 at 15' ; the ammonium derivative crystallises in small, white, glistening scales, and superficially disso- ciates in air into its proximate constituents ; the potassium, barium, and silver derivatives are crystalline. The two mefhyl derivatives are prepared respectively from the potassium compound by the action of methylic iodide and methylic alcohol, and from the silver derivative by means of methylic iodide in ethereal solution. a-Methy Zbuty 2- nitramine, NMeBu*NO2, bas an odour of menthol ; i t boils at 107.7' (15 mm.), and is still liquid at - 30" ; sp. gr. = 1.031 at 15' ; P-,Wethyl- butyznitramine, NMeBu*N02 (?), has, on the other hand, a very pnn- gent odour ; i t boils at 75-88'; sp.gr. = 0.9865 at 15'. Secondary butytnitramin,e, CHMeEt-N02, melts at -34.5' to -33'; sp. gr. = 1.066 at 15' ; the ainmoniuin, barium, and silver derivatives are crys- tallinc, but neither the potussium nor the sodium derivative could be crystallised : the former is very hygroscopic. Lobutylnitramine, CH2P#*NH*NO2, is a white, crystalline substance, and melts at 32.2'; sp. gr. = approximately 1.142; the ammonium and silver derivatives are crystalline ; the pot assiunr derivative crystallises with 1 mol. H20, which i t loses at 125', and the anhydrous compound decomposes at 245' wihhout melting. The two nzethylic derivatives were prepared in the same way as those of the uormal butyl deriva- tives ; a-methylisobutylnitramine forms small, colourless crystals, and resembles the corresponding normal compound in odour; it melts at 22.4', and boils at 104-104.2' (17 mm.). p-MetiiyZisobutylnitrt~mine also resembles the corresponding normal compound in odour ; it boils at 63-66' (17 mm.), and is still liquid at -20".Hexylnitrunzine, C~HI~*NH*N 02, melts at 5.5-6-5' to a colourless liquid, of sp. gr. = 1.014 at 13'; the ammonium derivative forms colourless, greasy scales, and is very soluble in water ; the potassium derivative is crystalline, and commences to melt at 230°, but the melting is not complete at the temperature, 280', at which decom- position sets in. The specific gravities of the alkyl nitramines and nitrocarba- mates, as of other homologous compounds, diminish as the series is ascended; the relations between the melting points of the various isomeric butyl compounds are normal.The silver and cobalt derivatives are crystalline.590 ABSTRACTS OF CHEMICAL PAPERS. Hexylnitramine is completely decomposed by dilute sulphuric acid into two hexylic alcohols, a hexylic ether, a hexylene, and nitrous oxide. The kexylene, probably CHBu:CH,, is a colourless, mobile, and extremely volatile liquid, resembling light petroleum in odour ; it boils at 67.5-68.5' and has a sp. gr. of 0.683 at 15'. The corres- ponding dibromohexane, probably CHBuBr*CH2Br, is a colourless liquid, of agreeable ethereal odour, and decomposes when distilled, to some extent even under diminished pressure.I t boils at 90-93O (18 mm.) ; sp. gr. = 1.604 at 15'. One of the hexylic alcohols was identified as the normal primary alcohol; the other, which boiled at 140--142O, and bad a sp. gr. of 0.819 at 15', yielded a blue pseudocitrole, and wits therefore a secondary alcohol, probably methyl- butglcarbinol. The dihexytic ether boiled at 218-221'. The decomposition, as far as regards the formation of the primary alcohol, resembles that of the nitrites and nitroso-derivatives of the amines, but the mechanism of the formation of the secondary alcohol and the olefine has yet to be explained, for neither of these products can be formed from the other under the conditions under which they are formed from the nitramine. I t is possible that the nitramine is aimply resolved into the olefine and free nitramide, NH2*N02, and that part of the nitrous oxide is due to the decomposition of the latter.The monalkyliiitramiues and those dialkylnitmrnines, such as di- ethyl- and dipropyl-nitramine, which do not contain a inethyl group, aye stable towards a1 kalis, but the methylalkylnitramines are decom- posed by aqueous potash in a complex manner. Dimethylnitramine, for example, yields methylamine, nitrous acid, and formic acid, together with a small amount of dimethylamine, and probably some meth ylic alcohol. Methylbutylnitramine yields, but with greater difficuity, butylnmine and formic and nitrous acids. Hexamethylenetetramine Salts. By MARcm DELEPINE (BUZZ. SOC. Chim., 1895, [3], 13, 352-355).-Hexarnethylenetetramine crystallises in forms which belong either to the cubic system or to a closely approximating rhombohedra1 system ; the crystals, which are formed equally well from aqueous and alcoholic solutions, are extremely clear, and highly refractive.The arnine is soluble in all the usual solvents with the exception of ether; tbe percentage solubilities at 12' being 81.30 for water, 3.22 for alcohol, and 8.09 for chloroform. The hydrate, CsH12N4 + 6Hz0, separates in very large striated prisms when the aqueous solution is exposed to temperatures about 0' ; it melts below 15O, but as the quantity of water liberated is insufficient fo retain the whole of the amine in solution, a portion of the latter is precipitated in the anhydrous state. The hydrobromide crystallises in brilliant rhombehedra, a : p : : 6 = 1 : 1 : 1 : 1.034.The aulphate, C,HI2N4,H2SO~ + H20, is it white, crystalline powder, which melts at 108', boils aud probably decomposes at 130-140°, and solidifies and melts again at about 188'; it is stable at 100'. The phosphate, 5CaHl2N4,6H3PO4 + 10H20, forms white colourless, nacreous crystals, and melts at about 1 8 8 O , at the same time decom- posing. The tast.e of all three of these salts is extremely acid, and it JN. W.ORGANIC CHEMISTRY. 591 is noteworthy that their melting points are all in the neighbourhood of the temperature at which the amine itself decomposes. JN. W. Hexamethylenetetramine Bismuthiodides. By MARCEL DErAi- PINE (Bull. SOC. Cltirn., 1895, [ 3],13,351-352).-A fourth bismuthiodide, (CsH,,N4*H~),,(Bi14H), + 4H,O, is obtained by adding the amine to an excess of the product of the action of acid bismuth sulphate on potassium iodide ; it is a dense, orange-yellow microcrystalline precipitate, which, after remaining for several months in contact with the original solution, is transformed into needles of a somewhat redder shade.When heated a t loo', it, loses water and becomes still darker in colour, bnt the dehydrated substance gradually reabsorba the water on exposure to moist air. Action of Methylic Iodide on Dimethylasparagine. By W. KORNER and AKGKLO MENOZZI (Gazzetta, 1895, 25, i, 97--100).-The behaviour towards methylic iodide of the dimethylasparagine pre- viously prepared by the authors (Abstr., 1890, 869) is completely analogous to that of asparagine itself; when heated with methylic alcoholic potash and methylic iodide, it yields tetramethylammonium iodide and methylfumaramic acid, NHMe*CO*CH:CH*COOH.The new acid crystallises from water in anhydrous prisms melting at 208', and yields methylamine and fumaric acid on boiling with aqueous potash ; its potassium salt separates from water in lustrous, anorthic prisms ; a : b : c = 0.692 : 1 : 0.441. = 73' 19'. The sodium salt crystallises in transparent lamina, the silver salt is an insoluble, amorphous powder, and the methylic salt crystal- lises in transparent needles melting a t 138'. The acid described by Giustiniani as methylfumaramic acid (Abstr., 1892, 821), if pure, cannot have the same constitution as the above, owing to the differences between the melting points and habits.W. J. P. JN. W. a! = 85' 32', ,3 = 94' 56', Glutarimide. By R. SELDNER (Arner. Chem. J., 1895,17, 532- 535).-Glutarimide, CH2<CH:.Co>NH, CH *CO is formed by heating together in sealed tubes at 200-210°, glutaric acid (1 mol.) and acetonitrile (2 mols.), or glutaronitrile (1 mol.) and acetic acid (2 mols.), or glutaric acid (1 1x101.) and glutaronitrile (1 mol.), a drop or two of acetic anhydride being added to cach tube. The last method gives the best yields, in the two others, the glutarimide is mixed with acetic acid and acetonitrile. C. F. B. Addition of Bromine to Tetrolic acid. By ADOLF P~NNER (Bey., 1895, 28, 1877--1887).-The aathor has previously stated (Abstr., 1881, 793) that tetrolic acid forms a, dibromide, which melts at 95-97'.Michael and Pendleton (Abstr., 1888, 1176) have since prepared the same dibromocrot.onic acid, and give 94O as the melting point, whilst Fittig and Clutterbuck, by the addition of bromine t o tetrolic acid, obtained a dibromocrotonic acid which melted at 120°, but were unable to prepare the acid melting at 94'.592 ABSTRAOTS OF OEEMIOAL PAPERE. The author has re-examined his acid and finds that it melts at 94O, and uot a t 95-97' as originally stated; he also finds that his acid is entirely different in crystallographic properties from the acid described by Bittig and Clutterbnck. It is now shown that the product obtained by the action 04 bromine on tetrolic acid depends not only on whether the operation is carried out in sunlight or in the dark, but also on the solverit used.Bromine (2 atoms) acts on a cooled aqueous solution of tetrolic acid, forming the dibromocrotonic acid which melts at NOo, together with a small quantity of acraldehyde ; if, however, the bromine is added in the dark, the dibromocrotonic acid, of melting point 94O, is formed. Bromine acts in much the same way on tetrolic acid in a chloroform solution cooled to 0'. Even when excess of bromine is employed, one of' the dibromocrotonic acids is the product formed, but if carbon tetra- chloride is used as the solvent, and the bromination is carried on in directl sunlight, hydrogen bromide is evolved, and the main product is tribromocrotonic acid (m. p. 13l0), compare Fittig (AnrutZen, 1892, 268, 107). When the bromine is added to the carbon tetrachloride solution in the dark, no hydrogen bromide is evolved, and the product is a mixture of the two isomeric dibrornocrotonic acids.The author regards these two acids as stereoisomeric. Me*g*Br Me*g*Br COOH.C*Br BPC-COOH M. p. 94Jo. M. p. 1200. The acid with the lower melting point is the less stable. Its salts, when heated with water, lose carbonic anhydride and hydrogen hro- mide, and then form acrddehyde. When hydrogen bromide is passed into a concentrated benzene solution of the acid of lower melting point, it is converted into the isomeric acid of higher melting point. Tetrabromocrotonic acid is obtained when either of the dibrom- acids is dissolved in carbon tetrachloride and treated with bromine in direct sunlight. It crystallises in large, glistening prisms, melts at 1 4 6 O , and is readily soluble in water or benzene, but only sparingly in carbon tetrachloride, and still more sparingly in light petroleum. The tetrabrom-acid, and also the two dibrom-acidg, when treated with sodium amalgam, yield tetrolic acid.If the tetrbrom-acid is neutm- lised with dilute ammonia, and silver nitrate is added to the solution, decomposition takes place, silver bromide is thrown down, and muco- bromic acid, COOH*CBr:CBr*CHO, remains in solution. J. J. S. Mixed Anhydrides. By L. ROUSSET (Bull. SOC. Chim., 1895, [33,13,330-334).-The mixed anhydrides of the type R*CO*O*CO*R' do not appear to exist, as their boiling points are indefinite, and they are readily resolved, by fractional distillation, into mixta res, in mole- cular proportion, of the corresponding simple anhydrides.Thus the product o€ the action of acetic chloride on sodium butyrste is a mixture of acetic and butyric anhydrides; Autenrieth's aceto- valeric anhydride, from sodium acetate and valeric chloride, is a mixture of acetic and Taleric anhydrides, and the product of theORGANIC CHEMISTRY. 593 action of benzoic chloride on sodium acetate is a mixture of acetic and benzoic anhydrides. The insBability of the mixed anhydrides affords a convenient meaus of preparing anhydrides from acid chlorides. The latter are simply heated with sodium acetate, and the mixtures of anhydrides thus obtaizled is Reparated by fractional distillation. By JULIUS W. BR~RL (Ber., 1895, 28, 1913-1914).--8 claim of priority. JN. W. Etherification and Hydrolysis.Ozobenzene. By ADOLPHE RENARD (Compt. rend., 1895, 120, 1177--1179).-1n order to obtain ozobenzene (this Journal, 1873, 610), the benzene must be carefully puritied, and the current of ozone must be well dried. When the benzene contains thiophen, only the dark-coloured, non-explosive substance, described by Leeds (Ber., 14, 975), is formed Oxobenzene, when freed from excess of benzene by means of a current of dry air, is a white, amorphous substance, which explodes violently on the slightest friction and detonates if heated rapidly to SOo, but decomposes without exploding if very slowly heated. It also detonates i n contact with concentrated sulphuric acid, ammonia, or aqueous potash. It remains unchanged in dry air, but decomposes in contact with moist air. In contact with water, it decomposes slowly, with evolution of carbonic anhydride arid formation of acetic and formic acids.By weigbing the carbonic anhydride evolved, and burning i n the usual way the other product,s of the actioii of water, i t is found th8t ozobenzene has the composition CsH606. Ozobenzene is insoluble in most organic solvents, but dissolves in acetic acid. C. H. B. Action of Acid Chlorides on a-Hexachlorophenol in Presence of Aluminium Chloride. By ETIENNE BARRAL (Bull. SOC. C h h . , 1895, L33, 13, 340--345).-When aluniinium chloride is added to a cooled carbon bisulp hide solution containing a- hexachlorophenol and an acid chloride, there is a slight elevation of temperature, bnt no evolution of hydrogen chloride, and cryst.als of an additive metallic compound can be separated from the product, (see following abstract) ; at a higher temperature, however (35-40°), a violent action takes place, h j drogen chloride is evolved, and a nearly quantitative yield of crystals of the acidyl derivative of pentachlorophenol is obtaincd.The cryst,alline product, after being drained, is digested with cold water to decompose the sulphur chloride formed in the action, and the dry substance is recrystallised from benzene or light petroleum. Pentarhlorophenylic acetate, C&15.0Ac, crystallises i n long, slender, monoclinic prisrus, and melts at 149*5-15(~*5', not at 148-149' as stated by Weber and Wolff; it remains practically unaffected by boiling with concentrated aqueous potash, but is completely hydro- lysed by alcoholic potash at 120'.The propionate forms long, soft, white, silky needles, and melts at 78.5". It is ,.asily hydrolysed by alkalis. The butyrate separates from light petrdeurn as a felted mass of fine, white, soft needles ; i t softens at 49O and melts a t 59-6;1.5O, but the product obtained was not quite pure, as the compound is594 ABSTRACTS OF OHEMICAL PAPERS. hydrolysed, even by moist air, into its proximate constituents. The benzoate crystallises in colourless, highly refractive, monoclinic prisms, sp. gr. = 1.711 at 18", and melts at 159-160O. It is stable towards strong, boiling, aqueous potash, but is hydrolysed by alcoholic potash at 120". It is probable that the sulphui* chloride and the carbon sulpho- chloride formed in the preparation result from the action of nascent chlorine on the carbon bisulphide, this chlorine being produced, together with the compound CsCl6*O*Al2Cl5, by the decomposition of the original additive compound.JN. W. Action of Aluminium Chloride on a-Hexachlorophenol. By ETIENNE BARRAL (BUZZ. Soc. Chim. 1895, [3], 13, 345--348).-Wheri a-hexachlorophenol is heated with aluminium cliloride (+ mol.) in sealed tubes atl 160--165O, the chief products are pen tachlorophenol and chloranil. With more of the chloride (4 mol.), and at 170-175', much carbonyl chloride is formed, and the principal product is hexachlorobenzene, whilst with the same proportion of the chloride, and in presence of carbon bisulphide, a reaction occurs similar to that described in the preceding abstract, pentachlorophenol, sulphur chloride, and carbon snlphochloride being formed ; a t a higher tem- perature, however, a small quantity of pentachlorophenylic carbonate, CO(O*C,Cl,),, is produced. This forms very small, colourless, nacreous crystals, which begin to sublime at about 250' and melt a t 265-268'; it can be volatilised without decomposing. Preparation of Orthodibromaniline.By W. KORNER (Gnzaetta, 1895, 25, i, 95-97).-0rthodibromttrliline [NH, : 13r2 = 1 : 3 : 41 is readily prepared by acetylating metabromaniline with acetic anhydride and brominating the resulting metlcbromacetanilide in acetic acid soluteion ; it melts at 80*&-80.5', and gives crystalline salts. The monacetyl derivative, CaH,Br,*NHAc, crystallises in thin prisms meiting at 128", and the diacetyl derivative, CsH3 Br2*NAc2, fornis lustrous scales, melting and decomposing at 208'.This dibromaniline is violently acted on when warmed with alcoholic ethglic nitrite, nitrogen being evolved and ortbodibromobenzene being produced. W. J. P. Conversion of an Aniline Salt into an Anilic acid. By LOUIS SIMON (Compt. rend., 1895, 120, 1174-1177).-Pyruvic acid and aniline do not form aniline pyruvtlte, but only anillpyruvic acid, which seems to be a consequence of the presence of the ketonic function. On the other hand, phenylglyoxylic acid yields exclusively the ordi- nary salt. It would seem, however, that this difference is more apparent than real, for, although aniline phenylglyoxylate whet] heated loses carbonic anhydride and water and is converted into benzylideneaniline, CHPh:NYh, when dissolved in cold methylic alcohol, or when boiled with chloroform or benzene, it is completely converted into anilphen~lglyoxylic aczd, NP h:CPh*COOH, a white, crjsta2lisable compound, melting and decomposing at 151' with formation of the compound CBPh:NPh.Anilphenylglyoxylic acid JN. W.ORGANIC CHEMISTRY. 595 is insoluble in boiling benzene or chloroform, and only slightly soluble in ether or cold acetic acid. When boiled with water, it is completely reconverted into aniline phenylglyoxylate. It also dis- solves in acids and alkalis. Aniline phenylglyoxylate yields an abundant precipitate with phenylhydrazine, but anilphenylglyoxylic acid does not, and this is a further proof that the ketonic function existing in the one is non-existent i n the other.Ammonia and the toluidines yield similar results. C. H. B. Benzenesulpho-orthotoluidide and its Derivatives. By CH. RABAUT (C'ompt. rend., 1895, 120, 1123-1126).-BenzenesuZpho-ortho- toluidide, C6H5*SO2*NH*CsB4Me, is obtained by heating benzenesul- phonic chloride (1 mol.) with orthotoluidine (2 mols.), in presence of benzene or strong alcohol. It separates from alcohol in white crystals, which melt at 122-1523', and boil without decomposing ad about 290-295' under a presaure of 50 to 60 mm. It is insoluble in water, but dissolves in alkalis and organic aolvents. When boiled with nitric acid of sp. gr. 1.10, it yields a yellow dinitro-derivative, SOzPh*NH*CsH,Me(N02)2, which melts at 167-168'. Under similar conditions acetylorthotoluidine is completely decomposed into acetic acid and toluidine,.The dinitro-derivative, when heated in sealed tubes at 140' with concentrated hydrochloric acid, yields a dinitrotoluidine, [Me : NH, : NO2 : NO, = 1 : 2 : 3 : 51, which melts at 208-209", and was described by Stadel (Abstr., 1881, 724). When treated by Prud'homme and Rabaut's method (Abstr., 18'32,705), i t yields the chloride C6H2hle(N0,)2Cl [Me : C1: NOz : NO, = 1 : 2 : 3 : 51, which forms yellow crystals melting at 45-46O. It follows that the original dinitro-derivative has the constitution [Me : NOz : NO, : NH*S02 = I : 3 : 5 : 61, the two benzene nuclei being linked by the group S02*NH. It has strongly marked acid properties, dissolves in alkalis, arid decomposes barium carbonate at loo', forming a barium salt which separates in yellow crystals ; theso lose 1 mol.H20 at 140°, and only decompose at about 213'. Hydro- chloric acid precipitates the dinitro-derivative, which can thus be purified. Reduction with tin and hydrochloric acid yields the diamiue in white needles, which melt a t 217' and turn red when exposed to air. It forms salts very soluble in water, and is readily diazo t ised. The general stability of benzenesulpho-orthotoluidide, notwith- standing its amide character, is especially noteworthy. C. H. B. Reduction by means of Phenylhydrazine. By R. WALTHER ( J . pr. Chem., 1895, [2], 141--144).--The author draws attention to the application of phenylhydrazine as a reducing agent in organic chemistry ; such reductions as that of azobenzene to hydrazobenzene, and that of nitro-compounds to the corresponding amido-derivatives.being easily effected by its means.

When treated with hydrochloric acid, it is decomposed into benz- aldehyde and iso7rydroxydi23hen!ltethyEami~e ; this base, which melts at 1 2 8 O , stands in the same relation to the diphenylhydroxyethylamine (m.p. 161") of Goldschmidt and Polonowska (Abstr., 1887, 492) as isohydrobenzoin does to hydrobenzoyn. If distilled with zinc dust, i t yields stilbene ; when oxidised, it gives benzile, and when diazotised and converted into the corresponding glycol, it yields isohydrobenzoin ; if heated to about ?30°, it decomposes into benzaldehyde and benzyl- amine. The original condensation product can be regenerated by heat in g iNod i phen y 1 h y d rox y e thy lam in e with benzald ehy de in alcoholic solution. The author regards his base and isohydrobenzoin as the true analogues of racemic acid, on account of the hemimorphic cha- ract er of their crystals ; whereas hydroxydiphenylethylamine and hydrobenzoin are the analogues of rnesotartaric acid.Heterocyclic Bases from Hydroxydiphenyle thylamine.

SCHAFFER.-The hydrochloride of para- iLitrosonniEine, c6H6Nz0,HC1, separates from alcohol in dark brown crystals ; the sulphate crystallises in yellowish- white prisms. The oxalate forms small, greenish crystals, and the picrate separates as a brown mass of crystals on adding ether to the alcoholic solution. The dibenzoyl derivative crystallises in dark brown needles or leaflets, and melts at 142'; in preparing it, it is necessary to dissolve the nitrosoaniline in a dilute solution of sodium hydroxide and agitate the cold liquid with excess of benzoic chloride ; otherwise, if strong soda is used and the mixture is allowed to get warm, benzoylnitrosophenol is formed.Orthoh ydroz y benz y ZideneparanitrosoaniEine is prepared by heating the base with salicylaldehgde for two hours at 100'; it softens at 235', and melts at 245'. Paranitraniline is formed when paranitrosoaniline is oxidised with potassium permanganate, whilst reducing agents give rise to paraphenylenediamine. By OTTC FISCHER and H.

The rnercurocltloride melts and decomposes at 142'. The nitrosamine of paranitrosoethylaniline is very stable in pre- sence of reducing agents.With acetic acid and zinc-dust, a colour- less oil is obtained, which gives Iiebermanli's reaction; on adding sodium amalgam to tho cold alcoholic solution of the nitrosamine, the liquid becomes reddish-brown, and a yellow precipitate is formed, which, when recrystallised from alcohol, melts at 171'. This corn- pound has the formula Cl6HlsN6o3, and gives Liebermann's reaction ; ou reduction, it yields ethylpaTaphenylenediamine. a-Nitroso-a-methy lnaphtk?llamine, c,0H6<<N NHMe > 0, is prepared by dissolving a-methylnaphthylamine in dilute sulphuric acid, adding sodium nitrite, and extracting with ether; the nitrosamine, which is left as a viscid oil on evaporation of the ether, is converted into the hydrochloride of nitroso me thylnap h thylamine by treatment with alcoholic hydrochloric acid ; this salt crystallises in slender, pale peen needles ; the picrate crystallises in greenish-yellow needles, and melts and decomposes a t 157'.Nitrosomethylnaphthylamine gives the indazine reaction, a blue colouring matter being produced on treating the alcoholic solution of the hydrochloride with diphenyl- metaphenylenedianiine ; this product, symmetrical anilido-n-methyl- ?-oshdzche, NMe:Cl~,~Nph>C6H,.NHPh, N- forms magnificent, golden-green crystals, and melts and decomposes at 225'.

The ncetyl derivative of trimethylmetaphenylenediamine is ob- tained by heating a solution of acetyldimethylmetaphenylenediamine in xylene with sodium, and, when the metal is dissolved, heating the liquid with methylic iodide; it separates from alcohol in large crystals, and melts at 68'. The base boils at 270°, and whenits solu- tion, in 10 per cent. sulphuric acid, cooled with ice, is treated with sodium nitrite in dilute aqueous solution, the liquid becomes deep red, and the dinitrosamine of dimethylmetaphenylenedismine is pre- cipitated ; this crystallises from alcohol in lustrous, brown leaflets, and melts at 109-110'.The quantity of this substance amounts to 5 per cent. of the trimethyl derivative employed, and on extracting the liquor from which i t separates with boiling ether, the nitros- amine of trimethylmetaphenylenediamine is obtained ; the hydro- chloride crystallises in colourless leaflets, and on treating it with boiling methylic or ethylic alcohol, a deep red liquid is obtained, and the monhydrochloride of paranitrosotrz'methylmetaphenylenediamine separat-es in dark red crystals with green lustre. The dihydrochloride crystallises in dark red needles. The base itself, paranitrosodimethyl- metap?~~yl~tLedia?~ine, NMea*C6H&N > 0, crystallises from benzene in long, steel-blue prisms, which appear red by transmitted light, and contain the solvent; it melts at 143".On adding aqueous sodium nitrite to a solution of the base in dilute sulphuric acid, a, nitro-derivative of trimei;hylmetaphenylenediamine nitrosamine is formed, crystallising from ether i n yellow needles, and melting at 15 7'.

Symmetrical dimethy lmetaphenylenediamine is obtained by heating the formyl derivative of monomethylphenylenediamine with sodinni methoxide and methylic iodide, and hydrolysing the product with dilute sulphuric acid.It is a colourless oil which, however, rapidly becomes brown ; it boils at 165--170" under a pressure of 10 mm., and art 275-280' under ;t pressure of 739 mm. The dinitrosamine (m. p. 109-110') is identical with the product of the action of nitrous acid on trimethylmetaphenylenediamine ; when it is dissolved in ether, and treated with cold, alcoholic hydrogen chloride, symme- trical paranitrosodirnethylmetaphenylenediamine is obtained in the form of the hydrochloride.

By HEINRICH SALKOWSKI (Ber., 1895, 28, 1917--1923).-When an attempt, is made to cyystalliee the hydrochloride of paramidophenylacetic acid from boiling alcohol, it is converted into the kydrochloyide of its ethylic .salt, NH,*CsHk* CH,*COOE t,HCl, which separates in plates, axid, on treatment with cold soda solutioo, yields ethylic parawtidoplaenykacetate, melting at 49.5'.The forma- tion of the ethylic salt does not take place at the ordinary tempera- ture, but a similar action occurs on boiling tlie hydrochloride of the acid with methylic, normal propylic, or amylic alcohol, although, in the case of the first named, the action is far from complete. The hgdro- chloride of rnetamidophenylacetic acid behaves in the same manner. In order to ascertain whether this property is characteristic of aromatic amido-acids in general, the author has examined the behaviour of a niimber of these, and finds that the hydrochlorides of ortho-, meta-, and paramidobenzoic acids undergo no etherification under these conditions, but that the amidocinnamic and amidohydro- oinnamic acids all readily undergo etherification ; the results are not altered if the hydrobromide, hydriodide, or nitrate are employed in place of the hpdrochloride, but with the sulphate no ebherification takes place.It appears, therefore, that aromatic amido-acids in which the carboxyl group is not directly combined with the benzene nucleus undergo etherificatiou by the action of boiling alcohol on their salts with hydroclloric, hydrobromic, hydriodic, or nitric acid, the relative position of the amido-group t o the side chain containing the carboxyl having no influence.This conclusion is analogous in many respects to that of V. Meyer and Sudborough (Abstr., 1894, i, 463), who have shown that diortho-substituted benzoic acids do not undergo etherifi- cation when treated with methglic alcohol and hydrochloric acid, but that etherification readily takes place in diortho-substituted acids with longer side chains.

(Ber., 1895, 28, 1870-1 872) .--Sodium eugewolacetate, CH2:CH*CH2-C,H3(OMe)*O*CH2*COONa [ = 1 : 3 : 43, is Gbtained when eugenol is heated with sodium hydroxide solution and monochloracetic acid during 20 honrs.The acid crystallises i 11 colourless needles, melts at 75', and is readily soluble in hot water, alcohol, acetone, benzene, and light petmleuni, but only sparingly in cold water ; it is only slightly volatile with steam. When this acid is heated with potassium hyclroxide and amylic alcohol during 20 houi-s. it is converted into potassiibm isoeugenolacetate. Isoeugenolacetic acid forms colourless needles, and melts a.t 92-94' ; it cannot be crystal- lised from water. When the iso-acid is oxidised with potassium permanganate i n alkaline, or, better still, in neutral, solution, the chief products arc acetaldehyde and vanilli?zacetic acid, COH*C6H,(OMe)*O*CH2.COOH [= 1 : 3 : 41, which is identical with the acid described by Elkan (Abstr., 1887, 259) as vanillinosyacetic acid.When the acid is treated with phos- phorus pentachloride (2 mols.), vanillin, trichloracetic acid, and car- bonic anhydride are formed. J. J. S. Phenylazocarboxylic acid and Tribromophenylazocarboxylic acid. By OSCAR WIDMAN (Ber., 1895, 28, 1925 -1931).-E.

The author 'has reinvestigated this substance, which has the constitutiou, NO*NPh*NH*CO*NH2, and melts at 126--127O, with evolution of nitrous fumes. If kept for a long t'ime, it undergoes spontaneous decomposition into yli eylazocarbamide, N P h:N*CO-NH2, which may, however, be more readily obtained by carefully oxidising phenyl- semicsrbnzide with potassium permanganate or dichromate.It crys- iallises from water or benzene in long, red needles, melting a t 1 1 4 O ,604 ABSTRACTS OF CHEMICAL PAPERS. does not reduce Fehling's solution, but evolves nitrogen on the addi- tion of copper powder to the boiling aqueous solution; it evolves ammonia on warming in alkaline solution, and forms salts of phenyl- aeocarboxylic acid, which are yellow, but have not been obtained pure ; on the addition of acids, i t decomposes, forming benzene, car- bonic anbydride, and nitrogen, together with other products. Ethylic phenylcarbazijtate, NHPh*NH*COOEt, obtained by mixing phenylhydrazine and ethylic chloroformate in ethereal solution, crys- tallises in long plates, or flat needles ; these contain 1 mol.H20, which is evolved on heatiug at 83" ; the hydrated componnd melts a t 79-80", and the anhydrous compound at 82 -S3". The solution in con- centrated sulphuric acid is coloured deep red by ferric chloride. When oxidised by potassium permanganate, it yields ethylic phenylazo- carboxylate, NPh:N*COOEt, which is a thin, red oil, and is converted into phenylnzocarbamide on treatment with concentrated ammonia. These substances are closely allied t o the azodicarbamide deriva- tives obtained by Thiele (Abstr., 1892, 1429), the additive compounds of diazocyanides and hydrocyanic acid obtained by Gabriel (Abstr., 1880, 41), and further with the substituted diaxocyanides recently described by Hnntzsch and Schultze (this vol., i, 348) which exist in two modifications, regarded by them as stereoisomerides.Theoreti- cally, the above derivatives are also capahle of existing in two stereo- isomeric forms, and the author has endeavoured to obtain evidence OIL this point, employing symmetrical tribromophenylsemicarbazide as the starting point, as this forms more stable derivatives. Symmetrical t r i b romop hen y 1 se m icar b a d s , CsH2Br3*NH*NH*CO*NH2, is readily obtained by the action of potassium cyanate and acetic acid on symmetrical tribromophenylhydrazine, and forms very sparingly soluble needles, melting at 235-236", with evoln tion of gas. When oxidised with acetic acid and potassium permanganate, it is converted into the corresponding symmetrical tribromophenylazo- carbamide, C6H2Br3*N:N*CO*NH2, which crystallises from benzene in long, flat, red needles, and melts and evolves gas at 176" ; no definile evidence of the existence of an isomeric compound could, however, be obtained. Potassium tribromophenylcarboxylate may he obtained by the action of aqueous potash on the carbamide; it crystallises in long, yellow needles, which explode on warming, or when touched with concen- trated sulphuric acid.On adding dilute sulphuric acid to the well cooled solution, a yellowish-white precipitate separateq, probably con- sisting of the free tribromophenylazocarboxylic acid, but this decom- poses in a few seconds with evolution of gas and formation of tri- bromobenzene.During the investigation, the following acetgl derivatives of symmetrical tribromophen ylh y draz ia e were prepared. p- Acet y Et 1% byomophenylhydrazine, CsH2Br3*NH*NHAc, which forms well developed, four-sided prisms, and melts at 1 8 8 O , and ap-diacetyltribromophenyl- hy&-azine, C6H2Br3*NH-NAc2, crystallising in brittle needles melting at 144-145".

By EMIL FROMM (Bey., 189.5, 28, 1%5--1940) .-The imidodicarboxylates described by the author (Abstr., 1893, i: 575, this vol., i, 418,461), amre, with one exception, not acted on by alkyl halo'ids in alkaline solution with substitution of the alkyl radicle for the hydrogen oE the imido- group.. Trithiodibenzylic imidodicarboxylate, ho werer, is acted on under these conditions forming trithiot,ribenzybic pseudoirnidodicar- hoxylate, which crystallises in spherical aggregates of needles melting a t 92'. Two forniuh are possible for this substance, namely, C7H7N<CSSC,H7 c0sc7H', and C7Hi*CO*S*N:C ( SC7H7),, as, however, it yields no benzylnmine, but considerable quantities of ammonia when distilled with aqueous potash, its constitution must be represented by the second formula. In its formation, the trithio- dibenzylic imidodicarboxylate reacts in the tantomeric form, and it is probably owing to their incapability of reacting in this form that the other imidodicarboxylates are not affected by benzylic chloride and soda. When phenylmethylthiobiuret is heated wtth benzylic mercaptan and hydrochloric acid on the water bath, it is converted into benzyZic tm'thioallophanate, C,H7S*CS.NH*CS*NH2, which forms sulph ur- yellow needles and melts at 142-143'.The actim of ammonia on this substance was investigated in the hope that the hitherto un- known dithiobiuret would be formed ; this is, however, not the case, the products of the action being benzylic mercaptan and ammonium t hiocyanate.

It is decomposed by concentrated sulphuric acid, but dissolves without change in alkalis and concentrated bydrochloric acid ; tbe rotatory power [ a ] D = - 10.4' in 2.5 per cent. alcoholic solution. The silver salt. C11H11031SNAg, is amorphous ; the barium saZt crystallises with 2H20 ; the ethylic salt forms colourless needles melting at 104-105".

By the action of potassium cyanate on iodophen y lc y ste'ine, the zwamid o-acid, NH&DNH*CMo ( SC6H41) COOH, is formed, and cryst,allises in small needles melting at 195-196'. With acetic anhydride, iodophenylcystehe regenerates the mer- captoric acid.When heated with potash, iodophenylmercapt.nric: acid is resolved into ammonia, acetic acid, pyrnvic acid and pariodo- phenylmercnptnn. The latter crjstallises in needles, melts at 85-86', has a characteristic odour of aniseed, gives yellow precipitates with copper, lead, and silver salts, and is rapidly oxidised by the air to pariodophenylic bisulphide, CI2H8l2S2 ; t'his crystallises in plates, melts at 124O, and gives a dark-blue solution when warmed with sulphuric acid. Both compounds were identical with synthetical preparations obtained from iodo benzenesulphonic acid, proof being thus afforded that the iodine is in the para-position. Pariodophenyl- mercapturic acid is thus shown to have the formula NHAc.CMe ( SC6H41)*C0 OH. J. B. T. Synthesis of the Diphenylic Hydrocarbons : Para- and Ortho- phenyltoluenes.By GIUSEPPE ODDO and A. CURATOLO (Gazzetta, 1895, 25, i, L26--136).-A diazotised mixture of aniline and para- toluidine is slowly added to alcoholic sodium ethoxide, gas is evolved, and, after heating on the water bath in a reflux apparatus, the solu- tion is distilled in a current, of steam. The distillate is extracted with ether and the extract evaporated ; on fractionally distilling the rcpidue, paraphenyltoluene, CsH,PhMe, is obtained as a colourless liquid, which boils at 262-268', and solidifies in LZ mixture of ice and salt ; it is accompanied by small quantities of benzene, toluene, and dipheny 1. By substituting orthotoluidine for its para-isomeride in the above process, orthophenyltoluene may be prepared ; it is an oil which does not solidify in a mixture of ice and salt, boils at 261-2264', and yields orthodipheny lcarboxylic acid on oxidation with chromic acid.It readily takes up bromine, yielding a tiibromo-derivative, C,3H9Br3, which crystallises in long, white needles melting at 167-169', and is easily oxidised by chromic mixture ; by the aid of this compound, it is shown that a very small proportion of orthophenyltoluene is formed by the action of sodium on a mixture of bromobenzene and orthobromotoluene in ethereal solution.

It is precipitated from its solution in strong sulphuric acid unchanged, unless the solution has been kept, in which case benzile and hydrazine sulphate are produced. Reduction with zinc dust in glacial acetic acid converts bisbenzoylphenylazimethylene into benzyl phenyl ketone and ammonia. Bsnry lphenylmetlLyZenehyd~axiiie, CI'H,PhCPh:N-NH,, is prepared by heating benzyl phenyl ketone (5 grams) with hrdrazine hydrate (1.3 grams) and a couple of drops of alcohol in a sealed tube at 140" for five hours; i t crystallises in white needles, melts at 62O, and dissolves freely in alcohol, ether, and chloroform; it distils unchanged, and reduces ammoniacal silver nitrate and Fehling'h solution.This hy drazine is a true secondary hydrazine, undergoing condensation with aldehydes in the cold and with ketones when CHPh*NH*CHPh608 ABSTRAOTS OF OHEMICAL PAPERS. warmed. bisbenz y lphen y 1 azir.net hy lene ( b e m y lph en y 1 ket azine) CH,Ph*CPh:N*N:C Ph*CH,Ph, which crystallises in small, straw-coloured needles, melts at 164', dis- tils unchanged, and dissolves in ether and chloroform, but not in water.

When treated with iodine in alcohol, it is converted into The Induline Group.By Orri!o FisCHER and EDUARD HEW (Annalen, 1895, 286, 187-247 ; compare Abstr., 1893, i, 333, and this vol., i, 527).-The system of nomenclature already developed (loc cit.) is retained, benzeneindulines, in which the substituent radicle takes up the position R (general formula I) being referred to as meso- derivatives. The most productive source of meso-phenyliiiduline, C,,B ,sNa, is aposafranine (Abstr., 1893, i, 613). This base is characterised by its green solution in oil of vitriol, the colour of the solution in acid con- taining the monhydrate or anhydride being brownish-red ; the salts form magenta-red solutions in water. The base dissolves readily in methylal, and, on evaporation of the solvent, is deposited as a crys- talline crust, having a beautiful, dark green reflex ; when dry, it may be heated at 100' without undergoing change, but, on boiling the solution in benzene, a powder separates, forming a brown solution in concentrated sulphuric acid, and dissolving with dificulty in the dilute acid or in acetic acid, yielding reddish-violet solutions.At the same time, a small quantity of rneso-phenylinduline is formed, this being most readily obtained by heating aposafranine hydrochloride with aniline in the manner already described (Zoc. cit.). The nityate of meso-phenylinduline crystallises from alcobol in lustrous, green needles ; the platinochloride forms slender crystals having a dark green reflex, and the aurochlon'de crystallises in lustrous, green needles.The base itself, which has also been called arnidoazobenzene- induline, melts at 203-204', and not at 215' as previously stated (ibid., 33.5) ; the action of a mixture of glacial acetic and hydrochloric acids, during six hours at 160-170°, gives rise to benzeneindone hydrate, whilst treatment with alcoholic barium hydroxide for 10 hours at 140-145' converts it into benzeneindone (Abstr., 1892, 341). Phenylmesqhenyliiiduline, C2aH17Ns, has already been described as the product of the action of aniline on mesophenylinduline, and is most conveniently obtained by heating aposafranine with aniline for an hour a t 150-160' ; paratolylnzesoparatolylinduline has been prepared by a similar process, and melts at 227-228'. Phenylmesoamidophen-jlinduline (loc. cit.) is formed when azo- phenine (4.5 grams) and paraphenylenediamine hydrochloride (2 grams) are heated with aniline (10 grams) and alcohol (50 grams) for 12 hours at 140" ; this process depends on the oxidation of a mixture of paraphenylenediamine and aniline, and the same principle is pro- bably involved in an alternative method, when these bases are heated at 150' with quinonedianil.The base is primary in character, and the formy2 derivative crystallises in bluish-green leaflets, which transmit red light, and melt at 230" ; the rnonacetyl derivative softensORGANIC CHEMISTRY. 609 at 150' and melts at 160°, and yields an acetate which melts and de- composes at 183'. Unsymmetrical hydroxybenzeneindone is obtained by heating phenyl- mesoamidophenyliiiduline with alcoholic barium hydroxide for 3; hours at 180--200°, and is freed from mesohydroxyphenylinduline by treat- ment wit.h dilute hydrochloric acid, which precipitates the latter base : the crystalline substance has a bronze lustre, and the solution in concentrated sulphuric acid is brownish-red, becoming orange 011 dilution.The dilute solution in alkalis is red, and exhibits greenish fluorescence, which is also noticeable in the alcoholic solution. The hydrochloride of mesohydroxyphenylinduline, which is formed at the same time, separates from glacial acetic acid on the addition of water in lustrous, giaeen crystals ; the solution in Concentrated sulphuric acid is green, becoming brownish-red and finally red on dilution, whilst the red, alcoholic solution exhibits feeble, brown fluorescence.The benzy Zidene derivative of phenplrnesoamidophenylinduline crys- tallises from the dark red, alcoholic solution in small needles, having :t green reflex ; it melts at 261-26So, and in the finely divided stato has electrical properties and transmits red light. The orthoh ydroxy- benzy Zidene compound crystallises in dark brown leaflets transmitting reddish-yellow light. As already suggested, the mauve'ines and indazines are to be regarded as -- symmetrical indulines, having the general formula NH:C6H3<gi> C6H3*NH2. In preparing dimethylmauve'ine from nitrosodimethylaniline and diphenylmetaphenylanediamine, a buse, CzaHz7N5, is obtained; this dissolves in benzene, forming a violet solution, and, on evaporating the solvent, is deposited as a IustrouP, green, crystalline powder, which contains benzene an6 melts at 178' ; when this is heated in the vapour of boiling xylene, the benzene is removed, and the subst.ance then melts at 210-212O.The formatioii of two bases is also observed when nitrosomonomethylaniline, ni troso- mone thylnniline, or nitrosodiethylaniline is heated with diphenyl- metaphenylenediamine. Thus, phenyla~~idophen~tnzauvei'ne, is formed, together with phenylmauvehe, when nitrosodiphenylamine (28 grams) and diphenylmetaphenylenediamine (26 grams) are heated with 40 per cent. hydrochloric acid (5.5 grams) and alcohol (800 grams) on the water bath, and allowed to remain for 20 hours at the ordinary temperature; the crystals have a bronze lustre, and the Rubstance sinters at 175", and melts and decomposes at 202O.Phenylmnuveine, liquor. The solution of this base in concentrated sulphuric acid is grass green, a greenish- blue coloration being developed when phenyl- amidophenylmauveine is dissolved in concentrated snlphuric acid ; it is less readily soluble in benzene than the foregoing base, the solution being reddish-violetl, and depositing the base in crystals which610 ABSTRACTS OF CHEMICAL PAPERS, contain the solvent. 256-257". After being dried at 140', the base melts a t Symmetrical Bz-.e-anilidobenzele~~aau~i~~e (mauvindone), C6H30<&> C6H3*NH P h (Abstr., 1893, i, 464), dissolves only sparingly in benzene and toluene, but is more readily soluble in alcohol, and is deposited from a mixture of benzene and alcohol as a crystalline powder with bronze lustre ; the solution in concentrated sulphuric acid is bluish-violet, becoming red on dilution.When the base is heated with alkalis, or when phenylmauve'ine is heated with alcoholic barium hydroxide for 5-10 hours at 180°, symmetrical hydroxybenzeneindone is formed, aud this i 4 found to be identical with safranol obtained by the action of alcoholic: potash on phenosafranine, which is converted first into the sym- metrical induline, yieldirjg n?nidobenzeneindoiae, on protracted treatment with alcoholic potash. From benzene con- taiaing some alcohol, i t crystallises in magniiicent prisms, having a green lustre ; the base is somewhat soluble in water, and the solution in concentrated sulphuric acid is violet, becoming pale brown on dilution. When aposafranine is heated with alcoholic potash for 16 hours, a certain amount of benzeneindone hydrate is formed, together with a blue coloiiring matter.According to this method of preparation, safranol contains only one hydroxyl group, although Nietzki and Otto have regarded it as a dihydroxy-derivative ; moreover, the ethers contain only one ethyl group and are insoluble in alkalis. The ethyl ether crystallises from alcohol in prisms having a bronze lustre; it melts and decomposes at 265', and dissolves in concentrated sulphuric acid with a reddish- brown coloration, becoming yellow on dilution. The alcoholic solution is red, and exhibits feeble, brown fluorescsnce. The methyl ether melts at 240'. Mononitrop7Lenylro~~duline is obtained by adding potassium nitrate to a solution of phenylrosinduline in concentrated sulphuric acid and heating the liquid at 50-60° ; it crystallises in almost black leaflets witha green reflex, sinters at B50°, and melts at 270".The solution in concentrated sulphuric acid is green. Trinitrophenyl?.osdu.line is formed on adding fuming nitric acid to a solution of phenylrosinduline in glacial acetic acid ; it crystallises from nitrobenzene in red leaflets or needles. These nitro-derivatives yield rosindone and nitranilines when heated with glacial acetic acid and concentrated hydrochloric acid for some hours at 180-200'. Nononitrorosindone separates from its solution in nitrobenzene in dark red crystals, and from glacial acetic acid in bright red needles; the solution in concentrated sulphuric acid is violet.Amidorosindone crystallises from ether in lustrous, dark blue leaflets; it forms t w o series of salts, one being blue, the other reddish-yellow.ORGANIO CHEMISTRY. 611 'i\Jt,-~'-~~drozyrosindosie, C2,H,4N20,, is formed when sodium phenylrosindulinesulphonate is heated with 10 per cent. sodium hydroxide (10 parts) at 220°, the sodizorn salt separating in red leaf- lets as the liquid cools. The compound cryatallises from alcohol in prisms having a dark, brownish-green reflex ; the alcoholic solution exhibits greenish fluorescence, and the solution in concentrated sul- phuric acid is reddish-violet, becoming yellow on dilution. Nt2-2'- Hydrozy?-osincZo?ie is obtained by the same method from, the corresponding sulphonic acid, forming a sodiuln salt which crys- tallises in lustrous leaflets, and dissolves in 400 parts of water.The hydrochloride crystallises in compact, red prisms having a green reflex, 2nd the alcoholic solution exhibits greenish-yellow fluorescence. Hydroxyrosindone crystallises f Porn alcohol in yellowish-red leaflets ; its solution in concentrated sulphuric acid is magenta coloured, i n alkalis brownish-yellow, and in alcohol greenish-yellow, exhibiting fluorescence of the same tint. Symmetrical anilidophenylindzdiue is prepared by gently heating a mixture of nitrosopheny 1-a-naphthylamirie hydrochlorida, aud di- p henylmetaphenglenediamine dissolved in alcohol ; the green liquid soon becomes blue, and is then set aside for 12 hours. The base separates as a bluish-violet powder, and crystnllises from benzene in leaflets having a greenish lustre.The kydrochZoTide is deposited from the alcoholic solution as a, bluish-violet, crystalline powder. When the salt is heated with glacial acetic acid and concentrated sulphuric acid for nine hours at 200-22O0, B2-4-hydroxyrosindone is formed, this substance being also produced by the action of hydrochloric and glacial acetic acids on amidophenylrosinduline (ibid., 335). The compound obtained from nitrosodimethylaniline, a-naphthyl- amine hydrochloride, and aniliiie, which was regarded as B,-dimethyl- isorosinduline (ibid., 336), has, in reality, the constitution This view of its structure receives support from the conversion of t h e substance into Bz-4-hydroxyrosindone by means of hydrochloric acid at 180°, and also from its formation by the action of nitrosodi- met8hylaniline on P-phenylnaphthylamine, as, from the constitutional formula now put forward, it is seen to be a derivative of p-phenyl- naphthylamine.The action of nitrosodimethylaniline on p-phenyl- naphthylamine gives rise to an isomeride which forms reddish-browu crystals, the solution in alcohol being reddish-violet, and becoming magenta-red when treated with mineral acids ; the solution in con- centrated sulphuric acid is green, but neither the base nor its salts exhibits fluorescence in solution. When benzeneazo-a-naphthylamine hydrochloride is heated with phenol for an hour at 120-130°, rosirlduline, CZ2Hl5NY, and " naphthyl, red," C26H,,N4, are produced (ibid., i, 721). The former is separated by means of the ready solubility of its hydrochloride in dilute alcohol ; i t crystallises from benzene in aggregates of leaflets and melts at 198-199O.Naphtbyl-red is a brownish-red, crystalline612 ABSTRACTS OF CHEMICAL PAPERS. substance, having a green iridescence ; it is somewhat solable in hot water, and absorbs carbonic anhydride from the air. The ILydrochz,,- ride crystallises from dilute alcohol in long, golden needles ; the solu- tion in concentrated sulphuric acid is yellowish-green, becomirlg pi& and finally reddish-violet on dilution. Although not ver.y soluble iu cold water, the reddish-violet solution exhibits an intense fluorescence resembling that of Magdala red. The pZatitzochZoride is a brown, crystalline powder. Ntz-4-Am.;do?zaphthindone, C26H17N30, is obtained by heating fhe hydrochloride of naphthyl-red.with glacial acetic acid and Concen- trated hydrochloric acid for nine hours at 190-200" ; it crystallises from alcohol in beautiful, green plates. The solutions in alcohol and benzcue exhibit fiery-red fluorescence, and the solution in concentrated sulphuric a,cid is blue by reflected, red by transmitted light, becoming brownish-yellow, and, finally, red on dilution. The hydrochloride crystallises in needles with a bronze lustre. The Nt-4-hydroxy- naphthindone, obtained by decomposing anilidophenylnaphthinduline, is also formed when the hydrochloride of naphthyl-red or amido- naphthindone is heated with acetic and hydrochloric acids for about 20 hours at 200-220". When commercial Magdala red is covered with hot benzene, heated with alcoholic potash for 15 minutes, filtered, and again boiled with benzene, it is separated into two bases, one of which, CmHI9N3, remains dissolved in the benzene, whilst the residue consists of the amido-derivative, C3,,HZ0N4.The solution of the former in concentrated sulphuric acid is blue, but the addition of a few drops of water causes the liquid to appear yellowisb-green by transmitted light and pink by reflected light. The second base forms a yellowish-green scdution i n concentrated sulphuric acid, the liquid becoming brownish - pink and ultimately red on dilution, ~ d . d s t both bases exhibit fluo- rescence in alcoholic solution. The base C30HI9N3, symmetrical meso- a-na~hth!!l,7(Z23hthii~duline, crystallises from benzene in brownish-red leaflets ; when beated with glacial acetic and concentrated hydrochloric acids for 15 hours at 220°, it yields meso-naphthylnaphthindone, C,oH,O<N(C,oH,)> N-- C,oH6, which separates from alcohol in prismatic crystals, and dissolves in concentrated sulphuric acid with a bluish- green coloration.Magdala red is obtained from the residue left by the commercial substance after treatment with alcoholic potash and benzene ; when this is dissolved in alcohol with the addition of sulphuric acid, the sulphate is obtained in crystals with a bronze reflex. The base, C30H-20N4, crystallises in small prisms with a green reflex ; they con- tain ether, but this is completely removed in the vapour of boiling xylene; it dissolves sparingly in benzene and ether, but is more readily soluble in methylal. The aqiieous and alcoholic solutions do not exhibit fluorescence, but they absorb carbonic anhydride from the air, developing a vivid red fluorescence which disappears on the addi- tion of alkalis.When the alcoholic solution of the sulpliate is treated with sulphuric acid and sodium nitrite, the base, C,,,H,,N,, is formed.

By THEODOR ZINCKE and M. SCSMTDT (Annaleiz, 1895,286,27-57 ; compare this vol., i, 150).--The diacetyl derivative of naphthazarin crystallises from hot, glacial acetic acid in lusti-ous, golden-yellow needles, and melts at 189' ; it dissolves in concentrated sulphuric acid with development of a red coloration, and is slowly hydrolysed by alkalis.1 : 4 : 1' : 2'-TetrahydroxynaphthaEene is obtained by reducing naphthazarin, suspended in alcohol, with stannous chloride and hydrochloric acid ; it crystallises from alcohol in yellow needles, and melts and becomes red a-t 154'. Very dilute solutions i n common solvents exhibit a greenish fluorescence, and the aqueous solution becomes red on exposure to air ; the solution in concentrated sul- phuric acid is greenish-yellow. The tetracetyl derivative has been already obtained (loc. cit.) . Tetrahydroxynaphthalene mpidly under- goes oxidation when an alkaline solution is exposed to air, treatment with aqueous sodium hydroxide giving rise to a green salt, which gradually yields a blue solution, from which the sodium derivative of naphthazarin separates in coppery leaflets.Attempts to convert tetrahydroxynaphthalene into a diquinone were unsuccessful, the mbs tance being indifferent towards nitrous acid, atmospheric oxygen, and nitric acid, whilst ferric chloride oxidises i t to naphthazarin. The dichlorinated additive compound of naphthazarin [0 : (HCI), : 0 = 1 : 2 : 3 : 41, is prepared by the action of dry chlorine on naphthazarin suspended in cold chloroform ; it ci-ystallises in dark-yellow, compact prisms, and decomposes at 220O. When treated with boiling alcohol, 1 mol. HC1 is eliminated, and alkalis and alkali carbonates convert it info the bliie sodium derivative of nionochloronaphthazarin. Monochloronaphthazarin is obtained by dissolving the dichlorinated additive compound in boiling glacial acetic acid, and heating on the water bath with aodium acetate dissolved in the niinimnm quantity of water; it crystallises from hot glacial acetic acid in greenish-black needles having a metallic lustre, and melts at l i 6 O .The diacetyl derivative crystallises from acetic anhydride in golden-yellow needles, and melts at 1 9 2 O ; it is formed when chlorine acts on the diacetyl derivative of naphthazarin.

Tetrachloronaphthazarin is obtained from the foregoing compound by reducing it in hot glacial acetic acid solution with stannous chloride ; it is also formed when the hexachloro-derivative is heated with hydrochloric acid at 160' for 10-12 hours, dichloromaleic acid being produced at the same time. It crystallises from glacial acetic acid in dark red, lustrous plates, and melts at 244' ; the salts are deep blue, and dissolve with difficulty in water and alcohol. The com- pound is indifferent towards alkalis, this behaviour being probably due to the sparing solubility of the alkali salts ; these, however, yield naphthazarin very easily when a solution in alcohol or glacial acetic acid is heated with zinc dust.The acetyl derivative crystallises from acetic anhydride in golden-yellow needles, and melts at 244'. Anilido- trichloronaphthasarilz is formed when a solution of the tetrach1oi.o- derivative in glacial acetic acid is boiled with aniline ; it crystallises from the acid in brown needles, and melts at 224'. The alkali salts are blue, and the solution in'concentrated sulphuric acid is blue, becoming red when heated. The action of chlorine on tetrachloro- naphthazarin, dissolved in gla.cial acetic acid, converts it into the hexnchloro-derivative already described ; the same effect is produced by bleaching powder.C1 OH H()//\/\\C1 Tetrachlorotetrahydrox ynaph f hlene, 1 [I I,, , is obtained by the act~ion of stannous chloride on the hexachloro-derivative and tetrachloronaphthazarin ; the product is separated as rapidly as possible, and excess of the reducing agent must be avoided. Solutions of the compound in alkalis are green, the surface of the liquid rapidly becoming coated with n blue, coppery oxidation pro- duct. The tetracetyl derivative crystallises from acetic anhydride in slender, colourless needles, and melts at 850'. Tetrachlorotetraketotetrahydronaphthulene is formed when the hexa- chloro-derivative is cautiously melted, chlorine being evolved. It sublimes when strongly heated, and crystallises in lustrous, yellow leafiets resembling mosaic gold in appearance ; common solvents and fuming nitric acid dissolve it with difficulty. Reduction in glacial acetic acid with stannous chloride gives rise to tetrachloronap htha- earin, tetrachlorotetrahydroxynaphthalene being formed when excess of the reducing agent is employed ; tetrachloronaphthazarin is also cly&ORGANIC CHEMISTRY.615 formed by the action of hot hydrochloric acid. The qninone dis- solves in hot quinoline or phenol, giving ~ i s e to red compounds. Orthopheiiylenediamine unites with it, forming an eurltodole which is isonieric with the similar compound obtained from tetrachloro- naphthazarin, the alcoholic solution being blue, and the ammonium salt sparingly soluble. Aniline converts the quinone into the diani- lido-derivative, which cry stallises from glacial acetic acid in needles having a metallic lustre; the solution in aqueous soda is violet.Concentmted hydrochloric acid a t 1 50' removes one aniline group, which appears to be replaced by an atom of chlorine. The eurhodole obtained from tetrachloronaphthazarin by the action of orthophenylenediamine crystallises in greenish-brown leaflets and needles exhibiting a metallic lustre; it does not melt below 250', and dissolves with difficulty in common solvents. The sodium salt is violet, and dissolves sparingly in alkalis, the solution in alcohol being blue. The triacetyl derivative crystallises in yellowish, microscopic prisms, and does not melt below 250'. Another acetyl derivative is obtained by boiling the alcoholic solut,ion of diacetyltetrachloro- naphthazarin with orthopbenylenediamine ; i t yields the triacetyl derivative when treated with boiling acetic anhydride.In order to compare the properties of tetrachIoronaphthazai*in with the behaviour of a-nanhthaauinone derivatives towards ortho- phenylenediamine, the following compounds have been prepared. up-Dichloronaphthaphenazine, 8C1*c6H4*7:N>C,H,, is obtained by cc1-- C:N adding orthophenylenediamine to a hot solution of dichloro-p- naphthaquinone in glacial acetic acid ; it crystallises in slender, gellow needles, and melts a t 202'. up- H y drox~chloronavhtha~heizuzine (p-chloronapht heurhodole) , is prepared by the action of the base on dichloro-a-naphthayuinonc and hydroxychloro-a-naphthaquinone ; i t crystallises in brownish-red needles which exhibit a metallic lustre.The solution in hot, aqueous soda is red; dilute aqueous alkali dissolves it when cold, further addi- tion of soda causing separation of the sodium derivative in yellowish- red leaflets and needles having a greenish lustre.

The solution in alkalis is blue, rapidly becoming brownish-red, whilst concentrated sulphuric acid dissolves it? developing a deep blue coloration. The hydrochloride separates from the blue solution in lustrous, green needles, which closely remmble magenta ; it is rapidly decomposed by alcohol, and less easily by water, undergoing but slight change on exposure to air. The monacetyt derivative crystallises from hot benzene in retl, lustrous needles, and melts at 133"; it is insoluble in cold aqueous alkali, undergoing hydrolysis when heated, this result being also produced by hydrochloric acid.The diacetyt derivative is formed when sodium acetate is employed ; it crystallises from hot alcohol i n orange plates, and nielts at 153".

Azo Colouring Matters. By EUGEN BAMBERGER and FRANZ MEIM- BERG (Ber., 1895, 28, 1887--1897).-Bamberger’s statement (this vol., i, 352) that normal and iso-diazo-compounds yield identical products, is now shown to be true for the products obtained by the action of methylaniline and of ethylaniline on sormal and iso-para- nitrodiazobenzene.The authors confirm Hantzsch’s statement (this vol:, i, 418) that the two isomeric paranitrophenylazo-a-naphthols, obtained by treat- ing paranitrodiazobenzene hydrate with a-naphthol, are position isomerides, being respectively para- and ortho-derivatives of naph- thalene. M. 0. F. The following new compounds are described. Orthonitrophenylparazo-a-naphthol, OH*C,,H6*N2*c6H4*No2, crystal- lises in dark red needles, which have a bronzy lustre. It decomposes and melts a t 244-245’, and is readily soluble in hot xglene and xmylic alcohol.When reduced, and then treated with ferric chloride, it gives a-naphthaquinone. OH* CloHs*N2* C6H4*N02, is (1) @,2) (1) formed, together with the above para-compound, when orthonitro- dinzobenzene methyl ether is treated with a-naphthol. It crystallises in brownish-red, glistening needles, melts at 215-21 6’, and is soluble in conce;itrated sulphuric acid. It does not yield a-naphthaquinone. Both the ortho-compouxd and the para-compound are aoluble in itqueous alkalis. Paranitrophenylazodiethylorthotoluidine, NOz.C6H,*N2*C6H,D/Ie*NEf2, forms dark orange-red needles, which have a brilliant lustre, and melt at 107.5-108’. Diethylorthotoluidine, however, gives no dye with paranitroisodiazobenzene.When paranitrophenylazomethylaniline, dissolved in acetic acid, is added to a-naphthylamine and the mixture is allowed to remain, Meldola’s paranitrophenylazo-a-napht hylamine (m. p. 851-252O) separates. a- and /3-naphthol are also capable of replacing the miline group from both paranitrophenylazo- me thy laniline and -ethyl- aniline. It is also shown that when diazobenzene chloride reacts with alkaline a-naphthol, 33 per cent. oE bisphenylazo-a-naphthol is formed ; this fact has been overlooked by previous investigators. The compound melta at 190-191’, whereas Krohn (Abstr., 1889, 152) gives 183’ as the melting point. Bispa.ratolylaso-ar-naphtho1 is formed, together witah paratolylazo-a- naphthol, by the action of diazotoluene chloride on an alkaline (1) (4, 2) ( 1) Orth onitrophen y lor thaso-a-naph t ho’l, (1) (2)ORQANIC CHEMISTRY.619 solution of a-naphthol. I t is insoluble in alkalis, and crystallises in dark violet needles which melt at 205-206'. Bispayabromophenylazo-a-naphthol, OH*C,,H,(Nz*C,H4Br)z, crystal- lises in green, glistening needles, which melt at 23.3-235". It is sparingly soluble in alcohol, ether, and chloroform, but readily in hot benzene or toluene. According to the authors, parabyomophenylazo-a-lzaphthl crystal- lises in dark brown needles with a greenish iridescence, and melts at 237-238', and not at 185' or 195-196', as Margary (Abstr., 1885, 546) states. 3. J. S. Naphthylindoxazen. By R. J. KKOLL and PAUL COHN (Ber., 1895, 28, 1872-1873) .-The oxime of orthobromophenyl naphthyl ketone (this vol., i, 477) is obtained when an alcoholic solution of the ketone is heated for 196 hours with an excess of hydroxylamine hydrochloride and a few drops of hydrochloric acid in a soda-water bottle ; the yield is not good, as a considerable portion of the ketone remains unaltered.The oxime, which crgstal!ises in small needleu, melts at 165O, and is only sparingly soluble in alcohol or light petro- leum, but readily in ethylic acetate. It is not soluble in alkalis, and does not reduce Fehling's solution. When the oxime is heated with alcoholic potash, naphth y linaoxazen, formed ; this crystallises in small needles, which melt sharply at 98-93'. Terpenes and Ethereal Oils. By OTTO WALLACH (Annalerb, 1895, 286, 90-118 ; compare Abstr., 1894, i, 46, also Semmler, ibid., 339).By OTTO WALLACH and 0. SCHARFENBEltG.-The authors enu- merate reasons for regarding thujone, tanacetone, and salvone as chemically identical, and attribute the difference in their physical properties to admixture with foreign substances. For the purposes of this investigation, thujone has been prepared from oils of thuja, tansy, wormwood, and sage ; the ethereal oil of Artenaisia Barrelieni is also a profitable source of the ketone. Three isomeric thujonoximes have been prepared, and the respective amines obtained on reduction are found to be individual substances. Thujonoxime, melting at 90°, is obtained by treating the isomeric oxime (m. p. 54-55') with phosphorus pentnchloride (Zoc. cit.) ; itl crystallises from light petroleum in large, transparent, monoclinic prisms; a : b : c = 1.285 : 1 : 1.377, /3 = 116' 28'.The alcoholic solution is feebly dextrorotatory . Unlike the isomerides, the o+me is not volatile in an atmosphere of steam. When thujonoxime, melt- ing at 54-55", is dissolved in concentrated sulphuric acid maintained at a temperature below 50--60°, it is converted into an optically inactive isorneride, which crystallises from methylic alcohol in long needles and melts at 119-120° ; i t dissolves readily in water, and is volatile in an atmosphere of steam, slowly becoming hydrolysed when treated with boiling dilute acids. Thujonamine, obtained by reducing with sodium and alcohol the oxime melting at 54-55', boils at 195', has a sp. gr. of 0.8735 and a refractive power [nID = 1.4608 at 20': being identical with tanacetyl- J.J. S.620 ABSTRACTS OF CHEMICAL PAPERS. amine obtained by reducing tanacetoxirne (Semmler, Abstr., 1893, i, 107). It absorbs carbonic anhydride with great readiness, foyming the carbonate, which melts at 106-1 07' ; the nitrafe and hydrochZoride melt at 167-168' and 260-261' respectively. The phenylcarbamide crystallises i n white prisms and melts at 120°.. The isomeride obtained from the oxime melting at 90" boils at 193', and has a sp. gr. of 0.875 and a refractive power [nID = 1.4625 at 20': i t absorbs carbonic anhydride slowly. The nitrute and hydro- chloride melt a t 184' and 216' respectively, and the phenylcarbarnide melts at 110'. The isomeride (isothzljonamine) obtained from the oxime melting at 119-120', boils at 200-201', and has a sp.gr. of 0.865 and a refrac- tive power = 1.468 at 20' ; it absorbs carbonic anhydride very feebly. The nifrate and hydrochloride melt, at 163' and 180-181' respectively ; the curbarnide, NH2*CO*NH*CloH17, melt5 at 158-159', the phenylcadmwiide crystallises in white needles and melts at 178", and the phenylthiocai.bamide crystallises from methylic alcohol in needles and melts at 152-153'. Thujene (Abstr., 1'893, i, 1061, obtained by distilling the hydro- chloride of thujonamine (from thujonoxime, m. p. 54-55'), is identical with tanacetene prepared by a similar method from tan- acety lamine (Semmler, Zoc. cit.). Is0 thujonamine hydrochloride, when submitted to dry distillation, also yields thujene, which boils at 170-172', has a sp.gr. of 0.836 and a refractive index [nID = 1.47145 at 22' ; the identity of this hydrocarbon with thujene ob- tained from the sources already mentioned has not, however, yet been established. T hujene contains two ethylenic linkings, and differs from all other terpenes in developing an intense, red colora- tion when a drop of concentrated sulphuric acid is added to its solution in glacial acetic acid. Isothujone, CloH,,O, i R obtained by heating thujone with a mixture of concentrated sulphuric acid and water (2 parts) for 8-10 hours in a, reflux apparatus, the product being subsequently carried over in a current of steam. The points of difference between thujone, iso- thujone, and carvotanacetone (Semmler, Abstr., 1894, i, 339) are collected in the following table.B. p. sp. gr. [12]D. M.

The ready conversion of thujone into isothujone by means of sulphuric acid suggests a method of separating laevo-fenchone from thujone, as the boiling point of the former is considerably below that of iso- thujone. Dihydroisothjole or thujameidhole, C,,H2,0, is obtained by reducingORGAN10 CHEMISTRY.621 isothujole with alcohol and sodium ; it is a viscous liquid, having the odour of terpineol. It boils a t 211-212', has a sp. gr. of 0.9015 and a refractive power [ n ] D = 1.46306 at 20'. Thujamenthone, CI0Hl80, is obtained by oxidisinp the foregoing alcohol in glacial acetic acid solution with chromic anhydride; i t boils at 208-211', has a sp. gr. of 0.897, and a refractive power [nID = 1.4541 a t 20". The ketone is isomeric with mentbone; it is optically inactive, and bas the odour of methone. The oxime melts at 95', and the semicarbnzide derivative crystallises in needles ant1 melts at 178'. Whilst endeavouring to identify thujamenthole and thujamenthone with an alcohol and ketone already known, i t was found that tetra- hydrocarveol and dihydrocarvotanacetol are identical, but diffei- from thujamenthole, whilst tetrabydrocarvone is identical with dihydro- carvotanacetone and differs from dihydroisothujole.When thujone is heated in acetic acid solution with feri*ic chloride, carvacrol is formed, and the same compound is procluced, together with carvotanacetone, when thujone is heated alone a t a high tem- perature. By OTTO WALLACH and JAMES T. CONROY (Absti-., 1893, i, 598).- When tribroniothujone is treated with sodium and methylic alcohol, it yields the compound OH*CloHllBr*OMe, which forms colourles5 crystals and melts atD 166-157' ; it is phenolic in character, forming a niti-o-derivative, and the acetyl compound crptallises from methylic: alcohol, and melts at 63-64'.The dimethyl ether, which melts a t 42-43', is insoluble in alkali, and yields a nitro-derivative by the action of strong nitric acid. The cornpowad, OH*CloHIIBr.OEt, is formed when tribromothujone is dissolved in ethylic ahohol a d treated with sodium; it melts a t 14-145', and resernbles the methylic compound in geneleal behaviour. An attempt was made to determine the relative position of the oxygen atoms in these com- pounds. Tribromothnjone W B F , dissolved in glacial acetic acid, and heated on the water bath with sodium acetate; on removing the acetic acid, acidifying, and extracting with ether, a product was ob- tained, which, when oxidised with ferric chloride, yielded a yellow oil having a pronounced odour of quinone. It is, therefore, probable that the hydroxyl groups are in the para-position, and the authors regard the methylic compound (m.p. 156-157') as having the constitution C Pr<d OMe). CBr>CMe. Terpenes and Ethereal Oils. Brominated Derivatives of the Carvone Series. By 0. WALLACH (Anualen, 1895, 286, 119- 243).-Racemic carz'one fribromide, CloHla0,HBr,Br2, is obtained by dissolving a mixture of equal quantities of d- and I-carvone in glacinl acetic acid saturated with hydrogen bromide, and having cooled the liquid, adding a solution of bromine in glacial acetic acid ; it separates from ethylic acetate in magnificent, monoclinic crystals, and melts at 74-76". Limo- and dextro-carvone tetrabromides melt at 129-122O ; the racemic tetrabromide melts at 107-109O (compare A4bstr., 1894, i, 538). By the further action of bromine on the liquid from which ('H-C(0H) M.0. F.622 ABSTRACTS OF CHEMICAL PAPERS. the tetrabromides are removed, the a-peiatabromide is formed ; the active modifications melt and decompose at 142-143', and the isacemic at 124-126', the latter being obtained by mixing the laevo- and dextro-pentabromides in equal proportion, and also by the action of bromine on the racemic tetrabromide (m. p. 107-109"). On bro- mination, dextro-carvone tetrabromide yields the /3-psntabromids, which is dextro-rotatory, and melts at 86-87" ; the derivative from lavo-carvone tetrabromide has the same melting point, and the racemic P-pentabromide melts at 96-98'. When the carvone bromides are reduced with zinc dust and glacial acetic acid, carvone is regenerated ; carvone tetrabromide dissolves in fuming nitric acid, undergoing moderate oxidation when the solution is heated, and yielding a nitro- genouti acid, which is decomposed by alkalis with formation of nitrous acid.On submitting a solution of racemic carvone tribromide in ethylic or amylic alcohol to the action of a current of dry ammonia, an un- htable base is formed, of which the salts in aqueous solution yield crystals of a compound having the composition C,oEI,40, ; it separates from alcohol in well-defined crystals, melts at 69-70", and boils at 123' under a pressure of 10 mm. The substance is insoluble in boiling aqueous soda ; it is unsaturated, and the dibromide melts at Dihydrocurvone tribromide is obtained by the action of bromine on the d- or Z-dibromide ; it melts at 88-89", and the racemic modifica- tion at 65'.The ketonic compound, C1,,H160, obtained by heating trihydroxy- hydrocymene with dilute sulphuric acid (Abstr., 1894, i, 44), the author calls carvenone ; on bromination, it yields racemic dihydro- carvone dibromide. The author has already shown (this vol., i, 59) that terpineol may be converted into carvone, and the forrna- tion of carvenone from an oxidation product of terpineol affords a, means of transforming the alcohol into dihgdrocarvone. When di- hydrocarvone is heated with dilute sulphuric acid i n a reflux apparatus f o r 10 hours, carvenone is formed, and the production of this substance when trihydroxyhydrocymene is heated with dilute acid depends on the intermediate formation of dihydrocarvone. The abnormal re- fractive power of carvenone and isothujone has as yet received no explanation, the properties of the substances leaving no doubt as to their ketonic character.Carvacrol is prodaced when dihydrocarvone and carvenone are oxidised with ferric chloride. The author discusses the conditions affecting the formation of a, racemic compound on mixing d- and I-modifications ; it is found tha6 such combination is almost invariably accompanied by contraction. I n connection with this subject, the following crystallographic in- formation has been supplied. Inactive carvone dibromide crystallises in the triclinic system, a : b : c = 0.5057 : 1 : 0.5492; a = 90" 16', p = 107' lS', y = 76" 50'. The crystals of i-carvone tribromide are monoclinic, a : b : c = 0.7154 : 1 : 0.7459; 13 = 98' 58'.Dextro- and lavo-carvone tribromides form rhombic hemihedral crystals ; Q : b: G = 0.4729 : 1 : 0.7939. The d- and Z-carvone tetrabromides also form rhombic hemihedral crystals ; a : b : c = 0.7078 : 1 : 0.8704. The inactive 94-9 6'.ORQANIC CHEMISTRY. 623 tetrabromide forms monoclinic crystals ; a : 6 : c = 0.7091 : 1 : 0,4605 ; B = 100' 32' 45". The d- and l-cai-vone tetrabromides form monoclinic hemimorphic crystals; a : 71 : c = 0.7842 : 1 : 0.6006; /3 = 98' 6'. M. 0. F. Essence of Cannabis Indica. By G. VIGKOLO (Ga,zzetta, 1895, 25, i, 110--114).-The essential oil of Cannabis indica, purified by distillation in a current of steam and extraction with ether, is a mobile liquid boiling at 248-268' ; after repeated distillation from metallic sodium in order to remove a stearoptene, i t yields a, sesqui- terpene, C,,H,,, as a.mobile, colourless oil of aromatic odour, which boils at 256', and has a density of 0.897 at 15*3', and is slightly laevo- rotatory. This soon resinifies on exposure t o air, and on adding con- centrated sulphuric acid to its chloroform solution the liquid becomes first green, then blue, and red on heating. The author concludes that the " cannabene," prepared from this essence by Personne, was a mixture. Constitution of Isonitrosoketones. By GIUSEPPE ODDO (Ber., 1895,28, 1925-1916).-I~onitrosocamphor, whether obtained by the method of Claisen and Manasse, by the action of sodium ethoxide and amylic nitrite on camphor (Abstr., 1889, 619), or by the author's method of treating camphorcarboxylic acid with sodium nitrite (Abstr., 1893, i, 660), behaves in most reactions in the same manner.Both products are converted into camphorquinone by nitrous acid, and into camphorimide by sulphuric acid, and with ethylic iodide the salts yield the same ethylic salt, melting at 73', and crystalli- sing with Q mol. H,O ; benzok chloride also converts them into the same benxoyl derivative, melting at 127-1S8'. Towards acetic chloride, however, the two behave in a totally different manner, the isonitrosocamphor obtained from camphorcarboxylic acid always yielding the anhydride, ( CsH,4<8G):, which melts at 172', and yields a monozinze and a rnonohydp.azone; the product obtained by Claisen and Manashe's method, on the other hand, is converted into a substance of unknown constituiion melting at 2 1 2 O , if treated directly with acetic chloride ; if, on the other hand, the reaction takes place in ethereal solution i t is converted into an isomeride melting at 151', which dissolves readily in alkalis, and yields liquid methylic and ethylic derivatives boiling at, 270' and 278' respectively.It is no longer converted by nitrous acid into camphoi.quiuone, and has HN C*HM probably the constitution b>C<bo . This difference in tha behaviour of the isonitrosocamphor obtained by different methods is probably due to the fact that the two com- pounds are stereoisomerides, the one obtained by the author's method being anti-nitrosocamphor, whilst Claisen's is syn-isonitrosocamphor.Campholenic Derivatives. By AUGUSTE BPHAL (Conipt. rend., 1895, 120, 1167-1170) .-The results described by Tiemann (this vol., i, 426) agree in general with those obtained by the author.

Tiemann's statements, that hydrochloric acid is without action on camphoroxime. and that the production of carnpholene when campholenic acid is heated with traces of sodium is due to the presence of campholenolactone, do not, agree with the author's results (this vol., i, 240 and 241), and it would seem that Tiemann has not distinguished between t.he two distinct lactones described by the author (this vol., i, 552).The con- stitution attributed by Tiemann to the active campholenic acids is not in accordance with Guerbet's results (Abstr., 1894, i, 254), nor even with his own observations.

It separates from light petroleum in tabular cr~ystals and melts a t 60-61'. Careful comparison of the base and its derivatives with hydrohydrastinine (Freund) and its salts establishes their identity, and the product of oxidation of methylene- dioxymethyltetmhjdroisoquinoline iR identical in every respect with hydrastinine obtained from hydrastine.In order to show that condensation of meta-substituted derivatives of benzylideneamidoacetal takes place in the para-position with regard to the suhstituent, the oxidation of 2 : 2'-ethoxymethyl- tetra.hydroisoquinoline was undertaken. The action of a 3 per cent, solution of potassium permangnnate in presence of alkali gives rise to an acid, C12H,3N05 + H20, which crystallises from chloroform and nielts at 100' ; the barium salt has the composition (C,2H,2N05 + H20)2Ba. Chromic acid oxidises this acid to ethoxymethylphthali- mide, OEt*C,H3<CO>NXe, which crystallises from alcohol in prismatic needles, and melts at 110-111 '.Ethozyphthnlic acid [COOH : COOH : OEt = 1 : 'L : 5j is obtained from the foregoing sub- stance by treating it with a boiliiig solution of potash (33 per cent.) for 15 minutes ; it crystalliaes from hot water in leaflets, containing coORGANIC CHEMISTRY. 627 1H20, and becomes anhydrous at loo', melting at 163". If kept for &I. 0. E'. some time at 220°, the substance melts at 80'. Phenylpyrroline and Pyridylpyrroline ; Constitution of Nico- tine. By AMS PICTET and PIERHE CR~PIEUX (Ber., 1895, 28, 1904- >NPh, is obtained by the distil- QH:CH CH:C€I 19 1 2) .-1 - Phen y lp y rroline, lahion of normal aniline mucate, the yield being fairly good. It has all the properties described by Kottnitz (this Journal, 1873,163), boils at 234O, is very volatile i n a, currcnt of steam, and colours pine-wood violet in presence of alcohol and hydrochloric acid.When distilled through a tube heated to dull redness, it is, to a large extent, con- verted into an isomeric pheuyl derivative, in which the latter group is combined with carbon. It can be separated from unaltered 1-phenylpyrroline by fractional crystallisation from light petroleum, in which. the latter is more readily soluble. It forms nacreous plates, which become pink on exposure to air, melts at 129', boils at 271-272' under 726 mm. pressure, volatilises in a current of steam, and sublimes in broad plates. It colours pine-wood violet, and, 011 oxidation, yields benzoic acid, proving that the phenyl group is corn- bined with one of the carbon atoms ; i t is, as yet, uncertain whether it is a 2- or 3-phenyl derivative, although, as Ciamician and Silber (Abstr., 1887, 59'7) have shown that 1-acetylpyrroline under similar conditions passes iuto 2-acetylpyrroline, it is probable that in the case of the phenyl derivative the 2-phenylpyrroline is also formed.1 : 3-PyridyZpyrroZine, CH<N-Hc>C*N<CH:l,H, is obtained in a similar manner to the phenyl derivative by distilling a mixture of 3-amidopyridiue and mucic acid; the product contains large quantities of unaltered amidopyridine, which may be partially re- moved by treating the product with water ; the residual oil is then boiled with acetic anhydride, and the 3-acetamidopyridine thus formed separated from the pyridylpyrroline by fractional distillation.The former crystallises in lustrous plates, melts at 131', boils at 326-327', and, like amidopyridine, colours pine- wood orange- yellow. 1-Pjridylpyrroline boils at 250.5-251' under 730 mm. pressure, has a sp. gr. of 1.044 at 24'/4O, and an odour somewhat resembling that of benzaldchyde ; i t colours pine-wood blue. The picrate crystallises in yellow needles, melting at 178' ; the platino- chloride i n pale yellow plates, melting and decomposing at 190" ; the mercurochloride in long, white needles, melting at 189'; and the nzethiodide in small, white needles, melting at 241". On heating, it undergoes intramolecular change even more readily than the phenyl derivative, yielding a c-phenylpyrroline, which is separated from the unaltered base by washing with light petroleum, and then dissolving the residue in benzene and precipitating with light petroleum.It forms a crystalline mass of microscopic, white needles, melting at 72', gives an orange-red coloration with very dilute ferric chloride, and a dark blue pine-wood reaction. The picrafe crystallises in well- developed yellow prisms, melts at 182', and is much less soluble in CH*CH CHXH -628 ABSTRACTS OF CHEMICAL PAPERS. boiling water than the picrate of the 1-pyridyl derivative ; the platiuocldoride, ( C9N2H&,H2PtC1, + 2Hz0, forms golden-yellow needles, and decomposes at 150" without melting ; the mercurochlor- ide crystallises in small, pale yellow needles, melting at 178-179O; and the nzethioditic in similar crystals, melting at 1$0-171°.The potassi,zwa derivative, obtained by the action of metallic potassium at the melting point, is a light grey, crystalline powder. The rccent investigations of Piiiner and others have shown that nicot,ine is probably a 1 : 2 : %methylpyridylpyrrolidine, By careful oxidation, nicotine loses 4 atoms of hydrogen forming nicotvrine. which, if' the above constitution of nicotine be correct. CH* CH . I ' >C*C<NMe.dH, or is the 1-methyl derivative CHXH must be CH< N-CH of the authors' synthetical pyridylpyrroline, if the pyritlyl group really occupies the 2-position. When the potassium salt oE the synthetical base is heated with methylic iodide, the potassium is displaced by methyl, but at the same time, it combines with methylic iodide, yielding the mathiodide of 2 : 3-pyridylpyrroline ; this crystal- lisee in long, yellow Iieedles, melts at 807", and colours pine-wood green.A direct comparison of this substance with the methiodide obtained from nicotyrine has shown that in all probability they are identical, but to prove this definitely, it is necessary to obtain larger quantities of the syiithetical compound. Nicotine. By ADOLE' PINNER (Ber., 1895, 28, 1932--1935).-A criticism of the recent paper of Oliveri (this vol., i, 4333, in which it is shown that the compounds obtained by the latter by the action of bromine on powdered nicotine hydrobromide have not the con- stitution assigned to them, but are in reality mixtures. The con- stitutional formula suggested by Oliveri, which had already been considered by the author, is quite incompatible with the recent results of the chemical and physical investigation of nicotine.H. (3. C. E. G. C. Action of some Inorganic Cyanides on Chlorocaffeine. By 31. GOMBERG (Amer. Chem. J., 1895, 17, 403420).-The product obtained by beating bromocaffeine with an alcoholic solution of potassium cyanide is identical with that previously obtained by similar treatment of chlorocaffeino (Abstr., 1893, i, 375), and is shown to be c~~e~necurbozylamide. When heated at 250" with phosphoric anhydride, it yields cyawca$ei'ne, C8H9Na02*CN, which crystallises in small prisms, melts at 151", and freezes at 109--110°; it sublimes unchanged, and dissolves in hot water, hot alcohol, methylic alcohol, chloroform, and hot benzene, but not i n ether.CyanocaBeine is only slowly converted into the amide when boiled with water or dilute alcohol, unless a little potassium cyanide is present, when the conver- sion is rapid and complete. Chlorocaffeine was heated with a solution of potassium cyanide inORGANIC CHEMISTRY. 62 9 (1) absolute alcohol ; (2) water ; (3) metliylic alcohol ; also with mer- curic cyanide in alcohol, and with potassium mercuric cyanide in alcohol; furtliermore, chlorocaffeyne was fused with potassium cyanide. It was found, however, that none of these methods yields so large a proportion of cyanocaffeine as that obtained by dehydrating the carboxglamide with phosphoric anhydride. By treating cyanocaffeine with sodium in amylic alcohol, crystals of an organic base, probably caff eylmethylamine, CsHgNIO2*CHZ*NH2, were prepared, but were not fully identified.Cafleinecarbozylic acid, CeH,N,O2*COOH, may be prepared from the amide by dissolving it in sulphuric acid (1 : 1) and passing a stream of nitrous anhydride through the solution until a few drops give no immediate precipitate OIL the addition of water ; water is then added to precipitate the carboxylic acid. I t forms silky, acicular crystals of sour taste and bitter after taste, and melts and decomposes at 225-226'; i t dissolves in hot water and hot alcohol, but not in chloroform, carbon bisulplzide, or benzene. The sodium salt, with 2H,O ; potussium, with 2H,O ; calcium, with 5H,O ; barium, with 5H,O ; coppey, with 4H,O ; arid the silver salt are described. The methylic salt melts at 201.5' (uiicorr.), and sublimes unchanged ; the ethylic salt melts at 207-208", and also sublimes unchanged.The author concludes by pointing out that the above compounds are the first compounds of caffeine in which the carbon of the CH- group has been liuked t o a new carbon atom. The ease with which caffeinecarboxylic acid loses carbonic anhydride when heated is in accord with the general nature of many acids in which the carboxyl group is attached to an unsaturated carbon atom. Thus the position of the carboxyl group is, to a certain extent, established and E. Fischer's formula for caffe'ine confirmed. A. G. B. New Alkaloi'd contained in Coffee. By PIETRO PALLADINO (Gazzetfcc, 1895, 25, i, 104--11@).-The author extracts the bases from ground coffee berries by repeated boiling with milk of lime, filters, treats the liqiior with lead acetate, and repeatedly extracts with chloroform to remove the caffeine.The aqueous liquor is then concentrated with the addition of sulphuric acid, and, after dilution and filtration, is precipitated with Dragendore's reagent ; a well- crjstallised double iodide of bismuth and caffearine (Abstr., 1894, i, 214) is thus nltimately obtained. Cafeurine hydrochloride, ClrH16N204,HC1 + H20, crystallises in small, colourless needles, loses water at 110", and melts at 180' with decomposition; it is very soluble in water, a.s is also the platlizochloride, C,4H16N,04,H2PtC16, which crystallises in long, red prisms. Caffearine, Cl4HI6N20,, crystallises in colourless, deliquescent needles, which slowly turn red in dry air, and melt and decom- pose at 140'; it does not sublime, has a feebly alkaline reaction, but no circular polarisation in solution.Its physiological action has not yet been fully investigated, but it seems to act as a narcotic poison.

By MARTIN FREI:ND and Huno MICHAELS (Annalen, 1895, 286, 248-255) ; compare Abstr., 1894, i, 58 and 477),- Narceineamide, C23H26N207 + HzO, is the substance specified in D.K.P. 58,394, under the name of methylnarcotamide; it is obtained by allowing narcotine metbiodide to remain in contact with alcoholic ammonia for several days. It crystallises from dilute alcohol, and contains lHzO, which is removed at 100"; the substance, when anhydroug, melts at 78", and in the hydrated condition at 125", becoming solid above this temperature, and finally melting a t 178".Narceinei-mide, C23H26N206, crystallises from alcohol in small. yellow needles, and melts at, 150" ; its Irydrochloride melts at 239-240" ; the nitrate at 224-225@ ; the hydrogen sulphate a t 194-195"; and the rnethiodide a t 244-245'. Narceonimide, C21H19N06, is obtained by heating the methiodide of narceyneimide with 30 per cent. aqueous potash, trimethylamine being eliminated ; i t crystallises from glacial acetic acid in slender, yellow ncedles, and melts at 177.5-178.5". Thephenylhydrazide anhydride of nameonic acid, C2,H2,N206, is formed when the alcoholic solution of the acid is boiled with phenylhydrazine ; it crystalIises from a mixture of alcohol and glacial acetic acid inwhite prisms, andmelts at 181-182'. The oxims anhydride, C21H,gN07, crystallises from glacial acetic acid in needles and leaflets, and melts at 201-202'.Monobromonarceonic acid, Cz,Hlg13rOe, is obtained by adding bromine (1 mol.) to narceonic acid in glacial acetic acid ; it separates from alcohol in white crystals, and melts at 171-172". Tribromonarceonic acid is formed when excess of the halogen is employed ; it melts at Z31-252". Hydrocinchonine, Hydrochlorocinchonine and Hydrochlor- apocinchonine. By OSWALL) HESSE (Ber., 1895,28,14'24-1426).- The author criticises some of the results published by Konek (this vol., i, 579). It is shown that commercial cinchonine always contains more or less hydrocincbonine, and that this is beyond doubt identical with Zorn's crystalline hydrocinchonine.When, however, pure cinchonine is rediiced with sodium amalgam, an amorphous hydrocinchonine, ClgH26N20, is obtained. According to David Howard the same product can be obtained from cinchonidine, and it must therefore be a tetrahydrocinchonicine. As v. Miller and Rohde (AnnuZen, 276, 109) have shown that cinchonicine has a very different molecular structure from cinchonine, it follows that this amorphous reduction product cannot be a simple hydro- cinchonine. If cinchonine is heated with concentrated hydrochloric acid during 48 hours at 8S0, or for a shorter time at loo", the chief product is hydrochlorocinchonine. As this compound is not acted on by t i n and hydrochloric acid, it follows that it, and not hydrocinchonine, is the chief product obtained on treating cinchonine with these reduc- ing agents. This hydrochloro-base is identical with the hydro- chlorocinchonine of Comstock and Konigs (Abstr., 1887, 1124) ; but is not, as Konek states, identical with Zorn's chlorocinchonide and The AydrochZoride melts at 236-237". M. 0. F.ORGANIC CHEMISTRY. 63 1. Hes se'2 hydrochlornpocinchonine ; Zorn's chlorocinchonide is really an additive compound formed by the addition of hydrogen chloride to apocinchmine, and is, therefore, hydrochlorapocinchonine. It is doubtful whether Konek's chlorocinchonide is hydrochlorocinchonine or hydrochlorapocinchonine. The two hydrochloro-bases may be dis- tinguished by means of their behaviour with alcoholic potash ; when treated with this reagent, hydrochlorocinchonine gives a-isocinchon- ine, which is dextro-rotatory, whereas hydrochlorapocinchonine gives ,%isocinchonine, which is laevo-rotatory. Action of Sodium and Amylic Alcohol on Cinchonine. By FR. KONEK Edler vox NORWALL (Ber., 1895,28, 1637-1641 ; compare this vol., i, 579) -When cinchonine is treated with sodium in boiling amyl alcoholic solution it takes up four atoms of hydrogen ; and the product, when treated with potassium nitrite and sulphuric acid, yields teti-nhyc~rocisacho1Li.)re ?Litrite, NO*C19H25N20,HN02, which crystallises in silky, yellow needles. The free base instantaneously yields a colourless additive compound with methylic iodide, from which fact the deduction is drawn that the four hydrogen atoms attach themselves to the quinoline ring, that nitrogen atom remain- ing unaffected which, in cinchonine itself, readily takes up mefhylic iodide, &c., to form colourless derivatives. J. J. S. C. F. B. Constitution of Aconitine. A Reply.-By WTNDHAY R. DUN- STAN and FRANCIS H. CARR (Bey., 1895, 28, 1379--1382).-A reply to Freund's criticisms (Bey., 1895,28, 192) on the autliors' work. Chrysanthemine. Rr FRANCESCO MARIKO-ZUCO (Gaxzetta, 1895, 25, i, 255--262).-0n heating chrysanthemine at 150--160" with concentrated hydriodic acid, decomposition suddenly occurs and methylic and ethylic iodides distil over ; the residue in the retort con- tains no chrysanthemine, but on dissolving it in m-ater, decolorising with sulphurous acid, and adding potassium bismuth iodide solution, tetramethylammonium bismuthiodide separates. From the mother- liquor, after precipitating the bismuth and iodine, a methylpiperidine- carboxylic acid, C5NH,Me*COOH, may be separated as its ascrochloride, C7Hl30,N,HAuCI,, which crjstallises in hard yellow prigms melting at 130" ; the acid itself is a syrupy liquid which ultimately solidifies to a hygroscopic crystalline mass. This decomposition of the aikalo'id supports the constitution previously assigned to chrysan- themine by the author (Abstr., 1892, 84) but in view of the optical inactivity of the alkaloyd he considers that the constitution J. J. S. is t,he more probable. w. J. P. The Alkaloids of Cannabis Indica and Cannabis Sativa. By FRANCESCO MARINO-ZUCO and G. VIGKOLO (Gazzetta, 1895, 25, i, 262-268) .-Various parts of the common hemp (Cannabis sativa) and of the Indian hemp (Cannabis indica) were exhaustively632 ABSTRACTS OF CHEMICAL PAPERS. extracted by boiling with water acidified with sulphuric acid, and the extract evaporated until it acquired a syrupy consistency, any inorganic salts being removed as they separated. I t was then diluted with water, decolorised with animal charcoal, treated with soda, and precipitated with potassium bismuth iodide, the double salt de- posited being subsequently converted into the hydrochloride of the alkalo'id in the usual way. The salt obtained from both varieties of Caiaiznbis forms a colourless, crystalline, deliquescent mass ; that from Cannabis mtim is physiologically almost inactive, but gives rise in the frog to temporary cardiac depression ; the hydrochloride from Cannctbis indics is, however, highly toxic and causes far greater depression OE cardiac activity than the preceding. By W. LUBOLUT (C'laenz. Ceiztr., 1895, i, 61 ; from Apoth. Zeit., 1834, 9, 8GS).-SalicSlscopole'ine is best prepared by Liebermann and Limpach's method of heating scopolin with salicy- Xde a t 230", and extractiq the base .with dilute hydrochloric acid ; it crystallises in white needles melting a t 105'. The hydrochloride, hgdrobromide, sulphate, and aurochloride are described. The plajino-- chloride crystallises with 2H,O in orange leaflets melting a t 205' and with 1H20 in red needles melting a t 212' ; numerous analyses show that the base has the composition Cl5HI7NO4. The acetyl and bencoyl derivatives of scopole'ine are described. Senecionine and Senecine. By ALEXANDRE GRANDVAL and HENRT LAJOUX (Compt. rend., 1895, 120, 1120-1123).-Se~ecio vulguris con- tains small quantities of two alkalo'ids, which the authors call sene- cionine and senecine. Both are precipitated by mercuric potassium iodide, and both crystallise readily from chloroform, in which they are easily soluble ; senecionine, however, is less soluble in alcohol than senecine, and is only very slightly soluble i n ether, which dissolves senecine readily. Senecionine, CleH2sNOs, crystallises in small, rhomboidal tables ; it has a feebly bitter taste, and a strongly alkaline reaction, neutral- ising acids with formation of salts, which do not crystallise readily. I t s rotatory power is [ a ] , = -80*49°. With a mixture of ferric chloride and potassium ferricyanide, i t yields a precipitate of Prussian blue, and with acidified potassium permanganate, it gives a violet coloration. Senecine has a very much bitterer taste than senecionine. It crystallises from ether in silky tufts, and forms a hydrogen tartrate, which crystallises readily from water in efflorescent needles. No crystalline hydrogen tartrate of senecionine could be obtained. Senecine yields a, precipitate of Prussiari blue with a mixture of ferric chloride and potassium ferricysnide, and a violetl coloration with acidified potassinm pernianganste. With sulphuric acid, a yellowish coloration, changing to reddish-brown wit11 a violet tint is obtained ; with nitric acid, a violet-red coloration, and a deep violet precipitate ; with sulphovanadic acid, a violet-brown coloration.

633 Organic Chemistry. Solubility of Iodoform in Alcohol and Ether. By GUSTAV VULPIUS ( Z e i t . anal. Chew., 1895, 34, 465 ; from Pharm. Centralhalle, [2], l4,117).-At 17-18', 1 part of iodoform dissolves in 67 parts of alcohol (of 90.5 vols. per cent.) or in 5.6 parts of ether. At the boiling point, 9 parts of alcohol dissolve 1 part of iodoform. The three forms in which iodoform comes into commerce differ only in the rate at which they dissolve. The statements in the German Pharmacopoeia are not quite correct. M. J. S. Action of Nitric acid on Saturated Hydrocarbons and their Derivatives, By MICHAEL KONOVALOFF (Ber., 1895,28,1852-1865 ; compare Abstr., 1894, i, 265, 277).-Diisobutyl is converted by dilute nitric acid at 105-110'into a mixture of nitro-compounds, whichchiefly consist of tertiary nitrodiisobutyl, N02*CMe2*CH2*CH2*CHMe2.This is a yellowish liquid, which boils a t 201-202'? has the sp. gr. 0.9396 at O/O', and the molecular refraction 44.76. The corresponding amine boils a t 145', and forms a h,ydrochZoride, which crystallises in tablets or thin needles, melting at 157-160'. When the nitro-compound is further heated with dilute nitric acid at 120-125', dinitrodiisobutyl, C8H,,(N02),, which is also R tertiary compound, is formed ; it crys- tnllises in colourless plates, and melts at 126125'. The diamine is a strong fuming base, which absorbs carbonic anhydride from the air and yields crystalline salts. DidrodiisopropyZ, which is formed in small quantity in the nitra- tion of diisopropyl, is also a crystalline substance, and melts at Diisoarnyl is also mainly converted into a tertiary nitro-compound by dilute nitric acid.2\Titrodiisoamyl boils at 125' (pressure = 22.5 mm.), but decomposes when distilled under the atmospheric pressure. It is easily reduced to an amine, which boils at 190". Nitroisopropylbenzene, which had previously been obtained by the action of dilute nitric acid on isopropylbensene, boils at 125-127' (pressure = 15 mm.) when pure, and has the sp. gr. 1.1176 at OjO". Normal butylbenzene is converted into a secondary nitrobutylbenzene, KO,*CHPh*CH,*CH,Me, by dilute nitric acid ; this boils at:151-152° (pressure = 25 mm.), and has the sp. gr. 1.0756 at O/Oo, and the molecular refraction 50.33. When its potassium derivative is treated with bromine, a monobromide is formed which melts a t 55-56'.The corresponding amine boils at 220--220*5O, and yields crystalline salts. Nitroisobutylbenzene, NO,-CHPh*CHMe,, is obtained in a similar manner to the foregoing compound; it boils at 145-146" (pressure = 25 mm.). The monobromide is an oily liquid ; the amiiae boils at 213*5-215', and yields crystalline salts ; the hydro- chloride melts at 275-277', the picrate at 166--168O, and the oxalate at 120.5-122°. The sodium derivative of the nitro-wnapound has the 206 -208'. VOL.

Tertiary butylbenzene also yields a nitro-compound, which has not yet been obtained pure. Nitrod ibenz y I , N 02* C H P h*CHaPh, n b t ained in a similar rn an ner , volatiles slowly with steam.The hydrochloride of the amine melts at Toluene when heated at 100' with nitric acid of sp. gr. 1-12 is con- verted into pheiiyluitromethane, a yield of 50 per cent. being ob- tained. This substance is converted by reduction into benzylamine. Mesitylene is readily iiitrated by nitric acid of sp. gi-. 1.155 at, looo, and yields xylylnitromethane, C6H,Me2~CH2N0,, which crystallises in thick, four-sided prisms, melting at 46-47'. It is only slowly dis- solved by alkalis. The ainine boils at 22@-221°, and its hydrochloride melts at 245-246'. The facts here recorded confirm the conclusions previously drawn by the author from his experiments on nitration. The nitro-compounds are best obtained from their metallic deri- vatives by t h e action of hydrogen sulphide, boric acid, or carbonic anhydride.The reduction of the nitro-compounds described above always gives rise to the production of a .small quantity of a neutral substance, probably an aldebyde, ketone, or alcohol, in addition to the amine. A. H. Reaction for Primary and Secondary Nitro-compounds. By MICHAEL KONOVALOFF (Bey., 1895, 28, l%O--1852).-The reaction with nitrous acid (V. Meyer) is not well shown by nitro-compounds containing more than six carbon atoms; on the other hand, such compounds may readily be detected in the following manner. The substance to be tested is shaken with a little concentrated aqueous potash or sodium ettioxide, and the resulting salt extracted with a little water; the aqueous solution is then phced in a tube along with a small volume of ether or benzene, and ferric chloride added drop by drop, the tube being well shaken after the addition of each drop.A red coloration indicates the presence of a primary or secondary nitro- compound; this coloration is due to the formation of a ferric salt, and it is found that the solubility oE the ferric salt in ether, benzene, &c., increases with the molecular weight of tbe nitro-compound. 2 5 1 '5-25 2.5'. This reaction is very delicate, and is not:given by nitritea. A. H. Reactions of Aluminium Amalgam. By HANS WISLICENUS and LUDWIG KAUFYANN (Ber., 1895, 28, 1983--1986).-The first por- tion of this paper is a reply to the claims of priority of Radzie- wanowski (this vol., i,412) and of Cohen and Ormandy (this vol., ii, 394).In the second portion, it is shown that under certain cir- cumstances aluminium amalgam brings about reduction, even if all traces of water are excluded. Thus nitro-compounds, and all alkylic nitrites and nitrates, are reduced when treated with aluminium amalgam and absolute alcohol from which all traces of water ha,ve been removed by previous treatment with aluminium amalgam ; theORGANIC CHEMISTRY. 635 prodnct contains hydroxylamine derivatives, and also combined aluminium, which separates out as hydroxide on the addition of water. H. G. C. Removal of Phosphine from Acetylene prepared from Cal- cium Carbide. Compound of Silver Acetylide with Silver Nitrate. Prepamtion of Iodinium Compounds. By CONRAD WILLGERODT (Ber., 1895, 28, 2107-2115). -Acety!ene, prepared by the action of water on calcium carbide, contains phosphine, which can be detected by passing the gas through silver nitrate solution. The white precipitate produced by the acetylene is coloured dark by silver phosphide, whilst phosphoric mid passes into solution.The phosphine may be completely removed by passing the gas through bromine water. The compound of silver nitrate with silver iicetylide can be pre- pared in a, pure state by passing purified acet,ylene into aqueous silver nitrate ; it, is a white mass, which can be presewed in the dark for a long time. The temperature of explosion of the compound is about 230O. When the aromatic iodosochlorides are treated with the compound of silver chloride and silver acetylide, free from silver phosphide, and suspended in water, the chlorides of diallryliodinium bases are formed. The reactions which occur, for exaniple, when pheuylic iodosochloride is used are the €allowing.(1.) PhICI, + HC;CAg,AgCl = CHX*IPhCI + 2AgC1. (2.) PhICI, + H20 = PhIO + 2HC1. (3.) CHGIPhCl + 2HCl = C2H3C12*IPhCI. Dichlorethyl~henyliod~nium chloride, C,H,C12*IPhC1, crystallises in colourless prisms and decomposes at 178-1 79". Dichlorethy &am- iolyliodiuiuwa chloride crystallises in long needles OF prisms, which decompose at 178- 179'. Both of these chlorides form platino- chlorides. The nitrates of these bases can be obtained by the action of the chlorides on silver nitrate, or by the action of the iodosochloride on the compound o€ silver acetylide with silver nitrate.In the latter case, when phenylic iodosochloride is used, chZol.o2.i?ty~p!23erLyliodini.um nitrate, C,H2C1*IPh-NO, is obtained. This substance crystallises in prisms and decomposes at 150-153' EthenyElphenyliodinizim nitrade, CzHiIPhC1, is probably formed as a crystalline mass when phenyl iodosochloride acts on the compound of silver acetylide with silver nitrate suspended in chloroform. Dichlor- etltylphenyliolL7iniunz nitrate decomposes at 162'. Dicltloret~1/lphcn~liodin/ium iodide forms needles which melt and decompose a t 108". A. H. Acetylene and its Hydrate. By P.

I t is probable that Ansdell's acetylene contained a small quantity of chlorethylene. Acetylene crystals have no action on polarised light. The coefficient of solubility of the gas at 0" under a pressure of 4.65 atmos.is 1.6. Acetylene hydrate forms under the same conditions as the hydrates of nitrous oxide (Abstr., 1894, ii, 278) or carbonic anhydride (this vol., ii, 44) ; its crystals have no action on polarised light. Its vapour pressure is as follows : - t . . . . . a 0" 4.6" 7.0" 9.6" 15.0" p . . .. .. 5.75 9.4 12.0 16.4 33.0 At 16', the pressure is equal to that of the moist liquefied gas. Acetylene does uot combine with ice, and the hydrate is practically stable below - 0 ~ 5 ~ tinder ordinary pressure (P). The hydrate has the composition C2H2,6H20, and its hett of formation is +15*4 Cal. (Compare Zoc. cit.) C. H. B. Combination of Nitriles with Aluminium Chloride. By G. PEBRIER (Cowt,pt. Tend., 1895, 120, 1423-1426) .-Hydrocyanic acid, acetonitrile and propionitrile dissolve aluminium chloride with development of heat, yielding crystalline compounds of the general composition A12C16,4X.If the combination takes place in presence of carbon bisulphide, the products have the composition A12C1,2X. They are insoluble in carbon bisulphide, carbon tetra- chloride and light petroleum, and are rapidly decomposed by moist air and by water with liberation of the nitrile and aluminium chloride. Al2Cl6,4CH3*CPU' melts at 50-55" and decomposes at about 60"; A1,C1,,2CH3*CN melts at 104-105° and decomposes at about 110". Al2Cl6,4C2H5*cN crystallises in hexagonal tables which melt a t 58-60", and the liquid decomposes at about 80" ; A12C16,2C2H5*CN crystallises in slencler needles which melt at 70-80". When the acetonitrile and propioilitrile compounds are heated, some of the nitrile is given off and at about 360' a limpid liquid distils over and solidifies to crystals of the composition Al,CI,,CH,*CN, or A12C16,C2H5*CK, as the case may be.The former melts at 1$5-149", and the latter a t 95" ; both are decomposed by water into aluminium chloride and the nitde. Benzonitde, under similar conditions, yields the compounds A1,C 16,4C6H5*CN melting at 75", AlpCl~,2C&&*CN melting at 85" andORQANIC OEEMISTRY. 637 A12C16,CsH5*CN melting at 103-105'. In solubility and general properties, they closely resemble the corresponding compounds in the acetic series. When dry cyanogen is passed over gently heated aluminium chloride, a brown liquid product is formed with considerable develop- ment of heat.It crgstallises on cooling and is violently decomposed by .water. A similar product seems to be foimed in presence of carbon bisnlphide. It seems probable that compounds similar to those described in this paper are formed as intermediate products in Desgrez's process for the preparation of nitriles by the direct combination of cyanogen with hydrocarbom of the benzene series. Liquid cyanogen chloride seems to form no combination with alu- minium chloride, but a supersaturated solution is produced, ' and when it solidifies the heat developed causes explosive deconiposition of the whole mass, with production of solid cyinogen chloricle. C. H. B. Action of Halogens on Methylic Alcohol. By ANDRI% BROCHET (Compt. rend., 1895, 121, 130--13~?).-ChIorine attacks methylic alcohol more readily the higher the proportion of water present.The action of the moist gas on the alcohol of 99.5' in diffused daylight yields mainly formaldehyde. Most probably the primary product is chloromethylic alcohol, CH,Cl*OH, which in presence of hydrochloric acid is converted into symmetrical di- chloromethylic ether (CH,C1),0. The latter in fact separates as an oily liquid and can be isolated; in presence of water, however, i t readily decomposes into hydrogen chloride and formaldehyde. During tbe action of the chlorine, carbonic anhydride and carbonic oxide mixed with a small quantity of methylic chloride are continuously evolved. The carbon oxides may result from the action of the water on car- bonic chloride and the monochloride CHOC1, or from the dehydrat- ing action of the chlorine on the formaldehyde.If the methylic alcohol is heated, methylal is obtained together with large quantities of methylic chloride, carbonic anhydride, and carbonic oxide, the action being nccompaniecl by flame and by explosions, even in very diffused light. Bromine in presence of sunlight has practically 110 action on methylic alcohol at the ordinary temperature ; at loo', the action is slight; at 130-150', the action is somewhat energetic, the chief product being methylic bromide mixed with some carbonic anhydride, and with small quantities of carbonic oxide and formic acid if the bromine is not in excess. Iodine at 180-200° attacks the alcohol with dificulty, and small quantities of carbonic anhydride, hydrogen iodide, and methylic iodide are formed.A large proportion of the alcohol is, however, con- verted into methylic ether, and this compound can readily be pre- pared by beating the alcohol in sealed tubes with 5 per cent. of iodine. C. H. B. Nitro-Alcohols. By LOUIS HENRY (Conzpt. r e d , 1895, 120, 1265-1268).-Aldehyde and nitromethane dissolve in one another638 ABSTRAOTS OF OHEMICAL PAPERS. wit,hout any interaction, but in presence of water and a sn~all quantity of potassium carbonate, an action takes place with considernhle developinenL of lieat and nitroisopyopylic alcohol is obtained ; in presence of potalssium hydroxide the action is violent. Under similar conditions, formaldehyde yields a solid product, and pro- paldehyde yields secondary nitrobutylic alcohol.Isobutaldehyde reacts somewhat less readily and only in presence of potassium hydroxide. Acetone mid nitromethane do not react even in presence of potassium hydroxide. NitroisopropyZic alcohol is a colourless, limpid, almost odourless liquid, with a very peciiliar disagreeable taste. I n a mixture of solid carbonic anhydride aud ether, it forms a transparent, amorphous mass which after a time becouies crystalline, and melts at about -20"; sp. gr. = 1.1910 at 18"; boiling point 112' under n pressnre of 30 mm. ; vapour density 3.58. The acetate, OAc*CHMe*CH2*NO2, is a colourless liquid, insoluble in water and boiling at about the same temperature as the alcohol itself; sp. gr. = 1.2670 at 15'. The chloride, CHD/IeC1*CHZ*NO2, obtained by the action of phosphorus pentachloride, is a colourless liquid which boils at 172' under ordinary pressure ; sp.gr.= 1.2361 at 15' ; vapour density 4.25. The ni t;ro-alcohol, like nitromethane, burns with a greenish-yellow flitme ; with excess of potash, its riitrolic derivative gives the red coloraiion characteristic of the group CHZ*NO2. Secondary nitrobutylic alcohol has similar properties. The product of the reaction between nitromethane and formalde- hyde isa crystalhe solid which melts at about L4Oo, aiid dissolves in water and most organic solvents, but is only slightly soluble in ether. It may be nitroethylic ether (NO2*CHZ*CH2),O. Having regaid to the differences of composition between HCHO, CH3*CH0, and COMe2, and their different behnviour with respect to nitromethane, i t would seem that the tendency of the latter t o form additive products is conditioned by the presence of hydrogen in union with carbon in tbe group CHO.Since all nitroparafhs in which hydrogen is united with the same carbon atom as the NO2 group are basic like nitromethane, it would follow that all deriva- tives of this class containing the group, *CH2*N02, or :CH*N02, should form additive products with aldehydes, but this conclusion has not yet been verified. The same power should also characterise nitro- alcohols which contain either of the groups specified, and as a matter of fact nitrosopropylic alcohol combines readily with form- aldehyde or acetaldehyde. The combining power, with respect to aldehydes, of nitromethane and hydrogen cyanide is as 3 t o 1.In nitromethane, as in ammonia, the reaction capacity diminishes in proportion to the displacement of the hydrogen atoms by alkyl radicles. There is some evidence that in the reaction of iiitromethane with aldehydes, more than one product is formed, and not a single pro- duct on1-j- as in the action between the aldehydes and hydrogen cyanide. Allylphosphoric acid. By J. CAVALIER (Compt. rend., 1895, 121, 69-71) .-Glacial phosphoric acid dissolves in allylic alcohol with C. H. B.ORGANIC CHEMISTRY. 639 developmetrt of heat, and, after beiiig kept at about 100" for some time, a small qnantitg- of allylphosphoric acid is formed. The best results are obtained by graduallj adding phosphoric anhydride to a well- cooled solution of allylic alcohol in its own volume of dry ether.After distilling off part of the ether and adding water, the liquid separates into two layers, the upper of which seems to contain triallylic phosphate, whilst the lower contains allylphovphoric acid, which is isolated by converting it into the barium salt and decomposing the latter with sulphuric acid. AZlylphosphoric aczd, C3H5*H2P04, is a syrupy, uncrystallisable, dibasic acid, which is neutral to methyl-oi.ange when mixed with one equivalent of alkali, and to phenolphthalein when mixed with two equivalents. Many of its metallic salts are described; all the noimal ztllglphosphates which are only slightly soluble in water dis- solve readily in dilute acids, and are converted into the hydrogen salts. Most of the salts crystallise readily. C.H. B. Conversion of d- and LLinalool and of Geraniol into Terpin Hydrate. By FERDINAND TIEMANN and R. SCHMIDT (Bey., 1895, 28, 2137-2140).-1f d- or I-linalool is shaken with 20 times its weight of 5 per cent. sulphuric acid for several days at the ordinary tempera- ture, it slowly dissolves, and ether extracts an almost theoretical quantity of inactive terpin hydrate (m. p. 11 7-118Oj from the solu- tion. Gerauiol, also, when treated in a similar manner, yields terpin hydrate, mixed, however, with a small quantity of some syrupy sub- stance. It is thought that these facts point to the constitution, OH*CMe,*[CH2]3*CMe(OH)*CHz*CH2*OH, for terpin hydrate. Pinene yields terpin hydrate even more readily when treat'ed with dilute acids, and if Tiemann's formula for pinene is correct, then terpin 1lydi.nte would probably be OH-C Hz*CHz*C H (CMe,*OH)*CH,*C H (OH) *CHzMe, or OH*CH,* C H2*CH ( CMe,*OH)*CH2*CH,.CHMe*OH.The authors consider that one of the last two formulae is the more probable, and that terpin, which is inactive, is an intermediate product in the conversion of linalool into terpin hydrate. In anycase it is thought that terpin hydrate is a saturated open chain compound. J. J. S. Volemite, a New Heptitol. By EMJL FISCHER (Bey., 1895, 28, 1973-1974) .-Bourquelot described (Bull. Soc. Nycolog. de France, v) under the name of rolemite, a substance which he obtained from the fungus Luctarius volenaus, and thought to be isomeric with mannitol. He has lately sent a specimen to the atutlior, who finds it to be in reality a heptitol, C,HI60,.I t begins to liquefy at 147O, and melts at 149-151O (corr. 151-153") ; its specific rotation [a]= = + 1-92 at 20°, and it, is oxidised by nitric acid, or by bromine and sodium car- bonate, to a sugar volernose, the yellow osuzone of which, No intermediate product of hydrolysis was isolated.640 ABSTRACTS OF CHEMICAL PAPERS. melts and decomposes at 196' when heated quickly. was not obtained crystalline. The sugar itself C. F. B. Ammonia Derivative of d-Glucose. By CORNELIUS A. LOBRY DP BKUYN (Rec. Trav. Chim., 1895, 14, 98-105) .-d- GZwosamine, CsH,,N05, the molecular weight of which was determined by the cryoscopic method, separates in calculus-like aggregates of small, white needles when a solution of d-glucose in methylic alcoholic ammonia is kept for some weeks.The yield is about 50 per cent. of the theoretical. The pure substance, after recrystallisation from rnethylic alcohol, melts at 127-128', at the same time decomposing. It is not an aldehyde-ammonia, as stated by Stone (this vol., i, 320), whose analytical results are erroneous, but an isomeride of chitosn- mine (glucosamine), isoglucosamine, and acrosamine ; its basic pro- perties, however, are feebler than those of the last, as it does not form an oxalate. The specific rotatory power in aqueous solution is [aID = +19*5'. (1-Glucosamine is slowly hydrolysed by water into its proximate constituents, and, when exposed to air, absorbs water and loses ammonia. JN. W. Discoloration and Coagulation of Milk by Heat. By PAUL CAZENEUVE and HADDON (Compt..rend., 1895, 120, 1272-1273)- Milk which has been heated at 130' for an hour coagulates, and becomes very acid; it contains formic acid, A solution of lactose ( 5 : 100) containing a small quantity of sodium carbonate or disoclium hydrogen phosphat'e also becomes yellow, and contains formic acid if heated for an hour at 130". Formic acid is likewise produced when fresh milk, or the alkaline solution of lactose, is boiled for some time under atmospheric pressure, or when the alkaline lactose solution is heated on a water bath. Case'in, on the other hand, when heated in sealed tubes at 130' with water containing sodium hydroxide or carbonate, or disodium hydrogen phosphate, undergoes no change. It follows that the discoloration and coagulation of milk by heat is due to the oxidation of the lactose in presence of the alkaline salts of the milk, one product of the oxidation being formic acid, which pre- cipitates the case'in, but the latter undergoes no change, except that it is coloured yellow by the products of the decomposition of the lactose.C. H. B. Origin of Unsaturated Compounds in Plants. By CHARLES F. CROSS, EDWARD J. BEVAN, and CLAUD SRIlTH (Ber., 1895, 28, 1940-1945) .-When barley straw was distilled with dilute sulphuric acid, furf uraldehyde and volatile acids, chiefly acetic acid, passed over. The water, as it distilled over, was replaced by means of an automatic arrangement ; under these circumstances, and with acid of from 10 to 20 per cent. strength, it was found that furfuraldehyde and acetic acid were formed at about the same rate, and are consequently pro- ducts of the same reaction.No such relation was apparent when the strength of the acid was 30 to 50 per cent. Various cellu- loses were treated in the same way, and were found to yield volatile acids in addition to varying quantities of furfuraldehyde ; in a11 these cases, however, formic acid formed by far the larger part of theORGANIC CHEMISTRY. 641 volatile acids. Since woody matter yields a considerable amount of acetic acid when hydro!ysed, whereas cellulose yields but little, it seems that the group CH:CH is present in the former, and this group may have been introduced in the process of lignification, possibly through condensation of an aldehyde group with an acetic acid residue.C. F. B. Action of Formaldehyde on Amines. By R. CAMBIER and ANDRB BROCHET (Bull. SOC. C'him., [3], 13, 332--418).-When form- aldehyde and aqueous ammonia are mixed at -20°, no hexamethylene- tetramine is formed, as the product remains liquid ; and on removing the excess of water by means of potassium carbonate, a viscous liquid is obtained, which is at once converted into the tetramine by heat, or by the addition of caustic soda. The viscous product probably con- tains formaldehyde ammonia, OH*CH,*KH,, as a small amount of a pyridine base is formed during its conversion into the tetramine. Hexamethylenetetramine can be sublimed unchanged under very low pressure, and is not affected by water or aqueous ammonia at 150°, but in presence of eormaldehyde it is hydrolysed by water at that temperature into methylamine and carbonic anhydride.It dissolves more easily in cold than in hot water, and forms several hydrates. The hexahydmte, CsH12N,,6H,0, forms very large, transparent, hexa- gonal prisms, and melts and decomposes at 13.5". The so-called nitrosopentamethylenetetramine, formed by the action of nitrous acid on hexamethyleiietetramine (DelBpine, this vol., i, 326 j, is identical with nitroso trimethylenetriamine. Hexamethylene tetramine and its salts are decomposed by acids quantitatirely into methy lamine and carbonic anhydride (compare Delhpine, Zoc. cit.) ; it is a monacid base, perhaps feebly diacid, as it forms both normal and acid salts with the inorganic acids. The sukpliates, 2C6H,2N4,H2S04, and CsH,,N4,H,SO,, are both acid to phenolphthalein, but the former is neutral to methyl-orange ; the latter is readily hydrolysed by water and alcohol into its proximate constituents, the formaldehyde in the latter case combining further with the alcohol to form ethylal.The nos.maZ hydyochZol-ide, CsHl2N4,HCl, is neutral to methyl-orange and acid to litmus and phenolphthalein ; but the acid hydrochtoride, C6HI2N4,2HCI, is acid to all three indicators ; as, however, it yields the platinochloride of the normal salt, it is a molecular compound. The normal and acid n i t ~ a t e s are similar. All the above salts decom- pose at their melting points. The &chromate, 2C6H,,N,,HzCr2O,, and tetrachromate, 2C6H,,N4,H2Cr4O,,, explode when struck or heated. Formaldehyde condenses with hydroxylamine hydrochloride in cold, aqueous solution to formaldoxime, CH,:NOH, or its polymeride, trioximidomethylene, (CH,:N-OH),, with liberation of an equivalent of hydrogen chloride ; when the solution is heated, however, the pro duct loses water, and hydrogen cyanide is disengaged.Formaldehyde condenses with methy lamine hydrochloride to form ~rimethyZt.rimeth?jZenetriamiize, C6H15N3, an oily liquid boiling at 166", the molecnla~* weight. of which was determined by the cryoscopic method. This amiiie is a tertiary base, whosc salts are extremely soluble. It combines veadily wit11 alkylic iodides to form crystalline642 ABSTRACTS OF CHEMICAL PAPERS. additive compounds, but i t does not form a nitroso-derivative, or condense with formaldehyde. The hydrochloride, obtained by passing dry hydrogen chloride into its benzene solution, is extremely delique- scent, and melts and decomposes a t 120’.A platimchloride was prepared. E’ormaldehyde condenses with ammoniuru chloride in a very com- plex manner. It is probable that trimethylenetriamine occurs as an intermediate product, togetther with its condensation products wit ti formaldehyde, and those of the aldehyde with methylamine and dimetb ylamine, but under certain conditions these products act further with formaldehyde to form carbonic anhydride, methylamine, and trimethylamine. The yields of the amiries are quantitative, the former or the latter being produced accordingly as the ammonium chloride or the formaldehyde is in excess. These reactions afford i ~ e w and extremely convenient methods of preparing the two amines.Formaldehyde reacts with ammonium carbonate t o form hexa- methylenetetraniine, and with ammonium cyanide to form methylene- smidoace t oni trile. The authors confirm v. Miller and Plochl’s formula, (NPh*cE,)~, for the condensation product of formaldehyde witch aniline. It is highly probable that the trimethylene bases are ring compounds related to the isocyanuric derivatives, and having constitutions such as NMe<CH:,NMe> CH *NMe CH,. The parent substance, trimetbylenetri- arnine, is thus 8 secondary base, forming nitroso-derivatives, and condensing with formaldehyde. The alkylic derivatives are tertiary bases, and therefore do not form nitroso- or condensation products, but, on the other hand, readily form alkylic iodides.Triphenyltriruethylenetriamine is readily oxidised by dilute potas- sium permanganate, 01- even by air, to phenyiic isocyanide, and is broken up by hydrogen cyanide, with formation of phenylamidoaceto- nitrile, NHPh*CH,*CN; similarly amidoacetoniti-ile, or its condensa- tion product with formaldehyde, is obtained from a, mixture of form- aldehyde and the latter substance.

Bp PHILIWF, BARHIER and LOUIS BOUVEAUIX (Compt. ?.end., 1895, 120, 1269- 1272) .--The condensation with acetone, already observed i n the case of isovaleraldehyde (Abstr., 1894, i, 224), i s a general reaction for the saturated aldehydes of the acetic series, with the exception of form- aldehyde and acetaldehyde, which act in a more energetic manner and yield different products.Propaldehyde and acetone in presence of water and sodium hydr- oxide react with development of heat, and yield propyZideneacetolzP, CHEt:CH*CONe, :: liquid which obstinately retains water. I t s oxime is a colourless, viscous liquid, which boils at 85' under a pressure of 6 mm.; its acetate boiis a t 114' under a pressure of 9 iiim., and its sp. gr. = 1-0005 at 0'. Isobutylideneacetoize boils a t 153-155' ; its oxime is a colourless, oily liquid. which boils at 100' under R pres- sure of G mm., and its sp.gr. = 0.9322 at 0'. The acetate of the oxime is an oily liquid which has a disagreeable odour, and boils a t 126" under a pressure of 10 mm. ; sp. gr. = 0.9775 a t 0' The constitution of the non-saturated ketones thus obtained by condensation indicates the possibility of the occurrence of stereo- isomerism analogous to that existing betweeu maleic and fnmaric acids, but there is no evidence that the products described are mix- tures. They do not react with a mixture of aniline and hydrogen cyanide or ot' hydi-azine and hydrogen cyanide, nor with benzoyl- hydra zine. Isoamylideneacetooe (Zoc. cit.) condenses witli amidoguanidiiie (compare Baeyer, Abstr., 1894, i, 536), and the nitrate of the iso- ni,zyZidenencetoneamido~~~a~i~ine thus has the conatitut ion CHR/Ie2*CH2*CH:CH-CMe:N.C (NH)*NH,,HNOs.The corresponding picrate is insoluble in water, but can be crystal- lised froin boiling alcohol. Ohanthnldehyde and acetone, methyl prop91 ketone and propalde- liyde, and phenyl methyl ketone and deraldehyds do not react in a similar manner, from which it wouitl seem tliat acetone is the only ketone that condenses readily with aldehydes, and that the tendency to condense in the manner described diminishes as tbe molecular weight of the aldehyde increases, the condensation of the aldehjcte itself eventually becoming the dominant reaction. Condensation of Valeraldehyde. By CHARLES FRLEDEL ( C ~ n p t . remi., 1895, 120, 1394).-The author has obtained the a-isopropjl- ~-isobutylacraldehyde described by Barbier and Bouveeult (follow- ing abstract) by the condensation of valeraldehgde in presence of sodinm hydroxide.He regards it as identical with the compound of the same composition which has been obtained by several chemists in other ways, but considers that its properties are those of a ketone rather than of' an aldehyde. Condensation of Unsaturated Aldehydes with Acetone. By PHILIPPE BARBIER and LOUIS BOUVEAULT (Compt. rend.. 18Yi5, A. H. C. E. B. C. H. B.644 ABSTRACTS OF CHEMICAL PAPERS. 120, 1420-1423).-Methylethylacraldehyde when mixed with an equal weight of acetone and about 10 times its volume of water containing 0.5 per cent. of sodium hydroxide, and allowed to remain for about 24 hours, yields methy loetadienorhe. CHE t:CHMe*CH: CH* C OMe, a colourless, mobile liquid, which boils at 97" under a pressure of 8 mm., and has a feeble, aromatic odour; sp. gr.= 0.9170 at 0'. When boiled with its own weight of zinc chloride, it yields pseudo- cumene. a-Isopropy Z-P-isobut~ZacraZde~ yde, CHMe2*CH2*CH:C ( CHO)*CHMe2, is obtained by the condensation of isovaleraldehyde under the same conditions as lead to the production of methylethylacraldehyde. It is a colourless liquid, which boils at 73' under a pressure of 6 mm. ; its oxime is a colourless, oily liquid, boiling at 115' under a pressure of 8 mm. ; sp. gr. = 0.9147 at 0' ; the nitrile is a very mobile liquid, boiling a t 88-89' under a pressure of 8 mm.; sp. gr. = 0.8637 at 0'. When mixed with acetone in presence of dilute sodium hydroxide solution, i t yields the compound CHMe2*CH2*CH:C ( CHMe2)*CH:CH*COMe, which, according to the Geneva nomenclature, is 8-methyl-5-isopropyl- 3 : 5-nonadiene-%one.It is a colourless, somewhat viscous liquid, which boils at 123-125' under a pressure of 6 mm. When heated with zinc chloride. it yields metaisopropylcymene, which has an odour resembling that of cymsne, and boils at about 220' ; sp. gr. = 0.880 at 0". Some cymene is formed at the same time, most probably as a result of the partial decomposition of the isopropylcymene. C. H. 3. Action of Hydrogen Peroxide on Acetone and Mesityl oxide. By RICHARD WOLFFEXSTEIN (Ber., 1895, 28, 2265-2269).-Hydrogen peroxide in dilute solution (1 pel- cent.) has no action on acetone. With a 10 per cent. solution of the peroxide, a small quantity of a crystalline substance is obtained, which melts at 97', is insoluble in water, acids, and alkalis, but readily soluble in benzene, acetone, and ether ; i t slowly loses weight when left in the air, and more rapidly over sulphuric acid.The molecular weight, determined in benzene solution, agrees with the formula (C3H,0J3, thus indicating that the compound is a triinolecular acetone peroxide, with the constitution O*O*CMe2*? cMe2<0. 0 .C Me2. 0' An almost theoretical yiold of the substance may be obtained by mixing the acetone and hydrogen peroxide (50 per cent.) in mole- cular proportions, and then adding a drop of phosphoric acid. It is not acted on by acetic anhydride ; on warming with dilute sulphuric acid, it is decomposed into acetone and hydrogen peroxide; and is characterised by its explosiveness. When hydrogen peroxide (10 per cent.solution) is allowed to remain in contact with mesityl oxide for several months at theORGANlC CHEMISTRY. 645 ordinary temperature, a crystalline substance, (CsHl1O3)2, is obtained. It is quite neutral, melts without decomposition at 123O, and is insoluble in dilute acids and alkalis. The constitution is given as OH*CMe2*CAc (OH)*CAc( OH)*CMe2*OH. Synthesis of a Methylheptenone Methyl Butylideneethyl Ketone. By FERDIKAND TIEJ~ANN and PAUL KRUGER (Bey., 1895, 28, 211.5-2126) .-The authors have attempted to synthesise the iso- amylideneacetone which they have previously obtained by the oxida- tion of various members of the geraniol series, especially of germ- aldehyde (citral), CHILIe,*CH?.CH:CH*CMe:CH*CHO (Abstr., 1894, i, 83). Various attempts to condense isovaleraldhyde with acetone have shown that the chief product is the diisovaleraldehyde which is obtained by the condensation of two molecules of the valer- aldehyde.Small quantities of ot.her compounds were also formed, but they could uot be isolated in a pure form ; the fraction 160-180" probably contains the isoamjljdeneacetone, CHMe,*CH2*CH:CHCOMe, formed by the condensation of 1 mol. of isovaleraldehyde with 1 mol. of acetone. The authors show that the diisovaleraldehyde prepared by Barbier and Bouveault's method (preceding page) is identical with tbe diiso- valeraldehyde prepared by other methods (compare Friedel, this vol., i, 643, and L. Kohn, Cornpt.rend., 121, 259). When the ethylic isoamylideneacetoacetate of Claisen and Matthews (Annulen, 218, 174) is hydrolysed a t a low temperature with a 2.5 per cent. potassium hydroxide solution and the resulting ketonic acid heated, an oil which boils at 255-260' is obtained instead of isoamylideneacetone. This oil is probably a polymeraide of the desired ketone ; but in any case the reaction indicates that isoamyl- idenewetone is an extremely unstable substance, and in this respect differs from the natural methylheptenone. Under special conditions, isovaleraldehyde may be made to con- dense with acetylacetone to form the dikctone, which distils under atmospheric pressure at 218-220". It contains a hydrogen atom which can readily be displaced by metals. The copper derivative, Cu (C10H1602)2, is readily prepared by shaking an ethereal solution of the ketone with an aqueous solution of copper sulphate to which insufficient alkali for the complete precipitation of the copper has been added ; this copper salt is soluble in ether, and is obtained in a crystalline form when the ether is allowed to evaporate.The calcium derivative may be obtained by treating an ethereal solution of the ketone with dry calcium hydroxide, it is more sparingly soluble in ether than the copper compound. Methyl buty lid eneeth y l ketone, C HMe2*CH:CH* CHs.C OMe, is readily obtained when the copper derivative is mixed with an excess of calcium hydroxide in the form of a cream, and then submitted t.0 steam dis- tillation; it is an oily substance which boils at 163", and resembles J.J.

Its oxime distils at 122' under a pressure of 28 mm., and at 108-110' under a pressure af 15 mm. The semicarbazone melts at 115' after several recrystallisations, whereas the semicarbazone prepared from the nat4urnl product melts at 136-138'. The synthetical metliylheptone is also much more readily decomposed by acids and alkalis than the natural product. As the natural methylbeptenone can thus have neither of the follow- ing constitutions, CHMe2*CE2-C H:CH*COMe or C €€Me2*CH:CH*CH2-C OMe, i t follows tmhato i t must have the formula CMe,:CH*CH,*CH,*COMe (see following abstract).J. J. S. Natural Methylheptenone (Methyl Isopropylidenepropyl Ke- tone), Linalool, and Geraniol. By FERDINAND T~EMANN and FRIEDRJ CH W. SEMMTSR (Bey., 1895, 28, 2126-2137) .-From synthetical experi- ments. it has been shown (see preceding abstract) that the natural methylheptenone, which usually accompanies geranaldehyde, linalool, and geraniol in various ethereal oils, and which can readily be obtained by the gentle oxidation of one of these compounds, has the constitution CMe2:CH*CH2*CH2*COIe. The authors now show that the behnviour of the compound on oxidation supports this formula. The ketone ie oxidised in the cold with a very dilute permanganate solution, according ko Wagner's method (Abstr., 1890, 1313). By this means, the double bond is ruptured and two hydroxyl groups are added, thus forming a saturated glycol, which, in its turn, is oxidised by a mixture of chromic and sulphuric acids.The first product of the oxidation of the natural methylheptenone is a syrup, which, when further oxidised with chromic acid, yields acetone (characterised by its parabromophenylhydrasone, m. p. 94-95') and levulinic acid (cbaracterised by its phenylhydrazone). This decomposition of the ketone into levulinic acid and acetone agrees with the constitution of the ketone given above. The two aliphatic alcohols, geraniol, and linalool also yield con- siderable quantities of acetone and of levulinic acid when oxidised in a similar manner. The authors argue that linalool must therefore contain the grouping CMe2:CH*CH2*CH2*CMe:, and as it is an optically active alcohol must also contain an asymmetric carbon atom, giving the cons ti tu tion C H,*CMe: CH*C H2*C H2*CMe (0 H)*CH: C €I2. Geraniol, on the other hand, i8 an optically inactive primary alcohol, and hence has the formula CH,*CMe:CH*CH2*CH2*CMe:CH*CH2*OH.The authors consider that the alcohols, lavendol, nerolol, aurantiol, licareol, &c., are mostly mixtures of geraniol, and dextro- or laevo- linaiool, with small quantities of other alcohols, which give them their characteristic odours. Gemnaldehyde, which is the aldehyde corresponding with the primary alcohol geraniol, has the constitution C H,*CMe:CH*C H2*CH,*CMe:CH*CH0.ORGANIC CHEMISTRY. 647 A mixture of several isomeric compounds is obtained when the aldehyde is treated witlh semica.rbazide.The authors have isolated a carbazone which melts a t 130--135O, whereas Wallach gives the belting points of the geranaldehyde carbazones as 150' and 160". Geranaldehyde is readily converted into cymene by the action of potassium hydrogen sulphate, hydriodic acid, acetic acid, &c., the condensation being preceded by a displacement of ths double bonds. The authors criticise some of the conclusions drawn by Barbier and Bouveault (Abstr., 1894, i, 401) from the oxidation of geranaldehyde and its derivatives in strongly acid solution. They point out that qeranaldehyde derivatives are readily converted into terpin deriva- fives by the action of acids. a-Diketones. By LUDWIG CLAWEN (J. pr. Chenz., 1895, [2], 52, 76-77).-The author agrees with Fileti and Ponzio's conclusion (this vol., i, 499) that the isonitrosoketones, prepared by Manasse and himself from the ketones CH3*CO*CH2*R, have the constitution CH,*COC(NOH)*R, and not NOH:CK*CO*CH,*R, as he at first suggested.It is curious that amylic nitrite should attack the CH, group, for ethylic acetate attacks the CH, group, the compound CH2Ac*CO*CH2*R being formed. The Aldol of Diacetyl. By HANS v.

This is either 9-keto-11 : 12-oleic acid or 9-keto-12 : 13-ole'ic acid. Chloroketosteal-ic acid (m. p. 64O) yields the same unsaturated acid when similarly treated.When a boiling acetic acid solution of the chlorketostearic acid is treated with zinc and a littole hydro- chloric acid, it yields stearolic acid, CleH3202, thus losing the elements o€ water besides having hydrogen substituted for the chlorine. Ketostearic acid does not give stearolic acid under similar treatment. The following formula agree with the above reactione.648 ABSTRACTS OF OHEMICAL PAPERS.

Methenic and Methinic acids : Ethereal Cyanacetoace- tates. By ALBIN HALLER (Compt. rend., 1895,120, 119.3-1197).- The author proposes the term methenic acids to denote compounds which contain the group CE€,Rit', and ,methilaic acids to denote those which contain the group CHRR'R", all the radicles in both cases being electronegative. Compounds containing the group NHBR' might be called imidic acids.This classification into methenic and methinic acids is, however, based on a static view of their constitu- tion, whereas many of the compounds which contain these groups seem to be tautomeric. Briihl and Perkin regard the compounds CH,Ac*COOR and CO( CH2*COOR)2 as ethereal ketonic derivatives whilst acetylacetone and the ethereal salts of diacetylacetic and acetyl- malonic acids are regarded as unsaturated molecules in which the ketonic function is converted into an enolic functioii (Abstr., 1894, ii, 433).According to Claisen, the introduction of new negative radicles into the groups CH2 and CH, increases the tendency to become enolic, whilst the substitution of positive radicles has the opposite effect. When the ethereal salts of acetocyanacetic acid and its homo- logues (Abstr., 1888,81e) are brought into contact with phenylhydra- zine, they either combine with two molecular proportions of it, or yield acetylphenylhydrazine and its homologues, according to the temperature at which the action takes place. The first reaction can only be explained by assuming that the alkylic cyanacetoacetates have the constitution R*CH:C(OH)*CE(CN)*COOR, analogous to that attributed by Briihl to ethylic acetylmalonate, their acid functions being due to the presence of the group *CH(CN)*COOR and the enolic group.The compounds with phenylhydrazine will then have the constitution R* CHIC (OH) *C (CN) (CO OR) *N2H4Ph,N2H3P h. The second reaction, which takes place when the substances are heated, is represented by the equation NHPh*NH, + R*CH:C( OH)*CH( CN) GOOR - - - = NHPh*NHnCO*CH,R+ CH,(CN)COOR. The compounds with phenylhydrazine are readily obtained by direct combination in presence of ether, and considerable heat is developed by the action. They crystallise readily, bnt are some- what unstable, becoming yellow when exposed to light, and are decomposed by ordinary solvents. The compound with methylic cyanacetoacetate crystallises in plates which melt a t 87' ; with ethy lic cyanacetoacetate, white plates melting at 86' ; with ethylic cyanopi-0- pionylacetnte, plates which melt at 87' ; with ethylic cyanobutyrylacetate, plates which melt at 85" ; with ethylic cyanisobutyrylcccetate, slenderORGANIC OEEMISTRY.649 needles melting at 67". With ethylic cyanisovaleroacetate the product melts at 65', and with the methylic salt at 76.5". All these compounds, when heated, yield the corresponding homo- logue of acetSlphenylhydrazine.

GUINCHANT (Compt. rend., 1895, 120, 1220--1223).-For acetylacetone, by Kohlrausch's method, k = 0.00015 at 25'. Methylic and ethylic acetoacetates, methjlic malonate, and methylic cganace- tate, malononitrile, methylic acetylmalonate, and ethylic diacetoacetate show conductivities which are somewhat feeble, but tend to increase with time, especially in the case of the last two compounds, prob- ably owing to interaction with water. It is especially noteworthy that the only compounds which show any decided conductivity are those which are regarded by Briihl and by Perkin as containing the group C*OH, which is found in the carboxylic acids, phenols, normal cyanic acid, a-hydroxyquinoline, &c. Ethylic ricetoacetate and ethylic malonate, which contain the ketonic group, are practi- cally non-conductors.The sodium salts of the cyaaomethenic acids (preceding abstract), on the other hand, show a normal conductivity, and, like acetyl- acetone, obey Ostwald's law (k = const.) as closely as could be ex- pected, having regard to the fact that the compounds have both an acidic and an ethereal function. In those cases where the heats of neutralisation have been determined, the chemical activity de- duced from the thormochemical results agrees with that deduced from the conductivity. As a rule, in series of homologous acids, the value of k, and con- sequently the chemical activity, diminishes as the atomic weight increases. C. H. B. Preparation and Conductivity of Alkylic Cyanomethinates. By J. GUINCHANT (Compt. rend., 1895, 121, 71-73 ; compare pre- ceding abstract) .-The compounds described were prepared by Hal.ler's method of acting on an alkylic sodiocyanacetate with an acid chloride. Methylic cyanopropionylacetate forms crystals which melt at 39-40'; it boils at 130' under a pressure of 43 mm. Methylic cyanobutyrylacetate crystallises in needles melting at Oo, and boils at 135.5' under a pressure bf 25 mm.; the isobutyryl compound forms octahedral crystals melting at 36-37', and boils at 139' under a pressure of 48 mm. PropyZic cyanwetoacetate melts at 35-36' and boils at 153' under a pressure of 25 mm.; the isobutylic salt does not crystallive at - 15O, and boils at 142' under a pressure of 32 mm. ; the amylic salt does not crystallise at -15', and boils at 268' under a pressure of 46 mm.All these compounds give a red coloration with ferric chloride solution, and form insoluble cnpric salts; they displace acetic acid from its zinc and silver salts and form VOL.

The sodium salts crys- tallise as hydrates; the anhydrous salts a1.e more deliquescent the higher their atomic weights. The conductivity of solutions of these ethereal salts indicates that they are monobasic acids. The difference p 1024 -p 32 varies from 10 to 12; the value of p M is 351-352, and the value of k varies between 0.50 and 0.73. The conductivity decreases slowly with time, probably in conse- quence of the decomposition of the ethereal salt by water. The conductivity of the alkylic cyanomethenates diminishes as the mole- cular weight increases in the first three terms, but rises in the case of isobutylic cyanacetoacetate.Ostwald observed a similar change at the fourth term in the acids of the acetic series.

A mixture of I-idonic and I-gulonic acids is obtained, and these are separated by means of their brucine salts, which are solnble in 200 and 50 parts respectively of rnethylic alcohol, and melt and decompose at 180-185" (corr.185-190') and 155-158'.

By further reduction, it yields 1-iditol, which was obtained as a syrup ; a derivative of this, tribenzyzideneiditol, C,HsOs(CHPh), softens at 215', and melts at 219-223' (corr.224-228"), and dissolves in 105 parts of acetone ; tribeneylidenemannitol melts at 213-217O (corr. 218-222*), and dissolves in 34.5 parts of acetone. 1-Idosaccharic acid is obtained by the oxidation of I-idonic acid with nitric acid at 50" ; it is a syrup, and forms a copper saEt, C6HeOeCu + 2H20 ; the specific rotation is greater than -100'.

When warmed with water, it is rapidly converted into the acid, with alcohol, it gives the ethylic salt, and with dry ammonia, the amide (see above).The amide, when boiled with a mixture of sulphuric acid (1 part) and water (3 parts), yields the acid; whereas, when boiled with aqueous potash, it gives a substance which is isomeric with the amide; this melts at 150°, is readily soluble in alkalis, and is reconverted into the amide when heated at 160'.

By ~ T I E N N E BARRAL (BUZZ. 80c. Chirn., 1895, [3], 13, 418--423).-By the action of phosphorus pentachloride on a-hexachlorophenol or tetrachloroquinone, an octo- chloro-derivative of benzene is formed, whose constitution has an important bearing on that of quinone (compare this vol., i, 655).The hexachlorophenol(300 grams) is heated with phosphorus penta- chloride (215 grams) for 43 hours at 130-1135', or the tetracliloro- quinone (32 grams) with the chloride (52 grams) for three days at the same temperature, or, in presence of phosphorus trichloride, € 0 ~ half that time. The product, which solidifies on cooling, is washed with alkali and water and crystallised from benzene, the mixture of needles of hexachlorobenzene and prisms of the dichloride thus obtained being separated by hand. Hexachlorobenzene paradichloride, C6C1,, forms large, colourless, tri- clinic prisms or plates, sp. gr.= 2.0618 at l8", and melts, and to some extent snblimes, at 159-160'. It is insoluble in water, but dissolves in the usual organic solvents. By the action of heat (204') on the pure substance, or that of chlorine on its carbon tetrachloride solution in presence of antimonic chloride, it is resolved into hexa- chlorobenzene and chlorine. I t is not affected by chlorine in presence of sunlight or of iodine, but is reduced by sodium amalgam to hexa- chlorobenzene and hydrogen chloride, and is decomposed in a similar manner by proloiiged boiling with alcoholic potash, although it is stable towards aqueous potash. Hexachlorobenaene paradichloride is oxidised, completely by nitric acid, and partially by sulphuric acid, to t e trachloroqui none.The eape with which this octochlorobenzene is formed from, and converted into te trachloroquinone, leaves no doubt that its constitu- cci:cc1 tion is CC12<ccl:cc1>CC12~ PerLtachZoropheiaylic d i h yclrogen phosphate, CCI,O*PO (OH),,H,O, It forms occurs as a bye-product in both methods of preparation, colourless, transparent crystals, and melts at 224'.

The brzmhe compound, CsH3( N02)3rCa~H?6Nz04, forms slender, brownish-red needles, having a brilliant lustre, and me1 ts and decom- poses at 2 5 8 O , but no compounds could be obtained with strychnine, morphine, quinine, quinidine, or hjdrastine, a1 though colour changes were observed on mixing solutions of trinitrobenzene with daturine, carpaine, and code'ine. The indole compound, C6H3(N02)3,C,~,N, forms golden-yellow needles, and melts at 187" ; it is stable towards hydro- chloric acid, but is partially decomposed into its proximate consti- tuents by benzidine. The scatole compound appears to be of tbe same type; it forms slender, red needles, and melts at 183'.The pyryoline compound, CaH3(N02)3,CJNH0, forms long, very brilliant, yellow needles, and melts at 9S0, at the same time decomposing into its proximate constituents; it is very unstable, and readily loses gyrroline when dissolved in alcohol, or exposed to the air. No compounds could be formed with pyridine or quinoline, but a dark red, resinous product is formed when piperidine is heated with trinitrobenzene in alcoholic solution : the piperidine possibly acts as a reducing agent, as a similar action seems to take place with phenyl- hyd razine.

JN. w. Action of Sodium and Caustic Alkalis on Bolynitro-deriva- tives. By CORNELIUS A. LOURY DE BRUYN (Rec. Trav. Chim., 1895, 14, )39--94).-The peculiar colour changes brought about by the action of alkalis on di- and hi-nitrobenzoic acids can hardly be due, as V. Meyer supposes, to the formation of metallic substitution pro- ducts, for sodium has no action on trinitrobenzene, although this substance also yields a coloration when digested with alkali. The nucleal hydrogen of the di- and tri-nitrobenzenes and their homo- lopes is, in fact, not displaceable by sodinm, even when the hydro- gen is in the most favourable position, between two meta-nitro- groups ; any of the dinitrobenzen es, or symmetrical trinitrobenzene, or its toluene or xylene homologues, may be boiled with sodium in benzene or toluene solution for hours without undergoing any appre- ciable change.The colozcring n?atter formed by the action of alkalis on trinitro- benzene may be obtained in red crystals, having a green, metallic lustre, by adding cold, concentrated, aqueous potash t.0 a methylic alcohol solution of the nitro-compound. It is probably an additive compound, but is still under investigation. It is slowly decomposed by water into tetranitroazoxybenzene and potassium nitrite. The action of potash on trinitrobenzene is thus remarkably different from that of soda, by which the nitro-compound is decomposed into sodium nitrite and dinitroanisoil.JN.

Chim., 1895, 14, 95-97) .-The action of caustic soda on symmetrical trinitro- toluene and brinitro-xylene is much niore complex than that on tri- nitrobenzene, as instead of dinitroanisoils, brown, amorphous products are formed, soluble i n water, and reprecipitated by acids and metallic salts. They are probably azoxy-compounds, formed by reduction of the nitro-compounds . A eimilar product is formed by the act,ion of alcoholic potassium cyanide on metaclinitrobenzene, and is perhaps due to a similar cause, the entrance of the cyanogen radicle into the 1 : 2 : 3-ethoxycyano- nitrobenzene which is formed, resulting from the oxidation of the metal of the cyanide and the hydrogen of the nucleus by other mole- cules of the dinit,ro-compound.I n the case of dinitrotoluene, the amorphoua reduction product is alone formed. The introduction of a methyl group 018 groups into the nitrated ring has thus tho effect in both cases of favouring the more complex reaction. JN. W. 5-Chlorodihydrometaxylene. By A. KLAGES and EMIL KNOEVE- NAGEL (Ber., 1895, 28, 2044-2048 ; compare this vol., i, 86).--The action of cold dilute nitric acid converts chlorodihydrometaxylene into dimethyl-A,-ketotetrahydrobenzene ; if, however, 30 per cent. nitric acid is employed and heated with the substance for 24 hours in a reflux apparatus, nitrochlorometaxylene and symmetrical chlorotoluic acid are formed, a polyni tro-derivat.ive and chloropicrin being produced at the same time. Nitvochlol.ometnxyEene [Me2 : NO, : C1 = I : 3 : 4 : 5, or 1 : 3 : 2 : 51, forms colourless crystals, and melts at 48-49' ; it dissolves readily in organic solvents, is volatile in an atmosphere of steam, and distils without decomposing. Symmetrical chlorotoluic acid crysta.llises from dilute alcohol, and melts at 178' ; oxidation of the feebly alkaline solution with potas- sium permanganate converts it into symmetrical chlorisophthalic acid and hydroxyisoph th alic acid.When cblorodi hydrometaxylene is slowly dissolved in ice-col d fuming nitric acid, and then allowed to remain at the ordinary tem- perature, a vigorous action takes place ; equal parts of fuming nitric acid and 15 per cent. fuming sulphuric acid are then added to the liquid, which is boiled in a reflnx apparatus for half an hour.On cooliug the acid liqnid, syrnwtetrical tra'nitrochlovo?netazyleize sepamtes in lustrous, white leaflets ; it crystallises from alcohol in white needles, and melts at 218'. When heated with alcoholic ammonia at 130°, it yields symmetrical tvilzitrometaxyla'dine, which melts at 206' ; hhis base sublimes when carefully heated, and crystallises from dilute alcohol in yellowish-brown needles. Symmetrical trinitrop7~enylamidometa- lcylene is obtained by heating trinitrochlorometaxylene with aniline a t 150' ; it crystallises from alcohol in long, lustrous, yellow needles, and melts at 175'.

WIGNER (Bey., 1895, 28, 2027--S028) .-2 : 4 : 6-Trimethylethylbenzene, C6H,Me,Et, is best prepared by heating a mixture of 25 grams of bromomesitylene, 32 grams of ethylic iodide, 14 grams of sodium in thin shavings, and 25 C.C. of xylene at 180' in a paraffin bath. The reaction also takes place in ethereal solution at the ordinary tem- perature, but the yield is then very small. Ethyltrimethylbenzene is a fa.int aromatic-smelling liquid boiling at 212-214O ; it yields cry- stalline bromo- nitro- and sulpho-derivatives, which are being further examined.H. G. C. M. 0. F. Constitution of a-Hexachlorophenol and of Quinone. By ~ T I E K ' N E BARRAL (BUZZ. SOC. Chim., 1895, [3], 13,423-427).--a-Hexa- chlorophenol may be regarded either as a substituted ketone of the constitution CO<ccl~ccl>CClz or as a pentachlorophenol hypo- chlorite of the constitution c$&,*Oc1; but the former view is most in accord with facts. Hexachlorophenol is converted by phosphorus pentachloride into an octochlorobenzene (this vol., i, 652) and not into a hexachlorobenzene. A second hexachlorophenol is known, melting at 46", which can only be accounted for as a position isomeride, CCl'CC1 c c1 <CCl*C co~cclz>CC1. c1 Moreover, a hypochlorite would not be stable towards potash, and would not yield tetrachloroquinone on oxidation, as does a-hexachlorophenol.It is true that the hexachlorophenol does not form a bisulphite compound, but this may be explained by the lack of a common solvent for the chlorophenol and the sulphite. Similarly, the absence of a phenylhgdrazone may be explained by the fact that the chlorophenol does not contain hydrogem, and acts rather as a chlorinating agent towards the hydraaine. The conversion of a-hexachlorophenol into perchlorodioxydiphenylene and pentachloro phenol is explained equally well by either formula. ccI:ccl Since a-hexachlorophenol has the constitution CO<ccl:ccl> CC1, and its dichloro-derivative the constitution CCl~<ccl~ccl>CC12, the constitution of quinone can only be represented by Fittig's ketonic formula, CO< cHicH>CO.CH'CH The only serious argument against this formula, and in favour of Graebe's para-bond formula, was the formation of hexachlorobenzene instead of an octochlorobenaene by the action of phosphorus pentachloride on quinone, and this has now been shown to be due to the decomposition of the octochloro-compound owing to the use of an unnecessarily high temperature. Action of Zinc Chloride on Resorcinol. By EDOUARD GRIMAUX (Gompt. rend., 1895, 121, 88--100).-When resorcinol is heated for five or six hours at 135-145" with its own weight of zinc chloride, CCl'CC1 JN. W.656 ABSTRACTS OF CHEMICAL PAPERS about half of it is converted into resinous products mixed with small quantities of umbelliferone (hydroxycoumarin) melting at.255", and another compound melting at 261'. The umbelliferone can be isolated by ext>racting the product with successive small quantities of boiling water, arid the other product is obtained by treating the insoluble residue with boiling toluene. The compound which melts at 261" forms small colourless needles, insoluble i n water but soluble in most organic solvents. It is only slightly soluble in ammo&, but dissolves in potassium hydroxide solution, yielding a non-flaorescent liquid in both cases ; it gives no coloration with ferric chloride ; is decomposed when heated with zinc chloride or sulphuric a,cid, and the products show a green fluores- cence when dissolved in solutions of alkalis ; it yields no fluoresce'in with phthalic anhydride.It bas the composition C2iHl5O5, and seems to be formed from 4 mols. of resorcinol with elimination of 3H20, but i t is probable that part of the hydrogen eliminated is derived from the benzene nucleus. The resinous product insoluble in water and toluene dissolves in alkalis, and yields brown-red solutions with an intense green fluores- cence. It seems to be identical with the product obtained by Barth and Weidel by the action of hydrochloric acid on resorcinol at 180°, and erroneously described by them as resorcin ether. C. H. B. Derivatives of Elugenol. By CARL HELL (Bey., 1895, 28, 2082-2087) .--Dibromeugenol has the same phenolic character as eugenol itself, and readily yields derivatives, whilst dibromengenol dibromide cannot be converted into salts, ethers, &c.Dibromeugenol methyl ether, which was first described by Boyen (Bet-., 21, 1393), crystallises in white plates melting at 29.5'. It readily combines with bromine, forming dibromeugenoZ methyl ether dibromide, which crystallises in white, silvery plate8 melting at 65". Bromeugenol methyl ether dibromide, CBH2Br( OMe)2*C3H6Br2, is formed by the action of bromine on eugenol methyl ether, although a monobromo-compound cannot be prepared from eugenol itself. It crystallises in lustrous, white needles melting at 77". It is converted by zinc dust into bi*omeugeiaol methyl ether, which is a colourless oil boiling at 185' at 40 mm. pressure. It was found impossible to prepare a di bromo-derivative directly from eugenol methyl ether. Tribromeugenol dibromide is formed when the dibromo-compound is heated with bromine at loo", but4 has not been obtained in the pure state.The acetate crystallises in short needles or plates and melts at 137'. I'ribromeecgenol acetate is also a crystalline substance. Di- bromeugenol ethyl ethey is a light yellow oil, which solidifies in the cold to crystals melting at 20'. The acetate, prepared from dibromomethyl eugenol ether dibromide, is converted by oxidation with chromic acid into dibrmoveratric alde- hyde. The brominated ethers of eugenol are converted by alkaline per- manganate into brominated veratric acids, wbich have been made the subject of investigation.

By C-~RL Hmr, and B. PORTYANN (Ber., 1895, 28, 2088 - 2093).-Isoeugenol is converted by bromine into bronaisoezbgetrol tlibronzide, Oi$!!e-C6H2Br( OH)*C,H,Br,, which melts at 138-139'. If only 1 mol. of bromine be added very carefully to an ethereal solution of isoeugenol, it is possible to obtain isoeugenol dibroniide, which melts at about 86-87' but is exceedingly unstable. Isoeugenol therefore, in ils behaviour towards bromine, differs completely from eugenol, which is a t once converted into dibromeugenol dibromide. Isoeugenol methyl ether also readily combines with bromine to form the clibromide, which bas been described by Ciamician and Silber (hbsti-., 1890,966).The clibromide of the ethyl ether melts at 101-104'. The dibromides of the deriva- tives of isoeugenol are not attacked in alcoholic solution by zinc dust, whilst those of eugenol and its derivatives readily lose their bromine when treated in this way. The dibromide of isoeugenol ethyl ether readily reacts with sodium ethoxide to form a yellowish oil which boils at 177.5" (pressure = 16 mm.), and has the sp. gr. 1.039 a t 20'. This substance has the formula OMe*C6H3(OEt)*CH:CMe*OEt, and when exposed to the air or treated with dilute acids is couverted into a compound of the formula OMe*C,H,(OEt)*CH:CMe*OH, which crystallises in large tablets and melts at 56-57'. Methylisoeugenol dibromide, when treated in the same manner, yields an oil which boils at 192-193' (pressure r, 15 mm.), and is converted by dilute acids into large crjstals melting at 58-59'.This solid compound has the composition C6H,(OMe)2*CH:CMe.0H. Similar results have been obtained with the dibromides of anethoil and monobromanethojil, and will be subsequently described. These acids will be more fully described in a Derivatives of Isoeugenol. A. H. Preparation of the three Nitranilines. By E. BRUNS (Ber., 1895,28, 1954-1955) .-Aniline is dissolved in 6-8 times its weight of concentrated sulphuric acid, and the solution is kept cooled and stirred in an iron or nickel crucible while it is nitrated with the cal- culated quantity of nitric acid mixed with an equal volume of sul- phuric acid ; the temperature should not rise above 0'. The mixture is then poured on to ice and diluted with ice-cold water so long as 2-nitraniline is precipitated ; this is purified by one crystnllieation from alcohol.The filtrate is neutralised with powdered sodium carbonate ; if any resin separates at first, it is filtered off ; yellowish- brown 4-nitraniline is first precipitated, and then the 3-compound, which is pure yellow in colour. The colour change is so distinct that there is no difficulty in precipitating first the one compouDd, and then the other, after filtering off the first ; the precipitates are purified by one recrystallisation. I n t h i s way, aniline yields 10-15 per cent. of its weight of 2-nitraniline, and from 45-50 per cent. of each of the two isomerides. C. F. B. Aldoxime Salts. By HEINRICH GOLDSCHMTDT and LUDWIG R ~ D E R (Ber., 1895, 28, 2013-2020) .-The authors have examined the658 ABSTRACTS OF CHEMICAL PAPERS. lowering of the freezing point of solutions of the sodium salts of the following stereoisomeric aldoximes : syn- and anti-benzaldoxime, syn- and anti -paranisald oxi me, and syn- and anti-metani trobenzaldoxime, and, from the results obtained, it appears that, in aqueous solutions, the anti-salts undergo almost entirely electrolytic dissociation, whilst the syn-salts, in addition to the electrolytical dissociation, also show a considerable amount of hydrolytic dissociation. A further series of observations was made as to the alteration of the freezing point caused by the salts in strongly alkaline solutions, the syn-salts employed being those of benznldoxime, parmisaldoxime, metanitrobenzaldoxime, and propaldoxime, and the anti-salts those of para- and orthanisaldoxime, cuminaldoxime, and metanitrobenz- aldoxime.The anti-derivatives all behave in the same manner, the first addition causing a depression of the freezing point, but on further addition of the salt the freezing point rises and finally usually becomes higher than that of the original solution. Of the syn- aldoximes, the metanitrobenzaldoxime behaves in a similar manner, but' the others lower the freezing point in proportion to the amount of salt added. This Lehaviour of the syn-salts must be due to their hydrolytic dissociation, again showing that the sy n-aldoximes are much weaker acids than the anti-aldoximes. H. G. C. Derivatives of the Benzenediazocarboxylie acids.By ARTHUR HANTZSCH and 0. w. SCHULTZP (Be?.., 1895,28,2073--2082). -The derivatives of the benzenediazocarboxylic acids are obtained f porn the diazocyanides. The two stereoisomeric diazocyanides yield identical products, which appear t o belong t o the anti-series. Paranit~obenzenediazocarbamide, NO2*C6H4*N,*C O*NH2, is formed when nitrobenzenediazocyanide is boiled with water, and crystallises in long, ruby-red needles which melt at 183'; it may be recrystal- lised from hot water, but is only sparingly soluble in cold water. Parachlorobenzenediazocarbarnide is moderately soluble in cold water and crystallises in long, orange-coloured needles melting at 182". These amides can also be prepared by dissolving the diazocyanides in concentrated sulpharic acid, and by boiling the compounds of the diazocyanides with hydrocyanic acid, as well as the diazobenzene- carboxylic imido-ethers, with water.They are converted by alcoholic potash into the salts of the corresponding acids. Potassium parachlorobenzenediazocarboxylate, CsHaC1*Nz*COOK, forms lustrous, golden-yellow plates, It may be preserved in the dry state, bnt decomposes when moist and when its aqueous solution is heated. The salt deflagrates when heated or when placed in m1- phnric acid. The free acid is obtained as a yellow precipitate when a, solution of the salt is acidified with a mineral acid ; it decomposes very rapidly, chlorobenzene being among the products formed. Poiassium paranitrohenzenediazocarboxylate cry s tallises in brown needles. The free acid is slightly more stable than the chlorinated acid, but could not be analysed.The diazocyanides dissolve in alcohol with formation of the corre- sponding imido-ether of a, benzenediazocarboxylic acid. The ethyl- i f d o - e t h e r of nitroben~enediazocar~oxyl~~ acid,ORGANIC CHEMISTRY. 659 crystallises in orange-red needles melting at 73". The corresponding methyZiw,ido-ethey melts at 128-129". These compounds do not pro- duce any colouring matter with p-naphthol or R-salt. The methyl- imido-ether of chlorobeiazenediazocal.boxylic acid forms yellowish-brown needles melting at 69". Anti-nitrodinzobenzene cyanide reacts in a remarkable manner with p-naphthol, a yellowish-brown reduction product of the cyanide, which has the formula C7H5N402, being formed along with a compound of the formula C,,H7N02.ChZorodiazo7,enzeiaetoZyZguanidine, C 6H4Cl*N2* C (NH) *NH*C,H;, is formed by the direct union of chlorodiazobenzene cyanide with para- toluidine in alcoholic solution in presence of a few drops of aqueous soda, It forms reddish-brown crystals melting at 167". The hydro- chloride is a coloured, crystalline substance. The diazocyanides also unite with hydrogen chloride to form imidochlorides, which are exceedingly unstable. ChZorobenzenehydruzocarbamide, C,H4C1*NH*NH*CO*NH2, is obtained by the reduction of chlorobenzenediazocarbamide with alcoholic ammonium sulphide. I t forms white crystals, melts at 232", and reduces ammoniacal silver oxide. Chlorobenzeizeh?Jdrazotl~iocarbarnide, C6H,C1*NH*NH*CS*NH2, is obtained by passing hydrogen sulphide into an alcoholic solution of chlorobenzenediazocyanide and melts at 198".The compound of diazobenzene cyanide with hydrogen cyanide is converted by reduction into the imidocyanide of benzenehydrazo- carboxylic acid, which is identical with Fischer's dicyanophenyl hydrazine. A. H. Action of Diazo-compounds on Ethylic Cyanacetate. By B. MARQUARDT ( J . pr. Chem., 1895, [2], 52, 160-176; compare Abstr., 1894, i, 369) .-The salts previously described as labile forms of azocyanacetates (Abstr., 1894, i, 369) are probably correctly so described, whilst the stable forms are hydrazonecyan- acetates. The former can be converted into the latter by heating them above their melting points, or by heating them with alcohol. Ethylic metabyornophenylhydrazonecyanacetate, C6H4Br.*N2H:C (CN)*COOEt, is prepared by diazotising a solution of bromaniline in glacial acetic acid, adding ethylic cyanacetate, cooling in a freezing mixture, and adding crystalline sodium acetate.It forms yellow crystals, melts at 102", and dissolves freely in alcohol and ether, but only sparingly in benzene, chloroform, and light petroleum. By dissolving i t in alcoholic potash and adding hydrochloric acid to the solution, ethylic azobromobenzenecyanacetate, N,Ph*CH(CN)*COOEt, is precipitated ; this melts at 153O, and is converted into the phenylhydrazonecyan- acetate when heated with alcohol. The isomerides differ from each other in their solubility in benzene, the stable form (m. p. 102") being six times as soluble as the labile form. When ethylic metabromo- phenylhydrazonecyanacetate is heated with aqueous potash, it yields660 ABSTRACTS OF CHEMICAL PAPERS.bronzophenylhydrazoneacetic m i d , which melts at 167' and gives peci- pitntes with solutions of most metitllic salts. E t h y l ic d ib?*omophen ylh ydrazonecyanncetate, C6H,Brz.N2H:C(CN)*COOEt, is prepared in a similar manner from dibromaniline [NH, : Rr, = 1 : 2 : 51, but the yellow crystals obtained in this way melt at 160', and appear to be a mixture of the two isomerides, for when they are dissolved in potash, hydrochloric acid precipitates the labile form (ethylic asodibromobenzenecyanacetate), which melts at 172', whilst carbonic anhydride precipitates the stable form (the hydrazonecyan- acetate), which melts at 144'.One hundred parts of benzene dissolve 0.6943 part of the labile form and 0.1159 part of the stable form. Ethylic tribl.omop7tenylhycZrazonecyanacetate, C6HzBr3*NzH:C (CK)*COOEt, when prepared from tribromaniline (NH2 : Br, = 1 : 2 : 4 : 6 ) by the process described for the monobromo-derivative, crystallises in lustrous, golden laminq which melt at 144' and therefore contain a little of the labile isorneride. When these crystals are dissolved in potash, carbonic anhydride precipitates the hydrazonecyanacetate from the solution in crystals, which melt at 141' and dissolve to the extent of 5.103 parts in 100 parts of benzene at 15'. The labile form (ethylic n~otribro?~2obenze~~ecyanacetate) is precipitated from the potash solution by hydrochloric acid ; it melts at 134O, and dissolves to the extent of 8.858 parts in 100 parts of benzene.8 t h y lil: a-nap hthy lhy clrnzolaec yanacetate, C1,,H7* N2H: C( C N ) C 0 OF: t, is prepared fi-oiii a-naphthylamine by diazotisation and addition of ethylic cyanacetate ; i t forms yellow-brown crystals, melts at 147', and dissolves to the extent of 2-3482 parts i n 100 parts of benzene. When hydrolysod with alcoholic potash, it yields the corresponding acid, which forms dark yellow-brown crjstals and melts at 125'. Ethylic azo-a-naphthalenecyanacetate, prepared by precipitating the potash solution of the hydrazonecyanacetate with hydrochloric acid, forms brown-red crystals, melts at 105', and dissolves to the &ent of i3.5006 parts in 100 parts of berzene. JWy/lic P-iai~phthylhydrclz(~necynnacetate, as first prepared, melt's at 142', but when separated from the labile form by dissolution in potash and precipitation with carbouic anhydride, it melts at 1 4 5 O and dissolves in benzene t o the extent of 2.571 parts i n 100 parts.Hydrolysis with alcoholic potash converts it into the corresponding acid, which forms granular, yellow crystals and melts at 150'. E t h y l i c azo-t3-waphthaEenecymaacetate is precipitated from its potash solution by hydrochloric acid ; i t melts at 124' and dissolves in benzene to the extent of 5.137 parts in 100 parts. Neither iodine xn* sulphurous acid will change the labile form of ethylic tribromophenylhydrazonecyanncetate into the stable form ; but a small quantity of iodine will convert the labile form of ethylic sc-nnphthylhydrazonecyanacetate into the stable form.E't It y Zic metucarboxypheny ZlJ y drazonecy anacetate, COOH0C6H,*N2H:C (CN)*COOEt,ORGANIC CHEMISTRY. 661 was prepared by diazotising metamidobenzoic acid, adding etliglic cyanacetate, and salting out with sodium acetate ; it' forms crystals which inelf at 222'.

By HEIKRICH GOLDSCHMIDT (Bey., 1895, 28, 2020-2027).-The author has examined the depression of the freezing point in solutions of isodiazobenzene potassium and of diazobenzene sodium, a solution of the latter being obtained by the addition of diazobenxene chloride to a solution of soda of known strength and freezing point.The results obtained are analogous to those given by the salts of the syn- and anti-aldoxime salts (this vol., i, 657), and confirm Hantzsch's theory, that these diazo-deriva- fives are stereo-isomerides, similar to the aldoximes, but do not agree with Bamberger's supposition, that the former has the constitution NiNPh*OH, and the latter PhNX-ONa. In any case, the author regards the first formula as extremely improbable, as the radicle, PhgNiN, is a substituted ammonium derivative, and it, is extremely unlikely that its hydroxide would possess strcngly acid properties. In the latter portion of the papw, the author proposes a theory of the diazo-compounds which is identical with that just published by Hantzsch (this vol., i, 516), namely, that there are two structurally isomeric classes of diazo-compounds, the first containing the radicle, PhNX, and the second the true diazo-group, Ph*N:N*, and that the latter are, as Hantzvch has long maintained, capable of existing in two stereoisomeric forms.The reasoning on which these conclusions are based is practically identical with that of Hautzsch in the paper quoted.

It melts at 132', and when the solution, in water or alcohol, is heated alone or with acids, ammonium bromide and dibenzenylazoxime are formed. The hydrochloride is colour- less. When excess of bromine is employed in the preparation of the hydrobromide, the &bromide of this salt separates as a red powder, which melts atl 132' ; benzenylhydrazoximidobenzylidene is obtnined by treating it with ammonia, and hot alcohol converts it into dibenz- enylazoxime. Parahomobenzenylhydrazoximidoparabromobenzylidene hydyobrom- ide is a white, crystalline substance, and melts at 178'; it resembles the foregoing salt in behaviour, and when treated with bromine yields the dibromide, which is orange-yellow, and melts at 135O.Metanitroberizenylhydrazox~m~dometanitrobenzy1idene hydrobrom- ide is colourless, and melts at 158'; hot alcohol converts it into dimeta,nitrobenzeny lazoxime, which melts at 1.38'. The hydrobromide also yields the &bromide, which is yellow, and melts at 142'. Thiocar,.boizyldibenzenylamidoxime, CS( O*N:CPh*NH,),, is obtained by ad ding thiocarbonyl dichloride to a solution of benzenylamidoxime in benzene ; it melts at 96', and decomposes very readily in solution.

When heated at about 240°, the acid loses carbonic anhydride, forming metahydroxystilbene, OH*C6H,*CH:CHPh, which crystallises in long, thin needles melting at 280'.With sodium propionate, nieta bydroxybenzaldehyde yields the cor- responding metahydroxyphenylcrotonic acid, OH*CsH4.CH:CMe*COOH, which forms vitreous plates melting at 130' ; the silver salt, CloH,03Ag, is a thick, white precipitate, which beches pink, and finally black, on exposure to light, and the zinc salt, (CloH,03)2Zn, a white, flocculent pre- cipitate. When treated with sodiiim amalgam and water,'the acid is reduced to the corresponding metahydroxyphenylbutyric m i d , which crystallises in fascicular aggregates of spear-shaped needles melting at 63'. Attempts were made to brin,q about the condensation of meta- hydroxybenzaldehyde and succinic and malouic acids, but without success ; metethoxybenzaldehyde, however, also undergoes condensa- tion with the sodium salts of fatty acids, yielding analogous products to the hydroxy-derivative.The ethoxy-derivative may be obtained from the aldehyde, either by the action of potash and ethylic iodide, or by heating it with sodium ethylic sulphate and alkali; it is a yellowish oil, of aromatic odour, which boils at 245', and soon becomes brown. With sodium acetate and acetic anhydride, it yields ethylmetacournuric acid, OEt*CsH,*CH:CH.COO~~, which crystallises in matted needles and melts at 122'; with sodium propionate, it yields metethoxyphenylcrotonic acid, OEt*C6H4*CH:CMe.COOH, which forms long, spear-shaped crystals melting a t 80".

By CARL T. compare Abstr., 1894, i, 335 and 526) .- Cinnamic acid dichloride is usually prepared by passing chlorine into carbon bisulphide or carbon tetrachloride containing cinnamic acid in suspension, the operation being carried on in bright sunlight ; it melts at 167-168O.A different product is obtained, however, when the following con- ditions are observed. Cinnamic acid (60 grams), suspended in car- bon tetrachloride (750 grams), is submitted to the action of a current of chlorine (31 grams), the liquid being maintained at the tempera- ture of melting ice, and carefully protected from light; after remaining under these conditions for 8-10 days, solution is com- plete, and the liquid is transferred to vacuum desiccators provided with soda-lime and paraffin. The viscons oil thus obtained is con- An Isomeric Dichloride of Cinnamic acid.LYEBERMANN and H.

It is ver-y soluble in chloroform, carbon bisulphide, and carbon tetrachloride ; 100 parts of benzene dissolve 431 parts at, 21°, the same quantity of solvent being required by 2.3 parts of the ordinary dichloride at this temperature. The nzethylic salt is an oil which does not solidify when sown with crystals of methylic cinnn- mate dichloride (m. p. 100-101'). The isomeric cinnamic acid dichloride is dissolved by cold ammonia or soda, chlorocinnamene being formed when the liquid is heated; this decomposition is effected more readily than is the case with ordinary cinnamic acid dichloride, and an alkaline solution of potas- sium pormanganate is also attacked more rapidly, benzoic acid being produced.The removal of the halogeBfrom cinnamic acid dichloride and its isomeride, or from cinnamic dibromide and allocinnamic dibromide, results in the formation of cinnamic acid, whilst methylic cinnamate is obtained from their methylic salts, and from the methylic salt of the so-called allocinnamic acid dichloride. The following crystallographic information is included in the paper. Cinnamic acid dibrornide crystallises in colourless plates be- longing to the monosymmetric system ; a : b : c = 0.5472 : 1 : 0.4894 ; p = 88" 34.5'.Cinnamic acid dichloride (m. p. 167-168") belongs to the monoclinic system ; a : b : G = 0.3445 : 1 : 0.3485 ; p = 77" 59'. The isomeride forms rhombic crystals ; a : b : c = 0.8114 : 1 : 1.361L. The dibrornide of methylic cinnamate crystallises in monoclinic plates ; a : b : c = 0.91428 : 1 : 1.47985 ; p = 83" 1'. The dibromide of the ethylic salt is monosymmetric; a : b : c = 0.5541 : 1 : 0.8000; /3 = 88" 54'. The dichloride of methylic cinna,mate is isomorphous with the dibromide ; a : b : c = 0.88585 : 1 : 1.4278 ; /3 = 81" 23.5'. M. 0. F. Diazosulphanilic acid and its Stereoisomeric Salts. By ARTHUR HANTZSCH and D. GERILOWSKI (Ber., 1895,28, 2002-2012). -This paper contains a detailed account of the investigation of diazosulphanilic acid and its salts, some of the results of which have already been mentioned by Hantzsch, in his recent paper on diazonium compounds (this vol., i, 516).Diazosulphanilic acid has not the constitution usually assigned t o it, namely, but, like all other diazo-compounds which are stable in acid solution, is in reality a diazonium compound, having tbe constitution, and is the neutral anhydride of the diazoniunsulphonio acid. From the molecular weight in aqueous solution, it is shown that the above is the molecular formula. When diazosulphanilic acid is treatled with soda under certainORGANIC OHEMISTRY. 665 conditions of concentration and below Oo, it is converted into vC6Hi* S03Na , which forms white, N*O Na sodium szJndiazobenzenesul~~on~.te, silky needles, containing 4H20, 3+ mols.of which are evolved when i t is kept over sulphuric acid or phosphoric anhydride ; it rapidly reddens on exposure t o air, but is perfectly stable if kept over calcium chloride. Its aqueous solution has a strongly alkaline reaction ; it unites with alkaline &naphthol with great veadiness, and loses the whole of its nitrogen on warming in a current of carbonic anhydride. It also gives an intense yellow coloration with ammonia, and turns the skin orange, or dark red. When heated quickly with a small quantity of water, it is converted into the stereoisomeric sodium antidinzobeizzesze- ~C&'S03??a , already obtained by Bamberger, and ONa-N sulp hmat e, supposed by him at first to be a nitrosamine derivative; it forms nacreous plates, contains no water of crystallisation, only gives a slight coloration with @naphthol, and does not affect the skin.The conversion of the syn- into the anti-salt also takes place slowly at the ordinary temperature in aqueous solution, but the solid syn- salt may be kept man7 weeks in an exsiccator without alteration. The syn-potassium salt is obtained in the same manner as the sodium salt, and appears to be anhydrous, but gradually changes into the anti-salt, even in the solid state. Both the syn- and anti-salt lose nitrogen when boiled with water, the elimination being complete with the former, and nearly so with the latter. I n order to prove that these two salts are in reality both true diazo-compounds, the degree of dissociation and number of ions in their aqueous solutions was determined, and found to be three in both csses, whereas if either of the salts was a diazonium derivative, the number of ions must have been at least four.Both salts being therefoi-e diazo-compounds, they must be regarded as stereoiso- merides. An indirect proof of the intramolecular change which takes place in bhe formation of syndiazobenzene salts from diazosulphanilic acid is found in the action of alkalis on the latter. When slightly less than an equivalent of alkali is added to a solution of diazo- sulphanilic acid, at 0' and quite neutral, the reaction of the mixture becomes strongly alkaline, but after a time the solution gradually becomes neutral again, without any evolution of nitrogen. The first addition of alkali causes the formation of the salt still containing the free diazonium radicle, which has an alkaline reaction, but this gradually undergoes an intramolecular change into the diazo-group forming the neutral salt, ONa*N:N*C6H4*SO3Na.Conversely, if acid be added to the syn-diazo salt, ONa*N2*CsH4*S03Na, the solution becomes neutral as soon as it is completely converted into the salt, OH*N,*C6H4*SOBNa ; on the further addition of acid, the solut.ion assumes an acid reaction, but after a few minutes again becomes neutral, owing to the formation of the diazonium group, which is the only form capabie of existing for any length of time in acid solution.

Diphenacylacetic acid and its Reduction Products.By AUGUST PUSCH (Ber., 1895: 28, 2102-2106).-The acid obtained by Sattler (Abstr., 1893, i, 389) from chloralacetophenone by treatment wihh hot sodium carbonate solution is identical with the diphenacgl- acetic acid prepared by Rues and Paal (Ber., 19, 3147). On reduc- tion with sodium amalgain, this acid is converted into 3 : 4-dihvdroav- ., I CHz*C PkOH dipheny Ipentamethy lene-1 -carbozyZic acid, COOHCH < CH,. bPh,O 7 which crystallises in needles, and melts and decomposes at about 200°. This acid, which is insoluble in cold benzene, is accompanied by an isomeric acid, which is readily soluble in benzene, and melts a t 162-164'. This second acid is probably an allo-form of that first described. Each of these forms, when heat,ed with hydriodic acid and phosphorus, yields the same two isomeric 3 : 4-diphenylpentun?.ethyZene- carboxyZic acids.One of these crystallises in nodular aggregates, melting at 186-187', whilst the othey, which the author names the all,>-acid, is remarkably soluble in cold benzene, and melts at 150-152O. Three stereo-isomerides of the acid in question are possible, and the exact constitution of the two forms which have been obtained has not yet been ascertained. A. H.

By VICTOR KULISCH (Drlonafsh., 1895, 16, 351-357 ; compare Abstr., 1894, i, 552).--Renzoylbenzylide.lze- toluidine, C6H4Me*N:CPhBz, obtained on condensation of benzile with orthotoluidine, crystallises from ether in beautiful rhornbs [a : b : c = 0,45644 : 1 : 0.633581, is readily soluble in benzene, chloroform, and hot water, melts at 103-104', and is reconverted by acids into its generators. It yields an oairne, C21HlsN20, which crystallises in slender, white needles, dissolves readily in alcohol, and melts at 2 : 2'-H7~~roxyrnethylqz~inoZ~?ze, Cl,HgNO, obtained on condensation of orthotoluidine with ethylic pyruvate, crystallises from hot alcohol in slender, white needles, melts at. 203-205', has an aromatic odonr, and is only sparingly soluble in water.On distillation with zinc- dust, it yields a red oil, which boils at 239-255', has the odour of quinaldine, and gives a plstinochloride, ( CgNH6Me),,H,PtCI,, which melts at 226-230'. The bafie is therefore '1 : 2'-hydroxymethylquino- line, which forms a, platinochloride, melting a t 225-228", a szdphate, melting at 86-87", and a p'crate, melting at 95-96'. 178-NOo. G.

Chim., 1895, [3], 13, 427-430).-In reply to Prud’bomme (this vol., i, 423), the author reiterates the view he has held €or the past 15 yeare as to the constitution of the rosanilines, namely, that they all contain electropositive uni- valent radicles of the type, C(C6H4*NH&, in combination with chlorine, hydroxyl, $c., and that in the dyes tbemsel~es these radicles are combined wit.h such electronegative rndicles as chlorine, the corre- sponding carbinols being colourless. The iiitroduction of sulphonic groups into the phenyl radicles has practically no effect on their basic properties. These views are in reality confirmed by Prud‘homme’s results. Jr;. W. Constitution of the Rosanilines. By XUGUSTE ROSENSTIEHL (BUZZ. SOC. Chirn., 1895, [3 1, 13, 431-433) .-Prud‘homme’s view that the rosaniline carbonates are ammonium rather than ethereal mlts is incoiisistent with the adoption of the author’s formula, CCI(C,H,*NH,),, for the hydrochloride.The fact is that the char- acter of the triphenyvlcarbinol derivatives varies over a very wide range. Triphenylchloromethnne, for example, is hydrolysed by cold water, and thus resembles the acid chlorides in character, whereas triamidotriphenylcarbinol is more basic than ammonia. But tri- phenylcnrbinol forms alkylic ethers as stable as the mixed aliphatic ethers, and is thus still distinctly alcoholic in nature, although its basic character is not sufficientlv marked to allow of the for- mation of salt8s with acids ; triamidotriphenylcarbinol, on the other hand, forms both ethers with alkylic radicles, and etherzal salts with acid radicles. Thus even the most, acid in character of the rosaniline group is distinctly alcoholic, and Prud’homme’s carbonate must be regarded as a true ethereal salt. Corallin and Rosaniline.By CARL ZuLiiowsrir (Monatsh., 1895, l6,358--403).-Dyes and other organic compounds having a phenolic character may be conveniently purified by fiecipitating their a1 ka- line solulions with carbonic anhydride. The method answers well for aurin, roseol, and their derivatives, for pnenolphthaleh, and other similarly constituted substances. Coraliin, when prepared from pure phenol, contains two dyes in addition to nurin ; these have the formulae C20H1604 and C2,H1605(? j respectively, and do not appear to be closely related to each other.Corallin thus obtained also contains two substances which are isomeric but they exhibit no tinctoyial pro- perties; they contain 1 atom more of oxygen than aurin, have the formula C1SH,404, and may be regarded as a- and p-aurin oxide respectively. When corallin is prepared from phenol containing orthocresol, in additioii to the products mentioned above, the follow- ing series of compounds may be isolated : C24RzUO4, C22H1604, C20H1604, C20H1005 ; the first of these is roseol, t<he others have not previously been isolated. On diazotisirig rosani-line which is free from the para- compound, the substances C2jH,20~ jmetbylroseol) and CZsH,,O, may be obtained. u. T. 31. Jx. W.668 ABSTRACTS OF CHEMICAL PAPERS. Theory of Dyeing. Distribution of Methylene-Blue between Water and Mercerised Cellulose.By GEORG V. GEORGIEVICS and ERNST LOWY (i&mt572., 1895, 16,345-350).-1t has been previously shown (compare Georgievics, this vol., ii, 259) that the expression - . _ _ - -. , where x expresses the measure of the affinity of the dye for the fibre, is a constant for most, if not f o r all, substantive colours. The authors find that the same expression holds good in the distribntion of methylene-blue between water, and cellulose which has been tyented with caustic soda (mercerised cellulose), and that i t is independent of t,he stmctnre of the cellulose, which may be fibroiis, or in the pnlve~wlent form as obtained on adding an acid to a solution of cellulose in ammoniacal cuprous oxide. I t appears, moreover, that the quantity of dye taken up a t different temperatures depends on the sti-uctnre of the cellulose in a definite way, and that a far-reaching analogy exists between dyeing and other absorption phenomena.G.

With othei- proportions of aluminium chloride, phenyloxanthrnnol and anthraquinone are formed. It follows from the production of these compounds that, unless molecular transpositions are assumed to take place, the pht.halic tetrachloride me1 ting at 88" is unsymmetrical, and has the constitution CCl,*C,H,*COCl. Diphenylanthrone is also obtained by the condensation of benzene with phenyloxanthranol in presence of sulphuric acid, and is probably identical with the product, obtained by Baejer under these conditions, but uot described by him ; it is also formed by the action of benzene and aluminium chloride on pkeiu,jZoxar~thranoZ chloride.The latter is obtained by heating at 140-150' it mixture of diphenylphthalide and phosphorus pentachloride in molecular proportion, and crptallises 111 white prisms melting at 164' (uncorr.). Diphenylanthrone can also be obtained by the action of benzene and aluminium chloride on anthraquinone dichloride (dichloran th- rone).

Carvenone and isothujone are converted by yeduction into the alcohols tetraliydro- carveol and thujameiitliol, C,oB2,,0, and these, on oxidation, yield tetraliydrocarvone and thujamenthone.Thujone (fanacetone) is further converted at 280" into carvotan- acetone ; this already differs from isothujone, and when it is reduced to a tetrahydi-o-derivative (alcohol), and the latter is oxidised, a sub- stance is obtained which is identical with tetrahydrocawone, and different from thujamenthone. Thujone is thus converted by beat into a different isomeride from that into which dilute sulphnric acid transforms it. C. F. B. Alcohols derived from a Dextro-rotatory Terpene, Eucalyp- tene. By G USTAVE BOUCB-~RDAT and TARDY (Compt. vend., 1895, 120, 141 7-1 420).-EucaJyp ten e, the dex t r ogy rat e t erpene of eucalyptus, has a specific rotatory power of [a]D = + 39 a t 15' ; in boiling point (156-157") acd sp. gr.(0.870 at 0" and 0.865 at 18"), it is identical with the laevogyrate terpene from the pine oil of Landes. When heated with glacial formic acid, it yields a terpilenol, C2oH1802, which has a peculiar odour of lilac, crystallises from ether in bulky crystals melting a t 33-44', boils and decomposes at about 218O, and other- wise resembles the terpilenol from the laevogyrate terpene, but its specific rotatory power [a]D = + 8 8 O . When heated with benzoic acid a t 150", eucalyptene yields a674 ABSTRACTS OF CHEMICAL PAPERS. borneol which melts and boils at about 213". Its rotatorg power [aJD = +18" 40', whilst that of the corresponding camphor is +3l0, and hence the ratio between the two is abnormal, and indicates the pre- sence of the isomeride with reversible rotatory power described by Montgolfier.In fact, k y repeated conversion into the benzoate, the specific rotatory power of the borneol can be raised to +25O 50', whilst that of the camphor formed from it remains constant at +3l0. The camphor, when oxidised with nitric acid, yields a mixture of ordinary camphoric acid, which is somewhat solublz in water, melts at 181°, and has a specific rotatory power of +44", and racemocam- phoric acid which is only slightly soluble in water, melts at 203--204O, and yields an anhydride which melts at 2.33". The borneol seems consequently to be a mixture of dextrogyrxte borneol with some normal laxgyrate borneol and the lmvogyrate borneol of Montgolfier, with variable rotatory power. The isoborneol or fenchol, C10H1402, obtained at the same time as the borneol melts at abuut 45O, boils at 198-200°, and has all the properties of the isoborneol from the lsvogyrate terpene, except that its specific rotatory power is -10" to -10" 20'.The corre- sponding. camphor is strongly dextrogyrate, liquid at 15O, and solid at Oo, and seems to be identical with the anisic camphor of Landolph or the fenchone of Wallach. The inactive encalyptene seems to be a true racemic hydrocarbon ; it yields racemic borneol, inactive camphor, racemic camphoi-ic acid melting at 203-204", and the racemic camyhoric anhydride melting at 323'. It also yields an inactive isoborneol, a liquid racemic cam- phor, and an inactive terpinol, which seems to be identical with the terpinol from terpin. C. H. B.

Isohydroxycaniphor, CH -CH2--- C-OH, is probably formed in traces wheii the lactone is heated under reddced pressure, but only the lactone could be obtained by the interaction of isoamiclocaniphor hydroehloi-ide and sodium nitrite.

It is the stiidy of these reactions that has led the author to revise his previous views on the position of the ethylene linking in the a- and 13-campholene derivatives (see above). p-Cam- pholenic acid, when oxidised wikli dilute solution of potassium per- manganate, yields 6-dihydrox qd ihydrocamp hol enic acid, which is optically inactive, and melts at 146', and an acid which probably has the formula COOH*C:Hz*CH<Cw .kKMe ; it boils 40-50' lowey 1 ez t hail piuonic acid, with which it is isomeric. /I-Dihydroxydihydrocam- pholenic acid, when oxidised with chromic acid, is converted into oxalic acid, and acetyldi~zet72ylb2ctyric acid, C OMe*CMe ,*C Hz*CH2*C 0 OH, wliich is crystalline, melts at 48-49', and by the action of aIkaline bromine solution yields dimcthylglutaric acid (m.p. 85') ; this, when oxidised with nitric acid, gives unsymmetrical dimethylsuc- cinic acid. %ha1 and Blaise's recent investigation of the riitrosocampholene derivatives (Compt. rend., 121, 258) is discussed. According to the author's view, nitrosocamp boleiiic acid (m. p. 134.5') and nitroso- dihydrocampholenolactiine hare the formulae CO -C Hz ,CH2-- COO C OOHC H2GH < CH: YH and CH - -CH2---1CH C!

By ALUIN HALLER (Compt. rend., 1895, 121, S5-.38).-When a solution of benzylidenecamphor in glacial acetic acid is heated at, 100' with fuming nitric acid, it yields a compound, C1,H,8N205, which crysta.llises in white plates melting at 183'>, only slightly soluble in hot alcohol, and soluble i u boiling benzene.It is not affected by sodium carbonate solution, and when reduced with tin and hydrochioric acid, it yields the original benzylidenecamphor. It seems to be analogous to the compound obtained by Guthrie from aniylene (AnnuZen, 116, 284, and 119, 81), or to those obtained bv Gabriel from benzylidenephthalide (Abstr:, 1 885, 902), and probabG has the constitution C,H,,< I .

Benzylcamphor does not jield a nitro-derivative when heated with fuming nitric acid in presence of glacial acetic acid, but prolonged action of hot nitric acid converts it into caiiiphoric and paranitroben- zoic acids. with small quantities of other acids. When oxidised mith potassium pel-manganate, it yields camphoric and benzoic acids. C. H. E. Oxidation of Camphoric acid. By FWEDRICH MAHLA and FK~WINAND TIEMANN (Her., 1895, 28, 2151-2165 ; compare this vol., i, 4%).-The aut8hors mention the work of Wreden (Annulen, 163, 1:33), Roser (Abstr., 1886, 249), Bdbiano (Abstr, 1894, i, 614), Hlasiwetz and Grabowski ( A m a h , , 145, 212), Kachler (dbstr., 1874, 154), Koenigs (Abstr., 1894, i, 46), and Bredt (Abstr., 1894, i, 141 and 613).It is shown that! when d-cnmphoric acid is fused with 7; times its weight of potassium hydroxide for 20-40 miniites at a, temperature above 400°, the main products are acet8ic, isobutyric, pimelic (isopi-opylsuccinic), d-cis- and d-cistrans-camphoric acids. The authors have succeeded in separating each of these acids, and consider that the hydroxycarnphoric acid of Hlasiwetz and Grabowski is merely a mixture of the pimelic and tlie cis- and citrans-csmphoric acids. Experiments have been made by treating, with chromic acid mix- ture, mixtures of propionic and hy droxyisobutyric acids, and of lactic and isobuhyric acids, as well as mixtures of their ethereal salts, in order to dett imine whether trimethylsuccinic acid could be synthesised iindei- such conditions. As their experiments gave negative results, the authors conclude that the trimethylsuccinic acid, obtained by Bredt on oxidising camphoric acid with chromic acid mixture, is ~tORGANIC CHEMISTRY.679 simple oxidation product of the camphoric acid molecule, and is not the result of a condensation of several simpler oxidation prodn cts. They therefore agree with Bredt that, the molecules of camphoronic acid, camphoric acid and camphor must contain the grouping C.CMe2*C HMe-C. The authors also confirm Balbiano's observations on the oxidation of camphoric acid with potassium permanganate (Abstr., 1894, i, 614, and this vol., i, 552).They xaegard the acid, C8H1205, which melts at 12OC, as a ketonic dicarboxylic acid of the constitiition COOH-CHMe*CI\ilez*CO.COOH, and not as a hydroxydicarboxylic acid. It yields an oxiwze and a brornophenylhydrasone, the latter melting at 161-162'. When heated at 170-220°, the acid loses water and carbonic oxide, and is converted into trimethy lsuccinic anhydride ; when rediiced with hydriodic acid and phosphorous, it yields ibe acids C8H,,04 and CsH,,O,, which the authors represent as CHJle<Co~>CH*COOH and C 0 OH*CHMeGMe2*C H2*C 0 0 H respectively . The acid C8Hl4O4, when further oxidised, yields unsymmetyicai dimethylsuccinic acid. The acetyl, CHMe<~~~>C(OAc)*COOH, and benzoyl deriva- tives of the acid melting ah 120°, have been previously described by Balbiano.Camphoronic acid isrepreaentedas COOH-CHhle*CMe,*C H(COOH),, md the authors think that this formula, readily accounts for the decomposition of the acid into carbon, carbonic anhydride, trimethyl- succinic acid, and isobutyric acid (compare Bredt, Zoc. (it.). It is thought that all these facts point to the formula recently suggested by Tiemann (this vol., i, 428) for camphor and camphoric acid. Corresponding formuh for camphanic acid, campholactoiie, and lauronolic acid are also given. CMe J. J. S. Action of Phenylic Isocyanate on Campholic, Campho- carboxylic, and Phthalic acids. By AT,BIX BALLER (Compt. rend., 1895,120, 1326--1329).--Campholic acid, when heated with pheiiylic: isocyanate at a temperature not exceeding looo, yields campholic anhydride identical with that obt,ained by Guerbet by the action of acetic anhydride, but at 150-160° the products are (together with carbonic anhydride) aniline and campholanilide, which melts a t 90-91'.Attempts to obtain from campholic acid a phenylurethane analogous to that, of benaoyn were unsuccessful. It follows that, in its reactions with phenylic isocyanate, campholic acid resembles monocarboxylic acids siich as benzoic and toluic acids. Camphocarboxylic acid, when heated with phenylic isocyanate at 150-1 70°, yields the dianilide, C,H14( CO-NHPh),, which crystallises from chloroform in white needles melting at 228-223O, and froin boiling alcohol in elongated, bevelled lamell=; it is only slightly soluble in cold alcohol, and insoluble in light petroleum.

Isophthalic acid heated with phenglic isocyanate at 150-160' yields isophthalic dianilide, which crysta,llises from acetic acid in white needles melting a t about 250", but is insoluble in most other solvents. Terephthalic acid does not react with the isocyanate even at 210'. C. H. B. Vesicating Constituent of Croton Oil. By WYNDHAM R. DUNSTAN and LUCY E. boor,^ (Proc. Roy. Soc., 1895, 58, 238-240). -The authors have examined the vesicatiiig preparation known as crotonoleic acid prepared from croton oil by the method directed by Robert and Hirscheydt.The lead salt was submitted to a process of fractional precipitation by adding successive quantities of water to its soliition in alcohol ; by this meaus crotonole'ic acid was proved to be a mixture of inactive oily acids, the lead salts of which are precipitated first, and the true vesicating coiistituent ; the latter, or its lead salt, is principally contained in the last fractions, and repre- sents only n small proportion of the original material. On saponifying that part of croton oil which is soluble in strong alcohol with a mixture of lead oxide and water and fractionating an alcoholic solution of the lead salts with watey, the later fractions, which possessed the greatest vesicating power, furnished a resinous substance harving extraordinary power as a vesicant.The authors propose to call it (' croton-yesin." I t has the composition CI3Hl8O4, cannot be obtained crystalline, and does not yield any crystalline derivatives. I t is a hard, pale yellow, brittle resin, nearly insoluble in water, light petroleom, and benzene, but easily soluble in alcohol, ether, and chloroform ; when heated, it gradually softens, and is liquid at 90'. It has neither basic nor acid properties, and can be boiled with a mixture of lead oxide and water without any appreciable decomposition. It is gradually decomposed by boiling with aqueous potash and soda, and loses its vesicating power, several acids being formed, some of which are members of the acetic series. When oxidised with nitric acid, a mixtiire of acids is obtained.Since it is not saponified.by lead oxide and water, and as no glycerol could be detected among the products of its decomposition by alkalis, it is not a glyceride, and a s it does not react with hydroxylamine or phenylhydrazine 01- sodium hydrogen sulphite, it is probably neither a ketone nor an aldehyde. The authors hold the view that the con- stitution is that of a, lactoiie or anhydride of complicated structure. E. C. R. Poisonous Constituents of I' ananthe crocata" and of Cicuta virosa."

'Chis base, which probably has the constitution C5NHlo-CH:C:C:CH*C5NHI0, is prepared by heating iodothiophen (12 grams) with piperidine (10.5 grams) for six hours at 200" in a sealed tube ; it is a viscous oil, which gradually becomes darker and less mobile on exposure to air. When reduced by adding sodium to the solution in absolute alcohol, it yields tetranzethylerie- tZipipe,irZicZr, C,NHIo*[ CH2]&NHlo, a colourless oil which has the odour of coniine, and boils at 290--300° (uncorr.) ; tfhe platinochloride melts and decomposes a t 220".T,.i7lzeth~lZeiiedi~pe~~~ide, CjNHlo*C H2*CH2*CI12*C5NHI0, is prepared hy adcliug small quantities of tiimethylenic bromide to a boiling solution of piperkline in benzene ; it boils at 274-278' (uncorr.), and closely resembles the tetraniethylene derivative.

Dimethylumidoacetoize, NMe2*CH2*CONe, is prepared by adding chloracetone to an aqueous, 30 per cent. solution of dimethylamine ; it is a colourless oil, miscible in every proportion with water, alcohol, and ether, and becoming brown on exposure to air.T t boils at 123'. The hydrochloride is crystalline and very hygroscopic, and the platinn- chzoride, which forms beautiful crystals, melts and decomposes at 176' ; the azcrochEoride and methiodide melt at 145-146' and 168' respec- tively. The orime crystallises from benzene in needles, and melts at 99'; when the vapour is passed through a glowing tube an oily base is produced, probably it derivative of dihydroglyoxaline. The phewylhydrazone is an oil. Diethylamidoacetone, NEtyCH,*COMe, is a colourless oil which boils at 6 4 O under a pressure of 16 mm., and at 155-156' under atnio- spheric pressure ; it rapidly becomes brown on exposure to air, and is miscible with wa-tar, alcohol, and ether.Tho 1tyd.r.ochZoride is less hygroscopic than the salt of the foregoing derivative ; the platino- chEoride is crystalline, and melts at 176' ; whilst the aurochloride is an oil, and the methiodide is hygroscopic.

The hydrobromide melts at 108-1 14O and the aurochloride at 75-85". The base itself boils at 160-165'. Both copellidines may be separated in to their optically active isomerides by cry stallisation of the tartrates.The hvo-copellidine tartrate is more soluble than the dextro- compound, whereas the dextro-isocopellicline tartrate is more soluble t h a n the lnero-salt.

By boiling the hydroxyisoquinoline with ethylic iodide and alcoholic potash, ethoxyisoqzcinoline is obtained ; this, in tbe impure state, formed a thick, brown oil; its etlriodide melts a t 170", and when heated with silver chloride, yields the correspoiiding chloride, which melts at 63'.Anzidoisoquinoline yields a metlziodide which melts a t 228" ; the c h l o d e melts at 288O, the d r u t e at 203', and the sulphate at 230'. The ethobromide melts at 257O, the ethiodide a t 216', and the benzyloclzloride, with 2H20, a t 88" (218'). These all ci-ystallise in yellow needles. When the methiodide, either of hydroxy- or amido-isoquinoline is treated with silver oxide, a quaternary ani- monium hydroxide, insoluble in ether, is formed ; if, however, caustic potash be used, instead of silver oxide, a substance is obtained which is soluble in ether, but which must yet be a quaternary base, since it yields the same hydrochloride as does the base obtained with silver oxide.This behavionr is characteristic of the derivatives of quinoline, not of those of isoquinoline.

V. ROTHENBURG (J. pr.

When 3-phenylpyrazolone is suspended in water and treated with aqueous nitrous anhydride, a yellow or red isonitroso-derivative, C9H7N303, melting at 188' or 184', is formed ; the red silver salt of this decomposes at 242'. From this salt, ethyl, acetyll, and benzoyl derivatives may be prepared by replace- ment of the silver atom ; they are respectively red, yellow, and purple, and melt at 153", 82', and 142'. Alkaline reducing agents convert the isonitrGso-compound back again into 3-phenylpyrazolone ; acid reduc- ing agents, such as zinc dust and acetic acid, reduce it to 4-umido-3- yhenylpyrazoloiie ; this was not isolated, but its yellow benzylidene- arnido-derivative, melting at 152', was prepared by the action of benz- aldehyde, and it was oxidised by ferric chloride to a purple 3-phenyl- pyrazolonerutazonic acid, C,eB,3N,0z, decomposing a t 124'.The action NH*COORGANIC CHEMISTRY. 687 of the calculated quantity of acetic anhydride on 3-phenylpyrazolone in acetic acid solution converts it into a 1-acetyl deriwztice, which melts at 12.2' and yields a silzter salt. Excess of acetic anhydride brings about the formation of a diacetyl compound, which must, however, be a derivative of isopyrazolone, 1 : 2-diacet~Z-3-~henylisopyrazolone, ~Ac'cPh>CO ; this melts at 86', and forms no salts.3-Phenyl- pyrezolone also yields a yellow dibromo-derivative, melting at 189", and purple 4-axobenzene dericative, which melts at 207.5' and yields a yellow 1-acetyl derivative, melting at 199', and a, 1 : 2-benzylidene derivative, melting at 1.31'. 3-Phenylpyrazolone, when heated with methylic iodide and methylic alcohol, forms a 1-methyl derivative melting at 207" ; when treated in alkaline methyl alcoholic solution with rnethylic iodide, i t yields a small quantity of a 4-methyl deriva- tive, melting at 138'. 3-Phenylpyrazolone cannot be reduced in any simple manner ; excess of permanganate oxidises it to benzoic acid, but it is converted by the amount of permanganate theoretically neces- sary to oxidise it to benzoylformic acid into yellowish phenyZimido- acetic acid, NH:CPh*COOH, which melts at 59', and, when treated with phenylhydrazine acetate, yields the yellow phenylhjydrazone of henzqlforrnic acid, N2HPh*CPh*COOH, melting at 152'.Acid oxidis- iug agents, such as boiling solution of ferric chloride, convert 3-phenylpyrazolone into 3-phenylpyrazolone blue ; the two CH2 groups in two molecules being converted into the group C r C , and the two molecules thus joined together. 3-Methyl@yrazolone yields a, yellow 4-dibromo- and a purple h-azo- benzene derivative ; these melt respectively at 188' and 197". With methylic iodide and methylic alcohol, it yields 1 : 2 : 3-trimethy2isopyr- azolone; and, when treated with just enough permanganate to oxidise the methyl group to carboxyl, i t is oxidised to pyruvic acid, together with a little pyrazolone-3-carboxylic acid.3 : 4-Dirnethylpyrazolone is obtained by the action of hydrazine on ethylic methylacetoacetate, and melts a t 249'. It yields a reddish- grey 4-benzylidene derivative, the CHPh group replacing the two 4-hydrogen atoms in 2 mols. of the pyrazolone; also a 1 : 2-diacetyZ (iso), a 4-nitroso (?), and a 4-azobenzene derivative ; these melt at 12Y0, 44', 214O, and 188" respectively. It is oxidised by the amount of permanganate necessary to convert the two methyl groups iuto car- boxyl to a base melting art 225', the constitution of which was not ascer- tained. 3 : 4 : 4-Trimethylpyrazolone is obtained by the action of hydrazine on ethglic dimethylacetoacetate, and melts at 269".It yields but few derivatives, both hydrogen atoms oE the pyrazolone CH, group being now replaced by methyl. I t does, however, yield a 1-acetyl derivative, which melts at 168O, and it is oxidised by the amount of permanganate just necessary to convert the three methyl groups into carboxyl, to the same substance as was obtained in the oxidation of dimethyl- pyrazolone. Many of the experiments in the second paper have already been described (Abstr., 1894, i, 273, 344, 348, 384) .-3-Phenylpyrazole is obtained, together with much of the 5-isomeride, by the action of NAc-CO688 ABSTRACTS OF CHEMICAL PAPERS. hydrazine on benzoylaldebyde in alcoholic solntion ; i t melts at 228O. 3 : 4 : 5-Trimet7ylpyrazole is obtained b,y the action of hydrazine on methylacetylacetone ; it melts at 138-139' and boils at 234-236', and it is oxidised by alkaline permanganate to pyrasole-3 : 4 : 5-tri- carboxylic acid, which crystallises with 2H20, yields a crystallised potassium dihydrogen salt, and is converted into pyrazole when heated above 230'.5-J!tethyZp~/ruaoZine was obtained by the action of hydrazine on crotonnldehyde in alcoholic solution ; it i8 an oil boiling, with partial decomposition, at about 160'.

By OTTO KUHLING (Bey., 1895, 28, 1968-1971) .-The acid ob tained by the oxidation of toluallox- azine with potassium permanganate (Abstr., 1894, i, 624) loses car- bonic anhydride when heated at 190' with dilute hydrochloric acid (6-7 per cent.) ; the product dissdves in alkalis, and probably has a betaine structure (I), C OOH* $-N:v*NH- Q 0 gH*N:F*NH*Q 0 CH*N:C*COO *NHs CH*N:C*CO-NH I.Alloxazine. for it does not yield an acetic derivative, and evolves only traces of ammonia when boiled with strong aqueous alkalis. It melts at 284' with evolution of gas; at 250' it loses water, and the substance formed sublimes at 320°, yielding a yellow sublimate which is aZEox- w i n e ihself. This substance melts above 310' ; it hag acid properties, and i t is very stable towards acids and alkalis; when fused with caustic alkalis, it yields ammonia and hydrogen cyanide together with other products. C. F. B. Apoquinine and its Rotatory Power.By EDUARD LIPPMANN (Bey., 1895, 28, 1971--1972).-The author traverses Hesse's state- ments (Bey., 1895, 28,1301). To get pure apoquinine, it is necessary to use dilute hydriodic, in place of hydrocbloric, acid, and to precipi- tate the iodine with silver nitrate ; ether then extracts a base which crystallises in colourless prisms contaiuing ether OF crystallisation, which is lost only slowly at 110' ; the crystals have then become yellow, and have specific rotation [ a ] D = -217.1'. As to the formation of isomerides of quinine, this is probably one of the first stages of the reaction, but the whole subject is a difficult one. Two bases, melting respectively at 170-171' and 209-21l0, have already been obtained. C. F. B. Reduction of Cinchonine. By FR.KONEK v. NORWALL (Bw., 1895, 28, 1843--1844).-The author maintains the accuracy of t.he results obtained by him in his work on cinchonine (this vol., i, 521), which has been criticised by Hesse (this vol., i, 630). A. H. Cinchonicine. By FERDINAND ROQUES (Con%@. rend., 1895, 120, 1170-11 13).-Cinchonicine, obtained from the oxalate after theORGANIC CHEMISTRY. 689 latter has been carefully purified by repeated recrystallisation, will not crystallise from its ethereal solution in presence of air, but deposits more or less oily, amorphous products, a s described by previous observers. If, however, the ethereal solution is dried by means of potassium hydroxide, and evaporated in a current of hydro- gen at a comparatively low temperature, the alkaloid separates in crystals.The best results are obtained by evaporating first at about 25' or 30', and finally a t the ordinary temperature. Cinchonicine has the composition CI9H2,N,O, and its crystals are long, amber-yellow prisms with curved faces, belonging to the tri- clinic system. It melts at 49-50', alters rapidly when exposed to air, deliquescing to a syrupr liquid, and dissolves in .the ordinary solvents, but crystallises only from ether. Its rotatory power in a 1 per cent. alcoholic solution is [a], = + 48*25', and in presence of 2 mols. HC1, [a], = +25.72'. The base liberates ammonia from nminonium chloride, and is readily precipitated by picric acid. The double cinchonicine zinc chloride, C19H22N,0,2HC1,ZnC12 + 2H20, and the analogous cadmium compound, crystallise in colourless, transparent needles ; the methochloride in colourless, anhydrous needles, which melt at 159' (corr,), and the methiodide in yellow-, anhydrous crystals, which alter somewhat readily ; the etliobroniide is similar to the methochloride, whilst the ethiodide forms a fine, yellow, anhydrous powder, which alters somewhat readily.The hydrochloride and hydrobromide have not yet been isolated. The substance described a s cinchonicine by W. v. Miller and Rohcle (this vol., i, 434), does not seem to be identical with the cinchonicine isolated by the author. . C. H. B.

BAT- 'I'ANDIER (Con7pt. rend., 1895, 120, 1276--1277).-The crude alkaloids from Papaveraceze, such as BOCCO~Z'CL, Hypecoztm, EschscJLoltzia, and (lZazici?inz, give with sulphuric acid a reaction very similar to that of fumnrine.The root of Boccolnin fyutescens contains fumarine identical with that obtained from Fumaria ; another alkaloid, which the author calls bocconim, and which gives a peach- blossom colour with sulphuric acid; traces of a third, which gives reactions similar to those of chelidonine ; and a large quantity of chelerythrine. 1 Fumariiie, some time after it has been precipitated, becomes only slightly soluble in water and inost organic solvents, even a t their boiling .points, but is very soluble in chloroform. Its hydrochloride crystallises in heavy, transparent needles, With cold, concentrated sulphuric acid, fumarine gives a deep violet, almost blue, coloration, changing to brownish-black on the addition of potassium dichrornste ; traces of bocconine seem to modify this coloration. Bocconiize is relatively somewhat soluble in water and most neutral solvents, and crystallises in white, nacreous, silky tufts.The hydro- chloride crystallises in similar forms. With most reagents, it gives reactions very similar to those of fumarine, but its salts are more soluble, and the colour with sulphuric acid is characteristic. Cheleyythriize is present in somewhat high proportions in the bark of Bocconia, to which it gives its red colour. When boiled with con-690 ABSTRACTS OF CHEMICAL PAPERS. centrat,ed nitric acid, the deep red solutions of chelerythrine are decolorised, b u t on addirg excess of ammonia. the liquid becomes red. Eschscholtzizn califomica grows readily in Algeria, and the juice of the root is rich in chelerythrine.GZn?cciite.-Tke glaucine described by Probst contained small quantities of fumarine : when carefully purified it gives only a very faint, greenish-blue tint with concentrated sulphuric acid. On heating, however, the deep violet compound described by Probst is always obtained. The hydrobromide and hyclriodide are the oiily glaucine salts that crystnllise readily; the latter is less soluble in water t’han the former. c. H. n. Yellow Colouring Matter of the Urine. By ARCHTHALD E. GAI:ROD (Proc. Roy. Soc., 1894, 55, 394407).--E’or previous work compare Thudichnm ( B ~ i f . iltetl. Journ., 1864, 2, 509) and Schunck (Proc. Roy. Xoc., 1867, 16, 85). Uroblin, haematoporphyrin, and, occasionally, uroerythrin occur as pigments in urine, but the quantity of each is too small to account for the yellow coloration.The author has succeeded by the following process in extracting a new colouring matter. The concentrated urine is saturated with pure ammonium sulphate, filtered, and to the filtrate absolute alcohol is added ; this causes it to separate into two layers, the upper alcoholic layer containing the pigment. The latter, purified by a tedious pro- cess, the details OP which are given in the paper, is ultimately obtained as a brown, amorphous mass. The substance thus obtained is not quite pure, but usually contains a little urea mixed with it. It is very hygroscopic, and readily solubie in moter and in rectified spirit, but less so in absolute alcohol, and quite insoluble in ethei., benzene, or chloroform.The solution shows no absorption bands, does not fluoresce when zinc chloride and ammonia are added, and is readily decolorised by nascent hydrogen. The solution, when treated with nitric acid, gave the xanthoproteic reaction. Pre- cipitates containing the bulk of the pigment were obtained with lead acetate, mercuric acetate, silver nitrate, phosphotungstic acid, and phosphomoly bdic acid, but not with mercurous acet,ate. When a colourless solutiori of uric acid is added to a solution of the pig- ment and allowed to crystallise, yellow or brown crystals are obtained which are indistinguishable from those of natural urinary sediments. The author think8 that the products obtained by Thudichum, Tich- borne, and Schunck are p~obably the same as his, on11 in a more 01’ less impure state. J. J. S. Reduction of Alkaline Copper Solutions by Protei’ds. By EU~IVSU DRWHSEL (Zeit. physiot. Chem., 1895, 21, 68-i0). - Krukenberg stated that a t the boiling temperature there is in the so- called biuret reaction of protexds a reduction of the cupric to cuprous oxide, t,he latter, however, remaining in solution. The present research shows that this reduction also occurs at the ordinary temp- rature; i t is, however, very slow and incomplete. The solutions were kept for a year before they were examined. The substances used were Witte’s peptone, and deutero-albumose. This result doesORGANIC CHEMISTRY. 691 not necessarily meail that these substances contain a carbohydrate radicle, for many substances not carbohydrates reduce Fehling'e solution. W. T). H. Mode of Combination of Sulphur in Albumin. By F. SUTKI~ (Zeit. physiol. CLenz., 1895, 20, 564--582).-The following sub- stances were tested in order to ascertain to what extent the sulphur which they contain is precipitated when they are heated in alkaline solution with lead a,cetate. The precipitation from cystine, with or without peptone, and cysteine is incomplete, and proceeds very slowly, only 60 per cent. being obtained after 9.5 hours. Hair and feathers deposit 98.8 and 98 per cent. after 9 and 25 hours respectively ; egg a1 buniin and peptone behave in a similar manner ; these compounds therefore resemble cystine. The production of a clear filtyate is no criterion of complete precipitatiou. Under similar conditions the sulphur is completely precipitated from thiocarbamide and allylthio- carbamide. Attempts mere made to isolate cystine or cyste'ine from residues obtained during the preparation of tyrosine, but witlrout FUCCBSS ; these substances are not., therefore, direct decomposition products of horn, but they may posssbly be formed in traces. The above mother liquor contained a-thiopropionio acid in rather small quantity ; this was recognised by its benzyl derivative which crystal- lises in colourless prisms, melts at 73", and is identical with the synthetical compound obtained from benzylic mercaptan and et hylic a-bromopropionate. A second substance, which has strongly acidic properties, and contains sulphur, was also isolated from the tyrosine mother liquor ; i t gives a blue coloration with ferric chloride, and a fugitive violet with copper sulphate ; it does not yield a benzyl deri- rative, and is possibly thioglycollic acid (compare following abstract) , a-Thiopropionic acid is not tt primary decomposition product of albumin. By the action of hydrogen sulphide on pyruvic acid in aqueous solution, in presence of sodium acetate, a-thiopropionic acid is formed ; pyruvic acid is also not a primary decomposition product of albumin, as it is not present in the tyrosine mother liquor. Sulphur Derivatives of Albumins and their Interrelation- ship. By EUGEK BACMAXN (Zeit. physiol. Chem., 1895,20,583-565 ; compare preceding abstract) .-The formation of a-thiopropionic acid from cysteino resembles that of hydroxyparacoumaric acid from tyro- sine. It is very probable that the ethylic sulphide, which J. J. Abel found in dog's urine, particularly after a meat diet, is poduced by the decomposition of a-tliiopropionic acid. Nencki has shown that methylic mercaptan is formed during the decomposition of nlbumiii, and should Suter's observation of the occurrence of thioglycollic acid be confinned, these would appear to be related, like ethylic mercaptan and a-thiopropionic acid. The primary t hio-decomposition product of albumin is unknown ; possibly it. may prove to be a thioaspartic acid, NH,*C(SH) (COOH)*CHn*COOH. J. B. T. J. B. T. The Behaviour of Casein in Ammoniacal Magnesium Chloride Solution. By WACLAW v. MORACZEII-SKL (Zeit. physiol.692 ABSTRACTS OF CHEMICAL PAPERS. Chew., 1895, 21, 71--78).-A solution of casei'n free from ash (casei'no- gen), when mixed with ammoniacal magnesia mixture, proceeds, after some days, to deposit sphareoliths ; these, by attention to details, described in full in the paper, can be obtained in the form of aggre- ga,tions of needles. They contain 45 per cent. of ash, and 14.98 per cent. of nitrogen. The nature of this proteid compound of magnesium is, however still uncertain. Nuclejin a1 so yields a crystalline deposit with ammoniacal magnesia mixture. W. D. H. Precipitation of Toxalbumins by Nuclei'c acid. By 31. TICHONIROFF ( Z e i t . physz'ol. Chem., 1895, 21, 90-96) .-Rich is pre- cipitable by nucleic acid. The precipitate can be redissolved, and, when tested on animals, is found to be still as poisonous as before. The same WAS found to be true for tetanus poison and diphtheria poison. The addition of nucle'ic acid to solutions of cholera poison and to cultures of streptococci, Staphylococcus aureus, and typhoid bacilli (in all cases freed from the growth of micro-organisms) produced a precipitate, which, however, was not poisonous. From putrefying beef, the precipitate was also not active ; bnt a poisonous precipitate was obtained from putrefying fish. W. I). H. Amylase. By JEAN EFFROW (Conzpt. rend., 1895, 120, 1281- 1282) .-An infusion of barley prepared a t the ordinary temperature, boiled and filtered, greatly increases the diastatic power of malt, and thus resembles aluminum and vanadium salts, aspamgine, picric acid, Stc. (Abstr., 11393, i, 187). Since, however, in all cases the sacchari- fyiiig power only is increased, whilst the liquefying power is practically unaffected, and the effect disappears in presence of such quantities of amylase as are required to produce energetic saccharifi- cation, the increase in saccharifying powel. is more apparent thau real. A comparison between the saccharifying and liquefying powers of' millts yields better results than the methods of Kjeldahl and Lindner. The substance to be examined is extracted with eight times its weight of water. The saccharifying power i8 measured by the volume of the solution required to produce in an how, at 45'. 0.25 t o 3 grams of maltose per 100 C.C. of starch paste, the experiment being made with 15d C.C. of a 1 per cent. solution of starch. The liquefying power is expressed by the volume of the solution required to liquefy in 10 minutes, a t BOO, 20 C.C. of milk of starch containing 40 parts of starch in 100. The ratio between the saccharifying and liquefying powers in good malt is 100 to 120, but in presence of sub- stances that increase the saccharifying power it may rise to 200-400. The diastase of the crude barley shows a ratio of more than 1000. The saccharifying power being equal, the value of two malts is proportional to the ratios bc tween the saccharifying and liquefying powers. C. H. B.
