[Issued 15/6/12 PROCEEDINGS OF THE CHEMICAL SOCIETY. Vol. 28. No.403. Thursday, June 6th, 1912, at 5.30 p.m., Professor PERCYF. FEAXKLAND,LLD., F.E.S., President, in the Chair. The PRESIDENTreferred to the loss sustained by the Society in the death of M. Lecoq de Boisbaudran (elected an Honorary and Foreign Member in 1888) on May 28th. Messrs. G. F. Wesley Martin, R. Robinson, and C. R. Wilkiiis were formally admitted Fellows of the Society. Certificates were read for the first time in favour of Messrs. : James Harry Dyson, North Lea, St. Ives Road, Skircoat Green, Halifax. Sydney Charles Gadd, 31, St. David’s Hill, Exeter. Shigeru Komatsu, College of Science and Engineering, Kyoto Imperial University, Eyoto, Ja.pan. Ramni Paniker, &LA.,M.Sc., c/o Messrs.Rohni & Haas, 4, Quai St. Clair, Lyons, France. I-Iui Chun Tsao, B.Sc., I-Hing, Kiang-Su, China. Of the following papers, those marked * were read: “136. ‘(The vapour density of ammonium nitrite.” By Prafulla Chandra Rky, Nilratan Dhar, and Tincowry De. The vapour density of ammonium nitrite as determined by Hofmann’s method at a temperature of 66O to 75O conforms to the normal value. ”137. Pyrogenic decompositions. Part I. Benzene.” By Clarence Smith and William Lewcock. References to the literature show that a substance, produced by the pyrogenic deccmposition of an organic compound, is obtained usually in very poor yield; for example, the best yield of diphenyl obtained by the pyrogenic decomposition of benzene is 30 per cent., recorded by Schultz (Annalen, 1874, 174,201). In the course of some experiments by one of the authors on the formation of isoprene by the pyrogenic decomposition of American turpentine, the prime importance of temperature and of duration of heat,iiig on the course of the decomposition has becn made very manifest.The experience thus gained has been applied in the pyrogcziic: decornposi tion of benzene, with the result that a continuoi~sly-working apparatus has been constructed, whereby benzene is con- verted into diphenyl to the extent of 70 per cent. of the theoretical yield; solid by-products are formed only in traces. *l38. (( The absorption spectra of certain aromatic nitroarnines and nitroamides.” By Gilbert T.Norgan, Edgar Jobling, and Raymond T. F. Barnett. The authors have continued the spectroscopic examination of certain of the polynitrated aromatic amines (compare Trans., 1911, 99, 1945), and particularly of the dinitro-derivatives of this series. The absorption curve of 2 :6-dinitro-p-toluidine was found to be quite comparabie with that of the tsrtiary amine, 2 :G-dinitro-dimethyl-p-toluidine, both bases showing very considerable suppres- sion of the absorption band. On comparing the absorption spectra of 3 :5-dinitro-p-toluidine, 3 :5-dinitromethyl-p-toluidine, and 3 :5-dinitrodimethyl-ptoluidine, it was found that only the tertiary arnine showed this suppression, both the primary and secondary bases exhibiting a well-marked absorption band, that of the former base being the more persistent.5 : 6 -Dinitro-3-ainino-o-xy lene and 3 :5-dinitro-6-amino-o-xyleiic also show this suppression of the band characteristic of the majority of aromatic nitroamines, whereas 3 :5-dinitro-4-amino-o-xyleiie, 3 : 4 -dinitro-5-amino-o-xylene7 and 4 : 5 -dinitro-3-amino-o-xyleiie exhibit selective absorption of the normal type. Picramide shows two well-defined absorption bands. Toluene-p-sulphonyl-1-nitro-B-naphthylamine(yellow) and its M-methyl deriv- ative (colourless) and toluene-p-sulphonyl-1:6-dinitro-j3-naphthyl-amine (colourless) do not exhibit absorption bands, either in the visible or ultra-violet regions of the spectrum. 153 The aromatic riitroarnicles exhibit absorption spectra of tho Same geticral t,yp wi thut absorpt,ioii hilnds, whether the acyl groups ;I w inorganic (NO, NO,) or organic (CH,*CIO, S02*C7H7,etc.).+139. ‘ The constitution of harmine.” (Preliminary note.) By William Henry Perkin, jun:,and Robert Robinson. The authors have commenced a series of experiments on the alkaloids of pegnn7cm IbarrnaZa, and are now in ;I position t,o suggest an expression (I) which readily affords an ctxplanatioii of t,he reactions of I~ariiiirie, and cannot, be very far fro111 tJie true represent,:ttioii of the coiistit,ution of this substance : (11.) The complete argument on which this formula is based cannot lie given here, but, in addition to the facts which have already been observed by other workers, among whom 0.Fischer is the most prominent, the following new observations have greatly cori- tributed to the sclution of the problem. Harmine contains an NH-group and a methyl group, which has the power of condensing with aldehydes, etc., characteristic of the methyl group in quinaldine. Uenz yliden e hawninp, C,,HQON,*CH: CHPh, is obtained by boiling harmine with excess of benzaldehyde, and is purified by conversion into the sparingly soluble, bright yellow, crystalline hydrochloride. The base separates from ethyl alcohol in pale yellow prisms melting at 191--19Z0, and its solutions have a most intense violet fluorescence. p-i~-?;trobe.nzylidenel~ar.nLine, C1,€IQON,*CH:CH*C,H,*NO,, prepared by heating together harmine and p-nitrobenzaldehyde, separates from alcohol in red needles and melts at 266O.C-Bemylharmine, Cl,H,0N2~C€I,*CH,Ph, obtained by the reduc- tion of benzylideneharmine with zinc dust and acetic acid, crystal- lises from methyl alcohol in rectangular prisms melting at 138O. The sparingly soluble hydrocuoride separates from water in colourless needles which, in dilute solution, exhibit a blue fluores- cence. 154 Norr-~~armineca?.7,oxylicacid, C,2H,0N2*C0,TI:,obtained by the! oxidation of benzylideneharinine with potassium permanganate i II acid solution, crystallises from acetic acid in the form of the acetat’e in yellow prisms. This substance loses acetic acid on heating at looo, or better by treatment with hot water, and furnishes the free acid as a pale yellow, crystalline powder, which is almost insoluble and could not be, recrystallised.Its salts, both with acids and alkalis, are crystalline and sparingly soluble in water. With ferrous sulphate it. develops a brownish-red coloration, which again clearly indicates that the methyl group in harmine is in the a-position with respect to one of the nitrogen atoms. The formula of apoharmine (11) deduced from that suggested for harmine (I) is that of 2-methylindole, in which one of the methine groups of the benzene ring is displaced by a nitrogen atom. Such substances have not yet been prepared (see, however, the following note), and the properties of such a fused pyridine- pyrrole nucleus are unknown. There can, however, be little doubt that the pyridine ring would greatly modify that of the pyrrole ring, and the structure, CH /\/\I I CH,\/\/N NH may be regarded as an independent nucleus probably presenting closer analogy to benziminazole than to either quinoline o,r indole.A number of experiments are in progress, having for their object; the synthesis of substances containing the pyridine and pyrrole rings fused in various positions. “140. The synthesis of isoharman.” (Preliminary note.) By William Henry Perkin, jun., and Robert Robinson. An important stage in the argument developed in connexion with the constitution of harmine consists in deciding between the structures : CH 155 0. Fischer (Chem. Centr., 1901, 1,957) eliminated the methoxy- group from harmine, and obtained a base, harman, which, on the basis of the above formulze for harmine, would have the consti- tution : /\1 j CH CH and in order to obtain evidence on this point the authors have synthesised the latter bme.This derivative of quinoline, although very similar to harman, does not appear to be identical with it, and the isoquinoline structure (I)is therefore ascribed to harmine, a view which is supported by other considerations. In the first experiments on the synthesis of isoharman, an attempt was made to apply the Fischer indole synthesis to acetone-a-quinolylhydrazone, /\/\ \A/jNH*N:Chle,,I 1 N This substance, which is readily obtained from a-quinolyl-liydrazine and acetone, crystallises from light petroleum in pale yellow prisms melting at 10Zo, but indole formation could not be achieved either by heating with hydrochloric acid or zinc chloride, since hydrolysis occurred in both cases. The following indirect method of synthesis was, however, successful.o-AZdehydosuccinanirTac acid (111) was prepared by the condensa- tion of o-aminobenzaldehyde and succinic anhydride in boiling xylene solution, amd crystallises from methyl ethyl ketone in prism- atic needles melting at 115O. On boiling in aqueous solutioii with a little more sodium hydroxide than is necessary to neutralise it, this acid undergoes internal condensation with the formation of cnrbostyril-i3-acetic acid (IV), which crystallises from acetic acid in colourless needles and melts at 270O.The methyl ester of this acid melts at 176O, and is converted by aqueous ammonia at looo into the amide (V), which crystallises from dilute acetic acid in microscopic needles and melts at 258O. When this amide is boiled with phosphoryl chloride, a remarkable reaction takes place, and ChZoTonorisohurman {VI) is produced. This substance crystallises from dilute acetic acid in pale yellow leaflets melting at 127O, and is converted by boiling, in acetic acid solution, with potassium acetate into n nciitral subs\aiice, C,,H,ON,, which is very spariiigly soluble iu orgauic: t(olvents, uielts at 335O, and is evidciitly either 156 il~dro~~?torisohn1.man,the lactim, or the corresponding lactam of a-aminoquinoline-&acetic acid (VII).The solution of chloronoriso- harman in boiling amyl ether reacts with a solution of rriagnesiurri methyl iodide in the same solvent with the formation of a base which, although its investigation is not yet complete, is regarded as isoharman (VIII): CHO CH (111.) (JV.1 CH CH., CH I/\/\/\I u3 j ' cc1 \/\;\/NH NH,, I\' NH v.1 (VI.) CH, CH /\/\/\ /\/\A C*CH,,11I IICO 1 \/\/\/ \A/\/N NH N NIi (VII.) (VIII.) isollcunzan crystallises from methyl alcohol in leaflets, melts at about 213O, and, when heated in small quantities, sublimes with little decomposition. Its solution in sulphuric acid is colourless, and exhibits a bluish-violet fluorescence. The salts are crystalline and sparingly soluble in water ;the hyclrocldoricle crystallises in slender, yellow needles, and the rnemririchloride in long needles.The picrate is sparingly soluble in all solvents, but may be crystallised from methyl ethyl ketone, from which it separates in yellowish-green needles, which darken above 240° and melt and decompose at about 253O. The properties of isoharman are therc- fore strikingly similar to those of harman, which also sublimes, is readily soluble in alcohol, and dissolves in sulphuric acid to a bluish-violet, fluorescent solution. Harman melts, however, at 230°, and appears to be more soluble in hot water than isoharman. Moreover, aqueous solubions of the salts of harman exhibit a blue fluorescence, whereas the corresponding salts of isoharman do not appear to fluoresce.*141. “Blue adsorption compounds of iodine. Part I. Starch, saponarin and cholalic acid.” By George Barger and Ellen Field. The crystalline iodide of cholalic acid is in the main an additive compound of one atom of iodine to one molecule of the acid. By acidification of a solution of sodium cholalate containing iodine, the blue substance can be made to separate in the amorphous condi- tion, and then it adsorbs much more iodine. Adsorption is the most important factor in the formation of the blue iodides of starch and of saponarin, and is brought about by the cation of electrolytes, the presence of which is a necessary condition for the formation of these iodides. In all three cases the blue compounds behave like electronegativo lyophobic colloids ;their precipitation from solution by electrolytes depends chiefly on the valency of the cation, and follows Schulze’s law ;they are also precipitated by electropositive dyes.With night- blue there is a zone of optimal concentration. The lyophobic pro- perties are only slightly marked in the case of starch iodide. The distribution of iodine between the solution and the amor-phous compounds is in all cases given by an exponential formula, which in the case of saponarin and of cholalic acid only applies over a comparatively short range of concentrations. The bluc hydrosol of saponarin becomes colourless more or less abruptly at n. dilution of 1:7000, corresponding with the true solubility, when the whole of the substance becomes molecular-disperse.DISCUSSION. Prof. MORGANreferred to the interesting point mentioned by t,lic authors that salts of the more electropositive metals favoured the production of adsorption iodine complexes, and suggested a corri-parisor? of the behaviour of oaesium with that of barium aud lanthanum, since these three elements are the most electropositive members of their respective families. 142. 4L The absorption spectra of various derivatives of naphthalene in solution and as vapours.” By John Edward Pnrvis. The absorption spectra of various a-and &derivatives of naplitha-lone show that (1) the nature and type of the solution bands is c-ontrolled by tho nature and type of the snbstitiiting ahom nr group of atoms, n2nd(2) the vapours of these substances oxhibit 158 bands which are comparable with the solution bands.These results were discussed with regard to the intrinsic vibratory energy of the molecules and their valencies. 143. (( The velocity of the hydrogen ion and a general dissociation formula for acids.” By James Kendall. The following modification of the conductivity method has been used to determine the velocity of the hydrogen ion. The dissocia- tion constants for weak acids at high dilutions are found to be more or less satisfactory, according to the value employed for the velocity of the hydrogen ion. With acids of a certain limited range of strength (look between 0.1 and 1.0), one particular value alone will give a satisfactory constant. Experiments have been carried out with several acids and with different samples of water, and the value finally deduced is 347.2 at 25O, with a maximum divergence of *0.4.In more concentrated solutions the above acids diverge consider- ably from the simple dilution law. Their dissociation, however, can be exactly expressed by the formula: m2/ (1-m>v=:7c -+ c(l -m)lm. This formula is intermediate between those of Ostwald and van’t Hoff, and has been extended to all types of acids. In all cases the agreement between the calculated and observed values is within the limits of experimental error. The above formula is therefore found to be universally applicable for acids. 144. N-Chloro-derivatives of benzylidene-diamides.” By Frederick Daniel Chattaway and Alan Edulf Swinton.The benzylidene-diamides which are produced when benzaldehytl c is heated with amides, although very easily hydrolysed, yield AT-chloro-derivatives with hypochlorous acid. From lsenzylidenediacetamide the dichloro-compound has been prepared, but from benzylidenedibenzamide only the mone chloro-derivative has been obtained, this, on account of its sparing solubility, being easily isolated. These compounds show the usual general characteristics of chloroamino-derivatives. They are easily hydrolysed, even on long exposure at the ordinary temperature to moist air, benzaldehyde and chloro-acetamide or -benzamide being formed. They react vigorously with warm concentrated potassium hydroxide solution, bcnzaldchydc, potassium carbonate, and a primary aniine being produced.Probably hydrolysis first, takes place, the chloro-anzide subsequently undergoing the Hofmanii transformation under the influence of the alkali hydroxide. 145. ‘(The refractivity of sulphur in various aliphatic compounds.” By Thomas Slater Price and Douglas Frank Twiss. The densities and refractive indices at 16O and 25O of the various dithio-esters previously prepared by the authors (Trans., 1908, 93, 1645; 1909, 95, 1050) have been determined, and the corresponding ~r~olecularrefractivities calculated. From the results, the atomic refractivity of sulphur has been deduced, and the values so obtained have been compared with those deduced from sulphur compounds prepared by other investigators, especial reference being made to the optical effect of auxiliary valencies (compare Eisenlohr, Ber., 1911, 44, 3188).146. ‘‘The conditions of isodynamic change in the aIiphatic ketones. Part I. The autocatalytic reaction between acetone and iodine.” By Harry Medforth Dawson and Frank Powis. If a small quantity of iodine is added to a neutral aqueous solution of acetone, the velocity with which the iodine disappears increases rapidly as the reaction proceeds, in consequence of tho catalysing effect of the hydriodic acid which is formed as one OC the products of the interaction. The change takes place in three stages : (a) CE13*CO*CH, CH,:C(OH)*CH,; (b) CH,:C(OH)*@H, +1, Z CH2I*CI(OH)*CH,; aiid (c) CH21*CI(OH)-CH3 CH21*CO-CR3+ HI, and the halogen acid which is set free in the third stage accelerates the primary isodynamic change in proportion to the quantity present.The observed progress of the change is in agreement with the assumptiou that the second and third stages in the reaction are of relatively high speed. The initial velocity of the reaction in “ neutral ” solution appears to be much greater than can be accounted for on the basis of the original acidity, and experiments, in which small quantities of halogen acid, alkali, and sodium acetate were added to the solution at the start, seem to show that the isodynamic change is accelerated by other than acid catalysts. Although bases probably accelerate the reaction, the observed facts cannot be interpreted on the assump- tion that the change is conditioned by the presence of acids or bases, and it is suggested that water, independently of its ionising properties, plays the part of an accelerator.160 147. 6‘ Tyrosine and its derivatives containing substituents in the benzene ring.” (Preliminary note.) By Henry Stephen and Charles Weizmann. Ethyl phthalimino-p-methoxyG enzylmalonate, C,H,<~~>N*C(CH2*C,H4*0Me)(C02F:t)3, was prepared by heating moiecular quantities of p-methoxybenzyl bromide and the potassium compound of ethyl plitlialiminorrialori~~ e with xylene in an oil-bath at 145” for six hours. When purified by crystallisation from ethyl alcohol it melts at 83O.Tyrosine was obtained by hydrolysis of the above compound ((2) with concentrated aqueous sodium hydroxide, and subsequent decom- position with concentrated hydrochloric acid according to Sorensen and Rndersen’s method (Zeztsch,. plzysiol. Chem., 1908, 56, 266) ; (6) with concentrated hydrochloric acid in a sealed tube at 175O for two hours. Ethyl ph~t7~aZim~~iopipeTonylmalonate, wa.s obtained similarly by condensing piperonyl bromide and et,liyl plithaliminomalonate. After recrystallisation from methyl :LIwhol it melts at 89O. 148. 6‘ Configuration of the stereoisomeric dibromosuccinic acids.” By Alex. McKenzie. A detailed account of work of which a preliminary not0 has already been published (Proc., 1911, 27, 150). I-Dibrornosuccinic acid melts at 167-15B0, and bas [u]:; -14SO in ethyl acetate solution. The action of water on the I-acid and its barium and silver salts was examined. 149.“ The exhaustive alkylation of tetrahydroberberine.” By James Wallace McDavid, William Henry Perkin, jun., and Robert Robinson. The authors have combined tetrahydroberberine (I) successively wit,h benzyl chloride and with methyl iodide, and, by decomposing the final product with alcoholic potassium hydroxide, have obtained 161 150. ‘(The spectroscopic investigation of the carbinol-ammonium base isomerism. Benziminazole and isoquinoline derivatives.” By Charles Kenneth Tinkler. The transformation of dimethylbenziminazolium hydroxide into the corresponding carbinol, dimethylbenziminazolol, and the reverse change of carbinol into ammonium base, has been followed by ultra-violet absorption spectra measurements : In the case of the isoquinoline derivatives, evidence was obtained.of the conversion of 2-methylisoquinolinium hydroxide into 1-hyclroxy-2-methyl-1:2-dihydroisoquinoline by the action of sodium hydroxide and of the re-conversion of the carbinol into the ammonium base by the action of water, as recently suggested by Dacker (J. pr. Chem., 1911, [ii], 84, 425): By this method of investigation it appears also that the substi- tuted isoquinoline, tarconine methiodide yields a $-base. The isoquinoline base obtained by Pyman by the -oxidation of laudanosine (Trans., 1909, 95, 1266) gives spectra in ethereal, chloroform, and sodium hydroxide solution, which are almost identical with those of the hydro-derivative and $-cyanide of the base, whereas in aqueous solution the spectra of the base are in very close agreement with those of the quaternary salts of the base.From the spectroscopic results obtained with this substance it would appear that the base is more correctly represented as the closed chain carbinol 1-hydroxy-6 :7-dimethoxy-2-methyltetrahydro-isoquinoline than as the open-chain aldehyde 4:5-dimethoxy-28-methylaininoethylbenzaldehyde, as suggested by Pyman. The base 162 resembles in all respects cotarnine and hydrastinine, which have previously been investigated by this method (Dobbie, Lauder, and Tinkler, Trans., 1903, 83, 598; 1904, 85, 1005).As in these cases it appears that by the action of the water the true ammonium base is produced: MeO*Q:CH*~*CH(OH)*rMe52 MeO*$XCH*~--CH:~Me*OH MeO*C:CH*C-CH,-C H, $;H MeO*C:CH*C*CH,*CH, 151. “ Some derivatives of oxazole.” Ry Joseph Lister and Robert Robinson. A number of aryl-oxazolcs have been prepared by the deliydrn-Lion oE acylated amino-ketones in order that their fluorescelice a,ncI ultra-violet absorption spectra might be investigated. 152. (( Electrolytic reduction. Part VII. The catalytic action of copper.” By Herbert Drake Law. It has been discovered that finely divided copper exerts a powerful catalytic action on the course of reduction of the afl-un- saturated ketones and aldehydes of the aliphatic and alicyclic series. These compounds are reduced more rapidly on copper than lead, but at the same time the latter metal combines with the partly reduced product.Copper, on the other hand, remains unattacked. The nature of the reduction reaction varies with differed com- pounds. The attack may take place either at the carbonyl group or the unsaturated linking, or at both simultaneously. Hydro-carbons, saturated and unsaturated alcohols, saturated carbonyl compounds, and complex double molecules are formed either singly or in mixture. 153. (‘The two sulphides of P-naphthol.” By Cecil Reginald Crymble, Kenneth Ross and Samuel Smiles. Henriques (Ber., 1894, 27, 2999) has shown that &naphthol sulphide (m. p. 211O) may be converted into another sulphide of lower melting point (153O) by oxidation and subsequent reduction of the product; it has also been claimed that these sulphides are stereoisomeric.The authors have compared some resctions of these compounds, and the evidence bearing on the relationship between them was considered. The conclusion was drawn that the hypothesis of stereoisomerism is insufficient, and that the two sulphides differ in their atomic structure. 163 154. a-Hydroxyhippuric acid and a new test for hippuric acid.’’ By Paul Haas. a-Hydroxyhippuric acid is prepared by adding bromine to ilr gently warmed mixture of hippuric acid and red phosphorus sus- pended in carbon tetrachloride, and pouring the resulting mixture into water.The test for hippuric acid depends on its conversion into a-hydroxyhippuric acid, and the subsequent hydrolysis of this substance to benzamide and glyoxylic acid, the latter being detected by the addition of a protein solution and concentrated sulphuric acid. 155. (( The constitution of the aldol bases.’’ By Muriel Gwendolen Edwards, Ralph Eddowes Garrod, and Humphrey Owen Jones. The two ‘‘aldol bases,” C,,H,,ON, prepared from m-4-xylidine and acetaldehyde, were studied by Jones and White (Trans., 1910, 97, 633), and it was found that they were interconvertible by the action of acids, but not by the action of heat; both gave the same benzoyl compound, the same oxime, and the same condensation product with m-4-xylidine, but they gave different nitroso-deriv- atives.In order to arrive at a definite conclusion as to the cause of this interesting case of isomerism, the study of these compounds has been extended, and the corresponding bases obtained from p-toluidine, $-cumidine, and 3-bromo-p-toluidine have been examined. The clue to the solution of the problem was found when it was established that the isomeric aldol bases from p-toluidine gave two different monobenzoyl compounds, and that the nitroso-derivatives of these bases could be benzoylated. It was then found that by treatment with acetyl chloride in pyridine solution diacetyl derivatives could be prepared, and in a similar way two isomeric dibenzoyl derivatives were obtained from the xylidine aldol bases.These observations can only be accounted for on the assumption that the isomeric aldol bases are the cis-and trans-stereoisomerides of hydroxytetrahydroquinoline derivatives, for exampIe : CH-OH irr the ease of the p-tsluidine compounds. This view explains all the known facts, and also accounts for the non-formation of similar compounds from mesidine anti 5-bromo-m-4-xylidine. The hydroxytetrahydroquinoline ring must be capable o€ fission very easily on account of the formation of the oxime, the inter- conversion of the isomerides by acids, and the formation of the same condensation product with xylidine in the case of the aldol bases derived from xylidine. These condensation products, the double Schiff's bases, appear to precede the aldol bases in the interaction of acetaldehyde and amincs, and as they give monobenzoyl and mononitroso-derivatives their structure is best represented as: C,I-I,Me*N€I*CHMe*CH,.CR :N*C,H,Me.156. '' Some quinoline and tetrahydroquinoline derivatives obtained from aldol bases." By Ralph Eddowes Garrod, Humphrey Owen Jones, and Percy Edwin Evans. During the study of the constitution and properties of the '' aldol bases " and their conversion under the influence of heat or of acids into quinoline and tetrahydroquinoline derivatives, the behaviour of the aldol bases derived from $-cumidine and S-bromo- p-toluidine has been studied. The former are converted either by heat or by acids into a mixture of 2 :5 :6 :8-tetramethylquinolinc (m.I>.27-28O) and 2 :5 :G :8-tetramethyltetrahydroquinoline iii equimolecular proportions. When the aldol base of 3-bromo-p-toluidine is heated to 150-200° it changes quantitatively into the hydrobromide of 2 :6-dirnethylquinoline7 according to the following scheme : CEOH CH On boiling with acids, however, 8-bromo-2:6-dimethylquiiioline (m. p. 96-9F) and 8-brome2 :6-dimethyltetrahydroquinoline are produced, together with a small quantity of 2 :6-dimethylquinoline and hydrogen bromide. 157. (‘The viscosity of ether-alcohol mixtures.” By Frank Baker. ‘I‘hc viscosities of mixtures in different proportions of thc follow-iiig ethers and alcohols have been observed-methyl, ethyl, arid propyl alcohols ;ethyl ether, anisole, and phenetole. From the results obtained, it was concluded that dissociation of the alcohol and associalion to an ether-alcohol complex took place in these mixtures. The bearing of these results on the viscosity of mixtures in general was discussed, and the relation =qlln+ (1-a)y2n shown to be empirical.158. ‘‘Morphotropic relationships between racemic compounds and their optically active components. ” By George Jerusalem. The author has examined crystallographically a number of optically active and racemic compounds, and studied the relation- ship observahle between the crystalline structure of racemic com-pounds and their optically active cornponent,s in these and many other cases. hi all the instances examined it is found that a close niorphotropic relationship exists between these substances, and that the relationship is precisely of the kind foretold by the theory of BarIow and Pope concerning the connexion of crystalline form with chemical composition and constitution. 159.‘‘ The action of sodium methoxide on 2 : 3 :4 :Ci-tetrachloro-pyridine. Part I.” By William James Sell. As is well known, haiogen derivatives of pyridine, when heated with sodium methoxide frequently give rise to hydroxy- instead of methoxy-compounds, but no satisfactory explanation of this reaction has hitherto been offered. The author finds that wlieii 2 :3 :4:5-tetrachloropyridine is heated to 205O with sodium methoxide in a sealed tube, a mixture of gaseous products is produced, mainly composed of methyl ether and hydrogen.It is suggested that the methoxy-derivative of pyridine first formed reacts with the excess of sodium methoxide to produce methyl ether, thus : (1) RC1+ NaOMe =ROMe +NaCl. (2) ROMe + NaOMe= RONa + Me,O, ai1~1that the hydrogen is produced by tho action ol’ s~diitt~i hydroxide on the methyl alcohol present, with produclion of sodium formate and hydrogen. 166 ADDITIONS TO TIIF, LIBEARY.
