Issued 11/6/09 PROCEEDINGS OF THE CHEMICAL SOCIETY. Vol. 25. No.358. Thursday, June 3rd, 1909, at S.30 p.m., Professor HAROLDB. DIXON,F.R.S., President, in the Chair. Certificates were read for the first time in favour of Messrs. : Hardee Chambliss, Ph.D., 56, W. 36th Street, New York City, U.S.A. Edward Walter Taplin, Church House, Heavitree, Exeter. A certificate has been authorised by the Council for presentation to ballot under Bye-Law I, par. 3, in favour of Dr. Hassum A. Lakhani, Murud Janjira, India. WIGGLESWORTHProfessor FRANK CLARICE,o f Washington, then delivered the Wolcott Gibbs Memorial Lecture, at the conclusion of which Professor Sir JAMESDEWAH.moved a vote of thanks to Professor Clarke. Professor THORPE, in seconding the motion, congratulated the Society in securing in their Honorary Foreign Member, Prof.Clarke, one so eminently capable of doing justice to the signal services which his deceased countryman, the late Dr. Wolcott Gibbs, had rendered to chemical science. The Chemical Society justly prided itself on the distinction conferred upon it by the distinguished men who constituted the class of its Honorary Members. They honoured them living, and when death summoned them from the scene of their activities, they sought to honour them dead, and by lectures such as they had heard 172 to-night to commemorate their achievements and to indicate their relation and true position towards the science which they had laboured to advance. In putting together the story of Dr.Wolcott Gibbs’ life and work, Dr. Clarke had enjoyed the advantage of contact and intimate personal acquaintance with his subject, and it was this personal note which rendered his discourse specially interesting and valuable. Professor OTTOX. WITTexpressed his great satisfaction at having been able to listen to Professor Clarke’s lecture, which not only deserved the greatest praise for its literary and scientific merits, but had also a great personal interest for himself. In the German Chemical Society it was customary for the death of prominent members to be announced by the president in the meeting following the sad event, and a short biographical sketch had to be given on such occasions, pending the publication of an elaborate essay at the end of the year, Thus it had been his (the speaker’s} duty to give an account of the life and labours of Wolcott Gibbs in one of the meetings of the Society.In compiling the necessary notes, he had observed how scant the existing information was, and the short time at his disposal had not allowed him to ask Professor Clarke for a few notes as he would like to have done. There were a few things, however, which made it quite certain that Gibbs, who was an honorary member of the German Chemical Society as well as of the English one, had been deserving of the greatest esteem. It was quite evident that he had enjoyed the sincere friendship of the great founder of the German Society, 9.W. Hofmann, whose name was also a household word amongst English cheniists.And it was equally certain that Gibbs possessed great merits as a teacher and as the head of the brilliant and successful school of American chemists, of which Professor Clarke, whom the speaker had learned to know and to admire during his stay in the United States, was tho most distinguished representative. Whilst supporting the motion for a vote of thanks to Professor Clarke, he begged to thank the President for having given him this opportunity for paying a tribute of personal admiration both to the memory of Wolcott Gibbs and to Professor Clarke, who had pictured the life and the work of his dead master in words that had come from the depth of his heart. Professor CHARLES said that the honour paid him by BASKERVILLE the President in asking him to support the vote of thanks proposed by Sir James Dewar was, he knew, intended as a personal one.He was endeavouring to fill the Chair, the third in line, first occupied by the distinguished lamented subject of Dr. Clarke’s eloquent eulogy. He wished, however, to emphasise something more significant. As mentioned by the lecturer, Wolcott Gibbs was the founder of the 173 Union League Club of New York, which organisation sought to preserve the Union. His (the speaker’s) father and all his relations sought to dismember that Union for reasons they thought good. The Union was happily preserved, however, and a scion of the Confederate States was now carrying forward the educational work inaugurated by the deceased patriot, Chemistry thus showed itself in a social way as the crucible of civilisation.It gave him peculiar personal pleasure to support the motion for another reason unknown to many of those present. Professor Clarke mas his chemical grandfather, for he taught Professor Dudley, who mas also present, and who in turn had taught him (the speaker). His pride in the delightfully charming manner in which Dr. Clarke, the pupil, had shown his appreciation of his former master could therefore well be understood. Tbe PRESIDENTsaid that, in its Memorial TJectures, he thought the Chemical Society had learnt to look for three excellences. They wished in the first place to have recorded the main steps in the career of the distinguished chemist whom they were met to commemorate, so that they might appreciate the difficulties he faced and how he surmounted them-difficulties which could only be made real to them by one who was a past master of their science ;secondly, they looked for some personal and sympathetic touches to tell a younger generation what kind of man was he who was gone; and lastly, they were delighted when the story was told them, not only scientifically and sympathetically-but with that arrangement and perspective and charm of language which could turn even chemistry into literature.They could congratulate themselves that in all these excellences the lecture of Prof. Clarke fulfilled, and more than fulfilled, their ideals. The vote of thanks was put to the meeting, carried by acclamation, and acknowledged by Professor CLARKE.Of the following papers, those marked * were read : *154. ‘‘The molecular weight of tetraethylammonium bromide and the atomic weight of carbon.” By Alexander Scott. The author gave an account of his endeavours to determine the molecular weight of a hydrocarbon with a degree of accuracy com- parable to that attained in the determination ofthe atomic weights of many elements. This has been done for C,HIG by titrating pure t etraethylammonium bromide against pure silver, after the manner of Stas. To precipitate 107.93 parts of silver, 210.324 parts of 174 N(C,H,),Br were required, whilst for the same weight of silver 97.995 parts of ammonium bromide were necessary.Subtracting from 210.324 = NC8H,,Br 97.995 = N H4Br. we obtain 112.329 = C,H,, If we take H= 1.0075, then HI,= 16.12, which gives 112.329 -16.120=96.209 =C, or C = 12.026. This number has been corroborated by a titration made in the same way of a small quantity of tetramethylammonium bromide, which gave 154*150=N(CH,),Br, and, similarly, 56,155 for C,H, and C = 12.084. Taking 107.88 as the atomic weight of silver, we get C= 12.018. DISCUSSION. Professor F. W. CLARKEcalled attention to the fact that the new value proposed for the atomic weight of carbon was notably higher than that found by recent investigators with physical methods. From the densities of carbon dioxide, carbon monoxide, and met'hane, the atomic weight of carbon was very near 12.In Lenher's deter- minations of the atomic weight of tellurium, a value had just been found of 127.33, calculated with the international figures for silver, potassium, chlorine, and bromine of several years ago. This result was lower than the best results obtained by others. But on recalcu- lating Lenher's work with the new value for the other atomic weights, the value for tellurium was 127.55, in close agreement with former determinations. Hence, the discrepancy was due, not to the work done, but to the antecedent factors used in calculation. How far the discordance in the figures for carbon might be due to simiIar causes it was too soon to say, but part of it was thus to be explained.Sir W. RAMSAYcalled attention to the possibility of included mother liquor in the ammonium bromide and the tetraethylamrnonium bromide. pointed out that the methods employed in pre-In reply, Dr. SCOTT cipitating and drying the various specimens of the salt, as well as the very close agreement of the results, seemed to exclude all probability of the dried salt containing any mother liquor. The atomic weight taken for silver (107.93) rendered the results more readily comparable with those of Stas, whilst the value 107.88 at present adopted by the International Committee, as Dr. Thorpe had pointed out, was probably only of transient interest and might, by further research, be still further lowered. 175 155. rate of formation of azo-derivatives from benzenoid The 6' diamines." By Victor Herbert Veley.It was shown that (i) the rate of formation, as studied by a tinto-meter method, of azo-compounds from benzenoid diamine hydro-chlorides and sodium nitrite is conditioned by the hydrochloric acid and monohydrochloride liberated by hydrolysis. It is an example of a simultaneous linear reaction expressed simply as Ax/At =k. (ii) The total amount of dyestuff capable of being formed, or range, is a linear function of concentration, but the increase of rate is a logarithmic function of the concentration expressed as logfin=logk, + alogc (c =concentration, cc =constant to be evaluated from the results). (iii) The rate is a logarithmic function of absolute temperature according to the expression kJk =(Tl/5!')m.(iv) The addition of hydrochloric and other acids produces an initial acceleration, but a total retardation, the reaction sooner coming to an end, and consequently the amount of dyestuff capable of being formed is thereby diminished. (v) The substitution of hydrogen by the methyl grouping (com- parison of phenylene- and tolylene-diamine-Bismarck Brown and Vesuvine) causes a slight decrease in rate, but a considerable decrease in the total amount of dyestuff capable of being formed. It is considered probable that this is a result of the more ready decomposition of the intermediate diazo-compound in the case of the latter than in that of the former. 156. ''The synthesis of substances allied to cotarnine." By Arthur Henry Salway.The material employed as the starting point in this investigation was myristicin (3-me thoxy-4 :5-methylenedioxy-l-allylbenzene),which was obtained from the essential oil of nutmeg (compare Power and Salmay, Trans., 1907, 91, 2037). The successive stages in the synthesis are represented by the following compounds : (I) myristicin, (11) isomyristicin, (111) myristicinaldehyde, (IV) nitromyristicin-aldehyde, (V) nitromethoxymethylenedioxycinnamic acid, (VI) keto-methoxymethylenedioxydihydroquinoline, (VII) ketomethoxymethyl-enedioxymethyldihy droquinoline, and (VIII) oxyisocotarnine. 176 (111.)

Ketomethoxymethplenedioxydihydroquinoline, ketomethoxymethyl-enedioxymethyldihydroquinoline,and oxyisocotarnine are closely re-lated to cotarnine, and their physiological action is at present under investigation.An account was also given of several attempts to synthesise cot arnine, whicb, however, were unsuccessful. 157. (( Monomethyl laevulose and its derivatives. Constitution of laevulosediacetone.” By James Colquhoun Irvine and Alexander Hynd. Lwulosediacetone yields on methylation by the silver oxide reaction a crystalline derivative (monomethyl a-Zaewulosediacetone), melting at 1:[ahaving115O, and -136.4’ in methyl-alcoholic solution. The compoupd is very easily bydrolysed by dilute acids to give mono-methyl Zue~loae, which is apparently the first definite example of a mono-substituted sugar other than the glucosides or the metallic derivatives. The sugar crystallises from ethyl acetate in the pure a-form, which displays mutarotation in the downward sense : [a]: -70~5~-+ -53*1°.On the other hand, fusion gives an excess of the p-form, and the reverse optical change ensues on solution. The compound yielded monomethylglucosaxone as yellow needles, melting at 142O, and was oxidised by bromine water to a@-dihydroxp-y-methoxybutyric acid. These results shorn that the methyl group in the alkylated ketose is in the &position with reference to the reducing group, and, accord- ing to this view, the structure of lzevulosediacetone must be 177 ,-+--IFH2*7 7H $!H*CH*CH,*OH 0 00 0 \/ \/cc: /\ /\Me Me Me Me In addition, it has been shown that the alkylated sugar condenses readily with acetone or with methyl alcohol, and the products thus obtained are interconvertible under suitable conditions.The specific rotations of the various compounds described show that the total optical effect resulting from complete methylation of the sugar moIecule is the additive sum of oppositely directed values. 158. '' Optically active 4-oximinocycZohexanecarboxglicacid and the configuration of the oximino-group." (Preliminary note .) By William Hobson Mills and Alice Mary Bain. When a sufficiently dilute solution of equiniolecular proportions of 4-oximinocyclohexanecnrboxylic acid (W.H. Porkin, Trans.,1906, 85, 4'17) (4.7 grams) and quinine (9.7 grams) in ethyl acetate is allowed to evaporate slowly at the ordinary temperature, a quinine salt crys-tallises in silky needles during the course of two or three days. The salt thus obtained was recrystallised three times from ethyl acetate and then decomposed by suspending it in water, carefully adding a slight excess of dilute aqueous sodium hydroxide, and extracting repeatedly with ether to remove quinine. There was thus obtained a slightly alkaline solution of sodium salt, from which all quinine had been removed, corresponding with about 1.8 grams of oximino-acid. On polarimetric examination in a 2-dcm. tube, very distinct Ia?vorotation was observed, namely, ad -4.4'.The optical activity was immediately destroyed by acidification with dilute hydrochloric acid. From the above observations, it appears probable that the sodium salt of 4-oximinoc~~cZohexanecarboxylicacid can exist in a dextro- and laevo-modification, as well as the inactive form corresponding with the acid described by Perkin. Since in a compound of this constitution enantiomorphism is possible only if the three valencies of the nitrogen atom of the oximino-group do not lie in one plane, the two active forms must correspond with the two configurations* : * An alternative constitution for the active salt, /CH,*CH,C@,Nn*CH \C*NH *OH,\C:H;CH is very improbable, since acidification, which wonld be expected to favour the gronpiug :C*NH'OH relatively to C:NOII, at once destroys the activity.H CO,Na H C0,K:i /\ pz p z CH, CH, CH, CH, \/ \/I=I 5N N ‘OH HO/ The existence of an optically active form of this substance thus affords evidence of the validity of the fundamental hypothesis in the Hantzsch-Werner theory of the isomerism of the oximes. 1% is also of interest in connexion with the recent work on optically active substances which do not contain an asymmetric carbon atom’in the narrower sense (Perkin and Pope, F~an8.,1908, 93,1075 ; Harding, Haworth, and Perkin, ibid., 1943; Perkin, Pope, and Wallach, P1’oc*7 1909, 26, 83; also Marckwald and Meth, Ber., 1906, 39,1171, etc.). The authors are proceeding with this investigation, and hope in due course to submit a complete account of their results.159. ‘‘ cycZoButane-1 : 3-dicarboxylic acid and some of its deriv- atives.” By William Henry Perkin, jun., and John Lionel Simonsen. The authors described the action of hydrobromic acid and of bromine on cycZobutane-1 :3-dicarboxylic acid and on norpinic acid, and discussed the conditions under which disruption of the cyclobutane ring takes place in these and analogous cases. 160. ‘‘The oxidation of mucic acid in presence of iron.” By Ftederic Ferraboschi. The oxidation of niucic acid by means of hydrogen dioxide in presence of iron has been investigated. The principal product is a strongly reducing acid, which appears to be a dihydvoxymucic mid. It may also be regarded as a diketonic acid, namely, dihydroxydiketo-adipic acid.Its dihydraaone has been prepared. Parallel experiments on the oxidation of saccharic acid gave analogous results, but the products obtained are not identical with those derived from mucic acid, 179 161. The production of ozone in the interaction between hydrogen 6‘ dioxide and sulphur dioxide.” (Preliminary note.) By Frederic Ferraboschi. In an investigation of the well-known reaction between sulphur dioxide and hydrogen dioxide, it has been observed that ozone is pro-duced in considerable quantities. It is found that when sulphur dioxide is rapidly led into a solution of hydrogen dioxide (both ‘(10 volume” and “ 20 volume” strengths mere used), it is entirely destroyed in passing through a layer 2 or cm.deep. Each bubble almost, but not entirely, disappears, and ozone is produced in quantities sufficient to be easily detected by its odour. Its presence may be further proved by its actions on starch- potassium-iodide paper, and on paper moistened with an acetic acid solution of pp’-tetramethyldiaminodiphenylmethane(“ tetra-base”). The production of ozone can also be observed when excess of hydrogen dioxide is added to aqueous sulphurous acid. The same effect is not produced in the reaction of hydrogen dioxide with sodium sulphite or thiosulphate, or when sodium or barium peroxides, either with or without an acid, are added to aqueous sulphurous acid, The reaction is being examined quantitatively. 162.“The action of sulphur monochloride on salts of organic acids : a convenient method of preparing anhydrides.” By William Smith Denham. When sodium benzoate is boiled with a solution of sulphur mono-chloride in light petroleum, a compound of the probable formula (C,H5*C0,S), is formed, which is very unstable and soon decomposes, giving sulphur, sulphur dioxide, and benzoic anhydride. The formation of this compound takes place more easily if the silver salt is used. Similar derivatives of acetic, propionic, phenylacetic, aiid the toluic acids have been obtained. The easy formation and simple decomposition of these compounds suggests a method of preparing the anhydrides of the acids. Sulphur monochloride reacts also with metallic derivatives of imides.163. The velocity of decomposition of nitroglycerin by heat.” Part I. By Robert Robertson. Nitroglycerin (glyceryl trinitrate) is heated in a current of carbon dioxide in an apparatus arranged to condense any volatilised nitro- 180 glycerin and, on rotation about an oblique axis, return it to be again heated. The niZrogen peroxide evolved is determined by Robertson and Napper's spectroscopic method (Trans.,1907, 91, 76 1). The products of decomposition are then passed over red-hot copper and copper oxide, and the nitrogen is measured over potassium hydroxide. It mas found that nitroglycerin decomposes uniformly, yielding nitrogen peroxide, that the rate OF decomposition is;a * function of the temperature, being doubled for every 5O between 95' and 125O, and that the rate of decomposition is higher than that of guncotton.ADDITIONS TO THE LIBRARY.
