[Issued 28/11/14 PROCEEDINGS OF THE CHEMICAL SOCIETY. Vol. 30 No. 434 Thursday, November 19tmh, 1914, at 8.30 p.m., Professor W. 13. PERKIN,LL.D., F.R.S.,President, in tlhe Chair. The PRESIDENTmentioned, with deep regret, that Mr. John Gunning Moore Dunlop, of Caius College, Cambridge, who was elected a Fellow on Juno 17th, 1909, had been killed in action on Augusti 27th. It was announced t,hat the Council had passed tho following Resolution : “ The President; and Council of the Chemical Society, at their first meeting of the Session, desire to be associated with the state inents and opinions set forth by certain scholars and public men in t.heir manifesto published in The Times of October 21st, 1914.” It was also announced that a Research prize of the value of g200 has been placed by Sir Robert Hadfield, F.R.S., Past-President of the Iron and Steel Institute, at the disposal of the Council of that> rtlstitute, to be awarded by the Council to the author of the best contribution to the publications of the InsLitute on the subject of the “Different, Forms or Combinations of Carbon in Iron, Steel, and Alloys of Iron with other Elements.” Competition for the prize is open to metallurgists, chemists, and others interested in metallurgy, and it is proposed that the prize shall be awarded ah the Annual General Meeting of the Institute in May, 1916, for the best paper presented before February lst, 1916. 268 Intending competitors are requested to communicate, in the first place, with Mr.G. C. Lloyd, Secretary of the Iron and Steel Insti- tute, 28, Victoria Street, S.W., from whom further information may be obtained. Certificates were read for the first time in favour of Messrs. : Frank Buckley, 10, Berry Street, Greenfield, Oldham. Reginald Robert Kuntzen, Grammar School, Ipswich, Queens- land. Harry Shulman, 21, Tredegar Square, Bow, E. A Certificate has been authorised by the Council for presenta-tion to ballot, under Bye-law I (3), in favour of Mr. Thomas Clifton Hurford, Puket, Siam. Of the following papers, those marked * were read: "277. '(Studies in the camphane series, Part XXXVI. N-Chloro-aminocamphor." By Martin Onslow Forster and Max Schlaepfer. N-ChJoroamino camphor, C8H,,< cH"HC1, prepared by adding ICO alkaline chloroamine to aqueous aminocamphor hydrochloride, crystallises from petroleum in colourless needles melting at 43O and decomposing at 85O; it liberates iodine from potassium iodide, and regenerak aminocamphor with sodium sulphite.The dry sub- stance rapidly changes into a honey-like mass, losing chlorine, and solutions in benzene or petroleum quickly deposit aminocamphor hydrochloride and contain the anhydride of cyanolauronic acid. In acetone it also gives aminocamphor hydrochloride along with a conzpound, C,,HBON, melting at 155O. Ammonia converts it into iminocamphor, and aniline is oxidised to azobenzene. DISCUSSION. Prof. GREENsuggested that camphorylhydrazine might possibly be obtainable either by treating chloro(or bromo)camphor wiCli hydrazine, or by the action of dry ammonia gas on N-chloroamino- camphor in a non-aqueous solvent."278. gL The dissociation pressures of alkali bicarbonates. Part 11. Potassium, rubidium, and csesium hydrogen carbonates." By Robert Martin Caven and Henry Julius Salomon Sand. The dissociation pressures of the hydrogen carbonat-es of potass-ium, rubidium, and czesium have been determined by means of the apparatus formerly employed for sodium hydrogen carbonate (T., 1911, 99, 1359), and curves have been drawn which accord with the formula : log p=a-b / T. The values of the constants are : for KHCO,, a= 10.832, b = 3420 ; for RbHCO,, a= 12.712, b =4300 ; for CsHCO,, a= 16.930, b =6300.From the values of the constant h the following heats of disscciation per 2-gram-molecules of hydro-gen carbonate are derived : KHCO,, 31,460 cals. ;RbHCO,, 39,560 cals. ; CsHCO,, 57,960 cals. Tho results of the experiments on the dissociation pressures of the alkali hydrogen carbonates show not only that the stabilities towards heat of these salts increase with rise of atomic weight, but also that sodium hydrogen carbonate is widely separated from the other three salts in stability. This furnishes another illustration of the fact that a break occurs in the gradation of properties of compounds of the alkali metals at the point of transition from the short to bhe long periods in the periodic classification of the elements 279. “The removal of sulphur from silver.” By Crellyn Colgrave Bissett.The effect produced by adding varying percentages of copper and iron respectively to molten silver containing silver sulphide in solution has been determined. In the case of iron it was found that ferrous sulphide was formed, the whole of the silver in combination with sulphur being displaced by iron if sufficient for this purpose was added. Ferrous sulphide is insoluble in silver. Copper was found to behave differently. It was only when a considerable percentage of the copper had alloyed with the silver that the sulphide was removed completely from solution. Even * under these conditions the sulphide layer still contained a fairly large percent’age of silver. The results obtained by blowing a current of dry air through molten silver containing sulphur have also been determined.280. Osmotic pressure of alcoholic solutions.” By Tudor Williams Price. Measurements have been made of the vapour pressure of alcohol and of alcoholic solutions of carbamide and nitsobenzene, of various concentrations, at’ 20°, 30°, 40°, 50°, and 60° by the air- bubbling method. 270 Tlis densities were also determined. The osmotic pressures were calculated froin tlie forniula : where 1’=osmotic pressure of the solution. a =coefficient of compressibility of tlie solvent. p =vapour pressure of the solvent. pf=vapour pressure of the solution. V,=molecular volume of the solvent. 281. “The polysulphides of the alkali metals.Part 11. The polysulphides of potassium.” By Alexander Rule. In continuation of previous work on the polysulphides of the alkali metals (Rule and Thomas, T., 1914, 105, 177) the author has investigated the action of sulphur on alcoholic solutions of pure snhydrous potassium hydrosulphide. With varying propor- tions of sulphur the only polysulphide product obtained was the pentasulphide, which was readily isolated in the pure state. It is an orange-red, crystalline compound, melting at about 220O. By determining the amount of hydrogen sulphide evolved by the action of varying amounts of sulphur on a constant amount of hydrosulphide throughout, it is also shown that the penta-sulphide is the polysulphide present iu predominatirig amount in solution.Considering the results in general, and comparing them with those obtained for sodium, and for rubidium and czsium by Biltx and Dorfurt (Ber., 1905, 43, 53; Zeitsch. anorg. ChPm., 1906, 48, 297; 50, 67), the stability of the higher polysulphides appears to increase with increase in the atomic weight of the alkali metal. The highest stable polysulphide of sodium is the tetrasulphide. The pentasulphides oT potassium, rubidium, and c&um are per-fectly well defined, and exhibit an inverse order of solubility with increasing atomic weight, thus coming into line with the platini- chlorides, alums, etc., of the same metals. No indication of the formation of a hexasulphide of potassium has been obtained in the course of the author’s experiments, whereas Biltz and Dorfurt were able to show the existence of hexasulphides, both of rubidium and cesium.The possible influence of the alkali metal on the number of atoms of sulphur taken up to form the polysulpt-iide complex was discussed. 27 1 282. “The progressive bromaation of toluene.” (A reply.) By Julius Berend Cohen and Pavitra Kumar Dutt. In the appendix to a paper on the bromination of toluene (Rec. truv. chim., 1914, 33, 183) Prof. A. F. Holleman has thrown doubt on the production of m-bromotoluene by the direct bromina- tion of toluene which the authors have observed (T., 1914, 105, 504). Prof. Hollemsn says: ‘(I1 me semble que la preuve que MM. Colien et Dutt ont donn6e de sa pr6sence n’est pas tout-kfait rigoureuse.Car d’abord ces savants se sont places dans des circon- stances d6favorables pour la decouverte de petites quantites de l’isomkre meta en faisant reagir le brome et le tolu6ne mol6cule par molBcule, ce qui cause la formation de produits bromes sup6rieurs. Par oxydation ceux-ci donnent des acides dibromobenzoiques qui sont tr&s difficiles B &parer, aussi bien entre eUx que dea acides monobromobenzoiques. Nonobstant que les savants nommes aient trouv4 des points de fusion de l’ether m6thyliquei et de l’acide, correspondant B peu prks avec ceux des substances m6ta pures, cette preuve ne peut donc 6tre regard& comme dgcisive, surtout parce que ni l’essai de la melange, ni des analyses ont corrobor6 ce r6sultat.” Prof.Holleman’s criticism is to some extent justified, although the boiling point of the mixed bromotoluenes (180-190O) would obviously exclude the presence of dibromo-derivatives which boil at about 240O. In order to meet this criticism the authors have (1) mixed the m-bromobenzoic acid (m. p. 157-158O), obtained by the oxidation of the bromotoluene by direct bromination, with a pure specimen prepared by brominating benzoic acid (m. p. 157*5-158-5O), and found that the mixture melted at 157-158O; (2) made an analysis of the acid with the following result: 0.1232 gave 0.1160 AgBr. Br =40-06. C7H,O2Br requires Br =39% per cent. The above affords conclusive proof that the substance in question is m-bromotoluene. 283, ‘(Researches on silicon compounds.Part VI. Preparation of silicon tetrachloride, disilicon hexachloride, and the higher chlorides of silicon by the action of chlorine on 50 per cent, ferrosilicon, together with a discussion on their mode of forma-tion.” By Geoffrey Martin, The author described a very cheap process of preparing the chlorides of silicon by the action of chlorine on 50 per cent. ferro- 272 silicon. He has investigated the most favourable conditions for the action to take place, and described his apparatus, whereby he produced more than 50 kilos. of silicon tetrachloride and 3 kilos. of disilicon hexachloride by passing 150 kilos. of chlorine over about 50 kilos. of 50 per cent. ferrosilicon. The apparatus used for distilling large amounts of the chlorides of silicon in absence of atmospheric moisture was also described. By this process the author prepared some kilos.of the hitherto difficultly accessible and costly disilicon hexachloridc, Si,Cl,, and was able t.o investigate its properties more carefully than has hitherto been possible. He also obtained 180 grams of trisilicon octachloride, Si,Cl,, and smaller quantities of higher chlorides. Gattermam and Weinlig (Ber., 1894, 27, 1943) attributed the formation of disilicon hexacliloride in the chlorination of silicon to the fact that silicon tetrachloride reacted with silicon to produce the hexachloride, thus : Si +SSiCl, =2Si2C1,. Experiments were quoted, however, to show that Gattermann and Weinlig were wrong in this, as at the low temperatures employed in the pre- paration of silicon tetrachloride the latter doss not react with silicon to produce noticeable amounts of disilicon hexachloride. The only explanation that meet*s the facts of the case is the supposition that in elementary silicon or in metallic silicides the silicon atoms are directly united in chains, and that the first action of chlorine on silicon (or metallic silicides) is not immedi- ately to break up these chains of silicon atoms, but that there are first produced complex chlorinated products still containing chains of silicon atoms directly united.These complex chlorides are then attacked by more chlorine, and deconipose into simple chlorides, silicon tetrachloride being thus not the first product of chlorina- tion, but rather the final product.284. Researches on silicon compounds. Part VII. The action of ethyl alcohol on disilicon hexachloride.” By Geoffrey Martin. When ethyl alcohol acts on disilicon hexachloride the following nine substances are, theoretically, capable of being produced, none of which has hitherto been described: SiCI, SiCI, SiCI,*OEt Sic1, SiCl,*OEt I I I SiCI,*O Et &iCI(OEt), SiCI,*OEt Si(OEt), SiCl(0Kt ): \ / Y-YTwo forms. Two forms. S::I(OE*), SiC!(OEt), Si(OEt), Ri( OEt)3 I Islci2* Et~ &ic1( IOE~) SiCl(OEt)2 si(OEEt)3 \A T*xn foiiiiq. OItP f01713. Olie form. 273 The preparation and properties of a number of these substances were described. They are all colourless oils, decomposed by water with the production of explosive white hydroxy-compounds, which dissolve in alkalis evolving hydrogen, thus verifying the author’s theory (Bey., 1912,45,2097; 1913, 46,3289) that in the presence of attached oxyger atoms directly linked silicon atoms are decom- posed by alkalis, thus: + Each direct Si-Si linking thus corresponds with the evolution of one molecule of hydrogen. The curious circumstance was noted that great cold is produced when alcohol acts on disilicon hexachloride, a vigorous action going on jtt the same time.Although the first equivalents of chlorine of the disilicon hexachloride molecule are readily displaced by ethoxy-groups, yeii it was shown that as each successive chlorine atoM is removed the displacement proceeds with greater and greater difficulty, so that the substances Si&l,(OEt), and SiCl(OEt), are scarcely acted on by ethyl alcohol at the ordinary temperature. 285.“Investigations on the dependence of rotatory power on chemical constitution. Part XI. The co-ordination of the rotatory powers (a)of menthyl compounds, (b) of the menthones and (c) of the borneols,” By Joseph Kenyon and Robert Howson Pickard. One “characteristic diagram ” (compare Armstrong and Walker, Proc. Roy. SOC.,1913, [A], 88,388) serves to co-ordinate the rota- tory powers for different wave-lengths, not only of &menthol, d-neo- menthol, and their esters, but also of I-menthylamine and its simple derivatives. This method of plotting rotation values fails when the compound contains two possible and dissimilar centres of dynamic isomerism, such as, for example, the menthyl esters of the nitro- and o-iodo-benzoic acids and 2-naphthylmenthylcarbamide.The rotatory powers, however, of the menthyl esters of a number of mono- and di-nitrobenzoic acids can all be co-ordinated on another diagram, which differs considerably from that drawn for the simpler menthyl compounds. The rotations of I-nienthone and d-isonienthoiie can also be co-ordinated on a characteristic diagram, whilst the same method has been applied successfully to the rotatory powers of I-borneol, d-isohorneol and esters of these. 274 286. LL The rotatory powers, refractivities and molecular solution- volumes of cinchonicine and some derivatives.” (Preliminarynote.) By David Henry Peacock.The greater number of the investigations on the connexion between rotatory power and constitution have been carried out on esters. Pope and Winmill (T., 1912, 101, 2309) examined the derivztives of tetrahydroquinaldine, and it was thought that a similar examination of cinchonicine and its derivatives might produce useful results. The preparation of the acyl derivatives proved, however, exceedingly troublesome. In several cases, even after many modifications of the method of working, only uncrystal- lisable gums were obtained. Owing to the pressure of other work this investigation has been temporarily stopped, but the following results are given as of interest.The examination of the physical expressions for refractivity and optical rotatory power at once shows that there should subsist a close connexion between the two properties (see, for example, Wood’s “Physical Optics ”). Optical rotatory power may be altered owing to a change in the degree of asymmetry of the molecule; for instance, it vanishes when the molecule becomes symmet8rical, or by such changes in the internal forces as affect both rotatory power and refractivity, for instance, the presence of conjugated double bonds. Substitution may act in both ways, and by a comparison of its effect on both properties it might be possible to separate these two effects; at present, however, the only means of deducing the refractivity of a dissolved substance is from the value of M n2-1 deduced on the .~ cz riL+ 2’ assumption that tlhe property is additive.In the present experi- ments the molecular solution-volumes are given, so that allowance can be made for changes in their value when considering the effect of substitution on the molecular refractivity : hf-.-962 -1 d d+a‘ Benzoylcinchonicine was prepared by the usual Schotten-Baumann process. It crystallises in rosettes of small prisms melt- ing at 65O (Found, N=7.00. C,,Hz60,N, requires N=7*04 per cent.). m-ivitrobeizzoyZcinchon~c~neforms colourless needles melting at 119O : 0.1507 gave 11-32 C.C. N, at N.T.P. N=9*44. C,H,,O,N, requires N =9-48 per cent. 275 p-TolzLeneszclp~onykcinchonicinecrystallises from alcohol in skew tetrahedra melting at 127O. These are sparingly soluble in alcohol at 25O: 0.1560 gave 8.06 C.C.N, at N.T.P. N=6*5. C,,H,,O,N,S requires N =6.25 per cent. Picrylcinchonicine was prepared from the base and picryl chloride. It crystallises from acetone in lustrous, golden scales, melting at 180°, and is very sparingly soluble in most organic solvents : 0.1117 gave 12.70 C.C. N, at N.T.P. N=13*97. C,H,,O,N, requires N =13-86 per cent. The solutions of the above compounds were examined at 2bo. The rotatory powers were measured in 2-dcm. tubes, the densities measured in pyknometers holding about 10 c.c., and the refrac- tivities measured in a Zeiss total reflection refractometer. In the following table are collected the molecular weights, rotatory powers, refractivities and solution-volumes at 25O of the above substances : Concentration, Substance. Cinchonicine ... Solvent.

The introduction of the picryl group causes a complete change in t.he sign of the rotation, and also increases the magnitude very considerably. There do not seem to be any details of other cases of the effect of the picryl group, and it is hoped to examine further this behaviour. Adopting the electronic theory of molecular structure then, the effect of a substitution will be due partly to its disturbance of the intramolecular electrical field of force and partly to the mass of the 276 substituent.If rotatory power is due to vibrating electrons, then the relative effect of these two quantities will depend on the value of elm for t'he vibrating electron, and on the magnitudes of the changes in mass and intramolecular e1ect.rical force brought about within the molecule. This second type of change may be deducible on lines similar to those used by Flurscheim in his applications of Thiele's t-heory of partial valencies, and has already been examined to some extent by Hllditch.
