P R 0 C E E D I N (3. S OF THE CHEMICAL SOCIETY. Thursday, March 16tJh, 1911, at 8.30 p.m., Professor HAROLDB. DIXON,M.A., Ph.D., F.R.S., President, in the Chair. The PREsImwr referred to the death of Geheimrath Professor Dr. Jacobus Heinricus van’t Hoff (elected an Honorary and Foreign Member of the Society on February 2nd, 1888), who died on March 1st last. He stated that. the following telegram had been sent to Frau van’t Hoff in the name of the Society: The President, Officers, and Council of the Chemical Society deeply mourn the loss of their distinguished Honorary and Foreign Member, Professor Doctor J. H. van’t Hoff .” Messrs. Harold J. Page and F, Challenger were formally admitted Fellows of the, Society. Certificates were read for the first time in favour of Messrs.: Ernest Carr Bennison, 4, Sir John’s Road, Selly Park, Birming- ham. Richard Charles Bowden, B.Sc., 21, Rokeby Avenue, Redland, Bristol.

Atulchandra Datta, MA., Rag Mozaffar Khan, Agra. Thomas Grantham Giddy, High Street, Newcastle, N.S.W. A proposal having been made by some of the old students of Robert Wilhelm Bunsen to send a wreath toplace at the foot of his statue in Heidelberg on the occasion of the 100th anniversary of his birth (March 31st), the President stated that the Council had authorised him to sign, on behalf of the Chemical Society, the inscription attached to the wreath.The PRESIDENTread a letter addressed to the Council by Sir Edward Thorpe, stating that a committee had been formed with the object of raising a fund for the erection of a memorial t’o Joseph Priestley in his native town of Birstall, Yorkshire. Subscriptions to the fund should be sent to Mr. W. Bagshaw, at Moorfields, Birkenshaw, Leeds. Of the following papers, those marked * were read : “69. Apparatus for the maintenance of constant pressures above and below the atmospheric pressure.Application to fractional distillation.’’ By John Wade and Richard William Merriman. For pressures below t’he atmospheric pressure, air is exhausted continuously from the system by an ordinary water-pump. For pressures above the atmospheric pressure, air or other gm is forced in continuously by an automatic compressor, actuated by falling mercury. The pressure is kept constant by a regulator or compen-sator consisting of an open syphon manometer, which allows air or other gas to escape from, or enter, the system as soon as the desired excess or dirniniltion of pressure is exceeded. Various devices were also described in connexion with fractional distillation, more especially for changing the receiver without dis- turbing the pressure.DISCUSSION. The PRESIDENTrecalled the simple method used by Professor F. D. Brown twenty-five years ago for distillations under reduced pressure. The apparatus devised by the authors was obviously an instrument of great delicacy. He also congratulated the authors on having devised a convenient apparatus for keeping up a high- pressure supply of gases in which the pressure was automatically regulated. He would have found such an apparatus of great use in his work on the ignition-points of gases at varying pressures. Dr. FORSTERinquired as to the experience of the authors in connexion with bumping. At the lower pressures referred to by Dr. Wade, bumping would present much inconvenience unless checked by admission of air, and as it was the speaker’s experience that under very low pressures liquids distilled without bumping, he was interested to know whether this phenomenon accompanied dis- tillation under pressures much exceeding one atmosphere.Dr. WADEsaid that he and his colleague had experienced no difficulty with bumping; the liquids so far investigated boiled under pressures above atmospheric with perfect steadiness. The only difficulty encountered under high pressures was the great increase in the amount of air dissolved in the distillate, which escaped with considerable energy on releasing the pressure. He thought that Dr. Forster’s suggestion of distilling volatile liquids under increased pressure in order to avoid bumping was eminently practicable.“70. “The influence of water on the boiling point of ethyl alcohol at pressures above and below the atmospheric pressure.” ByJohn Wade and Richard William Merriman. The ratio of water to alcohol in the binary mixture of minimum boiling point, isolated by Young and Fortey (TI-ans.,1902, 81,1717) by systematic fractional distillation, is increased by raising, and diminished by lowering, the pressure under which the fractionation is effected. At pressures below about 80 mm., corresponding with temperatures below about 25O, ethyl alcohol and water cease to form a, binary mixture. Under these conditions, anhydrous alcohol is the most volatile phase present in ordinary spirit, and many be separated from the water to any desired extent by systemati: fractional distillation.For the same reason, although alcohol, contrary to general belief, is not appreciably hygroscopic, the percentage of water in moist alcohol is slowly increased by exposing it to air, or even by passing dry air through it. *71. c4 The interaction of aromatic disuiphides and sulphuric acid.” By William George Prescott and Samuel Smiles. When the solutions of certain disulphides in sulphuric acid are mixed with simple aromatic compounds, sulphurous acid is evolved, and unsymmetrical monosulphides are f ornied. Reasons were adduced in support of the hypothesis that preliminary fission of the dithio-system is effected by the acid, the sulphoxylic acid and mercaptan being produced : i.AroS.S*Ar+H,O -+ Ar-S-OH+ ArSH. The firsbnamed substance then yields the unsymmetrical mono-sulphide by condensation with the aromatic compound : ii. Ar-S=OH+ HAr’ =Ar*S*Ar’+H,O, whilst the mercaptan is oxidised to the disulphide (Stenhouse, Annalen, 1869, 149, ZSO), which is then available for renewed decomposition. It was further shown that the character of this reaction (i) strongly suggests that it is reversible. This hypothesis explains and correlates in a, simple manner all the known reactions of disulphides and mercaptans in sulphuric acid. *72. (( The absorption spectra of permanganates in certain solvents.” By Thomas Ralph Merton. Measurements have been made of the three least refrangible bands in the absorption spectra of potassium, calcium, barium, and zinc permanganates, in water, acetone, acetic anhydride, aceto-nitrile, methyl acetate, pyridine, methyl alcohol, ethyl alcohol, and ethylene glycol, except in those cases where the reaction between the salt and the solvent is too rapid for measurements to be made; the positions of the absorption maxima vary in different solvents, although the general character of the absorption remains the same.DISCUSSION. Mr. MERTON stated, in reply to a question, that no steps had been taken to secure large crystals of the solid solution, as this was not necessary for the purpose of observing the absorption spectrum. *73. (( The resolution of asymmetrical derivatives of phosphoric acid.” By Frederic Stanley Kipping and Frederick Challenger.This work is a continuation of that published by Luff and Kipping (Trans., 1909, 95,1993), and deals with the preparation and resolu- tion of dl-phenyb-/3-naphthyl hydrogen phosphate, PO(OPh)(O*C,,H,)*OH. Attempts to resolve this acid by the fractional crystallisation of ths salts which it forms with optically active bases were unsuccess- ful, but the I-menthylamide, PO(OPh)(O*C,,H7)*NH*C,,R,,,was easily separated into its stereochemically isomeric components. 67 DISCUSSION. Professor FRANKLANDasked what was the order of the difference in rotation of the two isomeric menthylamides. He suggested that the hydrolysis of the menthylamides might probably have been effected if hydrochloric acid instead of potash had been used.He also thought that the resolution of the acid might have been more advantageously attempted by adopting McKenzie's method of partial esterification with menthol or some other optically active alcohol, and that similarly the acid chloride might have been made to interact with an insufficient quantity of an optically active primary or secondary amine. Dr. LOWRYagreed with the authors that the isomeric amides could not be (3 and 4)0>p<C6H5(1) and (S)HO>p<C,H,(1) I(5)NHX-C7H,(3) (4and h)NX C7H7(2)' since such compounds would certainly be interconvertible. The production by a reversible action of a mere trace of one of them would, further, be sufficient to bring about the inversion or race-misation of the d-and I-forms of the other; the double bond of the first compound could be broken in such a way as to produce the OH in position 3 or 4,whilst the breaking of the double bond of the second compound could give rise to NHX in position 4 or 5; the linkings 3, 4, and 5 would, therefore, be interchangeable, and optical activity could not be expected to persist.In the case of the acids, which had resisted all attempts at resolution, it was probably impossible to isolate d-and I-forms; the addition and removal of water afforded a mechanism for interchanging the tl-(?). I-(1). linkings in ways that would almost certainly result in optical inversion and consequent' racemisat,ion. 74. '[The action of carbon dioxide in the bleaching process." By Sydney Herbert Higgins.On adding calcium chloride to lime-water, the rate of attraction of carbon dioxide from the air by the limewater is increased, and this fact probably accounts for the observation that the addition of calcium chloride to bleaching powder solution increases the bleaching efficiency of that solution. On exposing bleaching powdez solution to air, the free lime contained in the solution is deposited as calcium carbonate, and then the carbon dioxide of the air acts on the other calcium salts present in solution. It is the latter action that causes the exposed bleaching powder solution to have a high bleaching efficiency. Common salt added to sodium hype chlorite solution increases its bleaching activity, and this is also true of other neutral salts of sodium ; solutions containing equi- valent proportions of these salts have approximately the same effect in increasing the bleaching activity.Moreover, equivalent pro- portions of common salt and of calcium chloride have approximately the same effect in increasing the activity of bleaching powder solutions. These effects are probably due to the sc-called (‘neutral salt action ” and to the increased attraction of the carbon dioxide of the air by the neutral salt solutions. The results of the experi- ments and other facts (Higgins, J. SOC.Clzem. Z?zd., 1911, 30,185) do not agree with the conclusions of Taylor (Trans., 1910, 97, 2541). The author represents the action of carbon dioxide on bleaching powder by the following equations : (1) Ca(OCl), + CO,+ H,O =CaCO,+ 2HOC1.(2) 2HOC1+ CaC1, + GO2= CaCO, + 2C1, + H,O. The action represented by equation (2) is found to be reversible, and thus accounts for Taylor’s (Zoc. cit.) and the author’s results. In bleaching with bleaching-powder solution, hypochlorous acid enters into the bleaching action, and as much nascent chlorine as is supplied by the reaction represented in equation (Z), the carbon dioxide being supplied by the air. 75. ‘‘ The relation between the absorption spectra of metallic ions and their valency.” (Preliminary note.) By Cecil Reginald Crymble. A study is being made of the absorption of light by aqueous solutions of the salts of metals.A metallic ion is regarded as being “ non-absorptive” when 10 mm. of a normal solution of its salt, or a lengt>hof solution containing an equivalent amount of the metal, transmits the spectrum of t,he iron arc up to A 2300. In photographing the absorption spectra, solutions of salts of the metals, such as chlorides or sulphates, have been employed, as in these cases the acidic radicle is non-absorptive, and the absorption, if any, must be due to the metal. The metals that have been examined up to the present may be grouped into two classes, namely, “non-absorptive ” and ‘Iabsorp-tive. ” The first class, (‘non-absorptive,” contains the following metals : Li, Na, K, G1, Mg, Zn, Cd, Ba, Al, Th. The second class, I‘absorptive,” contah : Metals giving colourless solutions: Hg, TI, Sn, Pb, Sb, Bi.Metals giving coloured solutions: Cu, Ce, Mn, Fe. In addition to the metals giving coloured ions, the following metals give coloured solutions, and may be included under that head: Au, Cr. U, Co, Pt, Ti, V. When regarded from the point of view of valency, it will be observed that the first class comprises the metals of constant valency, that is, the metals which are incapable of giving two series of salts, and that the second class comprises the metals of varying valency, that is, those: metals which give two or more series of salts-the valency of a metal being determined by the fluorine or chlorine compounds which it forms. The metals which give absorptive ions may be divided into thme showing selective absorption, such as : Cu, Ce, Cr, Mn, Fe, Co, and those showing general absorption only, like : T1, Sn, Ph, Sb.The former give two series of salts in which the metal, in passing from the ‘(ous ” to the “ic ” form, increases its valency by one; for example, iron gives the chlorides FeC1, and FeC13. In the latter group the metal, when changing from the state of low valency to that of high valency, increases its valency by two, for example, tin gives the chlorides SnCl, and SnC1,. It has not yet been determined, however, whether this relation is present in all cases. The research is being continued with a view to observing the difference in absorptive power between the two forms of the same metal where the metal gives two series of salts, and to investigating the absorption spectra of the metalloids and non-metals. An attempt is also being made to trace a, relationship between the absorption spectra of the metallic ion and the position of the metal in the electrepotential series.76. The element Cu I Cu,O alkali I H,at O”.” By Arthur John Allmand. The electrode system Cu ICu,O -N-NaOE wm measured at Oo, and by combining with it the calculated value for the electrode H, I N-NaOH, the value of the E.M.P. of the cell CuI Cu,O alkali I R2 at Oo was obtained. It is one centivolt higher than the value calculated by Nernst’s theorem. 70 77. “A standard electrode with alkaline electrolyte : Hg I KgOalkali.” By Frederick George Donnan and Arthur John Allmand.The authors have extended previous work carried out with this system, and have been able closely to define three standard electrodes at 25O and Oo, namely: 13g I HgO X-KOH. Hg I HgO N-NaOH. Iig 1 HgO N/lO-NaOH. The mean errors of the values given vary between &0*00002and -+0*00011volt. 78. (‘The volatile constituents of coal. Part 11.” By Maurice John Burgess and Richard Vernon Wheeler. In continuation of their previous work, the authors have studied the action of heat on coal, paying particular attention to the composition of the gases evolved during successive stages of distilla- tion at a uniform temperature. They find that coal contains two types of compounds of different degrees of ease of decomposition.The one, the more unstable, yields the paraffin hydrocarbons and no hydrogen ;the other, decomposed with greater difficulty, yields hydrogen alone (or, possibly, hydrogen and ths oxides of carbon) as its gaseous decomposition product. The authors consider that the difference between one coal and another is determined mainly by the proportions in which these two types of compounds exist; and that the true “coal substance,” apart from the traces of sulphur compounds and other substances which mask its character, is com-pounded of the two types that behave so differently under the action of heat. It has been shown that there is considerable justifica- tion in assuming that one type of compound in coal, the vegetable origin of which is undoubted, is a degradation product of cellulose.The authors identify the ‘‘ hydrogen-yielding constituents ” with this type, and regard the “ paraffin-yielding constituents ” as being most probably derived from the resins and gums originally contained in the sap of the coal plants. They suggest that the substance which P. P. Bedson (J. SOC.Chem. Znd., 1908, 27, 147) has shown to be extracted in considerable quantity from coal by the solvent action of pyridine is compounded of the ‘‘ paraffin-yielding constituents ’’; and they therefore regard coal as a conglomerate of which the degradation products of cellulose form the base, and the changed resins and gums of the coal plants the cement. 79. ‘‘ The absorption spectra of chlorobenzene and bromobenzene as vapours, as liquids, and in solution.” By John Edward Purvis.The chief results of the investigation are : (1) that the vapours of chloro- and bromo-benzene exhibit a considerable number of narrow bands which can be divided into groups; (2) that alcoholic solutions exhibit seven diffuse bands which are comparable in appearance, and only differ in their relative positions; (3) that very thin films exhibit seven diffuse bands which are comparable with each other and with the bands of the solutions, and only differ in their relative positions. 80. I4 Orthophosphoric acid as a dehydrating catalytic agent. Part I. The condensation of acetone in presence of phosphoric acid.” By Panchanan Neogi. The author finds that in presence of ortho- and meta-phosphoric acids, acetone condenses to form mesitylene, mesityl oxide, phorone, and xylitone.A given quantity of the acid has repeatedly been used to convert fresh quantities of acetone into its condensation products. 81, L4Trialkylammonium nitrites and nitrites of the bases of the pyridine and qninoline series. Part I.” By Paiichinan Neogi. TriethLylammoniurn nitrite and pyridinium nitrite have been prepared by the interaction of silver nitrite and the hydrochlorides of the bases. The former exists both in monohydrated and anhydrous conditions, and can be sublimed unchanged under the ordinary, or under diminished, pressure. The latter is anhydrous, and is unstable, 82. Nitrites of the alkylammonium bases : ethylammonium nitrite, ‘( dimethylammonium nitrite, and trimethylammonium nitrite.” (Preliminary note.) By Prafulla Chandra RQy and Jitendra Nath Rakshit.In continuation of their previous work on methylammonium nitrite, the authors have succeeded in preparing the above members of the series by the same method, namely, interaction of silver nitrite and the corresponding chlorides of the alkylammonium bases and evaporation of the filtrate in a vacuum over sulphuric acid. Double decomposition between mercuric nitrite and the free bases in aqueous solution also furnishes the above products. It 72 is worthy of note that whilst methylammonium nitrite is a yellowish- green, crystalline substance, its homologue, ethylammonium nitrite, NH,Et=NO,, is a viscid liquid of a pale brownish-yellow colour.Dimethylammo&um nitrite, N€T,Me2-N0,, is a limpid, pale yellow liquid. Trimeth ylamntonizrm nitrite, NHMe3*NO2, on the other hand, is a pale green, crystalline solid. 83. (‘Isomeric monothiophosphates,” By William Gidley Emmett and Humphrey Owen Jones The isomeric a-and P-methyl monothiophosphates, PS(OMe), and PO(OMe),*SIMe, have been examined in the hope that on saponification they would yield isomeric sodium monothiophosphates. Two diff went sodium dimethyl monothiophosphates are formed by the ac&n of sodium methoxide on the esters, and a disodium methyl a-thiophosphate was obtained by saponification of the a-ester with sodium hydrosulphide, but no isomeric trisodium thiophosphates have been isolated.The interactions of the esters and their derivatives with metallic salts have been examined. Both a-and &esters react with methyl iodide to give trimethyl- sulphonium iodide and a methyl phosphate. 84 L6 The absorption spectra of chlorobenzene, the dichlorobenzenes, and the chlorotoluenes.” By Edward Charles Cyril Baly. The absorption spectra of chlorobenzene, the three dichloro-benzenes, and the chlorotoluenes have been observed with more efficient apparatus than was possible in the earlier work (Tmns., 1905, 87, 1332, 1355). Some new absorption bands have been detected. 85. Chemical constitution and hypnotic action. Acid amides and products of the condensation of malonamides and malonic esters.” By Frederic George Percy Remfry.b Acid amides are known to possess hypnotic properties to a certain extent. A number of compounds were prepared, in which one hydrogen atom of the amido-group was replaced by various radicles in the hope of increasing the hypnotic power of the acid amide. Such substances as cinnamoyl -p -aminoacetophenone (m. p. 204-205O), dicinnamoylcarbamide (m. p. 246O), and a-bromoiso- vnleryl-p-aminoacetophenone (m. p. 113-114°), in which both the acid amide and the substituent, when uncombined, have some 73 narcotic properties, were found to be quite inactive. By condens- ing ethyl malonate with malonamide, rnalonylmalonamide, CO NH CO CH,<CO.&l H.CO>CH, (m. p. 252-253O), was obtained.Two alkyl groups can be attached to one of the ‘‘quaternary ” carbon atoms and one to the other; the product, however, although somewhat resembling diethyl-barbituric acid, a very strong hypnotic, was quite inactive. It was found that when a monoalkylmalonamide was condensed with ethyl nialonate or ethyl alkylmalonate, a diketotetrahydropyrimidins N--GO was formed of the type CR<NB,pO>CHR.t Ethyl monoalkyl- malonates, ethyl dimethyl- and methylethyl-malonates (in part) condensed with malonamide to the eight-membered ring as above, but ethyl methylethy1ma.lonate (in part) and the higher dialkyl- malonates give a different condensation product with malonamide, the empirical formuke of which alone have been determined. None of these compounds was physiologically active, nor was ethylenebis-5-propylbarbituric acid, (which does not melt at 3OOc).Dial~ylmalonylbenziclinesof the CO*NH*Y,H,type CR2<C@NH.C6H, were too insoluble to be of any use, whilst isobutyl allophanate, NH,*CO*N€I*CO,-CH,.CRCMe, (m. p. 178-179O), and tert.-amyl allophanate, NH2*CO=NH*C0,*CEtMe, (m. p. 151--152O), were inactive, the hypnotic properties of the respective alcohols being completely neutralised when combined with allophanic acid. 86. ‘‘p-Benzoyloxybenzaldehgde.” By Frank George Pope. The benzoyl derivative of p-hydroxybenzaldehyde was prepared in 1893 by Kopp (Annalen, 277, 350) by means of the Schotten- Baumann reaction in 10 per cent. potassium hydroxide solution. The melting point of the compound as obtained in this manner is given as 72O.Since an alkali hydroxide solution of such concen-tration might possibly affect the course of the reaction, it seemed better to carry out the operation in pyridine solution, and conse- quently 12 grams of the aldehyde were dissolved in 90 C.C. of pyridine and 14 grams of benzoyl chloride added to the solution. The mixture was well shaken for half an hour, and then poured into 300 C.C. of water, the precipitate collected, well washed, and 74 cryetallised from alcohol, when it separated in small, colourless needles, melting sharply at. 95O. As such a considerable difference was found in the melting points, a sesond preparation was made, using N-potassium hydroxide solution.The recrystallised product in this case was also found to melt at 95O, and a mixture of the two specimens melted at 93O. Kopp'a specimen thus seems to have been impure, and a few deriva- tives were therefore prepared in order to characterise the substance. p-Benzoyioxybenzaldehyde yielded the following numbers on analysis : 0.1110 gave 0.3026 CO, and 0.0480 H20. C =74.35 ;H =4-80. C,4E1003 requires C =74.34 ;H =4-43 per cent.

P-BenzoyZo~~benzonitrile,C,.H,-CO*O*C,H4*CN, was obtained by boiling 5 grams of the oxime with 25 grams of acetic anhydride under reflux for two hours.The product was poured, with cun-tinual stirring, into 500 C.C. of water, when it set to a solid mass. This was collected, washed, and finally crystallised from dilute alco'hol, from which it separates in colourless needles, melting at 95O : 0.1304 gave 0.3610 CO, and 0.0476 H,O.
