Abstract
LONDON Chemical Society, November 4.—Prof. H. E. Roscoe in the chair.—The following papers were read:—On the compounds of vanadium and sulphur, by E. W. E. Kay. The author shows that the products obtained by Berzeilua are oxy-compounds, that the substance obtained by Berzelius in the dry way is a true trisulphide of vanadium V2S3; the disulphide and pentasulphide have also been prepared and are described in the present paper.—On the atmospheric oxidation of phosphorus and some reactions of ozone and peroxide of hydrogen, by C. T. Kingzett. The author concludes that in the above oxidation both ozone and peroxide of hydrogen are formed, the former passes on in the current of air, the latter remains in the water in which the phosphorus is oxidised. In several experiments the proportion of peroxide of hydrogen to the ozone formed was as I to 2.—On the action of zinc ethyl on benzoylic cyanide, by E. Frankland and D. A. Louis. The product of this reaction, an amber-coloured jelly, was first decomposed and then extracted with alcohol, about 3 per cent, of a substance C24H19NO2, named provisionally benzcyanidin, crystallising in colourless needles, was obtained. Besides this body an unstable substance was obtained which could not be purified, but which on oxidation with bichromate gave propiophenone C9H10O.—On the action of zinc-ethyl on cyanogen, by E. Frankland and C. C. Graham. The product of this reaction was a solid mass, which on heating to 120° yielded a colourless liquid which was propionitrile C3H5N., the other product of the reaction being zinc cyanide.—On bismuth and bismuth compounds, by M. M. P. Muir, G. B. Hoffmeister, and C. E. Robbs. The relative stabilities towards heat and reducing agents of the oxides, and towards heat of the hydrates are discussed, also the action of chlorine and bromine on the oxides. An attempt is made to give structural formula for these bodies, in which bismuth is trivalent.—On the colour-properties and relations of the metals copper, nickel, cobalt, iron, manganese, and chromium, by T. Bayley. The author has carefully compared the colours of solutions of salts of the above metals and various mixtures thereof, and especially those mixtures which yield colourless or neutral grey solutions.—Action of diazo-naphthalin on salicylic acid, by Percy Frankland.—On the basic sulphates of iron, by Spencer Pickering.—Fourth report on researches in chemical dynamics, by C. R. A. Wright, E. H. Rennie, and A. E. Menke.—On some naphthalin derivatives, by C. E. Armstrong and N. C. Graham.—On acetylorthoamidobenzoic acid, by P. P. Bedson and A. J. King.
