Abstract
THE Zeitschrift fúr Chémie (No. i) contains an account of some unfinished experiments by Muck on manganous sulphide, and a note by Dr. Baumhauer, of Bonn, on the action óf aqueous hydric chloride on nitrobenzol. In the latter of these the author points out the interesting fact that dichloraniline is a principal product of the reaction. Robert Otto communicates several papers containing the results of experiments which he has performed, for the most part, with the co-operation of Eugen Dreher. The subjects of the papers áre “Mercuric Diphenyl,” under which title a tolerably exhaustive account of this body is given; “Mercuric Ditolyl,” which was not so extensively examined; “On the deportment of Dibenzyl at a high temperature” (it splits into Toluol and Toluylene); “On the transformation of hydro-phenylic sulphide into phenylic sulphide” (the mercuric derivative decomposes thus at 180°:— (C6H5)2HgS2 = (C6H5)2,S2 + Hg); “On mercuric dinaphtyl,” from which it appears that the presence of ethylic acetate is very advantageous in the usual mixture whereby the body is prepared; “On mono-ethylic and mono-methylic mercuric acetate;” and “On the preparation of organic sulphur-compounds by means of sodic hyposulphite.”—A. Geuther contributes a short article “On the volatile acids of croton oil.” He finds that the oil contains no crotonic acid, which name is consequently a misnomer. Of the two metamers, C4H6O2, he consequently designates the solid modification tetranylic, and the liquid varie/y quartenylic acid. Croton oil contains á metamer of angelic acid, for which the author proposes the name tiglink acid. —Markownikoff finds that the butylic (fermentation) alcohol, when transformed into iodide, and then, by alcoholic potash, into olefiant, furnishes with hydric iodide the tertiary pseudo-butylic iodide. —Petrieff describes solid azoxytoluide (fusing at 57°).
