Romer concludes that acetylene like ethane, ethy 1 Ann. 226, 153. 2 Ann. 233, 215 and 184, (3) Ann. Chitn. Phys. 16,473.--Carb. d'Hyd. vol. I. 3 Ber. 18, 2272. lene, and carbon monoxide are analogous in their action towards chlorine, and like hydrogen, will explode with chlorine only under the influence of the action of rays of light. In 1872 Berthelot and Jungfleisch effected the chlorination of acetylene by means of antimony pentachloride. This compound absorbs the gas with the formation of a substance corresponding to the formula C2H2SbCl5, which separates in well defined crystals. With water, decomposition takes place and on heating, a mixture of di-and tetra-chlorides of acetylene distills over. When the crystalline compound is heated with an excess of antimony pentachloride, pure tetrachlorethane is obtained. In the distillation explosions very frequently occurred. There is also much danger in passing acetylene into heated antimony pentachloride. The reactions of this method of preparing the chlorides of acetylene were represented by the authors by the following equations: C2H2 + SbCl5=C2H2-SbCl5. C2H2SbCl5 = C2H2Cl2 + SbCl3. C2H2SbCl5 + SbCl5=C2H2Cl4 + 2SbCl3 Sabanejeff in 1883 repeated these experiments of Berthelot and Jungfleisch1 in order to obtain the dichloride of acetylene, and the intermediate compound C2H2-SbCl0, but with little success. The absorption of the gas took place with great difficulty, and with very little evolution of heat. Shaking the contents 1 Ann. 216, 257. of the flask often gave rise to an explosion. SabanejefF could not obtain the crystalline compound...
