ANTIPOV. 23 Oct., 1969, No. 51882/69. Heading C2C. Polychloroethylenes are prepared by dehydrochlorinating a polychloroethane in the vapour phase at 250‹ to 500‹ C. under a pressure of 2 to 30 atmospheres in the presence of a reaction initiator, e.g. oxygen, a halogen, or a compound such as hexachloroethane which is capable of liberating free radicals under the reaction conditions. The initiator is preferably present in an amount of from 0.2 to 0.9% by weight based on the weight of the polychloroethylene feed. Examples describe the preparation of vinylidene chloride and cis- and transdichloroethylenes from trichloroethane, and the preparation of trichloroethylene from tetrachloroethane. |
