Abstract
1,141,370. Trichloroethylene and perchloroethylene. HOOKER CHEMICAL CORP. 25 Aug., 1966 [27 Aug., 1965], No. 38223/66. Heading C2C. Trichloroethylene and perchloroethylene are produced by reacting acetylene, a chlorinating agent and an oxygen-containing gas in the presence of an oxychlorination catalyst at a temperature of 170‹ to 450‹ C. and separating the polychlorinated ethylenes produced from other gases effluent from the reaction zone, and if desired recycling the latter to the reactor. Dichloroethylenes and various polychlorinated ethanes are obtained as by-products. The proportion of perchloroethylene produced may be increased by controlling the degree of chlorination and by recycling unreacted and lower chlorinated products. Specified catalysts, which may be in the form of a fixed or fluidized bed, are complexes comprising a major proportion of alumina and a minor proportion of a halide of a metal having a variable valence, e.g. copper, scandium, titanium, vanadium, nickel, chromium, cobalt, iron, uranium, silver and gold.
