Abstract

1,256,707. Integrated chlorination process. STAUFFER CHEMICAL CO. 8 Nov., 1968 [8 Nov., 1967; 6 May, 1968], No. 49076/68. Heading C2C. Chlorinated hydrocarbons are produced in an integrated process in which (a) methane or a chlorinated methane is thermally chlorinated under substantially anhydrous conditions and at above 5 p.s.i.g., (b) the gaseous effluent from this reaction zone is passed to a partial condensation zone where chlorine-substituted materials are condensed out, and (c) the gaseous effluent from the partial condensation zone which comprises anhydrous hydrogen chloride is passed to a hydrogen chloride consuming reaction zone. The latter zone may be for the hydrochlorination of methanol or ethanol, the oxychlorination of methane, ethane, ethylene, ethylene dichloride, acetylene or benzene, or the chloromethylation of toluene.
