Abstract
1,256,708. Chlorination process. STAUFFER CHEMICAL CO. 8 Nov., 1968 [8 Nov., 1967; 6 May, 1968], No. 29882/71. Divided out of 1,256,707. Heading C2C. Methyl chloride is produced by reacting hydrogen chloride and methanol in a catalytic reaction zone at elevated temperature and pressure, the hydrogen chloride being employed in stoichiometric excess and the catalytic zone containing an unmodified activated alumina or zinc chloride catalyst. The hydrogen chloride may be produced by the thermal substitution chlorination of methane or a chlorinated methane under substantially anhydrous conditions and at above 5 p.s.i.g., and passing the reaction products to a partial condensation zone to condense chlorine-substituted materials.
