Abstract

A process for the manufacture of 1,2-dichloroethane is described, in which 1 mol of ethylene, 0.35 to 0.7 mol of chlorine, 0.7 to 1.4 mol of hydrogen chloride and 0.2 to 0.6 mol of oxygen, optionally together with inert gas, are reacted in a reaction zone containing surfaces capable of being heated and cooled, at 180.degree. to 260.degree. C. and under a pressure of 0.09 to 1.1 MPa, in the presence of a fixed bed catalyst containing copper. The process allows better utilization of the heat generated in the chlorination of ethylene.
