Abstract

Process for the manufacture of 1,2-dichloroethane (DCE) starting from a stream of ethane which is subjected to a catalytic oxydehydrogenation (ODH) thus producing a gas mixture containing ethylene which is then dried and conveyed to a chlorination reactor supplied with a flow of chlorine so that at least 10% of the ethylene is converted to DCE. The stream of products derived from the chlorination reactor is then conveyed to an oxychlorination reactor in which the majority of the balance of ethylene is converted to DCE.
