Abstract

The invention concerns a process for preparing 1,2-dichloroethane (EDC) by feeding chlorine and ethylene into circulated EDC which contains a catalyst. A partial stream of the reaction mixture is fed to a flash vaporization system and the vaporized EDC is separated from its light volatile components which are returned to the reaction.
