Abstract

A process for the manufacture of one or more of 1,1-dichloroethylene, trichloroethylene and perchloroethylene wherein a feedstock comprising one or more chlorinated ethanes having three chlorine atoms attached to one carbon atom and 1 to 3 chlorine atoms on the other carbon atom is reacted with hydrogen in the vapour phase, preferably at a temperature of from 175 DEG C to 325 DEG C, for example 175 DEG C to 225 DEG C, in the presence of a catalyst consisting essentially of rhodium and/or iridium or compounds thereof; and chloroethanes manufactured by the process.
