Abstract of the Disclosure The production of undesirable 1,1,2-trichloroethane and unsym-tetrachloroethane during the production of perchloro- ethylene is eliminated or essentially eliminated by an improved oxychlorination reaction. The oxychlorination reaction is carried out in the presence of a copper chloride-alkali metal chloride catalyst mixture deposited on a microspheroidal activated alumina carrier having an average particle size of between about 40 and about 70 microns and a surface area of at least about 100 m2/g with the copper chloride and alkali metal chloride being present on the carrier in a weight ratio of at least about 1.2 to 1. Reaction parameters, including, e.g., time, temperature and pressure, are controlled to produce a reaction product containing perchloro- ethylene and trichloroethylene, and the reaction product is free from 1,1,2-trichloroethane and unsym-tetrachloroethane.
