Abstract

In the process, a copper/rhodium catalyst impregnated with 0.1 to 10.0% by weight, based on the total weight of active charcoal catalyst support and active components, of a water-soluble phosphonium halide is employed for the preparation of trichloroelethylene from perchloroethylene and hydrogen.
