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.

Process for the preparation of trichloroethylene

A method for preparing hydrogen chloride resulting from chlorination reactions for use in the ethyleneoxichlorination process by reacting the chlorine contained in the hydrogen chloride with ethylene in the gaseous phase in the presence of carrier catalysts based on an iron-free transition metal chloride having an activity profile which increases in the flow direction, while maintaining the space-flow rates relatively high and the residence time of the gas in the reactor short. After discharge of the reaction product from the reactor the product is subjected to partial condensation advantageously performed in several steps.
