Abstract
All or a portion of chlorinated hydrocarbons convertible to trichloroethylene and/or perchloroethylene by chlorination, dehydrochlorination or dehydrogenation and optionally also dechloroination are recovered from a C.sub.2 chlorinated hydrocarbon waste stream and contacted with a molten mixture of, for example, cuprous chloride, cupric chloride and copper oxychloride and hydrogen chloride and/or chlorine, to produce an effluent which contains as reaction product trichloroethylene and/or perchloroethylene. Chlorinated components in the waste stream not contacted with the molten mixture can be burned and the chlorine values used to enrich the chlorine content of the melt.
