Claim 1

IN A CYCLIC PROCESS FOR THE SIMULTANEOUS PRODUCTION OF TRICHLOROETHYLENE AND PERCHLOROETHYLENE, THE STEPS WHICH COMPRISE SIMULTANEOUSLY INTRODUCING CHLORINE GAS, ACETYLENE AND TRICHLOROETHYLENE INTO A CHLORINATION ZONE SUBSTANTIALLY FILLED WITH A MIXTURE OF TETRACHLOROETHANE AND PENTACHLOROETHANE IN THE LIQUID PHASE, SAID ACETYLENE BEING INTRODUCED AT THE MAXIMUM RATE COMPATIBLE WITH NO FREE ACETYLENE REACHING THE TOP OF THE CHLORINATION ZONE AND SAID CHLORINE GAS BEING INTRODUCED AT A RATE SLIGHTLY IN EXCESS OF THAT STOICHIOMATRICALLY REQUIRED FOR THE ADDITIVE CHLORINATION OF BOTH SAID ACETYLENE AND SAID TRICHLOROETHYLENE, THEREBY FORMING TETRACHLOROETHANE AND PENTACHLOROETHANE, WITHDRAWING THE REACTION MIXTURE FROM THE CHLORINATION ZONE SUBJECTING SAID MIXTURE TO DEHYDROCHLORINATION, WHEREBY TO OBTAIN A MIXTURE OF TRICHLOROETHYLENE AND PERCHLOROETHYLENE, SEPARATING SAID TRICHLOROETHYLENE FROM SAID PERCHLOROETHYLENE, WITHDRAWING A PORTION OF SAID TRICHLOROETHYLENE AND RETURNING THE REMAINING PORTION OF SAID TRICHLOROETHYLENE TO SAID CHLORINATION ZONE.
