Abstract 1. A CYCLIC PROCESS FOR THE PRODUCTION OF PURIFIED ETHYLENE DICHLORIDE WHICH COMPRISES: (3) MAINTAINING A LIQUID BODY OF ETHYLENE DICHLORIDE CONTAINING HIGHLY CHLORINATED SUBSTITUTION REACTION PRODUCTS AS IMPURITIES IN A VERTICALLY DISPOSED REACTION ZONE; (B) INTODUCING ETHYLENE AND CHLORINE AS REACTANTS, WHEREIN THE ETHYLENE IS PRESENT IN AT LEAST STOCIHIOMETRIC AMOUNTS REQUIRED TO REACT WITH THE ADDED CHLORINE TO PREPARE ETHYLENE DICHLORIDE, INTO SAID LIQUID BODY AT A POINT NEAR THE BOTTOM OF THE VERTICALLY DISPOSED REACTION ZONE TO EFFECT REACTION AND PRODUCTION OF ADDITIONAL ETHYLENE DICHLORIDE, SAID REACTION BEING EXOTHERMIC, THEREBY HEATING THE LIQUID BODY NEAR THE BOTTOM OF THE VETICALLY DISPOSED REACTION ZONE AND INDUCING THE HEATED LIQUID BODY TO RISE IN THE VERTICALLY DISPOSED REACTION ZONE, SAD ETHYLENE AND CHLORINE GAS FEED INTRODUCED INTO THE LIQUID BODY NEAR THE BOTTOM THEREOF ALSO INDUCING UPWARD MOVEMENT OF THE LIQUID BODY IN THE VERTICALLY DISPOSED REACTION ZONE; (C) FLOWING THE UPWARDLY MOVING LIQUID BODY FROM THE TOP OF THE VERTICALLY DISPOSED REACTION ZONE THROUGH AN UNINTERRUPTED PASSAGEWAY INTO THE TOP OF A VERTICALLY DISPOSED EXTERNALLY COOLEC HEAT EXTRACTION ZONE WHEREIN THE LIQUID BODY IS COOLED; (D) FLOWING THE COOLED LIQUID BODY FROM THE BOTTON OF THE ZONE OF HEAT EXTRACTION THROUGH AN UNINTERRUPTED PASSAGEWAY TO THE BOTTOM OF THE VERTICALLY DISPOSED REACTION ZONE, THEREBY MAINTAINING CIRCULATION OF THE LIQUID BODY BETWEEN THE ZONES WITHOUT MECHANICAL MEANS; (E) MAINTAINING THE TEMPERATURE IN THE ZONE OF REACTION AT THE BOILING POINT OF THE CIRCULATING LIQUID BODY TO GENERATE VAPORS OF ETHYLENE DICHLORIDE; (F) RELEASING EVELVED VAPORS FROM THE ZONE OF VAPOR GENERATION; (G) SUBJECTING THE ETHYLENE DICHLORIDE VAPORS TO REACTFICATION, CONDENSEING VAPORS FROM SAID RECTIFICATION AND RETURNING A PORTION OF SAID CONDENSED ETHYLENE DICHLORIDE TO THE RECTIFICATION ZONE; (H) RECOVERING PURIFIED ETHYLENE DICHLORIDE FROM THE CONDENSATION ZONE; AND (I) WITHDRAWING A MINOR AMOUNT OF CIRCULATING LIQUID BODY CONTAINING IMPURITIES FRROM THE CIRCULATING ZONE.
A CYCLIC PROCESS FOR THE PRODUCTION OF PURIFIED ETHYLENE DICHLORIDE WHICH COMPRISES: (3) MAINTAINING A LIQUID BODY OF ETHYLENE DICHLORIDE CONTAINING HIGHLY CHLORINATED SUBSTITUTION REACTION PRODUCTS AS IMPURITIES IN A VERTICALLY DISPOSED REACTION ZONE; (B) INTODUCING ETHYLENE AND CHLORINE AS REACTANTS, WHEREIN THE ETHYLENE IS PRESENT IN AT LEAST STOCIHIOMETRIC AMOUNTS REQUIRED TO REACT WITH THE ADDED CHLORINE TO PREPARE ETHYLENE DICHLORIDE, INTO SAID LIQUID BODY AT A POINT NEAR THE BOTTOM OF THE VERTICALLY DISPOSED REACTION ZONE TO EFFECT REACTION AND PRODUCTION OF ADDITIONAL ETHYLENE DICHLORIDE, SAID REACTION BEING EXOTHERMIC, THEREBY HEATING THE LIQUID BODY NEAR THE BOTTOM OF THE VETICALLY DISPOSED REACTION ZONE AND INDUCING THE HEATED LIQUID BODY TO RISE IN THE VERTICALLY DISPOSED REACTION ZONE, SAD ETHYLENE AND CHLORINE GAS FEED INTRODUCED INTO THE LIQUID BODY NEAR THE BOTTOM THEREOF ALSO INDUCING UPWARD MOVEMENT OF THE LIQUID BODY IN THE VERTICALLY DISPOSED REACTION ZONE; (C) FLOWING THE UPWARDLY MOVING LIQUID BODY FROM THE TOP OF THE VERTICALLY DISPOSED REACTION ZONE THROUGH AN UNINTERRUPTED PASSAGEWAY INTO THE TOP OF A VERTICALLY DISPOSED EXTERNALLY COOLEC HEAT EXTRACTION ZONE WHEREIN THE LIQUID BODY IS COOLED;
