Manufacture of chlorinated hydrocarbons

Claim 1

THE METHOD WHICH COMPRISES ESTABLISHING A MOVING BED OF A SOLID REACTION MASS COMPRISING AN INERT CARRIER AND A CHLORIDE OF COPPER, MOVING THE ENTIRE SAID BED AT A SUBSTANTIALLY UNIFORM RATE SUCCESSIVELY THROUGH A ZONE IN WHICH A PART OF THE CUPROUS CHLORIDE IS OXIDIZED TO CUPRIC OXYCHLORIDE BY REACTION WITH A GAS CONTAINING FREE OXYGEN, THENCE THROUGH ANOTHER ZONE IN WHICH THE CUPRIC OXYCHLORIDE PORTION OF THE REACTION MASS REACTS WITH HYDROGEN CHLORIDE AND IS CONVERTED TO CUPRIC CHLORIDE, THENCE THROUGH ANOTHER ZONE IN WHICH THE REMAINING CUPROUS CHLORIDE PORTION OF THE REACTION MASS REACTS WITH OXYGEN AND HYDROGEN CHLORIDE AND IS THEREBY CONVERTED TO CUPRIC CHLORIDE, THE TEMPERATURE OF THE SOLID REACTION MASS BEING INCREASED IN EACH SAID ZONE DUE TO THE EXOTHERMIC REACTION THEREIN, THEN MOVING THE SUPPORTED CUPRIC CHLORIDE MASS THROUGH A FINAL ZONE IN WHICH IT REACTS WITH A VOLATILE AND CHLORINATABLE FEED, MATERIAL AND IS REDUCED TO CUPROUS CHLORIDE, AND FINALLY RETURNING THE SOLID REACTION MASS AT THE SAME SUBSTANTIALLY UNIFORM RATE TO THE FIRST SAID ZONE OF N REDUCED TEMPERATURE, WHILE PASSING COUNTERCURRENT TO PORTION OF SAID MOVING BED THE CHLORINATABLE FEED INTRODUCED INTO THE LAST ZONE AND INITIALLY CONSISTING OF A MATERIAL SELECTED FROM THE GROUP CONSISTING OF THE READILY VOLATILE HYDROCARBONS AND THEIR VOLATILE AND LESS THAN FULLY CHLORINATED CHLORINE REATION PRODUCTS, AT A RATE TO AVOID SOLIDS TURBULENCE IN THE REACTOR ZONES AND TO REDUCE TH CUPRIC CHLORIDE IN THE LAST AND HOTTEST ZONE TO CUPROUS CHLORIDE THE REACTON PRODUCTS FROM SAID HOTTEST ZONE BEING CONVEYED THENCE AND INTRODUCED IN COUNTERCURRENT FLOW TO THE ZONE WHEREIN SAID MASS CONTAINS A MIXTURE OF CUPROUS CHLORIDE AND CUPRIC OXYCHLORIDE; RECOVERING CHLORINATED HYDROCARBON FROM THE EFFLUENT FROM SAID ZONE; AND, BETWEEN THE TWO ZONES EMPLOYED FOR CONTACT BETWEEN THE HYDROCARBON AND THE SOLID REACTION MASS, CAUSING HYDROGEN CHLORIDE AND A GAS CONTAINING FREE OXYGEN TO FLOW COUNTERCURRENT TO SAID MASS, CONVERTING THE COPPER VALUES THEREIN SUBSTANTIALLY COMPLETELY TO CUPRIC CHLORIDE.

Claim 2

THE METHOD WHICH COMPRISES ESTABLISHING A MOVING BED OF A SOLID REACTION MASS COMPRISING AN INERT CARRIER AND A CHLORIDE OF COPPER, MOVING THE ENTIRE SAID BED AT A SUBSTANTIALLY UNIFORM RATE SUCCESSIVELY THROUGH A ZONE IN WHICH A PART OF THE CUPROUS CHLORIDE IS OXIDIZED TO CUPRIC OXYCHLORIDE BY REACTION WITH A GAS CONTAINING FREE OXYGEN, THENCE THROUGH ANOTHER ZONE IN WHICH THE CUPRIC OXYCHLORIDE PORTION OF THE REACTION MASS REACTS WITH HYDROGEN CHLORIDE AND IS CONVERTED TO CUPRIC CHLORIDE, THENCE THROUGH ANOTHER ZONE IN WHICH THE REMAINING CUPROUS CHLORIDE PORTION OF THE REACTION MASS REACTS WITH OXYGEN AND HYDROGEN CHLORIDE AND IS THEREBY CONVERTED TO CUPRIC CHLORIDE, THE TEMPERATURE OF THE SOLID REACTION MASS BEING INCREASED IN EACH SAID ZONE DUE TO THE EXOTHERMIC REACTION THEREIN, THEN MOVING THE SUPPORTED CUPRIC CHLORIDE MASS THROUGH A FINAL ZONE IN WHICH IT REACTS WITH A VOLATILE AND CHLORINATABLE FEED, MATERIAL AND IS REDUCED TO CUPROUS CHLORIDE, AND FINALLY RETURNING THE SOLID REACTION MASS AT THE SAME SUBSTANTIALLY UNIFORM RATE TO THE FIRST SAID ZONE OF N REDUCED TEMPERATURE, WHILE PASSING COUNTERCURRENT TO PORTION OF SAID MOVING BED THE CHLORINATABLE FEED INTRODUCED INTO THE LAST ZONE AND INITIALLY CONSISTING OF A MATERIAL SELECTED FROM THE GROUP CONSISTING OF THE READILY VOLATILE HYDROCARBONS AND THEIR VOLATILE AND LESS THAN FULLY CHLORINATED CHLORINE REATION PRODUCTS, AT A RATE TO AVOID SOLIDS TURBULENCE IN THE REACTOR ZONES AND TO REDUCE TH CUPRIC CHLORIDE IN THE LAST AND HOTTEST ZONE TO CUPROUS CHLORIDE THE REACTON PRODUCTS FROM SAID HOTTEST ZONE BEING CONVEYED THENCE AND INTRODUCED IN COUNTERCURRENT FLOW TO THE ZONE WHEREIN SAID MASS CONTAINS A MIXTURE OF CUPROUS CHLORIDE AND CUPRIC OXYCHLORIDE; RECOVERING CHLORINATED HYDROCARBON FROM THE EFFLUENT FROM SAID ZONE; AND, BETWEEN THE TWO ZONES EMPLOYED FOR CONTACT BETWEEN THE HYDROCARBON AND THE SOLID REACTION MASS, CAUSING HYDROGEN CHLORIDE AND A GAS CONTAINING FREE OXYGEN TO FLOW COUNTERCURRENT TO SAID MASS, CONVERTING THE COPPER VALUES THEREIN SUBSTANTIALLY COMPLETELY TO CUPRIC CHLORIDE.
