Claim 1

A PROCESS OF NUCLEAR SUBSTITUTION CHLORINATION OF A COMPOUND SELECTED FROM THE GROUP CONSISTING OF CHLORINE-SOLUBLE AROMATIC HYDROCARBONS HAVING AT LEAST ONE CHLORINE-REPLACEABLE HYDROGEN ATTACHED TO A NUCLEAR CARBON ATOM AND PARTIALLY NUCLEAR SUBSTITUTIVELY CHLORINATED DERIVATIVES THEREOF, WHICH COMPRISES DISSOLVING SAID COMPOUND IN AN AMOUNT OF LIQUID CHLORINE IN SUBSTANTIAL EXCESS OF THE AMOUNT TO BE REACTED WITH THE COMPOUND, SAID EXCESS FUNCTIONATING AS THE ESSENTIAL LIQUID SOLVENT MEDIUM FOR THE COMPOUND THROUGHOUT THE REACTION, MAINTAINING SAID COMPOUND AND SAID LIQUID CHLORINE IN THE PRESENCE OF A CHLORIDE CHLORRINATING CATALYST AT A PRESSURE TO KEEP ELEMENTAL CHLORINE IN THE LIQUID STATE AT THE TEMPERATURE EMPLOYED, SAID TEMPERATURE BEING ONE NOT OVER ABOUT 80* C. AND AT WHICH THE NUCLEAR SUBSTITUION CHLORINATION REACTION BETWEEN THE COMPOUND AND THE CHLORINE PROCEEDS AS ESSENTIALLY THE ONLY REACTION, AND THEREAFTER REMOVING UNCOMBINED LIQUID CHLORINE FROM THE CHLORINATED COMPOUND.
