Claims
- 1. In the method of recovering benzene and chlorine from a mixture of isomeric hexachlorocyclohexanes obtained as a waste product in the manufacture of lindane, which comprises reacting said mixture with zinc and subjecting the resulting zinc chloride to electrolysis, the improvement which resides in that the reaction is performed with a solution of said mixture of isomeric hexachlorocyclohexanes in a substantially water-immiscible organic solvent which is stable under the reaction conditions in the cathode compartment of a diaphragm electrolysis cell, and the zinc is produced at the cathode of said cell.
- 2. The method of claim 1, where the zinc chloride content of the catholyte of said electrolysis cell is between 30 and 60% by weight.
- 3. The method of claim 1, where the zinc chloride content of the catholyte of said electrolysis cell is about 50% by weight.
- 4. The method of claim 1, where the reaction temperature is above about 95.degree. C.
