Abstract
Hexachlorocyclopentadiene is produced by the use of a molten salt mixture of cuprous and cupric chloride, with the reaction effluent including the product, chlorine, hydrogen chloride, unreacted feed and organic byproduct, as well as entrained molten salt. The effluent is cooled at a temperature and pressure to effect condensation of organics, with the salt being present in the condensate. The salt is then separated from the organics for re-use in the process. Hydrogen chloride and chlorine present in the effluent are also recovered for re-use in the process.
