Abstract
Hydrogen chloride and oxygen are contacted with a molten mixture of cuprous and cupric chloride in a oxidation reaction zone to enrich the cupric chloride content of the melt, and the melt introduced into a dechlorination zone wherein gaseous chlorine is removed from the melt. The oxidation reactor is operated at a pressure higher than the dechlorination reactor, and molten salt circulation rates are controlled in a manner such that the cupric chloride content and temperature of the salt introduced into the dechlorination reaction zone are higher than the cupric chloride concentration and temperature of the melt introduced into the oxidation reactor.
