Abstract
In the oxychlorination of a hydrocarbon, the ratio of hydrocarbon feed to hydrogen chloride feed is maintained within set limits in response to changes in the concentration of aqueous hydrogen chloride recovered from the oxychlorination effluent. The concentration of aqueous hydrogen chloride recovered from the effluent may be determined either by conductivity and/or density.
