ABSTRACT:
Two byproducts of the chlorine-consuming industry, weak hydrochloric acid and chlorine-containing organic wastes, are utilized in the production of chlorinated organics, preferably hydrocarbons, by oxychlorination. The chlorine-containing organic waste is burned, liberating its chlorine content as HCl, its heat content being used to evaporate weak hydrochloric acid by direct contact with the combustion gases, and the mixture is passed, with organics, preferably hydrocarbons, and air, over an oxychlorination catalyst of the Deacon type. The chlorinated organic, preferably hydrocarbon, is recovered by conventional means.
