Abstract
Perchloroethylene and hydrogen chloride are made by noncatalytic thermal chlorination of hydrocarbons and/or their partially chlorinated derivatives by reacting them with chlorine in the presence of hydrogen and carbon tetrachloride as a reactive diluent, under conditions which maximize consumption of carbon tetrachloride and minimize the production of heavy ends, such as hexachlorobenzene and other tarry products.
