INVENTION: PRODUCTION OF ETHYLENE DICHLORIDE FROM ETHANE INVENTORS: BRUCE E. KURTZ, EDMUND W. SMALLEY, WALTER E. SONNERMAN and JOHN R. VAN ATTA ABSTRACT OF THE DISCLOSURE A process is disclosed for the production of ethylene dichloride from ethane. Ethane is introduced into an autather- mic (self-sustaining) cracking zone together with controlled poroportions of chlorine and oxygen. The autothermic cracking zone is maintained at a temperature above about 700°C. but below 1000°C. for a sufficient time to convert from about 20 to 95 percent of the ethane having about 96 to 74 percent ethylene yield, respectively, based on the converted ethane. The reaction mixture, containing predominant y ethylene and hydrogen chloride, is quenched with a volatile liquid. The quenched mixture is passed, together with oxygen, into a catalytically activated oxyhydrochlorination zone to convert the ethylene, hydrogen chloride and oxygen to ethylene di chloride, If vinyl chloride is desired as a product, part or all of the produced ethylene dichloride is passed to a second cracking zone for conversion to vinyl chloride pro- duct and hydrogen chloride. The hydrogen chloride produced is recycled to the oxyhydrochlorination zone. Ethylene di- chloride, vinyl chloride or mixtures of ethylene dichloride and vinyl chloride can be recovered as product, with sub stantially complete utilization of the hydrogen chloride produced.
