Abstract
The invention is an improved catalyst and process for the manufacture of vinyl chloride from ethylene dichloride. Specifically, the invention is an improved catalyst for the catalyzed dehydrohalogenation of ethylene dichloride in the presence of oxygen. The catalyst comprises a rare earth metal chloride on a zeolite. The catalyst and process enables one to conduct the dehydrohalogenation (or cracking) operation at significantly lower temperatures than employed using a thermal process, without the coking problems observed in such cracking processes.
