Document Type and Number:
WIPO Patent Application WO/2018/015363
Kind Code:
A3
Abstract:
The present invention relates to process for obtaining a catalyst composition that catalyzes a one-step synthesis of vinyl chloride from ethylene, wherein the catalyst composition comprises at least one rare earth metal. The invention relates also to a catalyst bed comprising said catalyst composition and a one-step process for the synthesis of vinyl chloride from ethylene.
