    摘要: This invention is a process for producing vinyl chloride from an ethylene-containing feed, oxygen, and a chlorine source in the presence of a catalyst. The process permits direct production of vinyl chloride in a single reactor system, and further permits ethane to be used as the C2 hydrocarbon feed with recycle of ethylene from the product stream to constitute the ethylene specified for the feed. This invention in another aspect concerns also a composition of matter, and a method for making the composition, wherein the composition is useful as a catalyst for the vinyl chloride process. The composition comprises a rare earth-containing material, with the proviso that the catalyst prepared therefrom is substantially free of iron and copper and with the further proviso that when cerium is present the catalyst further comprises at least one more rare earth element other than cerium.

    摘要: Ethylene is chlorinated in a reaction zone to form a product stream containing 1,2-dichloroethane, the latter being then thermally cracked in a cracking zone to form vinyl chloride. Light by-products formed during the thermal cracking step are chlorinated in a zone external and directly downstream of the reaction zone used for the preparation of the 1,2-dichloroethane product stream. The product stream leaving the chlorination reaction zone for the 1,2-dichloroethane are passed into said downstream zone so that the light by-products are chlorinated in the presence of said product stream.
