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.
