Selective oxidation of acetylenes

摘要

Acetylenic compounds are selectively removed from hydrocarbon mixtures containing same by oxidation in the presence of a copper-manganese-rare earth metal-zinc aluminate catalyst. In one embodiment, acetylenic compounds are selectively removed from a conjugated diene mixture containing same by contacting oxygen and the mixture with a catalyst of zinc aluminate promoted with copper, manganese, and a rare earth metal under oxidizing conditions.
