METHOD OF PRODUCING VINYL ACETATE

摘要

A method of producing vinyl acetate by reacting ethylene, oxygen and acetic acid in vapor phase with the use of a porous, particulate catalyst which comprises 0.3 to 3.0 weight % of palladium metal, 0.0157 to 1.8 weight % of gold metal and 1 to 30 percent by weight of an alkali metal acetate, based on the weight of the carrier, which are supported on carrier particles such that (1) at least 90% by weight each of the supported palladium and gold is distributed within the outer 30% of the particle radius and (2) the proportion of gold to palladium ranges from 5 to 60% by weight based on the total weight of gold and palladium.
