Process for preparation of allyl acetate.

摘要

A catalyst prepared by (a) impregnating a catalyst carrier with an aqueous solution of a palladium salt and a salt of at least one metal selected from the group consisting of copper, lead, ruthenium and rhenium in an amount corresponding to 90 to 95% of the water absorption of the carrier, (b) treating the impregnated carrier with an aqueous solution of an alkali metal salt in an amount corresponding to 120 to 500% of the water absorption of the carrier to precipitate water-insoluble compounds of palladium and at least one metal selected from the group consisting of copper, lead, ruthenium and rhenium on the carrier, (c) treating the metal compounds-deposited carrier with a reducing agent to convert the compounds to the corresponding metals, and (d) further supporting an alkali metal acetate on the carrier, had a high catalytic activity for the reaction of forming allyl acetate by reacting propylene, acetic acid and oxygen in the gas phase, and the selectivity to allyl acetate is very high and the life of this catalyst is long.
