摘要： An allyl acetate production catalyst comprising at least (a) palladium, (b) gold, (c) a compound containing at least one element selected from copper, nickel, zinc and cobalt, (d) an alkali metal salt compound and (e) a carrier, is produced by a process comprising step 1 in which a homogeneous solution of a palladium-containing compound and a gold-containing compound is supported on a carrier by contact therewith, step 2 in which the carrier obtained in step 1 is contacted with an alkali solution for impregnation, step 3 in which the carrier obtained in step 2 is subjected to reduction treatment, and step 4 in which a compound containing at least one element selected from copper, nickel, zinc and cobalt and an alkali metal salt compound are supported onto the carrier obtained in step 3. The obtained allyl acetate production catalyst has minimal reduction in activity and improved selectivity, when used for production of allyl acetate from propylene, oxygen and acetic acid.
