Abstract:
1. A process for production of an allyl acetate production catalyst comprising (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, the process being characterized by comprising the following steps: Step 1: A step of preparing a homogeneous solution of a palladium-containing compound and a gold-containing compound, and contacting the solution with the (e) carrier to support both compounds on the carrier; Step 2: A step of contacting (f) an alkali solution with the carrier obtained in step 1 for impregnation; Step 3: A step of reduction treatment of the carrier obtained in step 2; Step 4: A step of supporting (c) a compound containing at least one element selected from copper, nickel, zinc and cobalt and (d) an alkali metal salt compound on the carrier obtained in step 3, and wherein the amount of (b) gold is 2.0-3.5 parts by mass with respect to 100 parts by mass of the (a) palladium.
