Abstract

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.

Description

technical field

[0001] The invention relates to a method for producing a catalyst for producing allyl acetate and a method for producing allyl acetate using the catalyst. In particular, the present invention relates to a method for producing a catalyst for the production of allyl acetate using propylene, oxygen and acetic acid as raw materials, the catalyst comprising (a) palladium, (b) gold, (c) containing A compound of at least one element selected from copper, nickel, zinc and cobalt and (d) an alkali metal salt, and the present invention also relates to a method for producing allyl acetate using the catalyst. Background technique

[0002] Allyl acetate is an important industrial raw material used in the production of solvents and allyl alcohol.

[0003] The allyl acetate production method includes a gas-phase reaction and a liquid-phase reaction using propylene, acetic acid, and oxygen as raw materials. Known catalysts widely used in such reactions contain palladium as...
