The purpose of the disclosed invention is to suppress catalyst deterioration during the production of allyl acetate by means of a reaction among oxygen, acetic acid and propylene in cases where the reaction is carried out for a long period of time, and to enable a catalyst to have a long service life. According to one embodiment of the disclosed invention, in a method for producing allyl acetate by means of a vapor-phase catalytic oxidation reaction by supplying starting material gases, namely, propylene, oxygen and acetic acid into a fixed-bed tubular reactor that is filled with a catalyst for allyl acetate production, said catalyst being composed of (a) palladium, (b) gold, (c) a fourth row metal compound containing at least one element selected from among copper, nickel, zinc and cobalt, (d) an alkali metal salt compound and (e) a carrier, two or more catalyst layers respectively containing catalysts for allyl acetate production, which are different from each other in the amount of the alkali metal salt compound (d) contained therein, are arranged within a reaction tube of the fixed-bed tubular reactor so that the amount of the alkali metal salt compound (d) supported by the carrier (e) sequentially decreases along the flowing direction the starting material gases from the inlet side toward the outlet side of the fixed-bed tubular reactor. |
