METHOD FOR PRODUCING ETHYL ACETATE PRODUCTION CATALYST

Document Type and Number:

WIPO Patent Application WO/2022/070674

Kind Code:

A1

Abstract:

Provided is a method for producing an ethyl acetate production catalyst that has high producibility and exceptional catalytic performance, the catalyst being such that a heteropoly acid and/or a salt thereof is carried near the surface of a carrier. A method for producing an ethyl acetate production catalyst, the method including, in the stated order: (1) an impregnation step in which a silica carrier is impregnated with an aqueous solution of a heteropoly acid or a salt thereof, constituting 80-105 vol% of the saturation absorption capacity of the carrier, to form an impregnated body; and (2) a drying step in which the impregnated body is dried at a fixed-rate drying speed of 5-300 g H2)/kgsupcat⋅min.
