Abstract
(EN) Provided is a method for manufacturing a catalyst with which it is possible to manufacture vinyl acetate at a remarkably high selection rate while ensuring a high catalyst activity. A method for manufacturing a catalyst for manufacture of vinyl acetate containing a carrier, copper, palladium, gold, and an acetate, the method comprising in the following order: step 1) a step for impregnating the carrier with an alkaline solution; step 2) a step for contact-impregnating the carrier with a solution containing a compound containing copper, a compound containing palladium, and a compound containing gold; step 3) a step for performing reduction treatment; and step 4) a step for causing the carrier to carry the acetate.
