Palladium-gold catalysts on vinyl acetate support and preparation with them

摘要

A catalyst comprising from 0.1% by weight to 3% by weight of palladium, from 0.1% by weight to 3% by weight of gold, and a support comprising from 75% by weight at 99% by weight of titanium dioxide and from 1% by weight to 25% by weight of tungsten trioxide, in which the weight ratio of palladium to gold is 5: 1 to 1: 3.
