Abstract

L'invention concerne un catalyseur qui est utile, par exemple, pour la fabrication d'acétate de vinyle à partir d'acide acétique, d'éthylène et d'oxygène. Ce catalyseur contient les métaux palladium et or, et un métal choisi dans le groupe constitué par le zirconium et le rhénium, sur un support poreux. Le catalyseur est fabriqué en absorbant des sels hydrosolubles de ces métaux sur le support, en précipitant les métaux sous la forme de sels insolubles et en réduisant le sel en métal.
