More Information
Summary:A microspheroidal support for the manufacture of a vinyl acetate catalyst which support comprises substantially inert microspheroidal particles of a mixture of silica and 0.5 to 5 wt% (based on the total weight of the support) of aluminium oxide. A vinyl acetate catalyst comprising the microspheroidal support, palladium, at least one metal, M, selected from the group consisting of gold, cerium, copper and mixtures thereof and at least one metal. A, selected from the group consisting of Group I, Group II, lanthanide and transition metal promoters. Ce support microsphérique est destiné à fabriquer un catalyseur d'acétate vinyle et comprend des particules microsphériques sensiblement inertes d'un mélange de silicium et d'oxyde d'aluminium selon un pour-cent en poids compris entre 0,5 et 5 (d'après le poids total du support).
