Patent

CA 2081942

This invention provides a process for producing improved catalysts for the production of alkenyl alkanoates by the reaction of an alkene, an alkanoic acid and an oxygen-containing gas. The catalysts contain palladium, gold and a potassium promoter and are characterized by a reduced sodium content which results in increased catalyst activity. The reduced sodium content is obtained by using essentially sodium-free starting materials in the process for producing the catalysts.

Méthode de préparation de catalyseurs améliorés pour la production d'alcanoates d'alcényle par la réaction d'un alcène, d'un acide alcanoïque et d'un gaz renfermant de l'oxygène. Les catalyseurs renferment du palladium, de l'or et un promoteur à base de potassium; ils ont une teneur réduite en sodium, ce qui augmente leur efficacité. La teneur réduite en sodium est obtenue en utilisant des matières de départ pratiquement exemptes de sodium dans la préparation des catalyseurs.
