Beschreibung
Zusammenfassung:	Supported catalyst useful in the preparation of carboxylic acid salts, said catalyst comprising; an alkali resistant support, a plurality of metal particles selected from the group consisting of osmium, iridium and rhodium and a coating of a catalytically active metal selected from the group of copper, cobalt, nickel, cadmium or mixtures thereof. Cette invention se rapporte à un catalyseur sur support servant à la préparation de sels d'acide carboxylique, ce catalyseur comprenant: un support résistant aux alcalis, plusieurs particules métalliques choisies dans le groupe de l'osmium, de l'iridium et du rhodium et un revêtement fait d'un métal à action catalytique choisi dans le groupe du cuivre, du cobalt, du nickel, du cadmium ou de mélanges de ceux-ci.
