A process to manufacture a carboxylic acid salt is disclosed wherein an aqueous solution of a primary alcohol is contacted with a base hydroxide in the presence of an effective amount of a catalyst consisting essentially of an alkali resistant support, from about 0.05 wt.% to about 10 wt.%, based on the total weight of the catalyst of an anchor metal selected from the group consisting of platinum, palladium, ruthenium, and gold, and between about 1 wt.% and about 50 wt.%, based on the total weight of the catalyst, of an element selected from the group consisting of copper, cobalt, nickel, and cadmium combined with the anchor metal.
La présente invention concerne un procédé d'élaboration d'un sel d'acide carboxylique consistant à mettre en contact une solution aqueuse d'un alcool primaire avec un hydroxyde de base en présence d'une quantité suffisante d'un catalyseur. Ce catalyseur est composé essentiellement: pour environ 0,05 % à environ 10 % du poids total du catalyseur d'un support résistant aux alcalis; d'un métal de fixation appartenant au groupe constitué du platine, du palladium, du ruthénium et de l'or; et, pour environ 1 % à environ 50 % du poids total du catalyseur, d'un élément appartenant au groupe constitué du cuivre, du cobalt, du nickel et du cadmium, combiné au métal de fixation.
