Abstract

This invention is directed to a process for making a salt of a carboxylic acid. The process comprises contacting a catalyst with an alkaline mixture comprising a primary alcohol.In one embodiment, for example, the catalyst comprises a metal support (preferably a metal sponge support) having a copper-containing active phase at the surface thereof. The support is resistant to deformation under the conditions of the dehydrogenation reaction.In another embodiment, the catalyst comprises a metal sponge having a copper-containing active phase at the surface thereof and a supporting structure containing at least 10% non-copper metal.This invention is also directed to copper-containing catalysts which may, for example, be used in the above process. This invention is further directed to processes for making such catalysts.
