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) coated with copper. The support comprises at least about 10% (by weight) non-copper metal, and the copper-containing coating comprises from about 0.005 to about 0.5 grams of copper (per gram of said metal support).In another embodiment, the catalyst comprises a metal support (preferably a metal sponge support) coated with silver. The support comprises at least about 10% (by weight) non-silver metal, and the silver-containing coating comprises from about 0.005 to about 0.5 grams of copper (per gram of said metal support).In another embodiment, the catalyst comprises at least about 15% (by weight) non-copper metal, and at least about 10% (by weight) copper. In yet another embodiment, the catalyst comprises at least about 15% (by weight) non-silver metal, and at least about 10% (by weight) silver. In both these embodiments, it is particularly preferable for the catalyst to be in the form of a metal sponge.This invention is also directed to copper-containing and silver-containing catalysts which may, for example, be used in the above process. This invention is further directed to processes for making such catalysts.
