ABSTRACT:
A process for the production of a carboxylic acid by the reaction of a liquid lower alkanol with carbon monoxide at a temperature of from about 150.degree. C. to about 250.degree. C. and a carbon monoxide pressure of from about 2,000 psig to about 10,000 psig in the presence of a soluble liquid phase catalyst prepared from the following ingredients: (1) MX.sub.n wherein M is selected from the group consisting of Co and Ni, X is selected from the group consisting of carboxylate anions of from 2 to 10 carbon atoms, halides, oxides, acetyl acetonate, carbon monoxide, and hydrogen; and n is from 1 to 5; (2) R.sub.3 P wherein R is alkyl, aryl, or alkylaryl of from 4 to 10 carbon atoms; and (3) hydrogen iodide or an iodide source such as iodine, alkyl iodides and alkali metal or alkaline earth iodides.
