Process for the manufacture of carboxylic acids

Abstract From the Canadian patent

A process for manufacture of branched carboxylic acids from branched olefins by means of reaction with carbon monoxide and a solid acid catalyst characterized in that a branched olefin or a precursor thereof, is reacted in continuously backmixed reactor, with continuously supplied carbon monoxide and water, while continusously an effluent is withdrawn comprising branched carboxylic acid, non-converted olefin, carbon monoxide and water in the , presence of an acidic ion exchanger having sufficient acid groups to provide requisite protons for conversion of said olefin or a precursor of it and , carbon monoxide into branched carboxylic acids.
