Abstract
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 a batch reactor or a plug flow reactor with 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, and in the presence of a polar non-coordinating organic solvent.
