Abstract
A process for manufacture of α,α-branched carboxylic acids from linear olefins by means of reaction with carbon monoxide and an acid catalyst, characterized in that a linear olefin containing from 2 to 5 carbon atoms, or a precursor thereof, is reacted in a batch reactor or a continuous reactor, with carbon monoxide and water, in the presence of a catalyst having sufficient acid groups to provide requisite protons for the formation of Koch acid, and in the presence of a polar non-coordinating organic solvent.
Claims10
A process for manufacture of α,α-branched carboxylic acids from linear olefins comprising reacting the linear olefins with carbon monoxide in the presence of an acid catalyst, wherein the linear olefin, containing from 2 to 5 carbon atoms, or a precursor thereof, is dimerized and reacted in a batch reactor or continuous reactor with carbon monoxide and water, in the presence of a catalyst, having sufficient acid groups to provide requisite protons for the formation of Koch acid, and carbon monoxide into quaternary carboxylic acids, and in the presence of a polar non-coordinating organic solvent.
