Abstract
The present invention relates to a process for the preparation of dicarboxylic acids, specifically by the reaction of non-vicinal glycols; halogen containing derivatives in which the OH radical of the glycol is substituted by Cl, Br, or I; ester derivatives of glycols; and cyclic ether derivatives of glycols; with carbon monoxide in the presence of catalyst compositions essentially comprising rhodium or iridium compounds and complexes, together with a halide promoter.
