Abstract
The disclosure relates to methods for electrochemical reductive carboxylation of an unsaturated organic substrate to form a dicarboxylic organic product. The unsaturated organic substrate is electrochemically reduced with a carbon dioxide reactant in an ionically conductive, water-immiscible reactant medium to form the dicarboxylic organic product. The dicarboxylic organic product is recovered in an aqueous product medium. Example dicarboxylic organic products include phthalic acid, naphthalenedicarboxylic acid, furan-2,5-dicarboxylic acid, thiophene-2,5-dicarboxylic acid, pyrrole-2,5-dicarboxylic acid, adipic acid, suberic acid, sebacic acid, and 1,12-dodecanedioic acid.
