ABSTRACT:
Organic acids contained in aqueous solution are separated and/or recovered by a process comprising adding an alcohol to the aqueous solution to esterify the acids present, while preferably simultaneously contacting the alcoholic mixture with a water-immiscible solvent and separating layers into an aqueous phase and an organic phase, whereby extraction with the water-immiscible solvent shifts the equilibrium toward the formation of more esters. The esters of the acids may than be recovered as by distillation.
