Date Nov. 30, 1995Recovery of carboxylic acid from an amine-based, water-immiscible organic extractant solution thereof that contains an enhancer, by extraction of the acid into an aqueous phase. A low molecular, at least partly water-miscible organic compound being a C2-C5 alkanol, an acetate of a C1-C3 alkanol and acetone is used as enhancer. In operation, the enhancer is recovered and recycled. The process is applicable, among others, to the recovery of carboxylic acid from a fermentation broth.
