RECOVERY OF CARBOXYLIC ACID FROM ORGANIC SOLUTION THAT CONTAINS AN AMINE AND AN EXTRACTION ENHANCER |
摘要 |
Recovery of carboxylic acid from an amine-based, water-immiscible organic extractant solution thereof that contains an extraction enhancer, by extraction of acid into an aqueous phase. In a preliminary step the enhancer is removed from the extractant solution by extraction with an aqueous solution containing at least 50 % by weight of a salt of the carboxylic acid present in the extractrant. The process is applicable to the recovery of carboxylic acid from a fermentation broth.
