摘要:
A process for extracting a hydroxy-functional carboxylic acid from a fermentation broth comprising: (a) treating a fermentation broth comprising an ammonium salt of a hydroxy-functional carboxylic acid with an organic extraction solvent, in the the organic extraction solvent is selected from the group consisting of an organic amine having a boiling point higher than 100 ° C, when measured at a pressure of 101 kPa (1 atmosphere) that is immiscible in water and an organic extraction solvent having a boiling point of at least 175C, when measured at a pressure of 101 kPa (1 atmosphere) to form a mixture; and (b) heating said mixture to dissociate said ammonium salt and form a reaction product comprising said carboxylic acid and said organic extraction solvent.
