Abstract
A process for recovering carboxylic acids from an aqueous mixture such as a fermentation broth using a solvent containing at least one olefin without the need for first removing the spent microorganism cells is provided. A co-solvent which increases the partition coefficient of the solvent relative to the carboxylic acid may optionally be included. The resulting carboxylic acid is hydrogenated to produce a saturated carboxylic acid.
