    摘要: The present invention provides a method for purifying and recovering propionic acid from an aqueous mixture containing a fermentation product obtained from a fermentation process using glycerol as substrate, the method comprising optionally acidifying the aqueous mixture to a pH below 4.5, subjecting the aqueous mixture to an extraction with extracting agent containing a heavy extractant and optionally a light extractant as a diluent to obtain an extract comprising the extracting agent and organic acids, and a raffinate comprising water and any unreacted glycerol, and subjecting the extract to vacuum evaporation to separate propionic acid-containing organic acids from the extractant.
