Lactic acid production, separation and/or recovery process |
摘要 |
A process for the production of lactic acid and for the separation and/or recovery of lactic acid from a lactate feed solution. A lactate feed solution preferably obtained from a fermentation broth is combined with and extracted by a water immiscible trialkyl amine in the presence of carbon dioxide. Lactic acid is recovered from the resulting organic phase. Recovered carbonate or bicarbonate from the aqueous phase is preferably recycled to the fermentor and regenerated extractant is preferably recycled for use in the extraction.
