Abstract

Lactic acid extraction and back-extraction were studied using trioctylamine as reactive agent. Different hollow fiber and capillary membrane containing contactors with areas between 0.005 and 1.4 m²as well as various temperatures flow rates and phase ratios of up to 1:40 solvent/feed (S/F) were tested. Despite starting with a low lactic acid concentration of only 0.8 % which allows for most lactic acid-producing bacteria to remain active an aqueous solution with a concentration of 5.8% can be obtained assuming phase ratios of S/F of 1:40 for the extraction and 4:1 for the back-extraction. The technique might be a promising pathway for an alternative downstream processing of lactic acid since it allows the continuous removal of lactic acid from a fermentation broth.
