Title: Lactic acid extraction with trioctyl amine

Abstract: Lactic acid extraction was carried out with trioctyl amine (TOA) in three diluents. The effect of initial lactic acid concentrations on the extraction efficiency was investigated. It was observed that although the percentage extraction remained constant or decreased but the loading ratio was increased in all the cases. The overloading was observed in the case of TOA in methyl isobutyl ketone (MIBK). The extraction of lactic acid was favored at a lower aqueous pH in all the diluents. The improvement of the extraction efficiency at a higher aqueous pH (= 6) was achieved by using the modified TOA (treated with HCl) in MIBK. However, the recovery of lactic was very poor in the case of modified TOA in MIBK, although the complete recovery was obtained for untreated TOA.
