摘要：

D,L-lactic acid and D,L-alanine solutes resolution was studied in supported liquid membrane using a polypropylene hollow-fiber module. The enantioselective transport of solutes was facilitated by N-3,5-dinitrobenzoyl-L-alanine-octylester chiral selector, which was dissolved in toluene organic solvent. The maximum D,L-lactic acid separation factor achieved was 2 and that for the D,L-alanine was 1.75, in both cases the D-enantiomer flux was preferred.
