Abstract
The DL-lactic acid resolution was studied in a laboratory scale tangen tial flow ''membrane'' module equipped with a flat sheet zeolite disc. Chiral selector N-3,5-dinitrobenzoyl-L-alanine was adsorbed on the ze olite disc. The D/L lactic acid enantioratio was determined by a Merck -Hitachi HPLC equipment in the aqueous source phase and receiver phosp hate buffer as well.
