Abstract

Production of ethyl lactate in esterification reaction by candida antarctica lipase enzyme was studied The optimal conditions of the synthesis of ethyl lactate was obtained to be: 20 μl/ml lactic acid, 160 μl/ml ethanol, 15 mg/ml Novozym 435 lipase enzyme. The yield obtained is over 90% and the enantiomeric exess is about 20% at temperature of 40 °C in case of 24 hours reaction time under 150 rpm revolution rate . In the present study, the enantioselective transport of the (L)-enantiomer from racemic lactic-acid has been presented through a lipase-facilitated supported liquid membrane (SLM) containing ionic liquids.
