The stability of the esterification reaction. The reaction system comprised 2.82 g of fatty acid, 580 μl of ethanol added in a three-step manner, 9% (wt/vol) molecular sieves added 1 hour after the start of the reaction and 0.33 g of immobilized lipase at 30°C for 5 hours and spun at 190 rpm. After each batch, immobilized lipase membrane was taken out, dried and reused in a fresh reaction.
