Abstract

The esterification reaction of previously obtained l,4-sorbitan with acrylic acid using Novozym 435 was carried out in t-butanol as solvent. Immobilized lipase Novozym 435 showed high enzymatic activity at $50^{\circ}C$ in t-butanol and optimum contents of Novozym 435 added in the esterification reaction was 3%(w/v). The maximum conversion rate was 55.8% when initial concentration was 50g/L and conversion rate of this reaction was 63.5% when the molar ratio of l,4-sorbitan to acrylic acid was 1:3.
