Abstract

In this study, the lauroyl sucrose ester was synthesized by microwave-assisted lipase-catalyzed reaction under non-aqueous system. The influence of the microwave power, the amount of molecular sieve added and the reaction time on the conversion of sugar esters were explored. The results showed that compared with conventional heating, microwave-assisted lipase-catalyzed method was short time and can reduce energy consumption. And the thin layer chromatography showed that the lauroyl sucrose ester synthesized by microwave-assisted lipase-catalyzed reaction containing only a single product spot. The optimal conditions was built when the reaction was carried out under 200W of the microwave reaction power and 15 g/L of molecular sieve for 25 min. The maximum conversion of lauroyl sucrose ester was 63.8% under the optimal condition.After three times batch reaction, the residual activity of lipase was 52.4%.
