2-Ethylhexyl palmitate has been prepared in organic solvents catalyzed by an immobilized lipase QLM. Microwave irradiation was used to improve the enzyme activity and shorten the reaction time. The reaction conditions under microwave have been optimized. Compared with that of the free QLM under classical heating, the immobilized QLM under microwave exhibited higher enzyme activity and the conversion could achieve 99% in about 3.0 h. Furthermore, the immobilized QLM displayed excellent reusability under microwave irradiation.
