Production and Characterization of Isopropyl Laurate Using Immobilized Lipase
Immobilized Candida antarctica lipase (Novozym 435) was used for the synthesis of isopropyl laurate from isopropyl alcohol and lauric acid. A molecular sieve was used to shift the reaction towards the synthesis. The maximum enzyme activity was obtained at 60 °C. The amount of product seemed to be li...
