The lipase-catalyzed transesterification of butyl alcohol and vinyl laurate in [Omim][TfO] was investigated as a model reaction for the continuous production and separation system in ionic liquids. Since the ester product is insoluble in ionic liquids, the product could be easily separated from reaction mixture. The optimum substrate molar ratio of butyl alcohol to vinyl laurate was 1.2:1. The hightest productivity, 523.5g/g lipase/hr was obtained with 10mg Novozym 435 at 50°C. A double-layer type stirred tank reactor was developed for the continuous production of butyl laurate. The results showed that our developed system could be successfully operated for at least 60 hours with the optimum flow rate of 0.375 mL/h for this system.
