摘要：

Lipase-catalyzed transesterification (alcoholysis) of low-erucic acid rapeseed oil and 2-ethyl-1-hexanol without an additional organic solvent was studied in stirred batch reactors. Of a number of commercially available enzymes investigated, the best results were obtained with a Candida rugosa lipase. The optimal transesterification conditions were an oil/alcohol molar ratio of 1:2.8, a minimum of 1.0% (w/w) added water, and with a temperature of 37-55 degrees C. Under the optimal conditions, a nearly complete conversion was obtained in one hour with 14.6% (w/w) lipase, whereas 0.3% (w/w) lipase required 10 h for similar results. The enzyme was inactivated at 60 degrees C.
