以固定化脂肪酶Lipozyme RM IM为催化剂，利用大豆油制备生物柴油。采用分析游离甘油的方法测定酯转化率，探讨了酯交换反应中水的含量、醇油比、反应时间、反应温度和底物加入方式为条件变量时对生物柴油制备的影响。研究结果表明：最适反应条件为水含量6％，醇油摩尔比4：1，反应时间12h，温度45℃，甲醇分三次加入，在此条件下该固定化脂肪酶催化大豆油的酯转化率可以达到45．2％。

Transesterification of soybean oil catalyzed by Novozym RM IM for biodiesel produc- tion was studied in this paper. The production rate of transesterification was also studies by ana- lyzing free glycerol. The optimal conditions were obtained for the trarisesterification on the basis of total glycerin content change before and after reaction： 6% water content, molar ratio of methanol to oil 4 ： 1, reaction time 12 hours, reaction temperature 45 ℃, and the way of adding methanol to add three times in the reaction system, which could receive greatest yield at 45.2%.
