摘　　要：介绍了以甲醇钠为催化剂,精制棕榈油与甲醇进行酯交换反应制备生物柴油的工艺过程。采用正交实验的方法研究得到酯交换反应的最佳工艺条件为:醇油摩尔比6:1,催化剂甲醇钠的质量分数为0.5%,反应温度60℃,反应时间60min,收率达到96%。该工艺设备简单,工艺成熟,适于中小规模生产。According to the orthogonal experiments, the optimal transesterification conditions for palm oil and methanol catalyzed by sodium methoxide to form biodiesel were investigated. The following suitable conditions for transesterification of the palm oil were obtained： molar ration of methanol to oil 6：1, reaction time 60min, reaction temperature 60℃ and amount of catalyst 0.6% of the oil weight. Its yield may reach 96%. The process is mature, and it costs little for equipment. It is suitable for medium-sized and small-scale production.
