摘　　要：研究了固体碱CaO催化橡胶籽油与甲醇进行酯交换反应制备生物柴油的工艺条件。结果表明,焙烧温度为800℃,焙烧时间为2 h时,由CaCO3分解制得的CaO具有最高的反应活性。以此CaO为催化剂制备橡胶籽油生物柴油的最佳工艺条件为:催化剂CaO用量为油质量的1.5%,反应温度65℃,醇油摩尔比为15∶1,反应时间6 h。在此反应条件下,橡胶籽油生物柴油转化率为90.70%。The preparation technique of biodiesel from rubber seed oil catalyzed by solid base of calcium oxide was studied. The result indicated that the optimal conditions for catalyst preparation of calcium oxide and transesterfication of rubber seed oil were as follows：calcination temperature 800℃, calcination time 2 h, catalyst dosage 1.5 % （ based on the mass of oil）, the molar rate of methanol to oil 15： 1, reaction temperature 65℃ , reaction time 6 h. Under the optimal conditions, the transesterification rate of biodiesel from rubber seed oil was 90.70%.
