中文摘要:
      以鸦胆子油为原料，无水乙醇为反应物与溶剂，对鸦胆子油的乙酯化工艺进行研究。通过单因素实验与正交实验，确定鸦胆子油乙酯化反应的最优条件为：选择甲醇钠为催化剂，催化剂用量0.6%（以鸦胆子油质量计），醇油摩尔比6∶?1，反应温度75?℃，反应时间2 h。在最优工艺条件下，鸦胆子油脂肪酸乙酯得率为92.38%。
英文摘要:
      With Brucea javanica oil as raw material, anhydrous ethanol as reactant and solvent, the ethyl esterification of Brucea javanica oil was studied. The optimal conditions of the ethyl esterification of Brucea javanica oil were obtained by single factor experiment and orthogonal experiment as follows: with sodium methoxide as catalyst, catalyst dosage 0.6% (based on the mass of Brucea javanica oil), molar ratio of anhydrous ethanol to Brucea javanica oil 6∶?1, reaction temperature 75?℃ and reaction time 2 h. Under these conditions, the yield of fatty acid ethyl ester of Brucea javanica oil was 92.38%.
