| 摘 要： | 以栀子油为原料,采用碱催化法进行乙酯化反应,采用单因素试验考察醇油摩尔比、催化剂用量、反应温度、反应时间对乙酯化反应产物羟基值的影响,并进一步设计响应面试验优化反应条件.结果表明,栀子油乙酯化的最佳工艺条件为醇油摩尔比6.7∶1,催化剂用量为栀子油质量的1.65％,反应温度75℃,反应时间2.5 h,在此工艺条件下乙酯化反应产物的羟基值为146.62 mg(KOH)/g.

| Abstract: | Using gardenia oil as raw material,fatty acid ethyl ester was prepared by NaOH catalyzed transesterification.The effects of molar ratio of alcohol to oil,catalyst dosage,reaction temperature,reaction time on the ethyl esterification were evaluated through single factor tests,based on which response surface method was adopted to optimize the preparation conditions.The results showed that the optimum conditions for the esterification process were as follows,molar ratio of alcohol to oil,6.7∶1;catalyst dosage,1.65% of the mass of gardenia oil;reaction temperature,75 ℃;reaction time,2.5 h.Under the optimal conditions,the hydroxyl value of the product was 146.62 mg(KOH)/g. |
