| 中文摘要: |
| 以石榴籽油为原料、无水乙醇为反应物，在碱性催化剂氢氧化钠的作用下，对石榴籽油进行脂肪酸乙酯化工艺研究。在单因素实验的基础上，利用正交实验优化乙酯化工艺条件。结果表明：最优乙酯化工艺条件为反应温度75℃、反应时间2 h、醇油摩尔比8∶1、催化剂用量0.5%（以石榴籽油质量计），在该条件下乙酯含量可达95.88％。 |
| 英文摘要: |
| With pomegranate seed oil as raw material, anhydrous ethanol as reactant, and sodium hydroxide as catalyst, ethyl esterification of fatty acids of pomegranate seed oil was studied．Based on single factor experiment, the process conditions of ethyl esterification were optimized by orthogonal experiment. The results showed that the optimal process conditions of ethyl esterification were obtained as follows：reaction temperature 75℃，reaction time 2 h，molar ratio of anhydrous ethanol to pomegranate seed oil 8∶1， catalyst dosage 0.5%(based on the mass of pomegranate seed oil).Under these conditions,the ethyl ester content was 95.88%. |
