| 摘 要： | 探讨脂肪酸在超临界甲醇中酯化反应的规律及最佳条件。以橡胶籽油脂肪酸为原料，在间歇式高温高压反应釜中通过酯化反应制备生物柴油，分别考察了酯化反应条件如反应温度、反应时间、甲醇与脂肪酸的体积比对酯化率的影响。应用正交试验方法得出酯化反应的较适宜条件为：反应温度290℃，反应时间30min，甲醇与脂肪酸的体积比为4：1。在此反应条件下转化率可达99．2％。橡胶籽油生物柴油成分主要有亚油酸甲酯、油酸甲酯、亚麻酸甲酯，还有少量的硬脂酸甲酯、棕榈酸甲酯。 |

| Abstract: | Biodiesel was prepared by esterification of fatty acids of rubber seed oil in supereritical methanol without any catalyst in a high pressure and high temperature batch type reactor. The effects of reaction temperature, reaction time and the volume ratio of methanol to fatty acid on biodiesel yield were examined through experiments. The results show that the highest yield ofbiodiesel is 99.2% at 290 ℃ and 30 min reaction time with a ratio of methanol to fatty acid 4 ： 1 （ V ： F） by orthogonal experiments. The components ofbiodiesel from rubber seed oil are mainly methyl linoleate, methyl cis-9-octadecenoate and methyl linolenate with minor methyl octadecanoate and methyl hexadecanoate. |
