| 摘 要： | 以棕榈油和棉籽油为原料,利用甲醇钠的高活性催化合成脂肪酸甲酯(FAME),通过对FAME的2种合成方法——化学法和超声法,所得FAME的转化率,以及反应条件的比较,来研究更适合于工业化生产的合成方法。通过实验确定了化学法和超声法合成棕榈油和棉籽油脂肪酸甲酯的最佳工艺条件;并且要达到相同的FAME转化率时,采用超声法时对反应条件的要求比化学法的要求低,尤其是反应时间明显缩短,因此更适合在工业生产上应用。此外,采用二次酯化或者脱除甘油,所得到的FAME的转化率明显比一次酯化的转化率有所提高。

| Abstract: | Used palm oil and cottonseed oil as raw material,and utilized the high catalytic activity of methanol sodium to synthesize fatty acid methyl ester (FAME) . The two synthesize methods of FAME- chemical method and ultrasound method were studied,in order to find which is more suitable for industrial production through the comparison of the FAME conversion degree and conditions. Through the experiments and determine the optimum conditions of chemical and ultrasound method to synthesize the palm oil and cottonse... |
