摘要
研究了利用废豆油和甲醇作为原料,在催化剂甲醇钠的作用下通过酯交换反应,制备脂肪酸甲酯即生物柴油和丙三醇(甘油),根据正交实验结果,较佳的工艺条件为:摩尔比7∶1、反应温度60℃、反应时间90min、催化剂用量0.8%。在此工艺条件下,生物柴油的收率可达93.71%;精馏后的甘油纯度较高,达到97.5%以上。
The fatty acid methyl ester（biodiesel） and glycerod（glycerin） obtained by transesterification between waste bean oil and methanol under the action of NaOCH3.Through orthogonal analysis,the optimum conditions were obtained for the transesterification： molar ratio of methanol to oil 7∶1,reaction temperature 60℃,reaction time 90min,and the amount of NaOCH3 0.8%.The yield of the biodiesel can reached 93.71%.The glycerol purity after distillation can reach more than 97.5%.
