摘　　要：以棉籽油与甲醇为原料,在催化剂(NaOH)的作用下,通过甲醇酯交换反应制备生物柴油。采用单因素和正交试验,考察醇油比、催化剂用量、反应温度、反应时间对生物柴油收率的影响。确定最佳反应条件为醇油比6:1,催化剂用量1.1%,反应温度55℃,反应时间55min。在此条件下,产率不低于95.89%。In this experiment,the biodieselwas prepared with cotton oiland methanolas raw materials by transesterification reaction,catalyzed by sodium hydroxide.By the single factor experiment and orthogonal test,factors influencing the yield of biodiesel were investigated,such as alcohol-oil ratio,catalyst amount,reaction temperature and reaction time.Suitable reaction conditions were obtained：molar ratio of methanol to oil was 6：1,amount of catalyst was 1.1%,reaction temperature was 55 ℃,and reaction time was 55 min.The yield could reach no less than 95.89%underthis condition.
