摘　　要：以餐饮废油为原料,采用酯交换法合成生物柴油。通过单因素控制,优化反应条件,再进行正交实验,确定了较优的反应条件:反应温度45℃,反应时间6 h,催化剂用量约为餐饮废油重量的0.8%,n(餐饮废油):n(甲醇)为1:6。生物柴油通过减压蒸馏进行提纯,并测定目标化合物的十六烷值和黏度,经分析确定为目标化合物。生物柴油的产率为86.73%。Waste cooking oil as raw material, the method of transesterification could be used to the synthesis of biodiesel.Through single-factor control, the reaction conditions were optimized, then orthogonal experiment, determined the optimum reactionconditions as follows： reaction temperature of 45℃, reaction time 6h, the amount of catalyst is 0.8% of the ratio of about wastecooking oil, castor oil / methanol is 1：6. Biodiesel was purified by vacuum distillation to determine target compounds sixteen cetanenumber and viscosity, which could be identified as the target compounds. Biodiesel production yield was 86.73%.
