摘　　要：以餐饮废油为原料,采用超声辅助碱催化法制备生物柴油,通过响应面试验探讨了温度、催化剂用量、醇油比对生物柴油转化率的影响,得到最佳制备工艺条件为:在超声功率50 W、频率28 Hz的条件下,温度62.47℃,催化剂用量0.98%,反应时间30 min,醇油比7∶1(质量比)。在此条件下,生物柴油转化率为90.26%。Ultrasonic - assisted alkali - catalyzed preparation of biodiesel from swill - cooked dirty oil was studied. The influences of temperature, catalyst dosage, mass ratio of methanol to oil on biodiesel conver- sion rate were studied by response surface methodology（RSM）. The optimal preparation conditions were as follows ： ultrasonic power 50 W, ultrasonic frequency 28 Hz, temperature 62.47℃, catalyst dosage 0.98%, reaction time 30 min, mass ratio of methanol to conversion rate was 90.26%. oil 7： 1. Under the optimal conditions, biodiesel
