摘　　要：以酸作为催化剂对地沟油与甲醇、乙醇酯化反应进行正交实验,实验中酸催化地沟油最佳反应条件,对于甲醇:温度为70℃,油醇摩尔比为1:40,催化剂浓度为7%,反应时间为6h,级差顺序依次是:油醇摩尔比、反应时间、催化剂浓度、温度;对于乙醇:温度为80℃,油醇摩尔比为1:30,催化剂浓度为5%,反应时间为6h,级差顺序依次是:油醇摩尔比、温度、催化剂浓度、反应时间。Cross compounding test between waste oils and methanol or ethanol based on H2SO4 was done. The best condition of test is, for methanol： temperature： 70℃ ; the proportion of methanol and waste oils： 1：40, the dosage of catalyst： 7%, the time of reaction： 6h. Influence sequence to outcome of factors is： the proportion of methanol and waste oils 〉the dosage of catalyst 〉the time of reaction 〉 temperature. For ethanol： temperature 80℃, the proportion of ethanol and waste oils 1：30, the dosage of catalyst 5 %, the time of reaction 6 h. influence to outcome of factors is： the proportion of ethanol and waste oils 〉 temperature 〉 the dosage of catalyst 〉 the time of reaction.
