中文摘要：

以地沟油为原料,采用离子交换树脂Amberlite IR-120催化地沟油环氧化合成绿色增塑剂。在对地沟油进行脱水除杂、碱炼脱酸预处理,分析理化性质和脂肪酸组成的基础上,探讨了催化剂用量、30%H2O2用量、冰乙酸用量、反应温度及反应时间对环氧化反应的影响。结果表明：地沟油主要由棕榈酸（19.86%）、油酸（34.98%）和亚油酸（33.31%）组成,具有较高的不饱和度,理论环氧值为5.3 mol/100 g。最佳环氧化工艺条件为：地沟油与30%H2O2质量比1∶2.5,地沟油与冰乙酸质量比1∶0.9,催化剂用量3%,反应温度65℃,反应时间3 h。在最佳条件下,制备得到的环氧地沟油增塑剂的环氧值为4.61 mol/100 g,相对环氧转化率可达87%。

英文摘要：

Green plasticizers were synthesized by epoxidation of swill-cooked dirty oil using the ion exchange resin Amberlite IR-120 as catalyst.On the basis of dehydration,purification,alkali refining,physicochemical property and fatty acid composition analysis of swill-cooked dirty oil,the influences of the dosages of catalyst,30% H2 O2and acetic acid,reaction temperature and reaction time on the epoxidation reaction of swill-cooked dirty oil were discussed.The results demonstrated that the swill-cooked dirty oil had high degree of unsaturation,composed of palmitic acid （19.86%）,oleic acid （34.98%） and linoleic acid（33.31%）,and the theoretical epoxy value was 5.3 mol/100 g.In addition,the optimal conditions of epoxidation reaction were obtained as follows：mass ratio of swill-cooked dirty oil to 30% H2O2 1∶2.5,mass ratio of swill-cooked dirty oil to acetic acid 1∶0.9,dosage of catalyst 3%,reaction temperature 65 ℃ and reaction time 3 h.Under the optimal conditions,the epoxy value of epoxidized swill-cooked dirty oil plasticizer was 4.61 mol/100 g and the relative epoxy conversion rate was up to 87%.
