摘要/Abstract

摘要： 对C5 石油树脂进行马来酸酐接枝改性,用高碳醇进行酯化,研制柴油降凝剂。考察了马来酸酐质量
分数、引发剂(过氧化苯甲酰)质量分数、反应温度以及反应时间等因素对柴油冷凝点和冷滤点的影响。结果表明,
当马来酸酐质量分数为15%,引发剂质量分数为1.0%,反应温度为180℃,反应时间为3.0h时,得到的柴油降凝剂
具有较好的降凝降滤效果。

Abstract: The pour point depressant for diesel was prepared by firstly making modifacation of C5 petroleum resin with maleic anhydride, and then modified with octadecanol. Four factors were studied on the influence of freezing point and cold filter plugging point, which are, respectively, the amount of maleic anhydride and initiator, the time of reaction, the temperature of reaction. The result shows that, the best depression capacity of pour point depressant for diesel is acquired with the amount of maleic anhydride is 15%，and the amount of the initiator is 1.0%, and the temperature is 180 ℃ and the time is 3.0 h.
