Abstract: A new diesel pour point depressant (PPD) was synthesized using αmethacrylic acid ester, maleic anhydride, and styrene as raw materials.The results showed that the optimum reaction conditions were as follows: the mass fraction of azodiisobutyronitrile (AIBN) was 0.8%, the mole ratio of αmethacrylic acid ester, maleic anhydride and styrene was 6∶1∶1, the reaction temperature was 80 ℃, and the reaction time was 8 h. Meanwhile, the effect of depressants was best when its mass fraction was 0.1%. At the same time, A, B, and C surface active agent were added into PPD according to the different proportion, respectively. It was found diesel pour point was decreased by 17 ℃ when PPD and B surfactant was compounded with mass ratio of 4∶1.

摘要: 采用α - 甲基丙烯酸混合酯、 马来酸酐和苯乙烯共聚, 制备新型柴油降凝剂( P P D) 。实验结果表明, 此 P P D最佳的合成条件是: 引发剂质量分数为0. 8%, α - 甲基丙烯酸混合酯、 苯乙烯、 马来酸酐的物质的量比为6∶1∶ 1, 聚合温度为8 0℃, 聚合时间8h。当降凝剂添加质量分数为0. 1%时, 降凝效果达到最优。同时将此P P D分别与 A、 B、 C表面活性剂等按不同比例复配, 结果发现与B表面活性剂按质量比4∶1复配后柴油的凝点降低了1 7℃, 降 凝效果最好。
