Abstract

In this study, tetradecyl methacrylate-maleic anhydride-benzylidene acetone (C₁₄MC-MA-MCA) terpolymers were synthesized via free radical polymerization and evaluated as pour point depressants (PPDs) for coal-based diesel. The findings indicate that the C₁₄MC-MA-MCA (3:1:1) terpolymer exhibited the most effective inhibition of the solid point (SP) at 1500 ppm concentration. Specifically, it reduced the SP of coal-based diesel from − 4 to − 42 °C, marking a significant decrease of 38 °C. Furthermore, the crystallization behavior and SP reduction mechanism of C₁₄MC-MA-MCA in coal-based diesel were investigated using viscosity analysis and polarized optical microscopy (POM).

甲基丙烯酸酯三元聚合物对煤基柴油低温流动性的影响

本研究通过自由基聚合法合成了甲基丙烯酸十四酯-马来酸酐-苯亚甲基丙酮（C14MC-MA-MCA）三元共聚物，并将其作为煤基柴油的降凝剂（PPD）进行了评估。研究结果表明，C14MC-MA-MCA（3:1:1）三元共聚物在浓度为 1500 ppm 时对凝固点（SP）的抑制效果最佳。具体而言，它将煤基柴油的固点温度从 - 4 ℃ 降至 - 42 ℃，显著降低了 38 ℃。此外，还利用粘度分析和偏振光学显微镜（POM）研究了 C14MC-MA-MCA 在煤基柴油中的结晶行为和降低固点的机理。
