摘要： 采用脂环酸与1, 3 - 丙二醇为原料, 甲苯为带水剂, 合成了一种柴油抗磨剂。考察了酸醇物质的量比,反应温度及反应时间对酯化率的影响, 并利用红外光谱对产物结构进行表征。结果表明, 当脂环酸与醇的物质的量比为2. 1∶1、反应温度为1 5 0℃、反应时间1. 0 0h时, 酯化率可达到9 6. 1%, 红外光谱结果表明合成的产物是目标产物。合成产物具有较高的运动黏度和较低的凝点, 添加质量分数为2 0 0μ g / g的合成产物到加氢柴油中, 可有效改善其抗磨性, 同时降低柴油的凝点。

Abstract: The low freezing point diesel antiwear agent was prepared by using naphthenic acid and 1,3 propanediol as raw materials, toluene as water carrying agent. The effects of molar ratio, reaction time and temperature on the esterification rate of the product have been studied. Moreover, the product was characterized by IR spectra. The result show that the esterification rate could reach as high as 96.1% uner the condition of the mole radio of acid and glycol was 2.1∶1 at 150 ℃ for 1 h. IR spectra confirmed the formation of target product. The prepared product showed quite high kinematic viscosity and particularly low freezing point. When 200 μg/g of the antiwear agent was added to the diesel, the antiwear property could be enhanced and the freezing point of diesel was lowered down efficiently.
