| 用甲苯作携水剂，亚油酸和1，3-丙二醇在氨基磺酸催化下反应合成单亚油酸丙二醇酯，采用红外光谱对其进行结构分析,通过高频往复摩擦试验机评价其抗磨效果并研究了其对加氢裂化柴油理化性质的影响。结果表明，目标产物的最佳合成工艺条件为：反应物料酸醇物质的量比1∶?1.1，反应时间9 h，反应温度145?℃，催化剂用量为酸醇总质量的0.8%。在最佳合成工艺条件下，酯化率达到95.9%。合成产物具有较好的抗磨性能，其磨斑直径（WS1.4）为388 μm（添加量200 μg/g）。得到的酯型产物单亚油酸丙二醇酯具有较低酸值（KOH），为0.80 mg/g，其作为柴油抗磨剂使用时，主要性能指标均符合抗磨剂相关标准要求，将其加入到柴油中，柴油的各项理化性能亦不受影响。 |
| 英文摘要: |
| With toluene as water carrying agent, propanediol mono linoleate was synthesized from the esterification of linoleic acid and 1, 3-propanediol catalyzed by amino sulfonic acid. The structure of the product was analyzed by infrared spectroscopy, its antiwear effect was evaluated by high frequency reciprocating friction test machine, and its effects on physicochemical properties of hydrogen cracking diesel oil were studied. The results showed that the optimal synthesis conditions of the target product were determined as follows: molar ratio of linoleic acid to 1,3-propanediol 1∶?1.1, reaction time 9 h, reaction temperature 145?℃, dosage of catalyst 0.8%. Under these conditions, the esterification rate reached 959%. The synthetic products had good antiwear property, and its WS1.4 achieved 388 μm (addition amount 200 μg/g). Meanwhile, this ester product had lower acid value, which was 0.80 mgKOH/g. As diesel antiwear agent, its main performance indexes could meet the standard requirements of antiwear agents, and the physicochemical properties of diesel oil were not affected when the ester product was added to the diesel oil. |
