| 摘 要： | 以5-甲基-2-巯基-1,3,4-噻二唑（MMTD）和水杨酸为主要原料，合成了一种新的噻二唑衍生物--水杨酸硫代-（5-甲基-1,3,4-噻二唑）酯（TM）。利用红外光谱、元素分析、液相色谱、质谱等分析手段对产物进行结构表征，采用热重分析评价产物的热稳定性，利用四球摩擦磨损试验机考察TM在菜籽油中的抗磨减摩性能。结果表明，合成产品TM的热分解温度为225.6 ℃，具有较好的热稳定性；合成产品TM具有良好的抗磨减摩性能，可作为油品的抗磨减摩添加剂，当添加量为0.6%时，其抗磨减摩效果最佳。

| Abstract: | A novel thiadiazole derivative(TM) was synthesized using 5-methyl-2-mecapto-1,3,4-thiadiazole and salicylic acid as main raw materials,and it was characterized by FT-IR,elementary analysis,LC and MS.The thermal stability of TM was evaluated by TGA,and its wear and friction behavior was investigated by a four-ball testing machine using rapeseed oil as base oil.Results show that the synthesized TM possesses good thermal stability with a thermal decomposition temperature of 225.6 ℃.Due to its good anti-wear and friction reducing properties,the obtained TM could be used as lube additive,it exhibits an optimum anti-wear and friction reducing performance at an amount of 0.6%. |
