摘　　要：合成了一种新型S-N型1,3,4-噻二唑-2-硫酮衍生物(DTSO),用元素分析、红外光谱技术和核磁共振技术对其结构进行了表征;用热重分析仪考察了其热稳定性;在四球摩擦磨损试验机上评价了其作为菜籽油(RSO)添加剂的摩擦磨损性能;用扫描电子显微镜观察分析了钢球磨损表面形貌和元素化学形态。结果表明:所合成的化合物DTSO具有良好的热稳定性,能够有效提高菜籽油的抗磨减摩性能。A novel 1,3,4-thiadiazole-2-thione derivative DTSO was synthesized .The complex was confirmed by elemental analyses, IR and 1HNMR. The thermal properties of DTSO were investigated by thermogravimetric analyzer （TGA）; and the tribological properties of DTSO as additive in rapeseed oil were examined by using four-ball tester. Worn surface morphology was analyzed by means of scanning electron microscopy （SEM） .The result indicated that DTSO possessed good thermal stability and this novel compound as an additive in rapeseed oil was able to obviously decrease the wear rate and friction coefficient.
