摘　　要： 合成了两个新型无灰六氢吡啶二硫代氨基甲酸苯胺羰甲基酯化合物;用核磁共振氢谱、核磁共振碳谱、红外光谱、紫外光谱、质谱和元素分析对其结构进行了表征;用四球摩擦机测试了其作为润滑油添加剂在液体石蜡中的极压性能;采用热重分析和油溶性实验考察了热稳定性及其在有机溶剂中的溶解性。结果表明,这两个新型化合物具有较好的承载能力和热稳定性。 Two novel ashless piperidine dithiocarbamate acetamidobenzene derivatives were synthesized and their chemical structures were characterized by 1H NMR,13C NMR,IR,UV-vis,MS and elemental analysis.Their extreme pressure（EP） behaviors as lubricant additives in liquid paraffin were evaluated using a four-ball tester.Their thermal stabilities and compatibilities with several kinds of organic solvents were inspected by TGA test and oil solubility test.The results indicate that the two novel compounds possess excellent load-carrying capacity and thermal stability.

关 键 词： 润滑油添加剂 表征 热稳定性 承载能力
