| Abstract：Two environmentally friendly ashless and non-phosphorus S-（1H-benzimidazol-2-yl）methyl O-alkyl carbonodithioate derivatives were synthesized. Their structures were characterized by 1H NMR，13C NMR，IR，UV-vis，MS and EA. Their thermal stabilities as well as compatibilities with several kinds of organic solvents were inspected by TGA and oil solubility test. The tribological behaviors of these two benzimidazol derivatives in liquid paraffin were investigated by the four-ball tester. The results indicate that the prepared compounds can efficiently improve the load-carrying capacity. |
