| Abstract: | The synthesis of a new type of oil additive, 4,5-di(cetyl thio)-1,3-dithiole-2-thione, is described. The thermal stability of the compound was investigated by thermal gravity analysis (TGA). The tribological properties of the compound as additive in liquid paraffin were also evaluated using a four ball tester. The results show that the novel compound has good tribological properties in liquid paraffin. The lubricating mechanism was studied by electron probe microanalysis (EPMA) and X-ray photoelectron spectroscopy (XPS). |
