Abstract: A heterocyclic derivative of (2-sulphuronebenzothiazole)-3-methyl dodecanoate was synthesized. Its tribological performance when added to liquid paraffin was evaluated on a four-ball tester and a ring-on-block machine. Results indicate that compared with the base oil the wear resistance and load-carrying capacities of the oil with novel additive are improved, and the friction coefficient is decreased. There is an optimal content of the novel compound, at which the corresponding oil gives the highest maximum non-seizure load. Above the content,the load carrying capacity of the oil is not increased but decreased. The nature of the film formed on the rubbed surface was investigated by X-ray photoelectron spectroscopy (XPS) analysis, and the action mechanism of the novel compound was discussed.
