Three new oil‐soluble alkylthiomethylbenzotriazoles were synthesised with the reaction of 1‐chloromethylbenzotriazole and sodium alkyl mercaptan in iso‐propanol at room temperature for 12 h. Their load‐carrying capacity and friction and wear properties when added to liquid paraffin were then evaluated using a Seta‐shell four‐ball machine. Their thermal stability in static air was examined by DSC analysis, and their friction reduction and antiwear mechanisms were investigated using XPS and AES analysis.
