1,3,4-噻二唑衍生物的合成及其抗腐减摩性能
Synthesis of 1,3,4-Thiadiazole Derivative and Its Anti-Corrosion and Friction-Reducing Performance
摘要
Abstract
A thiadiazole derivative named 2-benzylmercapto-5-methyl-l,3,4-thiadiazole (TM), a novel additive for conventional lubricating oil, was synthesized from 2-mercapto-5-methyl-l, 3,4-thiadiazole, and characterized by means of FTIR, elemental analysis, liquid chromatography and mass spectrometry. Thermal gravimetric analysis was carried out to evaluate its thermostability and the results showed that the thermal decomposition temperature of TM was at 232 t. Anti-corrosion and friction-reducing performances of TM in based stock were investigated by means of copper strip corrosion and four ball tester test. The results indicated that the wear diameter and frictional coefficients of the system could be lessened obviously with the addition of TM. In the range of load 100 -500 N, the appropriate dosage of TM was 0.6%.关键词
