Products Description
Introduction and application of CAS:59656-20-1|2,5-bis(tert-dodecyldithio)-1,3,4-thiadiazole
Metal deactivator T561 is a thiadiazole polysulfide. This product is a corrosion inhibitor for copper and a deactivator for non-ferrous metals. It has excellent oil-soluble properties and can be used as a metal deactivator in lubricating oils. It can capture active sulfur in oil, inhibit metal corrosion, and has good extreme pressure and anti-wear properties. The synthesis process of this product avoids the use of ionic strong acid. Select the appropriate ingredients to produce a product with higher active sulfur content and lower acid value. Because it contains polysulfide bonds, it can form a sulfide film with the metal surface, thereby effectively It inhibits the catalytic effect of metal ions on oil products, so T561 is a very effective lubricating oil additive in terms of improving the performance of oil products. In the alkaline high-zinc anti-wear hydraulic oil formula, adding 0.03-0.05% T561 metal deactivator can significantly reduce ZDDP (zinc dialkyl dithiophosphate), T705 (barium dinonylnaphthalene sulfonate) ) Regarding the corrosion and hydrolysis stability of copper, the oil can pass the Denison HF-2 hydrolysis stability test. In the internal combustion engine oil formula, adding 0.4-0.5% T561 metal deactivator can increase the TFOUT induction period of the oil by more than 60 minutes. In addition, T561 metal deactivator can also be used in industrial gear oil and high-quality gasoline engine oil: when used in internal combustion engine oil, it can greatly improve the antioxidant performance of Daqing paraffin-based oil; when used in two-stroke gasoline engine oil, it can improve the quality of the oil. Anti-bulging performance. Experiments show that T561 is a sufficient sulfur storage source and can react with active sulfur to generate non-corrosive polysulfide compounds, which has the unique function of capturing active sulfur.
