Titanium dithiophosphates: A new class of multifunctional lubricant additives
- Indian Oil Corporation, Faridabad (India); and others
Three oil-soluble trisopropoxytitanium dialkyphosphorodithioates and an oil-insoluble diisopropoxytitanium alkylenephosphorodithioate were synthesized in nearly quantitative yields. These titanium complexes were evaluated for their antifriction, extreme pressure, antiwear and antioxidant properties in lubricating base oils and greases. The results show that at 0.5% w/w level, these complexes reduce the coefficient of friction by 20 to 25 percent, increase weld load by 45 to 110 percent, decrease metallic wear by 25 to 45 percent and considerably improve resistance of oil towards oxidation. The performance of these newly developed multifunctional additives has been compared with commercially established additives like molybdenum dithiophosphates and zinc dithiophosphates. 23 refs., 5 figs., 7 tabs.
