Resumo
New dialkyldithio derivatives of 2,6-dimethylphenol have been synthesized and characterized. For the first time, the polyfunctional properties of these compounds have been studied as additives to lubricating oils in the processes of friction and wear in the boundary friction regime, as inhibitors of high-temperature oxidation of hydrocarbons, and as protectors of metal surfaces. It has been established that already with the content of synthesized additives in lubricating oils in the amount of 0.5 wt. % antiwear properties are improved more than twice. It has been shown that additives exhibit a complex antioxidant effect and high efficiency at all stages of the oxidation process, and even at ultra-low concentrations (0.005 wt. %), their ability to resist oxidation exceeds widely used analogs. New additives are of considerable interest to modern lubrication science, and they can be used in motor oil compositions and other lubricants.
