Multifunctional composite additives to the lubricants
S.M. VeliyevaOn the basis of the mixture of sulphomethylated technical alkyl-salicilic acids and condensation product of technical alkylphenol, the base and average-alkali salicilate-sulphonat additives have been synthesized with formaldehyde. Developed composite additives have multifunctional properties. Adding them into M-11 oil at 5 % concentration significantly improves their washing, dispersive and anticorrosion properties, increases stability against oxidizing and by efficiency exceeds MACK alkyl-salicylic and Hightech 6060M sulphonate additives. Using synthesized average alkali additive, М-10Г2 type motor oil by its quality indexes corresponding to the specified requirements has been developed.
