SYNTHESIS AND INVESTIGATION OF MULTIFUNCTIONAL SULPHONATE ADDITIVES TO LUBRICATINQ OILS
S.M.Veliyeva, A.N.Agayev, I.D.Kulaliyev

 

On the base of the product of sulphomethylation of sulphureted alkyl(C15–C21)phenol the new modifications of additives of sulfonate type-thio-bis-hydroxyalkylbenzylsulfonates of calcium were synthesized and characterized. The developed neutral and average alkaline sulphonates have high physico-chemical and functional properties and by indices excel the well-known trade additives C-150 and Hitec 6060М. With the use of the obtained average alkaline additive in the quantity 1.6% the experimental motor oil M-12 BБ was developed that meets all reguirements.

 

Keywords : multifunctional additives, sulfomethylation, sulfurized alkylphenol, sulfonates of various alkalinity, func­tional properties, motor oil M-12 BБ
