STRONTIUM CONTAINING SULPHONATES ON THE BASIS OF ALKYLPHENOL AS MULTIFUNCTIONAL ADDITIVES FOR LUBRICATING OILS

Based on sulphomethylated alkyl(C25–C30)phenol new modifications of sulphonate type additives-strontium hydroxyalkylbenzylsulphonate have been synthesized and studied. Developed base and medium alkaline sulphonates are characterized by their high physico-chemical and functional properties and exceed foreign analogue – Hightech 6060M additive. Being the additives of a broad spectrum they significantly improve the detergent-dispersant, anti-corrosion properties, stability against oxidation of base oil and also possess high thermal stability. Using given medium alkaline additive the test M-10 Г2k motor oil have been developed which in term of quality meets the requirements
