STRONTIUM CONTAINING SULFONATES ON THE BASIS OF ALKYLPHENOL AS MULTIFUNCTIONAL ADDITIVES FOR LUBRICATING OILS
Based on sulfomethylated alkyl (C25–C30) new modifications of sulfonate type additives - strontium hydroxyalkylbenzylsulfonate have been synthesized and studied. Developed base and medium alkaline sulfonates 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 G2k motor oil have been developed which in term of quality meets the requirements.
