Abstract

In order to expand the range and efficiency of sulfonate additives the possibility of obtaining  on the basis sulfomethylated dialkylphenols, synthesized by repeated alkylation of technical nonyl phenol and alkyl (C8-C12) phenol by the ethylene oligomer of fraction (C10-C14) was investigated.
Developed basic and medium alkaline calcium hydroxydialkylbenzylsulfonates are completely soluble in vase oils, are  haracterized by good physicochemical and functional properties and by quality indicators slightly differ among themselves. Being the additives of multifunctional action they vastly improve the detergent, dispersant, anti-corrosive properties and stability against oxidation  of lubricating oils and by efficiency exceed foreign analogue- Hightech 6060M additive.
