MODIFIED SULFONATE ADDITIVESTO THE LUBRICATING OILS
For widening assortment and efficiency of sulphonated additives the possibility of their preparation on the base of aminomethylated technical nonylphenol and alkyl(C8-C12)phenol was investigated. For the first time the synthesized highalkaline nitrogencontaining sulphonates of calcium CC-300SN1 and CC-300SN2 quitly are soluble in oil, they are characterized by high physica-chemical and functional properties and by indexes of quality slightly differ. Being additives of multifunctional action at introduction of them into oil M-11 in concentration of 5% considerably improve detergent, dispersant, anticorrosive, antiwear properties and stability against oxidation. The procces of preparation of the developed highalkaline additives is ecologically secure and wasteless because there are no usage of agressive sulphonated agents and formation of acid tar which are necessary conditions for production of sulphonated additives.
