Abstract (en)
Overbased detergent for lubricating oils, obtained by carbonation of a mixture containing a detergent chosen from alkali or alkaline-earth metal sulphonates, naphthenates, salicylates, phosphonates and thiophosphonates, an alkali or alkaline-earth metal oxide, hydroxide or alcoholate, a nitrogenous and/or oxygen-containing promoter, at least 3 % by weight of phosphorus in the form of a nonmetallic organic derivative, a hydrocarbon solvent and optionally a diluent oil and water. These detergents contain 0.5 to 10 % and preferably 1 to 5 % by weight of phosphorus. They have greatly improved antiwear and antioxidant properties.
