Abstract (en)

[origin: EP0383359A2] Process for preparing a superalkalfied additive containing inorganic boron by carbonation of a reaction mixture consisting of a detergent, an alkali metal or alkaline-earth metal and nitrogen- containing and oxygen-containing promoters in a diluent oil and a hydrocarbon solvent. The inorganic boron derivative is introduced into the reaction mixture before the carbonation reaction. The boron additive is employed as an additive with an antiwear effect in lubricants.
