Abstract (en)
Overbased alkali metal or alkaline-earth metal phenate obtained by carbonation of a mixture containing a phenolic compound, an organic phosphorus derivative, a derivative of an alkali metal or alkaline-earth metal, a nitrogenous and/or oxygen-containing promoter, a hydrocarbon solvent and optionally a diluent oil and water. The incorporation of the phosphorus during the carbonation makes it possible to avoid the negative interactions between overbased phenates and organic phosphorus derivatives.
Abstract (fr)
Phénate alcalin ou alcalinoterreux surbasé obenu par carbonatation d'un mélange contenant un composé phénolique, un dérivé organique du phosphore, un dérivé d'un métal alcalin ou alcalinoterreux, un promoteur azoté et/ou oxygéné, un solvant hydrocarboné et éventuellement une huile diluante et de l'eau. L'incorporation du phosphore pendant la carbonatation permet d'éviter les interactions négatives entre phénates surbasés et dérivés organiques du phospore.
