Abstract (en)
The oxidation-promoting effect of the overbased additives can be attenuated or even eliminated by incorporation into the overbased additive of a copper carboxylate originating from aliphatic carboxylic acids containing a linear or branched C7-C10 chain. These copper carboxylates can also be employed in the form of combination with a boron derivative.
Abstract (fr)
L'effet pro-oxydant des additifs surbasés peut être atténué ou même supprimé par incorporation dans l'additif surbasé d'un carboxylate de cuivre, issu d'acides carboxyliques aliphatiques à chaîne linéaire ou ramifiée en C7 à C10 . Ces carboxylates de cuivre peuvent également être utilisés sous forme d'association avec un dérivé du bore.
