CA 2640295
The invention relates to the use of mixtures of: A) aliphatic saturated or unsaturated monocarboxylic acids with 12 to 24 carbon atoms or the dimerised or trimerised products, ammonium salts, amides, esters or nitriles thereof and B) polycyclic hydrocarbon compounds made from distillation residues of natural oils extracted from tree resins, for improving the storage stability of fuel additive concentrates comprising at least one detergent and at least one cetane number improver, wherein said mixtures are applied with a concentration of 0.7 to 20 wt. %, relative to the total amount of fuel additive concentrate.
L'invention concerne l'utilisation de mélanges contenant A) des acides monocarboxyliques aliphatiques saturés ou insaturés comportant 12 à 24 atomes de carbone ou leurs produits de dimérisation ou de trimérisation ou bien leurs sels d'ammonium, amides, esters ou nitriles, ainsi que B) des composés d'hydrocarbures polycycliques obtenus de résidus de distillation d'huiles naturelles extraites de résines d'arbres, pour améliorer la stabilité au stockage de concentrés d'additifs de carburants contenant au moins un détergent et au moins un améliorant d'indice de cétane, ces mélanges étant utilisés en un concentration de 0,7 à 20 % en poids, relativement au volume total du concentré d'additifs de carburants.
