Method for solubilising asphaltenes in an asphaltenes-containing hydrocarbon mixture by adding thereto an effective amount of a dendrimeric compound, and a hydrocarbon mixture comprising, in addition to hydrocarbons, asphaltenes and at least one dendrimeric compound. Preferably, the dendrimeric compound is a hyperbranched polyester amide, more preferably a polyester amide built up from succinic anhydride, diisopropanolamine, functionalised with poly (isobutenyl) succinic anhydride.

Procédé de solubilisation d'asphaltènes dans un mélange d'hydrocarbures renfermant des asphaltènes, qui consiste à ajouter à ce mélange une quantité efficace d'un composé dendrimère ; et mélange d'hydrocarbures renfermant, outre les hydrocarbures, des asphaltènes et au moins un composé dendrimère. Le composé dendrimère est de préférence un polyester amide hyperramifié, mieux encore un polyester amide fabriqué à partir d'anhydride succinique, de diisopropanolamine et fonctionnalisé par réaction avec de l'anhydride poly(isobutényl) succinique.
