The present invention provides a method of solubilising in an aqueous medium a hydrocarbon or a hydrophobic compound having a hydrocarbon skeleton that carries one or more heteroatom- containing functional groups, e.g. hydroxyl, car-boxylic acid or aldehyde (CHO) groups. The method comprises contacting the hydrocarbon or the hydrophobic compound with the aqueous medium that includes at least one non-ionic surfactant containing a hydrophilic part and a hydrophobic part, the hy-drophilic part comprising a polyhydroxylated moiety and the hydrophobic part comprising a hydrocarbon chain containing at least 12 carbon atoms, e.g. ethoxylated sorbitol. The amount of surfactant used is sufficient to form micelles including a core formed of the hydrocarbon or the hydrophobic compound.
La présente invention porte sur un procédé de solubilisation dans un milieu aqueux d'un hydrocarbure ou d'un composé hydrophobe ayant un squelette hydrocarboné qui porte un ou plusieurs groupes fonctionnels contenant un hétéroatome, par exemple des groupes hydroxyles, acides carboxyliques ou aldéhydes (CHO). Le procédé comprend la mise en contact de l'hydrocarbure ou du composé hydrophobe avec le milieu aqueux qui comprend au moins un agent tensioactif non ionique contenant une partie hydrophile et une partie hydrophobe, la partie hydrophile comprenant une fraction polyhydroxylée et la partie hydrophobe comprenant une chaîne hydrocarbonée contenant au moins 12 atomes de carbone, par exemple le sorbitol éthoxylé. La quantité de tensioactif utilisé est suffisante pour former des micelles comprenant un cur formé de l'hydrocarbure ou du composé hydrophobe.
