Amine phosphate containing a terminal imide ring resulting from the reaction, under conditions for forming an amine salt, of at least one phosphate corresponding to the general formula (I): in which n is equal to 1 or 2, R is a divalent hydrocarbon group containing from 1 to 32 carbon atoms, R denoting a hydrogen atom or a hydrocarbon group which usually contains from 1 to 200 carbon atoms, with at least one amine. Process of preparation by conventional methods and use of these compounds as additives in fuels for engines, if appropriate in formulations containing a second constituent consisting of at least one product chosen from additives for nucleating paraffin waxes, it being possible for these formulations additionally to contain at least one product for inhibiting the growth of paraffin wax crystals. Phosphate d'amine comportant un cycle imide terminal résultant de la réaction, dans des conditions de formation d'un sel d'amine, d'au moins un phosphate répondant à la formule générale (I): dans laquelle n est égal à 1 ou 2, R¹ est un groupe hydrocarboné divalent ayant de 1 à 32 atomes de carbone, R représentent un atome d'hydrogène ou un groupe hydrocarboné ayant habituellement de 1 à 200 atomes de carbone, avec au moins une amine. Procédé de préaparation selon des méthodes classiques et utilisation de ces composés comme additifs dans les caburants pour moteurs, le cas échéant dans des formulations contenant un second constituant consistant en au moins un produit choisi parmi les additifs de germination des paraffines, ces formulations pouvant comprendre en outre au moins un produit inhibiteur de croissance des cristaux de paraffines.
