Zusammenfassung:	UTILISATION D'AMINES GRASSES DE FORMULE GENERALE:(CF DESSIN DANS BOPI)OU R EST SOIT UN ATOME D'HYDROGENE, SOIT UN RADICAL ALKYLE LINEAIRE OU RAMIFIE, SATURE, COMPRENANT DE 4 A 18ATOMES DE CARBONE ET OU R REPRESENTE UN RADICAL ALKYLE LINEAIRE OU RAMIFIE, SATURE, COMPRENANT DE 4 A 18ATOMES DE CARBONE CONJOINTEMENT AVEC DES AGENTS DE SURFACE, POUR OBTENIR DES MELANGES MOUSSANTS CONDUISANT A DES MOUSSES AMELIOREES.ON AJOUTE 2 A 50 D'AMINES, PAR RAPPORT AU POIDS DES AGENTS DE SURFACE.APPLICATION DANS LE DOMAINE DES MOUSSES EXTINCTRICES, DE FORAGE, POUR LA FABRICATION DE PRODUITS ALLEGES. Use of fatty amines of general formula: wherein R1 may be a hydrogen atom, or a straight or branched alkyl radical, saturated and containing 4 to 18 atoms of carbon and wherein R2 is a straight or branched alkyl radical, saturated and containing 4 to 18 atoms of carbon, together with surface agents, to obtain foaming mixtures leading to improved foams. 2 to 50% amines are added, with respect to the weight of the surface agents. Application in the field of fire extinguishing foams, drilling, and in the production of lightweight products.
