SURFACE-ACTIVE COMPOUNDS HAVING A PERFLUOROALKYL GROUP AND A NITROGEN-CONTAINING ALIPHATIC RADICAL, A PROCESS FOR THEIR PREPARATION AND THEIR USE

摘要

HOE 89/F 921 of the disclosure: Surface-active compounds having a perfluoroalkyl group and a nitrogen-containing aliphatic radical, a process for their preparation and their use The new compounds have the formula below in which Rf is a perfluoroalkyl radical having 4 to 20 carbon atoms, x is 1 to 4, y is 1 to 10, X is Br, Cl or I, and R1 and R2 are hydrogen or a C1 to C4-alkyl radical or a water-solubilizing aliphatic radical, with the proviso that at least one of the two substituents and R2 is a water-solubilizing aliphatic radical. The surface-active compounds described are prepared by reacting a suitable epoxide with a suitable amine. They are used in particular for the preparation of foaming agents.
