Abstract: New saturated fluoroalkylamines and carboxyalkylbetaines and alkylsulfobetaines derived therefrom, and mixtures containing the new fluoroalkylamines and mixtures containing the new fluorobetaines are described. The saturated fluoroalkylamines conform to the formula below in which n is an integer from 3 to 17 and R1 and R2 are C1 to C4-alkyl, C1 to C4-hydroxyalkyl or hydrogen, with the proviso that only one of the two substituents R1 and R2 is hydrogen. The carboxyalkylbetaines and sulfobetaines and the mixtures thereof are highly effective products for reducing the surface tension of water/air systems and the interfacial tension of water/hydrocarbon systems.

Abstract: New saturated fluoroalkylamines and carboxyalkylbetaines and alkylsulfobetaines derived therefrom, and mixtures containing the new fluoroalkylamines and mixtures containing the new fluorobetaines are described. The saturated fluoroalkylamines conform to the formula below (see formula I) in which n is an integer from 3 to 17 and R1 and R2 are C1 to C4-alkyl, C1 to C4-hydroxyalkyl or hydrogen, with the proviso that only one of the two substituents R1 and R2 is hydrogen. The carboxyalkylbetaines and sulfobetaines and the mixtures thereof are highly effective products for reducing the surface tension of water/air systems and the interfacial tension of water/hydrocarbon systems.

Abstract: HOE 89/F 920 of the disclosure: Urethanes made from aliphatic fluoro alcohols, isocyanates and carboxylic acids, a process for their preparation and their use The urethanes described are synthesized from aliphatic fluoro alcohols, triisocyanate and a carboxylic acid. They are prepared by reaction of the aliphatic fluoro alcohol with the triisocyanate to give the fluoro alcohol/triisocyanate adduct and by reaction of this adduct with the carboxylic acid. The new urethanes are preferably used for the finishing of textiles for the purpose of achieving water, oil and soil repellency.

Abstract: HOE 91/F 908 of the disclosure Process for the preparation of primary and secondary fluorine-containing alcohols A process is described for the preparation of fluoroalcohols of the formula below Rf-CH2-CH2-?H-OH in which Rf is a perfluoroalkyl radical having 1 to 20 carbon atoms and R is hydrogen or an alkyl radical having 1 to 5 carbon atoms, by reaction of a perfluoroalkylethylene, Rf-CH=CH2, and an n-C1 to C6-alkanol in the presence of a free radical initiator, the perfluoroalkylethylene, the alkanol and the free radical initiator being used in the molar ratio of 1 to 20-50 to 0.002-0.2. In the novel process, in addition, the reaction is carried out in a specific manner and under specific reaction conditions. The fluoroalcohols given are obtained in high yield.

Abstract: 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.
