摘要:
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.

摘要:
A process is described for the preparation of fluoroalcohols of the formula below ##STR1## in which R.sub.f 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, R.sub.f --CH.dbd.CH.sub.2, and an n-C.sub.1 to C.sub.6 -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.
摘要:
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 ##STR1## in which n is an integer from 3 to 17 and R.sup.1 and R.sup.2 are C.sub.1 to C.sub.4 -alkyl, C.sub.1 to C.sub.4 -hydroxyalkyl or hydrogen, with the proviso that only one of the two substituents R.sup.1 and R.sup.2 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.
