HOE 91/F 908 Abstract of the disclosure Process for the preparation of primary and secondary fluorine-containing alcohols A process is described for the preparation of fluoro- alcohols 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 perfluoroalkyl- ethylene, Rf-CH=CH2, and an n-C1 to C6-alkanol in the presence of a free radical initiator, the perfluoro- alkylethylene, 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.
