ABSTRACT:
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.
