Abstract
A fluoroalcohol of the formula EQU Rf(CH.sub.2 CH.sub.2 OH)n (1) is prepared by the following three kinds of processes: PA0 (a) by contacting a betaine compound with a halide compound of the formula EQU Rf(CH.sub.2 CH.sub.2 X)n (2) PA0 to obtain an intermediate compound and subjecting the intermediate compound to hydrolysis, PA0 (b) by contacting a betaine compound and water in the presence of an organic solvent with a halide compound of the formula EQU Rf(CH.sub.2 CH.sub.2 X)n (2), or PA0 (c) by contacting a betaine type surfactant and water with a halide compound of the formula EQU Rf(CH.sub.2 CH.sub.2 X)n (2), PA0 wherein Rf is C.sub.2.about.13 fluoroalkyl or C.sub.2.about.13 fluoroalkylene group, X is iodine or bromine, n is 1 when Rf is fluoroalkyl group and n is 2 when Rf is fluoroalkylene group.
