Process for preparing fluoroalcohol

摘要

A fluoroalcohol of the formula Rf(CH2CH2OH)n(1) is prepared by the following three kinds of processes: (a) by contacting a betaine compound with a halide compound of the formula Rf(CH2CH2X)n(2) to obtain an intermediate compound and subjecting the intermediate compound to hydrolysis, (b) by contacting a betaine compound and water in the presence of an organic solvent with a halide compound of the formula Rf(CH2CH2X)n(2), or (c) by contacting a betaine type surfactant and water with a halide compound of the formula Rf(CH2CH2X)n(2), wherein Rf is C2 DIFFERENCE 13 fluoroalkyl or C2 DIFFERENCE 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.
