Process for preparing fluoroalcohol |
| abstract |
A fluoroalcohol of the formula n n Rf(CH.sub.2 CH.sub.2 OH)n (1) n n is prepared by the following three kinds of processes: n (a) by contacting a betaine compound with a halide compound of the formula n n Rf(CH.sub.2 CH.sub.2 X)n (2) n n to obtain an intermediate compound and subjecting the intermediate compound to hydrolysis, n (b) by contacting a betaine compound and water in the presence of an organic solvent with a halide compound of the formula n n Rf(CH.sub.2 CH.sub.2 X)n (2), or n n (c) by contacting a betaine type surfactant and water with a halide compound of the formula n n Rf(CH.sub.2 CH.sub.2 X)n (2), n n wherein Rf is C 2 ˜13 fluoroalkyl or C 2 ˜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. |
