Title:

PROCESS FOR PRODUCING FLUORINATED ALCOHOL

Document Type and Number:

WIPO Patent Application WO/2003/004446

Kind Code:

A1

Abstract:

A process for producing a fluorinated alcohol from a fluoroalkyl halide through a one−stage reaction in high yield with high selectivity without using a highly toxic compound such as a heavy metal compound, which is difficult to handle or treat. The process, which is for producing a fluorinated alcohol represented by the general formula (2): Rf(A)OH (2) (wherein Rf represents C₁₋₁₀ perfluoroalkyl and A represents a C₃₋₁₀, linear or branched, saturated hydrocarbon group), is characterized by reacting a fluoroalkyl halide represented by the general formula (1): Rf(A)X (1) (wherein Rf and A are the same as defined above and X represents halogeno) with an alkali metal salt of 4−hydroxybutyric acid in &gammad −butyrolactone as a solvent.
