Patent ID: 6894196

Claim:
A process for producing a fluorinated alcohol, which comprises: reacting methanol with tetrafluoroethylene or hexafluoropropylene in the presence of an alkyl peroxide to produce a fluorinated alcohol of the following formula (1) in a reaction liquid: H(CFR 1 CF 2 ) n CH 2 OH (1) wherein n is 1 or 2, and when n is 1, R 1 is F or CF 3 , and when n is 2, R 1 is F, distilling the reaction liquid after completion of the reaction in the presence of water and HF to separate into a fraction containing an alcohol derived from the alkyl peroxide and a bottom liquid containing the fluorinated alcohol of the formula (1), and then, purifying the bottom liquid to recover the fluorinated alcohol of the formula (1); wherein an evaporation residue of the fluorinated alcohol is at most 50 ppm.
