摘要： A process for producing a high-purity fluorinated alcohol in a good purification yield, is provided.In a process for producing a fluorinated alcohol, which comprises reacting methanol with tetrafluoroethylene or hexafluoropropylene in the presence of an alkyl peroxide, the reaction liquid after completion of the reaction is distilled in the presence of water and HF to separate it into a fraction containing an alcohol derived from the alkyl peroxide and a bottom liquid containing the fluorinated alcohol, and then, the bottom liquid is purified to recover the fluorinated alcohol.
