Title: Method for manufacturing fluoroalcohol

Abstract: The invention relates to a method for manufacturing a fluoroalcoholrepresented by formula (1)(wherein R.sup.1 represents F or CF.sub.3, when n=1; R.sup.1 represents F,when n=2) by reacting methanol with tetrafluoroethylene orhexafluoropropylene in the presence of a free radical generator, whereinthe method comprises the steps of: feeding a reaction mixture into adistillation column; distilling off methanol from the top of thedistillation column; withdrawing a bottom fraction comprising thefluoroalcohol from the bottom of the distillation column; removing afraction comprising water and HF from the distillation column by side cut;feeding methanol from the top of the distillation column back into areactor for recycling; and purifying the bottom fraction to recover thefluoroalcohol represented by formula (1).
