Abstract

Disclosed is a method for easily recovering a high concentration fluorine-containing alcohol from a liquid mixture containing water and a fluorine-containing alcohol which is produced during production of CD-R or DVD-R. Specifically disclosed is a method for recovering a fluorine-containing alcohol which comprises a step for separating a liquid mixture containing water and a fluorine-containing alcohol such as 2,2,3,3-tetrafluoropropanol into two layers by adding an acid such as a sulfuric acid into the liquid mixture. More preferably, this method may further contain a distillation step for distilling the lower layer obtained in the two-layer separation step.
