Firstly, stirring the mixed porous liquid, difluoroethanol and water, and standing to obtain two layered phases; separating the upper raffinate phase and the lower extract phase by a liquid separation mode. Then, carrying out back extraction on the lower extraction phase by using ethyl acetate, and rectifying the back extraction phase after back extraction to obtain difluoroethanol; and circularly extracting the upper raffinate phase by using regenerated porous liquid. The porous liquid used in the invention has the characteristics of both porous materials and ionic liquid, and has the advantages of high separation efficiency, strong circulating extraction capacity, environmental friendliness and reusability.)
