Method for efficiently inducing phase separation of water-organic solvent mixed solution through inorganic salt

Abstract

The present disclosure provides a method for efficiently inducing phase separation of a water-organic solvent mixed solution through an inorganic salt, comprising the following steps: A) adding the inorganic salt to the water-organic matter mixed solution, sonicating and then allowing to stand for complete dissolution of the inorganic salt, wherein the water-organic matter mixed solution is a water-acetonitrile mixed solution or a water-acetone mixed solution; the inorganic salt is one or more of LiCl, NaCl, KCl, CsCl, NaBr, KBr, Li2SO4, Na2SO4 and MgSO4; B) allowing the solution obtained in the step A) to stand in a constant temperature environment until phase separation is completed to obtain a product.
