Organic water-containing mixture dehydration purification method

The invention discloses an organic water-containing mixture dehydration purification method and belongs to the technical field of organic material preparation. According to the method, a high purity micro-water organic material is prepared through circulation inert gas as a carrier and a closed circulation system of inert gas humidification, desorption regeneration, gas phase adsorption separation and low temperature condensation, and two or more parallel adsorption tank cyclic switching realizes desorption regeneration and gas phase adsorption separation. The method is especially suitable for dehydration of azeotrope of water and organic matters such as methyl acetate or isopropanol, solves the problem that dehydration purification is not finished by distillation because of azeotropy and the traditional pure liquid phase adsorption dehydration method has large energy consumption and a short adsorbent life, and provides a treatment process with the advantages of no gas phase discharge, environmental friendlin
