Method for separating binary substituted benzene isomer mixture through liquid phase adsorption

The invention discloses a method for separating a binary substituted benzene isomer mixture through liquid phase adsorption, one or more of binary substituted benzene isomers can be separated according to different mixing proportions of two aluminum-based metal organic framework materials CAU-23 (Al) and MIL-160 (Al), and organic ligands of the aluminum-based metal organic framework materials are 2, 5-thiophenedicarboxylic acid, 2, 5-dithiophenedicarboxylic acid, 2, 5-dithiophenedicarboxylic acid, 2, 5-dithiophenedicarboxylic acid, 2, 5-dithiophenedicarboxylic acid, 2, 5-dithiophenedicarboxylic acid, 2, 5-dithiophenedicarboxylic acid and 2, 5-dithiophenedicarboxylic acid. And 2, 5-furandicarboxylic acid. By adopting the method disclosed by the invention, the binary substituted benzene isomer in the liquid phase can be effectively separated, the organic ligand and the metal salt required for preparing the aluminum-based metal organic framework material are cheap and easy to obtain, the synthesis conditions are
