Abstract
The present invention discloses a method of separating C8 aromatic hydrocarbon isomers. The anion-pillared metal-organic framework materials with a pore diameter of 5-10 Å is used as adsorbents to achieve selective adsorption and separation of C8 aromatic hydrocarbon isomers by contacting the C8 aromatic hydrocarbon isomers with the adsorbents; the anion-pillared microporous materials are porous materials formed by metal ion M, inorganic anion A and organic ligand L through coordination bonds, with the general formula of [MAL], where n>4 and n is an integer; the descried 'metal ion M' is Fe, Co, Ni, Cu; the descried “inorganic anion A” is SiF, NbOF, TaF, ZrF, TiF, GeF, SOCF, NbF; the descried “organic ligand L” is selected from any of the following:
