Beschreibung
Zusammenfassung:	The invention discloses a method for separating o-methyl-ethylbenzene and m-methyl-ethylbenzene, which is characterized in that a bis (dibromoethoxy) pillar [6] arene crystal material is used as an adsorbent, and a mixture containing o-methyl-ethylbenzene and m-methyl-ethylbenzene is contacted and adsorbed with the adsorbent to realize the separation of o-methyl-ethylbenzene and m-methyl-ethylbenzene, the chemical structural formula of the bis (dibromo ethyoxyl) pillar [6] arene crystal material is shown in the specification. The invention also discloses application of the bis (dibromo ethyoxyl) pillar [6] arene crystal material in selective adsorption and complexation of o-methyl-ethylbenzene in a mixture containing o-methyl-ethylbenzene and m-methyl-ethylbenzene to realize separation of o-methyl-ethylbenzene and m-methyl-ethylbenzene. The separation process is simple to operate and low in equipment requirement; rectification operation is not needed in the separation process, energy consumption is low, energ
