Abstract

A method for selectively separating 2,6-dichlorotoluene from a mixture of dichlorotoluene isomers by means of a zeolite adsorber, characterized in that a zeolite selected from the group consisting of ZSM-5 zeolite, ZSM-8 zeolite, ZSM-11 zeolite, ZSM-21 zeolite, ZSM-35 zeolite, Zeta-1 zeolite, Zeta-3 zeolite and TPZ-3 zeolite, is used as the adsorber to selectively separate 2,6-dichlorotoluene as a non-adsorbed component.
