Abstract
PURPOSE: To separate the titled isomer economically in separating a halogenated toluene isomeric mixture with a zeolite adsorbent, by using a desorbing agent consisting of an aromatic alkyl hydrocarbon as an essential component.
CONSTITUTION: A halogenated toluene isomeric mixture (B) is separated with a zeolite adsorbent by using a desorbing agent (D) consisting of an aromatic alkyl hydrocarbon, i.e. a monocyclic aromatic alkyl hydrocarbon having 1W4 substituent groups of 1W3C alkyl groups in the benzene nucleus, preferably toluene, ethylbenzene or m-xylene, as an essential component. The adsorbent has a high selective adsorptivity [α(A/B) of the formula] for the isomeric mixture (B) and a selective adsorptivity [α(A/D) of the formula] of the strongly adsorbed component (A) for the desorbing agent (D) close to 1. The isomer can be continuously and economically separated by repeating the adsorbing and desorbing operations with the desorbing agent (D).
