A process for separating dichlorotoluene isomers from a mixture containing at least two dichlorotoluene isomers comprising (a) passing said mixture containing dichlorotoluene isomers through a mordenite having the following composition; in molar ratios: a H2O: b M2/nO: Al2O3: (10-400 SiO2) in which M is hydrogen or at least one cation selected from an alkali metal or an alkaline-earth metal with the exception of cesium and rubidium, n is the valence of M, 0.7</=a+b</=1.1, and 0</=b</=0.2, (b) separating the non-adsorbed dichlorotoluenes from said mordenite, (c) contacting said mordenite containing the adsorbed isomers with a desorbent capable of separating said isomers from said mordenite, and (d) separating the desorbed isomers from the desorbent. |
