Abstract
A process is described for the isomerization of chlorotoluenes by contact of ortho-chlorotoluene or para chlorotoluene, in liquid phase and under reaction conditions, with a solid catalyst obtained by exchange between the acid form of a ZMS-5 zeolite and a salt of an alkali, alkaline-earth, group three or transition metal.
