ABSTRACT:
An improved process is disclosed for the selective disproportionation and transalkylation of toluene. The process uses a zeolitic catalyst, preferably comprising a binder, containing a weak metal in a defined reduced state which is believed to provide Lewis acidity in the catalyst. The catalyst and process provide improved selectivity for the production of paraxylene.
