A zeolitic catalyst useful in the selective disproportionation and transalkylation of toluene comprises a molecular sieve having a pore diameter of about 5 to 8 &angst;, a refractory inorganic oxide and a reduced weak non-framework metal which is believed to provide Lewis acidity.

Selective aromatics disproportionation/transalkylation catalyst

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.
