Abstract
An improved process is disclosed for the selective disproportionation of toluene. The process uses a zeolitic catalyst which is oil-dropped in an amorphous aluminum phosphate binder and optionally is selectively precoked prior to toluene disproportionation. The catalyst and process provide enhanced selectivity for the production of paraxylene.
