ABSTRACT:
Crystalline zeolites and zeolitic materials are prepared by crystallization from an aqueous mixture comprising a source of silica, optionally a source of alumina, and an ion-exchange resin preferably an anion-exchange resin. In a preferred form of the invention the anion-exchange resin is in the hydroxide form and the reaction mixture also contains a quaternary ammonium compound.
