Abstract

The synthesis of zeolite UZM-8 with disordered MWW monolayers in the presence of diethyldimethylammonium hydroxide as the sole structure-directing agent is described. Under the synthesis conditions studied here, crystallization of pure UZM-8 was possible only from synthesis mixtures with a narrow range (15–25) of Si/Al ratios. The physicochemical properties of H-UZM-8 and its catalytic properties for the isopropylation of benzene to form cumene are compared with those obtained from the other members of MWW family of zeolites, i.e., H-MCM-22, H-ITQ-2, and H-MCM-56 with similar Si/Al ratios.
