The effect of the SiO2/A1203 ratio of H-mordenite on shape-selective catalysis was studied in the isopropylation of naphthalene with propylene. Aluminum concentrations at intracrystalline and external surfaces of H-mordenite are not directly related to catalyst performances. Dealuminated H-mordenite
Levyne-type zeolites were synthesized from gels of initial compositions 4.5Na,O--6MeQIPsA120, 3OSiO,-SOOH,O. with MeQ =methylquinuclidinium and 0.6 5 I 2 3 at 150 5 t 2 190' C. The '"Si NMR spectra show the presence of two crystallographically different sites in the structure. The 27A1 NMR spectra a
