Abstract

Hexamethyltienzene (HMB), adamantane, and naphthalene are adsorbed into zeolite Na-Y by a vapor phase impregnation method. Results from thermogravimetric analyses, Raman, and 13 C NMR measurements indicate that the organic species reside in the supercages of Na-Y. Proton multiple-quantum NMR spectroscopy is used to investigate the distribution of the organic species adsorbed within the cavities of Na-Y and the organic species occluded during the synthesis process into the intracrystalline voids of thecubic and hexagonal polytypes of faujasite and ZSM-18
