(Studies of the Fundamental Nature of Catalytic Acidity, Sites, and Intermediates): Progress Report.

摘要

Advances in the understanding of the acidic and catalytic properties of H-zeolites have been achieved from several kinds of experiments. These included: (1) MASNMR studies of adsorbed alcohols, (2) optical spectroscopy of Hammett indicators, (3) studies of the kinetics and mechanisms of the catalytic decomposition of isobutane and neopentane, (4) site poisoning experiments using NH3, and (5) preparation and characterization of dealuminated zeolites by (29)Si and 27(Al)MASNMR, (1)H-NMR, x-ray diffraction and physical adsorption.
