Proton-loaded zeolites. 1. HX (X = Cl, Br, I) in sodium zeolite Y archetype: Packaged acids on the rod to intrazeolite semiconductors
- Univ. of Toronto, Ontario (Canada)

This series of three papers is concerned with an in-depth investigation of proton-loaded zeolites (packaged acids), a novel class of controlled microporosity, solid-state Broensted acids. Proton-loaded zeolites are formed from the reaction between anhydrous Broensted acids and dehydrated zeolites. Initial experiments focus attention on the chemistry, spectroscopy, diffraction, and dynamics of the sorption and desorption of anhydrous hydrogen halides (HX) in zeolite Y with some important control experiments in all-silica zeolite Y (SiO{sub 2}-Y) and ALPO-5. Zeolite cation, HX anion, H/D isotope, and probe-base effects are explored to elucidate details of location, population, distribution (homogeneity), thermal/kinetic stability, acidity, and reactivity of protonation, anionation, and solvation sites in the zeolite Y lattice.
