โœฆ Synopsis


Nuclear magnetic resonance spectra of aluminium mcludtig magic-angle spinning (27Al MAS NMR) have been m-red in order to study the dealumination which 1s caused by a heat treatment of zeolite CaA. The extra-lattice alummium edits partly in the form of Al(OH), anions, corresponding to at most about 17% of lattice dealuroination.

The hypothesis that the resolution of \*%i magic-angle-spinning NMR spectra of zeolite ZSM-S/silicalite is governed by tetrahedral Al content is questioned by showing that the introduction of substantial amounts of framework Al into silicalite does not impair spectral resolution. Possible alternativ
