Abstract
MFI-type zeolites are synthesized with N-trimethoxysilylpropyl-N,N,N-t rialkylammonium (TAASi) salts using the composition SiO2:0.1TAASiBr:0. 25NaOH:40 H2O (molar ratios). Prehydrolysis of the organosilane precur sor is necessary for zeolite formation. Quantitative NMR spectra show that the majority of the organosilicon carbon-silicon bonds are cleave d in the as-synthesized zeolite. (C) 1997 Elsevier Science B.V.
