Реферат:
Beryllium silicates having the ZSM-5-type crystalline structure were synthesized in the presence of tetraethylammonium hydroxide. The chemical shifts in the 9Be NMR spectra show that Be2+ cations in these synthesized samples are located in a tetrahedral coordination different from that for Be2+ in BeO and [Be(H2O)4]2. Methanol conversion on beryllium-silicate zeolites yields primarily olefins, while on aluminum silicates having the same crystalline structure paraffins and aromatic hydrocarbons were obtained. It is proposed that the observed differences in the catalytic action result from the lower strength and concentration of Lewis acid sites in the composition of catalytically active groups in beyllium silicates.
