Реферат:
The possibility of isomorphous heterocharged substitution (IHS) of Si4+ by Men+ cations of elements of Groups I – VIII (where n ≠ 4) in crystalline non-aluminium silicates with the ZSM structure has been examined. The silicates were synthesized in hydrothermal conditions in the presence of Men+ and tetrabutylammonium bromide. The catalytic activity of the silicates in methanol conversion into hydrocarbons has been determined. The state of Men+ in crystallization products was studied by EPR and NMR methods. As shown, the probability of Men+ fixation in tetrahedral oxygen surroundings in the silicate framework can be predicted on the basis of the Pauling criterion. Acid-base catalytic activity was found only for silicates with Men+ cations in IHS positions. Both the rate and selectivity of methanol conversion to hydrocarbons depend on the e/r of cations, because the number of Men+ which can be occluded in the IHS positions in the silicate framework depends on this parameter.
