Abstract
For a series of metal aluminophosphate zeolites with the VFI structure it was established that the cations of alkaline-earth and transition metals are mostly included isomorphously at the octahedral positions of the framework with substantial deformation of the structure. The strength of the Brönsted acid centers decreases greatly in the series of substituent cations Mg >> Ca > Sr ≥ Ba and increases in the series Cu ≤ Ni ≤ Mn < Co < Zn < Cr < Mg. This is probably determined by the combined effect of the electronegativity and the radius of the metal cation on the Me-O(H)-P bond angle and the strength of the acid centers.
