Region of pH (7.4 - 11.4), favorable for the formation of UTL in the reaction media (MS), in which there are octamer anions SinGe8-nO15(OH)53- - prototypes of new construction units D4R was defined. It is shown that the introduction of electrondeficit elements to the frame of UTL leads to the formation of a large number of Brensted a.c., whose strength increases in the number of B <Fe <Ga <<Al. In the reaction of benzoylation of p-xylene catalytic activity of zeolites correlates with the concentration and strength of Brensted a.c.and increases in the number of UTL <B-UTL <Ga-UTL <Al-UTL. The conditions of obtaining, structural-sorption characteristics of micro-mesoporous materials based on products of fragmentation of zeolites MCM-22, H-ZSM-5, BEA were determined; their catalytic activity in the hydrocracking reaction of n-hexane correlates with the concentration of strong acid centers.
