FIELD: chemistry.
SUBSTANCE: method involves the following steps. Providing a mixture containing one or more sources of YO2, one or more sources X2O3, and one or more tetraalkylammonium cation containing R1R2R3R4N+ compounds as guide agents for the formation of the structure and crystallization of the resulting mixture. Y is a tetravalent element, X is a trivalent element. The initial mixture contains seed crystals and does not contain a source of phosphorus. Tetraalkylammonium cations R1R2R3R4N+ compounds are composed of one or more N,N,N-trimethylcycloalkylammonium compounds.
EFFECT: economical way to produce a zeolitic material with catalytic activity.
