Crystallization of Zeolites in the Presence of Diquaternary Alkylammonium Salts Derived from Dimethylethanolamine

Zeolite-containing materials of various structural types (MFI, MEL, MTW) were prepared by the hydrothermal method using organic templates based on quaternary polymethylenediammonium salts. The materials were characterized by X-ray diffraction analysis, low-temperature nitrogen adsorption–desorption, temperature-programmed ammonia desorption, IR spectroscopy, scanning electron microscopy, X-ray fluorescence analysis, transmission electron microscopy, solid-state 27 Al NMR spectroscopy, and IR spectroscopy of adsorbed pyridine. The effect of the template on the structure of the material obtained was revealed.
