Effect of Template Structure on the Zeolite ZSM-12 Crystallization Process Characteristics

Kulikov, L. A. / Tsaplin, D. E. / Knyazeva, M. I. / Levin, I. S. / Kardashev, S. V. / Filippova, T. Yu. / Maksimov, A. L. / Karakhanov, E. A.

Characteristics of zeolite ZSM-12 crystallization using methyltriethylammonium chloride and N,N-dimethyl-N-ethyl(monoethanol)ammonium bromide as templates have been studied. The materials have been characterized by X-ray diffraction analysis, scanning electron microscopy, X-ray fluorescence analysis, low-temperature nitrogen adsorption–desorption, temperature-programmed desorption of ammonia, and solid-state ²⁷Al nuclear magnetic resonance spectroscopy. It has been shown that dimethylethylethanolammonium bromide inhibits crystal growth along the a and c planes and thereby contributes to crystal growth only in the direction of the b axis, which, in turn, leads to lower surface area and acidity of the sample than the respective parameters of the zeolite synthesized using methyltriethylammonium chloride.
