摘要
New class of templates, ethanolamine salts, was used to synthesize zeolites with the ZSM-12 structure. The materials obtained were characterized by methods of powder X-ray diffraction, scanning electron microscopy, IR spectroscopy, low-temperature adsorption-desorption of nitrogen, and elemental analysis. It was shown that, with these templates, it is possible to obtain crystallites with well formed acicular shape, hexagonal morphology, large surface area, and narrow pore size distribution.
