抄録
In an attempt to prepare zeolites of a new type or those having new surface properties, their synthesis in a nonaqueous solvent system using methanol, 2-propanol, ethylene glycol or monoethanolamine was studied. Sodalite of high crystallinity was obtained using monoethanolamine as solvent, and tetraethoxysilane, aluminum triisopropoxide, and sodium hydroxide as raw materials. The synthesis conditions were SiO2/Al2O3=2, Na2O/SiO2=5, solvent/Na2O=90 molar ratio at 150°C, and 22-490h of aging time. The properties of these crystals were compared with those obtained from 2-propanol containing water (1.2 vol% of solvent) and from pure water. Our crystals had a slightly larger lattice constant and adsorbed a large amount of N2 gas; in particular, the shape of the adsorption isotherm was unique compared with those of others. This greater adsorption may be attributed to adsorption at the inner surface, that is, the windows of sodalite allow the penetration of N2 into the pore structure. This was also suggested by the larger lattice constant.
