非水溶媒中でのゼオライト合成の試み

The synthesis of zeolites in non-aqueous solvent such as methanol. xylene and 2-propanol was carried out with various procedures. Using tetraethoxysilane, aluminum triisopropoxide and sodium hydroxide, the crystals developed sufficiently were not formed in these solvents. But the crystals were developed by addition of trace amounts of water. In 2-propanol, the excellent crystal was formed with fumed silica for the first time. Silica sodalite was prepared according to D. M. Bibby et al. 's method. The several properties of these crystals were surveyed.
