Abstract: PURPOSE: A preparation method of gallosilicate molecular sieve with a gismondine structure in K2O-Ga2O3-SiO2-H2O system is provided to control the molar ratio of structure components freely by substituting Ga and K for Al and Na of zeolite, respectively. The gallosilicate molecular sieve is applicable to catalysts, adsorbents and ion exchangers. CONSTITUTION: The gallosilicate molecular sieve is prepared by the following steps: mixing H2O, KOH, and a source of Ga such as gallium oxide or Ga2O3xH2O for 2-4hrs.; heating it for 12-24hrs. and cooling to room temperature; adding a source of Si such as colloid silica, sodium silicate and fumed silica, and stirring for 4-24hrs., resulting in a gel represented as vK2O : 1.0Ga2O3 : wSiO2 : zH2O (v=6.0-8.0, w=5.0-15.0, z=50-250); heating at 80-130deg.C for 1-10days; washing with H2O and drying.
