    Abstract: There is provided a method for preparing crystalline ultra-large pore oxide materials. The materials are formed from reaction mixtures comprising an amphiphilic compound, such as a cetyltrimethylammonium compound, a source of at least one oxide, such as silica, and water. The concentration of amphiphilic compounds in these reaction mixtures is rather low. The addition of an inorganic salt, such as sodium bromide, to the reaction mixture may result in the increased thermal stability of the as-synthesized form of the crystalline material and may also alter the crystalline phase of the product.

    Abstract: A method of preparing silicoaluminophosphate (SAPO) compositions from a forming mixture which comprises sources of oxides of silicon, aluminum and phosphorus wherein the oxides of silicon and phosphorus are provided at least in part by a reagent containing both phosphorus and silicon reactive sites in the same molecule; and maintaining the forming mixture under conditions sufficient to form said compositions. The reagent is preferably a phosphonate-functionalized organosiliconate such as diethylphosphatoethyltriethoxysilane.
