    • A process of preparing a crystalline porous solid selected from silicas and metallosilicates, such as, aluminosilicate zeolites or clathrasils. The process involves preparing a reaction mixture containing ammonia; water in a controlled concentration; a (hydrocarbyl)ammonium polysilicate hydrate salt; a mineralizer, such as ammonium fluoride; optionally, a source of a metal oxide, such as aluminum nitride; and optionally, a source of a charge-balancing cation or a structure directing agent; and maintaining the mixture at a temperature and for a time so as to produce the crystalline porous solid. A novel silica which is isostructural with zeolite P1 is prepared. Also prepared are a novel silica which is isostructural with zeolite beta and a novel TMA sodalite having a silica/alumina molar ratio between 12 and about 20.
    • 制备选自二氧化硅和金属硅酸盐如硅铝酸盐沸石或盐酸盐的结晶多孔固体的方法。 该方法包括制备含有氨的反应混合物; 受控浓度的水; (烃基)聚硅酸铵水合物盐; 矿化剂,如氟化铵; 可选地,金属氧化物源如氮化铝; 和任选的电荷平衡阳离子源或结构导向剂; 并将混合物保持在一段温度和一段时间以产生结晶多孔固体。 制备与沸石P1同构的新型二氧化硅。 还制备了与沸石β同构结构的新型二氧化硅和具有12至约20的二氧化硅/氧化铝摩尔比的新型TMA方钠石。
