ABSTRACT:
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.
