Abstract:
A process for synthesizing a porous crystalline material which comprises:(i) preparing a mixture capable of forming said material, said mixture comprising sources of water, an oxide of a tetravalent element Y, an oxide of a trivalent element X, wherein X is selected from the group consisting of aluminum, boron, gallium, iron, and indium, fluoride ions, and an organonitrogen cation RNm+capable of directing the synthesis of said material, wherein HF is the source of the fluoride ions and the molar ratio of said fluoride ions to said organonitrogen cations RNm+ in said mixture is greater than 1.15 m but less than 25 m; (ii) maintaining said mixture under crystallization conditions until crystals of said material are formed; and (iii) recovering said crystalline material from (ii).
