ABSTRACT:
A method for synthesizing MCM-48 includes combining an inorganic silica reagent, an alkylammonium hydroxide and halide-containing surfactant to form a reaction mixture which is maintained under sufficient conditions to form a crystalline MCM-48 product. In a preferred embodiment, the organic silica reagent and the alkylammonium hydroxide are combined in the agueous medium to form a first reactions mixture and the halide-containing surfactant is then added to the first mixture so as to form a second reaction mixture which is then reacted to form the MCM-48 product. The crystalline MCM-48 material according to the invention can be functionalized by adding aluminum. The crystalline MCM-48 product produced by the process of this invention possesses an X-ray diffraction pattern indicative of a cubic unit cell with Ia3d symmetry.
