    摘要： There is provided a method for preparing a pillared layered material, designated MCM-36, with a characteristic X-ray diffraction pattern. Upon calcination of the swollen, non-pillared form of this material, the layers collapse and condense upon one another in a somewhat disordered fashion to form a non-swellable material. However, when the swollen layered material is intercalated with polymeric oxide pillars, the layer separation is maintained, even after calcination. A quaternary ammonium silicate, such as tetramethylammonium silicate, is used as a pillaring agent for treating the swollen material.

    摘要： 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.
