<p>A synthetic porous crystalline material MCM-35 has an X-ray diffraction pattern including the lines (I). It has a composition comprising the molar relationship X2O3:(n)YO2 wherein n is at least 30, X is a trivalent element and Y is a tetravalent element. It is prepared from a reaction mixture containing sources of alkali metal cations (M), a trivalent element (X) oxide, a tetravalent element (Y) oxide, hexamethyleneimine (R) and water, said trivalent element being selected from aluminum, boron, iron and gallium, said tetravalent element being selected from silicon and germanium, and having a composition in terms of mole ratios within the following ranges: YO2/X2O3 = 30 to 200, H2O/YO2 = 10 to 100, OH-/YO2 = 0.01 to 0.2, M/YO2 = 0.01 to 1.0, R/YO2 = 0.1 to 1.0 by maintaining it under sufficient crystallization conditions until crystals of said material are formed.</p> |
