Abstract:
A process for synthesizing the crystalline material MCM-58 which comprises the steps of:(i) preparing a mixture capable of forming said material, said mixture comprising sources of alkali or alkaline earth metal (M), an oxide of trivalent element (X), an oxide of tetravalent element (Y), hydroxyl (OHâˆ’) ions, water and a 1-(1-adamantyl)pyridinium directing agent (R), wherein said mixture has a composition, in terms of mole ratios, within the following ranges: YO2/X2O3=10-1000 H2O/YO2=5-100 OHâˆ’/YO2=0.05-1 M/YO2=0.05-1 R/YO2=0.01-0.4 (ii) maintaining said mixture under sufficient conditions until crystals of said material are formed; and (iii) recovering said crystalline material from step (ii).
