Zusammenfassung:Process for the preparation of crystalline aluminum silicates. As aqueous mixture containing a compound of an alkali metal (M), a quaternary alkylammonium compound (R4NX), a silicon compound and an aluminum compound, the various compounds being present in the following molar ratios expressed in moles of the oxides: M2O : SiO2 = 0.01 - 0.35, (R4N)2O : SiO2 = 0.07 - 0.15, H2O : SiO2 = 8 - 12, and Al2O3 : SiO2 < 0.1, is maintained at elevated temperature until the crystalline silicate has been formed. The silicate is separated from the mother liquor and calcined. After calcination during 1 hour in air at 500 DEG C, the X-ray powder diffraction pattern shows as the strongest ones the following four lines: Process for the production of an aromatic hydrocarbon mixture using this silicate as catalyst.
