T 5053 A B S T R A C T PROCESS FOR THE PREPARATION OF CRYSTALLINE (METALLO) SILICATES Process for the preparation of crystalline (metallo) silicates and/or derivatives thereof from a silica source, an organic cation source, a source of water and optionally an alkali earth) metal and/or an alumnium and/or a further metal source wherein a crystalline (metallo) silicate is produced under synthesis conditions from a solution or a gel wherein at least 30%, on atomic basis, of the silicon in said solution or gel originates from one or more crystalline ed quaternary ammonium or phosphonium double n-ring (metallo) silicate clathrates wherein n is 3, 4 or 5. Crystalline (metallo) silicates which can be suit- ably prepared according to the present process comprise SCS-1, SCS-2, SCS-4, dodecasil-3C, TMA-zeolite T, TMA-sodalite, ZSM-12, zeolite beta and zeolite L.
