Abstract
A new synthetic porous crystalline material, designated ITQ-12, is disclosed having, in its calcined form, the X-ray diffraction pattern of Table 2 herein. Also disclosed are methods of making ITQ-12 in its silicate, aluminosilicate and borosilicate forms in the presence of HF using 1,3,5-trimethylimidazole as a directing agent and hydolyzed tetraethylorthosilicate as a silica source. ITQ-12 is useful in the conversion of methanol to olefins and as an adsorbent.
Claims11
A synthetic porous crystalline material comprising a framework of tetrahedral atoms bridged by oxygen atoms, the tetrahedral atom framework being defined by a unit cell with atomic coordinates in nanometers shown in Table 1, wherein each coordinate position may vary within ±0.05 nanometer.
A synthetic porous crystalline material characterized by an X-ray diffraction pattern including values substantially as set forth in Table 2 of the specification.
