Abstract
A new synthetic porous crystalline material, designated ITQ-13, is disclosed having, in its calcined form, the X-ray diffraction pattern of Table 2 above. Also disclosed are methods of making ITQ-13 in its silicate and borosilicate forms in the presence of HF using hexamethonium dihydroxide as a directing agent and hydolyzed tetraethylorthosilicate as a silica source. Aluminum-containing ITQ-13 can be produced by Al exchange of the borosilicate material. ITQ-13 is useful as an acid catalyst and as an adsorbent.
Claims12
A synthetic porous crystalline material having a 3-dimensional channel system comprising a first set of generally parallel channels each of which is defined by a 10-membered ring of tetrahedrally coordinated atoms, a second set of generally parallel channels which are also defined by 10-membered rings of tetrahedrally coordinated atoms and which intersect with the channels of the first set, and a third set of generally parallel channels which intersect with the channels of said first and second sets and each of which is defined by a 9-membered ring of tetrahedrally coordinated atoms.
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.
