Patent ID: 7635462

Claim:
A method of making a crystalline material iso-structural to ITQ-21, the method comprising: (a) providing a synthesis mixture comprising water, at least one source of germanium, at least one source of a tetravalent element X other than germanium, at least one structure directing agent R, optionally at least one source of trivalent element Y and optionally at least one source of fluoride, wherein the structure directing agent R is a compound of formula C 1 C 2 R 1 R 2 N + A − (I), in which C 1 and C 2 each independently represent a substituted or unsubstituted cyclohexyl or cyclopentyl group, R 1 and R 2 each independently represent a methyl group, an ethyl group or a propyl group, or R 1 and R 2 together with the nitrogen atom they are connected to form a ring containing 5 or 6 atoms, and A represents hydroxyl, fluorine, chlorine, bromine or iodine, (b) forming said crystalline material from the synthesis mixture; (c) recovering said crystalline material.
