Abstract:
An MCM-22 family molecular sieve having an X-ray diffraction pattern of the as-synthesized MCM-22 family molecular sieve including d-spacing maxima at 12. 40. 25, 3. 570. 07 and 3. 420. 07 Angstroms and at least one peak between 26. 6 and 29 (2θ). The peak between 26. 6 to 29 (2θ) has a two theta (2θ) of about 26. 9. A method of manufacturing an MCM-22 family molecular sieve, said method comprising the steps of (a) combining at least one silicon source, at least one source of alkali metal hydroxide, at least one directing-agent (R), water, and optionally one aluminum source, to form a mixture having the following mole composition:.
