Abstract:
1. A method of manufacturing a molecular sieve of the MCM-22 family, said method comprising the steps of: (a) providing a mixture comprising at least one source of ions of tetravalent element, at least one source of alkali metal hydroxide, at least one directing-agent (R), water, and at least one source of ions of trivalent element, said mixture having the following mole composition:  wherein Y is a tetravalent element, X is a trivalent element, M is an alkali metal; (b) treating said mixture at crystallization conditions for less than 72 hr to form a treated mixture comprising said molecular sieve, wherein said crystallization conditions comprise a temperature in the range of from about 160° C. to about 250° C.; and (c) recovering said molecular sieve.
