Abstract:
1. A method for preparing a MWW-type molecular sieve, comprising: (a) preparing a reaction mixture containing: (1) at least one source of at least one oxide of a tetravalent element; (2) optionally, one or more sources of one or more oxides selected from the group consisting of oxides of trivalent elements, pentavalent elements, and mixtures thereof; (3) at least one source of an element selected from Groups 1 and 2 of the Periodic Table; (4) hydroxide ions; (5) cationic 1,3-diisobutylimidazolium as a structure directing agent; and (6) water; and (b) subjecting the reaction mixture to crystallization conditions sufficient to form crystals of the MWW-type molecular sieve.
