A method for preparing molecular sieves and the molecular sieves obtained thereby are described. The method is selected from the group consisting of structure directing agents, at least one source of at least one oxide of tetravalent elements, and optionally oxides of trivalent elements, pentavalent elements and mixtures thereof. One or more sources of one or more oxides, optionally at least one source of elements selected from groups 1 and 2 of the periodic table, and optionally hydroxide ions Or preparing a reaction mixture comprising fluoride ions and holding the reaction mixture under conditions sufficient to form crystals of the molecular sieve. In the method, various imidazolium cations are used as structure directing agents. [Selection] Figure 1 |
