A METHOD OF MAKING POROUS CRYSTALLINE MATERIALS

摘要

The present invention relates to new methods of making crystalline materials, as well as to new crystalline materials obtainable by such methods, and their use in hydrocarbon conversion processes. In one of its aspects, the invention relates to a method for preparing a crystalline molecular sieve. comprising oxides of one or more tetravalent element(s), optionally one or more trivalent element(s), and optionally one or more pentavalent element(s), said method comprising submitting to crystallization conditions one or more sources of said oxides in the presence of at least one organic templating agent R of formula C¹C²R¹R²N⁺ A^- (I), in which C¹ and C² each independently represent a substituted or unsubstituted cyclohexyl or cyclopentyl group; R¹ and R² each independently represent a methyl group, an ethyl group or a propyl group, or R¹ and R² 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.
