A process for synthetizing mordenites having a high catalytic activity, in which the SiO2:Al2O3 molar ratio ranges from 16 to 40, said process comprising the step of mixing an organic base with H2O and with at least a Na compound, an Al compound, and a Si compound, wherein said base is a diethyl-piperidinium compound and wherein the crystallization temperature of mordenite and the SP factor are selected within area A B C D of FIG. 1, the crystallization time being longer than two days. |
