Abstract:
1. A process for preparing an IZM-1 crystalline solid comprising mixing in an aqueous medium at least one source of at least one oxide XO 2 , optionally at least one source of at least one oxide Y 2 O 3 , optionally at least one source of at least one alkali and/or alkaline-earth metal with valency n, optionally at least one source of hydroxide ions and at least two different organic species R and S, hydrothermal treatment of said mixture until said IZM-1 crystalline solid forms, followed by filtration, washing, drying and calcining steps, wherein R is 6-(dibutylamino)-1,8-diazabicyclo[5.4.0]undec-7-ene and S is ethylene glycol, HO—CH 2 —CH 2 —OH, said IZM-1 crystalline solid having an X ray diffraction diagram including at least the peaks set out in the table below: in which: Vs=very strong; S=strong; M=medium; Mw=medium weak; W=weak; Vw=very weak, and having a chemical composition, expressed as the anhydrous base in terms of moles of oxides, defined by the following general formula: XO 2 : aY 2 O 3 ; bM 2/n O in which X represents at least one tetravalent element, Y represents at least one trivalent element and M is an alkali metal and/or an alkaline-earth metal with valency n, a and b respectively representing the number of moles of Y 2 O 3 and M 2/n O; a is in the range 0 to 0.02 and b is in the range 0 to 1.
