Abstract:
A novel process is described for the preparation of a microporous crystalline solid, known as IZM-2 microporous solid or IZM-2 zeolite. This novel process consists of carrying out the synthesis of IZM-2 zeolite by conversion/transformation of a zeolite with structure type FAU in a fluorinated medium under hydrothermal conditions. In particular, said novel process consists of carrying out the synthesis of an IZM-2 zeolite in a fluorinated medium starting from a zeolite with structure type FAU used as the source of silicon and aluminium and a specific organic molecule or template comprising two quaternary ammonium functions, namely 1,6-bis(methylpiperidinium)hexane dihydroxide.

Claim (Index 1):
Process for the preparation of an IZM-2 zeolite, comprising at least the following steps:\n i) mixing, in an aqueous medium, at least one zeolite with structure type FAU having a molar ratio SiO 2 (FAU) /Al 2 O 3 (FAU)  of greater than or equal to 30, at least one additional source of an oxide XO 2  in a manner such that the molar ratio XO 2 /SiO 2 (FAU)  is in the range 0 to 4, at least one nitrogen-containing organic compound R, R being 1,6-bis(methylpiperidinium)hexane dihydroxide, and at least one source of at least one fluoride anion, the mixture having the following molar composition: (XO 2  + SiO 2 (FAU) )/Al 2 O 3 (FAU) in the range 30 to 600, H 2 O/(XO 2  + SiO 2 (FAU) ) in the range 1 to 100, R/(XO 2  + SiO 2 (FAU) ) in the range 0.01 to 0.6, BF/(XO 2  + SiO 2 (FAU) ) in the range 0.005 to 0.75, in which X is one or more tetravalent element(s) selected from the group formed by the following elements: silicon, germanium, and titanium, preferably silicon, SiO 2 (FAU)  being the quantity of SiO 2  supplied by the FAU zeolite, and Al 2 O 3 (FAU)  being the quantity of Al 2 O 3  supplied by the FAU zeolite, and in which BF is selected from fluorine salts in which B is a cation selected from the cations NH 4 + , Na + , K +  and Li + , and hydrofluoric acid in aqueous solution, ii) hydrothermal treatment of said mixture obtained from step i) at a temperature in the range 120\u00b0 C. to 200\u00b0 C. for a period in the range 1 day to 10 days, until said IZM-2 zeolite has been formed.
