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.
