标 题:Process for the synthesis of IZM-2 zeolite in the presence of a template, 1,6-bis(methylpiperidinium)hexane dihydroxide
发明人：MARTINEZ FRANCO RAQUEL; BATS NICOLAS
权利人:IFP ENERGIES NOW
摘要: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.

摘要:The present invention relates to the synthesis of succinimides, in particular to a method for the synthesis of a succinimide compound, comprising the step of reacting an alkyne, with carbon monoxide and ammonia or an amine, in the presence of an iron catalyst, wherein the reaction is carried out in an amine liquid phase and/or in the absence of an ether solvent. The succinimides may be reduced to quaternary ammonium cations which may be used as structure directing agents in the synthesis of molecular sieves.

权利人:ALTEON INC
摘要:The present invention relates to a practical and facile synthesis of 2-(2-furoyl)-4(5)-(2-furanyl)-1H-imidazole (FFI) and analogs thereof. The synthesis utilizes a novel hydrazinium salt as an intermediate reaction product which facilitates the isolation of purified product in high yields.
