标 题:Process for the synthesis of IZM-2 zeolite in the presence of a template, 1,6-bis(methylpiperidinium)hexane dihydroxide

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:A method for synthesis of high quality colloidal nanoparticles using comprises a high heating rate process. Irradiation of single mode, high power, microwave is a particularly well suited technique to realize high quality semiconductor nanoparticles. The use of microwave radiation effectively automates the synthesis, and more importantly, permits the use of a continuous flow microwave reactor for commercial preparation of the high quality colloidal nanoparticles.

标 题 :ZSM-5 zeolite materials doped with fluorine species for the synthesis of MTBE and other acido-catalyzed reactions
发明人：MAO RAYMOND LE VAN
权利人:UNIV CONCORDIA
摘要:Provided herein is are acidic Z5M-5 zeollte materials which are highly active and selective in the synthesis of methyl tert-butyl ether (MTBE) and similar ethers. The materials are obtained by the preparation method comprising the main steps of: i) impregnation of zeolites with fluorine species using ammonium fluoride as precursor, preferably with a F loading of ca.1.9×10 3 mol.g −1 of zeolite; and ii) stepwise activation in air at preferably 250° C. and then preferably at 300° C. to 500° C., preferably 450° C. The method is preferably applied to desilicated ZSM-5 zeolite and provides conversion rates to MTBE superior to those obtained with prior art commercial AMBERLYSFâ„¢ resin (gas phase reaction at 70-80° C.) is obtained. No by-products, commonly produced by prior art commercial organic resin catalyst, are detected in the product spectrum.

标题:Homogeneous synthesis of cellulose ethers in ionic liquids

摘要:The invention is directed to a simple and new method for the homogeneous synthesis of cellulose ethers. Ionic liquids are not only used as solvent, but also as reaction media for the homogeneous etherification of cellulose. The dissolved cellulose is treated with the etherification agent in the absence of organic and/or inorganic bases and in the absence and/or in the presence of moderate amounts of water. The obtained cellulose ethers show new distributions of substitution on the polymer chain, resulting in new properties and applications.
