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.

摘要:A method of producing 1,1,1,2,3,3-hexafluoropropane in a characteristic process in which tetrafluorochloropropene is first obtained from the dechlorofluorination (removing ClF) of 1,1,1,2,2-pentafluoro-3,3-dichloropropane and/or 1,1,2,2,3-pentafluoro-1,3-dichloropropane by hydrogen in the presence of a metal oxide catalyst and then the product olefin is fluorinated in the presence of a catalyst. By this method, 1,1,1,2,3,3-hexafluoropropane, which is useful as an action fluid and so on and has a property to help preserving the environment, and an intermediate in its synthesis can be easily produced at low cost.
