CATALYST OF TRIS(BIS(PERFLUOROALKYLSULFONYL))IMIDE-RARE EARTH ELEMENT SALT

摘要

PROBLEM TO BE SOLVED: To perform extremely high activity in a conversion reaction by producing a catalyst to be used for a conversion reaction of organic compounds by an acid catalyst from a specified tris[bis(perfluoroalkylsulfonyl)imide]-rare earth element salt. ;SOLUTION: This catalyst efficient as Friedel-Crafts reaction catalyst is produced from a tris[bis(perfluoroalkylsulfonyl)imide]-rare earth element salt having a formula: [(RfSO₂)₂N]₃M (wherein Rf stands for perfluoroalkyl group, M for scandium, yttirum, ytterbium). This tris[bis(perfluoroalkylsulfonyl)imide]- rare earth metal salt is produced by synthesizing tris[bis(perfluoroalkylsulfonyl) imide]-alkali metal salt by a reaction of perfluoroalkylsulfonyl fluoride and an alkali metal-bis(trimethylsilyl)amide and then treating the alkali metal salt with concentrated sulfuric acid.;COPYRIGHT: (C)1998,JPO
