Hydrofluoroethers having at least one hydrogenated-OCFX'CH3 end group wherein X'=F, CF3 and their preparation process

摘要

Hydrofluoroethers of formula: T-CFX'-O-Rf-CFX-T' (II) wherein: T=CH3; X, X', equal to or different from each other, are selected between F, CF3; T00'=F, Cl, H, C1-C3 perfluoroalkyl, CH3, CH2OH, COCl, CHO, CO2H; Rf is a perfluoroalkylene or a perfluoropolyoxyalkylene and respective preparation process by reduction with hydrogen in the presence of a platinum catalyst supported on metal fluorides of the corresponding compounds with at least one -COCl end group.
