hydrofluorether with at least a hydrogenated (- ch3 ocfx ') - endgruppe (x = f, cf3). methods for their manufacture

摘要

Hydrofluoroethers of formula: T-CFX'-O-Rf-CFX-T' 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.
