Abstract
PURPOSE:To obtain the titled compound useful as an intermediate for producing a perfluoro lower alkyl vinyl ether, a monomer for fluoropolymers, efficiently, by thermally decomposing a specific polyether compound in the presence of an active carbon catalyst at a specific temperature. CONSTITUTION:A polyether compound shown by formula I [Rf is perfluoro lower alkyl; X is CF2 or F; X' is CF2, F or H; Y is -COF, -COOH or -COOR (R is lower alkyl); n is 3-50] is thermally decomposed preferably by gas-phase reaction in the presence of granular active carbon catalyst having preferably about 20-200m<2>/g at about 180-400 deg.C, preferably 280-340 deg.C under normal pressure or normal pressure to give the aimed compound shown by formula II.
