Method for producing perfluoropolyether containing halogen different from fluorine and having an acid terminal group |
| abstract |
(57) [Summary] (Problem corrected) [Problem] To have a functional acid group such as an acyl halide or a carboxyl group or a derivative thereof (acid or ester) at one end and a halogen different from fluorine at another end. The present invention relates to a method for producing a perfluoropolyether, which has a perfluoroalkyl group contained therein. In the presence of perhalogenated ethylene containing at least one halogen atom different from fluorine, C 3 F 6 and / or C 2 F 4 are converted from −20 ° C. to − The liquid reaction mixture is photo-oxidized under UV irradiation using oxygen gas at a temperature of 100 ° C., followed by heat treatment of the peroxide groups at 180 ° -220 ° C., or by photo irradiation with UV irradiation. A method for producing a perfluoropolyether, comprising removing by treatment. |
