  • Patent number: 9868684
    Abstract: The invention pertains to a process for the manufacture of a perfluorovinylether by hydrodehalogenation of a halofluoroether (HFE) having general formula (I-A) or (I-B): RfO—CRf?X—CRf?Rf??X???(I-A) wherein Rf represents a C1-C6 perfluoro(oxy)alkyl group; Rf?, Rf? and Rf??, equal or different from each other, independently represent fluorine atoms or C1-C5 perfluoro(oxy)alkyl groups; X and X?, equal or different from each other, are independently chosen among Cl, Br or I; wherein Rf* and Rf*?, equal or different from each other, independently represent fluorine atoms or C1-C3 perfluoro(oxy)alkyl groups; Y1 and Y2, equal or different from each other, independently represent fluorine atoms or C1-C3 perfluoroalkyl groups; X and X? are as above defined; said process comprising contacting said halofluoroether (HFE) with hydrogen in the presence of a catalyst comprising palladium and at least one transition metal (M) selected from the group consisting of the metals of group VIIIB, other than palladium, and o
