    • The invention pertains to a process for the manufacture of a perfluorovinylether by hydrodehalogenation of a halofluoroether (HFE) having general formula (l-A) or (l-B): RfO-CRf'X-CRf"Rf"'X' (l-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 CI, Br or I; formula (I-B) 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 of group IB.
    • 本发明涉及通过具有通式(1A)或(1B)的卤代氟醚(HFE)的加氢脱卤制备全氟乙烯基醚的方法:RfO-CRf'X-CRf“Rf”'X'(1A)其中Rf代表 C1-C6全氟(氧)烷基; Rf',Rf“和Rf”“彼此相同或不同,独立地表示氟原子或C1-C5全氟(氧)烷基; X和X'彼此相同或不同,独立地选自CI,Br或I; 式(I-B)其中Rf *和Rf *'彼此相同或不同,独立地表示氟原子或C1-C3全氟(氧)烷基; Y1和Y2彼此相同或不同,独立地表示氟原子或C1-C3全氟烷基; X和X'如上所定义; 所述方法包括在催化剂存在下使所述卤代氟醚(HFE)与氢气接触,所述催化剂包含钯和至少一种选自除钯以外的第VIIIB族金属和IB族的过渡金属(M)。
