Title:
METHOD FOR MANUFACTURING PERFLUOROVINYLETHERS
Document Type and Number:
WIPO Patent Application WO/2012/104365
Kind Code:
A2
Abstract:
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; 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.
