ABSTRACT:
Perfluorinated ethers containing carboxylic acid fluoride groups and optionally units derived from hexafluoropropene epoxide or tetrafluoroethylene epoxide are reacted with fluorine at temperatures of from 50.degree. to 350.degree.C in the presence of metallic catalysts. During the reaction carbonyl difluoride is splitt off and an ether is obtained in high yield which is free of carboxylic acid fluoride groups. Metallic silver is well suited as catalyst.
