Disclosed is a process for the preparation of fluorohalogenated ethers by reaction of a fluorinated fluorooxycompound with a halogenated olefin. During the reaction which is carried out at low temperature in liquid phase in the presence of an inert solvent the, fluoro-oxycompound is continuously fed in the form of a solution in an inert solvent. The fluorohalogenated ethers that are so obtained in a continuous manner form fluorooxy-compounds having more than two carbon atoms, can be halogenated to produce the corresponding perfluorovinyl-ethers.
