A method for producing a fluoroalkyl ether, which comprises reacting a
fluoroalkyl alcohol with a fluorinated olefin in the presence of a
solvent and a catalyst, wherein the fluoroalkyl alcohol and the
fluorinated olefin are continuously supplied into a reactor, a reaction
product containing the fluoroalkyl ether is continuously withdrawn from
the reactor, and the reaction is carried out while the concentration of
the fluoroalkyl alcohol present in the reactor is maintained to be at
most 7 mass % based on the total organic component present in the
reactor. According to the present invention, a fluoroalkyl ether having a
high purity can be produced in an industrial scale and at a high reaction
rate.
