摘要： A method for producing a fluorine-containing alkyl ether is disclosed wherein a sufficient reaction rate can be attained even under mild conditions. This method enables to efficiently perform post-processes such as distillation following the reaction. After introducing a polar non-protic solvent, a fluorine-containing ether, a catalyst, a fluorine-containing alkyl alcohol and a fluorinated olefin into a reaction vessel, the fluorine-containing alkyl alcohol and the fluorinated olefin are reacted with each other so as to produce a fluorine-containing alkyl ether. In this method for producing a fluorine-containing alkyl ether, the mass ratio between the polar non-protic solvent and the fluorine-containing ether introduced in the reaction vessel (polar non-protic solvent/fluorine-containing ether) is from 5/95 to 80/20.

摘要： A method for producing a fluorine-containing alkyl ether wherein a fluorine-containing alkyl alcohol and a fluorinated olefin are reacted in the presence of a solvent and a catalyst is characterized in that the fluorine-containing alkyl alcohol and the fluorinated olefin are continuously supplied into a reaction chamber, a reaction product including the fluorine-containing alkyl alcohol is continuously drawn out from the reaction chamber, and the reaction is conducted while keeping the concentration of the fluorine-containing alkyl alcohol in the reaction chamber at 7 mass% or less relative to the total organic component existent in the reaction chamber. With this method, a high-purity fluorine-containing alkyl ether can be produced at high reaction rate on an industrial scale.
