    • To provide a process for producing a fluorinated alkyl ether, whereby a sufficient reaction rate can be attained even under mild reaction conditions, and a post-process such as distillation after the reaction can be efficiently carried out. A process for producing a fluorinated alkyl ether, which comprises introducing an aprotic polar solvent, a fluorinated ether, a catalyst, a fluorinated alkyl alcohol and a fluorinated olefin into a reactor, and then, reacting the fluorinated alkyl alcohol with the fluorinated olefin, characterized in that the ratio of the two components of the aprotic polar solvent and the fluorinated ether introduced into the reactor is the aprotic polar solvent/the fluorinated ether=5/95 to 80/20 by mass ratio.

    • 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olefin are continuously supplied into a reactor, a reaction product containing the fluoroalkyl ether is continuously withdrawn from the reactor, and the reaction is carried out while the concentration of the fluoroalkyl alcohol present in the reactor is maintained to be at most 7 mass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.
    • 一种制备氟烷基醚的方法,其包括在溶剂和催化剂存在下使氟代烷基醇与氟化烯烃反应,其中将氟代烷基醇和氟化烯烃连续地供入反应器中,将含有氟代烷基醚 从反应器中连续取出,反应进行,同时反应器中存在的氟代烷基醇的浓度维持在反应器中存在的总有机成分的7质量%以下。 根据本发明,可以以工业规模和高反应速度制备高纯度的氟烷基醚。
