    Abstract: A method for purifying a treatment target solution which can remove a compound having an aliphatic hydrocarbon group which has at least one ionic group and a fluorine atom efficiently is provided.
    The method for purifying a treatment target solution of the present invention comprises bringing a treatment target solution containing a compound having an aliphatic hydrocarbon group which has at least one ionic group selected from the group consisting of a carboxylic acid group and a sulfonic acid group, and a fluorine atom and may contain an oxygen atom, at least one acid selected from the group consisting of HF and H2SO4 and water, into contact with a resin having a tertiary amino group to remove the compound having an aliphatic hydrocarbon group from the treatment target solution.

    Abstract: To provide a method for producing a perfluorinated compound, capable of easily producing a perfluorinated compound from which a high molecular weight polymer can be produced by a polymerization reaction, and a method for producing a fluorinated polymer using it.
    A method for producing a perfluorinated compound, which comprises step A of reacting a perfluoroalkoxide salt with a perfluoroallylating agent to obtain a crude product A containing a perfluoroallyl ether compound, or step B of subjecting a chlorofluorocarbon compound to dechlorination reaction to obtain a crude product B containing a perfluorinated α-olefin compound, to obtain a crude product X which is either the crude product A or the crude product B, and



    mixing the crude product X with a radical source to bring radicals generated by the radical source and the crude product X into contact with each other to obtain a crude product Y containing a perfluorinated compound which is either the perfluoroallyl ether compound or the perfluorinated α-olefin compound.
