            A-Pf-Z ···     (2)

            Z-Pf-Z ···     ((3)

    wherein
    Pf represents a divalent perfluoropolyether group,
    A each independently represents an R 1 - group, an R 1 -O-group, an R 2 O-CH 2 -R 3 - group, or an R 2 O-CH 2 -R 3 -O- group,
    R 1 each independently represents an alkyl group,
    R 2 each independently represents an alkyl group,
    R 3 each independently represents a divalent organic group containing 1 to 4 carbon atoms,
    Z each independently represents an -R 5 -CH 2 OH group or an -O-R 5 -CH 2 OH group, and
    R 5 each independently represents a bond or a divalent organic group containing 1 to 4 carbon atoms,
    the method comprising:
    adsorbing the mixture onto a stationary phase, and
    eluting the perfluoro(poly)ether group-containing monoalcohol compound represented by formula (2) by one mobile phase selected from the group consisting of hydrofluorocarbons, hydrochlorofluorocarbons, hydrofluoroethers, fluorine-containing ester solvents, and fluorine-containing aromatic solvents to separate the perfluoro(poly)ether group-containing monoalcohol compound represented by formula (2) from the perfluoro(poly)ether group-containing monoalcohol compound represented by formula (3).

    摘要： An object of the present invention is to provide a method for producing a compound having an oxydifluoromethylene skeleton at a high yield by a simple process without using highly toxic starting materials, such as dibromodifluoromethane, while generating almost no difficult-to-separate impurities. A reaction between a thionocarboxylic acid ester (which may be obtained by a reaction between a halogenated thiocarbonyl compound and a specific compound as required) and a compound represented by Formula: XF n (wherein X represents chlorine, bromine, or iodine, and n represents a natural number of 1 to 5) gives a compound having an oxydifluoromethylene skeleton at a high yield. Various groups, such as an aromatic ring group, may also be introduced in high yield by reacting this compound with a boronic acid compound and the like as required.

    摘要： A problem of the present invention is to provide a method of isolating perfluoro(poly)ether group-containing carboxylic acid compounds. The method of the present invention is a method of isolating, from a mixture comprising a perfluoro(poly)ether group-containing compound; and a perfluoro(poly)ether group-containing monocarboxylic acid compound or a perfluoro(poly)ether group-containing dicarboxylic acid compound, the above carboxylic acid compounds. The method comprises the steps of mixing the mixture, a fluorine atom-containing nonpolar solvent, and a polar stationary phase with each other, isolating the perfluoro(poly)ether group-containing compound from the polar stationary phase using a nonpolar mobile phase, and isolating the carboxylic acid compound from the polar stationary phase using the polar mobile phase. The nonpolar mobile phase comprises a fluorine atom-containing nonpolar solvent, and the polar mobile phase comprises a fluorine atom-containing polar solvent, comprises a combination of a fluorine atom-containing nonpolar solvent and a fluorine atom-containing polar solvent, or comprises a combination of a fluorine atom-containing nonpolar solvent and a fluorine atom-non-containing polar solvent.
