    摘要: A method for producing a compound represented by formula (P1): (B 1f ) mp (A 1 ) np ,
    wherein
    B 1f is RfCOO,
    Rf is a hydrocarbon having one or more fluorine atoms,
    A 1 is a group excluding H,
    mp is (valence of A 1 ) x np and is 1 or 2,
    np is mp/(valence of A 1 ) and is 1,
    A 1 has a valence of 1 or 2,

    the method comprising step A of reacting
    a compound represented by formula (S1): (B 1f ) (R 1 ),
    wherein
    B 1f is as defined above, and
    R 1 is an organic group,
    and

    a compound represented by formula (S2) : (A 1 ) ms2 (B 2 ) ns2 ,
    wherein
    A 1 is as defined above,
    B 2 is OH, CO 3 , or HCO 3 ,
    ms2 is (valence of B 2 ) x ns2/ (valence of A 1 ) and is 1 or 2, and
    ns2 is (valence of A 1 ) x ms2/ (valence of B 2 ) and 1 or 2,
    or a hydrate thereof.


    Such a method is a novel production method of a fluorinated carboxylic acid salt compound (preferably a fluorinated carboxylic acid salt compound having a low water content).
