    wherein R f is a fluoroalkyl ether end group having 5 to 50 carbon atoms, R 1 is an aliphatic alkyl end group or an aliphatic alkenyl end group, R 2 is an aliphatic alkylene group or an aliphatic polyalkylene oxide group which have no or one or more carbon atoms, each of R 3 and R 4 is an aliphatic alkylene group having no or one or more carbon atoms, X is a connecting group selected from the group consisting of
    (wherein R 5 is an aliphatic alkylene group having no or one or more carbon atoms, and R 6 is a hydrogen atom or an aliphatic alkyl group having 1 to 12 carbon atoms), each of W and Y is connecting group selected from the group consisting of
    (wherein R 7 is a hydrogen atom or a methyl group), Z is a connecting group selected from the group consisting of
    and each of 1, m and n is zero or 1. There are disclosed a fluorine-containing compound of a specific structure which has in the molecule a fluoroalkyl ether end group, an aliphatic hydrocarbon end group and a carboxyl end group, and has a molecular weight of hundreds to about 3,000; and a process for producing the fluorine-containing compound. This fluorine-containing compound can be utilized in magnetic recording media in the form of a lubricant composition.

    摘要： Polyfluoroalkyl compounds:

            (R-X-)₂-Q-Y

    wherein
       R represents CF₃(CF₂) n - (n: an integer of 7 to 13),
       X represents a hydrocarbyl linking group containing 6 to 11 carbon atoms and optionally containing a double bond, triple bond or ether bond at any position,
       Q represents a connector between the hydrophobic group of R-X- and the hydrophilic group of Y, and
       Y represents a hydrophilic group.
    The compounds may be produced by subjecting R-X-OH and L-glutamic acid to azeotropic dehydration reaction in the presence of a salt-forming agent of AH (wherein A represents, for example, a p-toluenesulfonate ion or a sulfate ion), subsequently an acylation reaction and a quaternizing reaction. The compounds may be used for forming a thin film by, for example, the Langmuir-Brodgett process. The film may be supported on a porous support to produce a membrane capable of separating substances.
