    摘要： Disclosed is a mixture of fluoroalkyl alcohols represented by the general formulae: CF 3 (CF 2 ) n (CH=CF) a (CF 2 CF 2 ) b (CH 2 CH 2 )OH [Ia] and CF 3 (CF 2 ) n-1 (CF=CH) a CF 2 (CF 2 CF 2 ) b (CH 2 CH 2) OH [Ib], wherein n is an integer of 1 to 5, a is an integer of 1 to 4, b is an integer of 0 to 3, and c is an integer of 1 to 3. This fluoroalkyl alcohol mixture is produced by the reaction of a fluoroalkyl iodide represented by the general formula: CF 3 CF 2 ) n (CH 2 CF 2 ) a (CF 2 CF 2 ) b (CH 2 CH 2 ) c I [II], with N-methylformamide, followed by hydrolysis in the presence of a basic compound.

    摘要： PROBLEM TO BE SOLVED: To provide an emulsifier, i.e., a compound comprising a ≤6C perfluoroalkyl group showing a low degree of bioaccumulation and having emulsification capability as good as ammonium pentadecafluorooctanoate of excellent emulsification capability. SOLUTION: The emulsifier includes a polyfluoroalkyl phosphonate represented by the formula: C n F 2n+1 (CH 2 CF 2 ) a (CF 2 CF 2 ) b (CH 2 CH 2 ) c P(O)(OM 1 )(OM 2 ), as its effective component (wherein M 1 represents a hydrogen atom, alkali metal, an ammonium salt group or an organic amine salt group; M 2 represents alkali metal, an ammonium salt group, or an organic amine salt group; n represents an integer of 1 to 6; a represents an integer of 1 to 4; b represents an integer of 1 to 3; and c represents an integer of 1 to 3). An aqueous solution or an organic solvent solution prepared from the emulsifier can effectively be used in emulsifying perfluoropolyether oil or a perfluorocarbon compound.
