Abstract
A polyfluoroalkyl alcohol, or a (meth)acrylic acid derivative thereof, represented by the following general formula:CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cOR(R:H or (meth)acrylic acid group; n: 1-6; a: 1-4; b: 1-3; and c: 1-3). Polyfluoroalkyl alcohol (R: hydrogen atom) can be produced by reaction of fluoroalkyl iodide represented by the following general formula:CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cIwith N-methyl formamide, followed by hydrolysis in the presence of an acid catalyst, whereas polyfluoroalkyl alcohol (meth)acrylic acid derivative (R: (meth)acrylic acid group) can be produced by reaction of the polyfluoroalkyl alcohol with (meth)acrylic acid.
