Abstract
The present invention discloses a method for producing a fluorine-containing alkyl (meth)acrylate represented by the following general formula (2): Rf—(CH2)k-[-A-(CH2)l—]m—OCOCR═CH2 (2) (wherein R is a hydrogen atom or a methyl group), characterized by reacting a fluorine-containing alcohol represented by the following general formula (1): Rf—(CH2)k-[-A-(CH2)l—]m—OH (1) (wherein Rf is a perfluoroalkyl group having 1 to 21 carbon atoms; A is S, SO or SO2; k is 0, 1 or 2; 1 is k, 2 or 3; m is 0 or 1; however, a case of k=0 and m=0 is excluded), (meth)acrylic acid, and a sulfonic acid halide in the presence of a base containing at least one kind of tertiary amine.
