A mixture of fluoroalkyl iodides of the formula C 2 F 5 (CF 2 CF 2 ) n I (“n” is an integer of ≧0) wherein the sum of such fluoroalkyl iodides of n=3 and n=4 contained is ≧85 mol % is provided. This mixture is subjected to an ethylene addition step and an esterification step, and C 2 F 5 (CF 2 CF 2 ) n CH═CH 2 and C 2 F 5 (CF 2 CF 2 ) n CH 2 CH 2 OH are removed. Thus, there can be obtained a mixture of fluorine-containing (meth)acrylic esters of the formula C 2 F 5 (CF 2 CF 2 ) n CH 2 CH 2 OCOCR 1 ═CH 2 (wherein R 1 represents a hydrogen atom or a methyl group, and “n” is an integer of ≧0) wherein the content of impurities (namely, olefins of the formula C 2 F 5 (CF 2 CF 2 ) n CH═CH 2 and alcohols of the formula C 2 F 5 (CF 2 CF 2 ) n CH 2 CH 2 OH) is low. |
