A mixture of fluoroalkyl alcohols represented by C 2 F 5 (CF 2 CF 2 ) n CH 2 CH 2 OH (n is an integer of 0 or more), wherein n = 3 and n = 4 fluoroalkyl alcohols A mixture containing 85 mol% or more in total is prepared, reacted with an acrylic acid compound, and then unreacted C 2 F 5 (CF 2 CF 2 ) n CH 2 CH 2 OH is removed to remove impurities ( that, C 2 F 5 (CF 2 CF 2) n CH = CH -olefins and C 2 F 5 represented by 2 (CF 2 CF 2) n CH 2 CH fluorine content is low in the alcohol) of represented by 2 OH A mixture of acrylic esters is obtained. |
