In a first sulfation step, 2-perfluoroalkylethyl iodide is brought into contact with fuming sulfuric acid to obtain a reaction mixture comprising 2-perfluoroalkylethyl sulfate and bis(2-perfluoroalkylethyl)sulfate. Then, in a first hydrolysis step, 2-perfluoroalkylethyl sulfate produced in the first sulfation step is hydrolyzed to obtain a reaction mixture comprising 2-perfluoroalkylethyl alcohol. In a second sulfation step, bis(2-perfluoroalkylethyl)sulfate produced in the first sulfation step is brought into contact with fuming sulfuric acid to obtain a reaction mixture comprising 2-perfluoroalkylethyl sulfate. Then, in a second hydrolysis step, 2-perfluoroalkylethyl sulfate produced in the second sulfation step is hydrolyzed to obtain a reaction mixture comprising 2-perfluoroalkylethyl alcohol. According to such procedures, 2-perfluoroalkylethyl alcohol can be obtained in a high yield.
