Preparation method of perfluorohexylethyl sulfonate

The present invention relates to the technical field of fluorocarbon surfactants, and discloses a preparation method of perfluorohexylethyl sulfonate. The preparation method comprises: S1, dissolving sodium hydrosulfide in absolute ethyl alcohol, adding perfluorohexylethyl iodide and a catalyst, and carrying out a reaction under a heating condition to obtain perfluorohexyl ethanethiol; S2, blending perfluorohexyl ethanethiol and nitric acid, and reacting under a heating condition to obtain perfluorohexylethyl sulfonic acid; and S3, reacting the perfluorohexylethyl sulfonic acid with an alkali, purifying, and drying to obtain the perfluorohexylethyl sulfonate. According to the preparation method, perfluorohexylethyl iodide is used as a raw material, and absolute ethyl alcohol is used as a solvent. The method can reduce the production cost, digest production waste, and is safe, environment-friendly and simple to operate.
