A method for the obtainment of an ester or a halide of a fluorinated sulfonic acid from an salt of a sulfonic acid is herein disclosed. The method is particularly useful for recovering waste sulfonate salts from reaction mixtures obtained by reaction of sulfonic esters of alcohols having a pKa lower than 15 with nucleophile compounds.
