Paragraph 0113, (2017/07/19)
PROBLEM TO BE SOLVED: To provide a sulfonic acid group-containing compound containing little metal, and a production method for efficiently obtaining the compound. SOLUTION: Provided is a sulfonic acid group-containing compound which is an aminoethanesulfonic acid having a metal content of 0 to 5.0 ppm, obtained by heating and reacting vinyl sulfonic acids, having a vinyl group and a sulfonic acid group, and an amino group-containing compound, having at least two reactive functional groups with one of which reactive functional groups being an amino group, in an aqueous solvent, and thereafter removing the solvent and the like. The functional group is a functional group which reacts with a group selected from: a hydroxyl group; a carboxyl group; an ester group; an amino group; a thiol group; an isocyanate group; an isothiocyanate group; a halogen atom; an acid anhydride group; and a conjugated group on a surface of fullerene, carbon nano-tube, graphene, or derivatives of these carbon compounds.
