Reaction Steps

As a method for the synthesis of a sulfonated polyaniline, there are known, for example, a method for the synthesis of a sulfonated polyaniline by electrochemically polymerizing aniline and m-aminobenzenesulfonic acid (Journal of The Chemical Society of Japan, 1985, 1124 and JA-A-2-166,165), a method for the synthesis of a sulfonated polyaniline by electrochemically polymerizing an o-, m- or p-aminobenzenesulfonic acid alone [Lecture Preprint II in the 64th Autumn Annual Convention of The Chemical Society of Japan, 706 (1992)], a method for the synthesis of a sulfonated polyaniline by chemically polymerizing aniline and an o- or m-aminobenzenesulfonic acid (JP-A-1-301,714), a method for the chemical oxidation polymerization of an aminobenzenesulfonic acid compound or monomers comprising an aminobenzenesulfonic acid compound and an aniline compound (JP-A-6-56,987), a method for the sulfonation with conc. sulfuric acid of an emeraldine type polymer (polyaniline) obtained by chemical or electrochemical polymerization (JP-A-58-210,902), a method for the sulfonation with sulfuric anhydride/triethyl phosphate complex (JP-A-61-197,633), a method for the sulfonation with fuming sulfuric acid [J. Am. Chem. Soc., (1991) 113, 2665-2671, J. Am. Chem. Soc., (1990) 112, 2800 and WO91-06887], a method for the synthesis of a sulfonated polyaniline of the N-substitution type by chemically polymerizing diphenylamine-4-sulfonic acid (sodium salt) [Polymer, (1993) 34, 158-162] and the like.
