N. published an article.Reference of Pyridine-3-sulfonic acid The title of the article was Hybrid ion-exchange membranes based on heteroaromatic sulfonic acid derivatives. And the article contained the following:
Membranes exhibiting proton conductivity have been prepared by sol-gel synthesis using tetraethoxysilane and heteroaromatic sulfonic acid derivatives (2-phenyl-5-benzimidazolesulfonic acid and 3-pyridinesulfonic acid) in the presence of phosphoric acid and polyvinyl butyral. The membranes are gels composed of a polyvinyl butyral polymer matrix with uniformly distributed particles of silica containing mols. of heteroaromatic sulfonic acid derivatives mech. incorporated in its network structure. The membranes synthesized from 2-phenyl-5-benzimidazolesulfonic acid or 3-pyridinesulfonic acid exhibit a conductivity of 0.1X10-2 or 0.55X10-2 S/cm at 353 K, an ion-exchange capacity of 2.70 or 1.84 mequiv/g, and a proton-transfer activation energy of 24.93 or 21.73 kJ/mol, resp.; at a relative water content of 50%, the tensile strength is 4 or 6 MPa and the elastic modulus is 128 or 191 MPa, resp. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Reference of Pyridine-3-sulfonic acid
