Abstract

Se produce un halógeno , como cloro, por electrólisis de una solución acuosa de un haluro de hidrógeno , como ácido clorhídrico, en una célula electrolítica con cámara anolítica y catolítica separadas por un electrolito polimérico sólido en forma de membrana cambiadora de ión hidratada, estable y selectivamente permeable. Los electrodo catalíticos en forma de óxidos reducidos de metales del grupo del platino, térmicamente estabilizados y ligados con fluorcarburos, están adheridos por lo menos a una superficie de la membrana y se pone en contacto con el ánodo adherido una solución acuosa de ácido clorhídrico para generar cloro en el ánodo e hidrógeno en el cátodo
