<p>Alkali metal chlorides are electrolysed as an amalgam or diaphragm and organic cpds. are added pref. chlorinated organics and/or surfactants esp. atylpyridine chloride or Deriphat 160(RTM) pref. 20-100 mg/l. Graphite anodes may be used. The improvement lowers the pH and surface tension and ultimately the O2 and Cl2 overpotential.</p> |
