Description

Herstellung von aktiven Sauerstoff enthaltenden Verbindungen Bei der katliodischen Herstellung aktiven Sauerstoff enthaltender Verbindungen treten zuweilen Korrosionen an den amalgamierten Kathoden auf.Preparation of active oxygen-containing compounds in the Catliodic production of compounds containing active oxygen sometimes occur Corrosion on the amalgamated cathodes.

Es hat sich gezeigt, daß dieser Gefahr durch häufige oder dauernde Benetzung mit frischem Quecksilber wirksam begegnet werden kann. Diese Benetzung kann z. B. geschehen durch Berieselung mit diesem Metall. Um die Oberfläche des von der Kathode abgelaufenen Quecksilbers in der Zelle vor dem Angriff der Flüssigkeit zu schützen, kann man es dauernd katholisch polarisieren. Das überschüssige Quecksilber fließt zweckmäßig durch einen siphonartigen Auslaß ab, der für den Elektrolyten durch Quecksilber abgesperrt ist. Statt der Berieselung mit metallischem Quecksilber kann man auch dem in den Kathodenraum eintretenden Elektrolyten kleine Mengen von Quecksilbersalzen zufügen. Da das Abscheidungspotential von Quecksilber wesentlich niedriger liegt als das Reduktionspotential von molekularem Sauerstoff, scheidet sich aus dem Salz das Metall vollständig und gleichmäßig an der Kathode ab, und zwar wegen des hohen Äquivalentgewichtes von Quecksilber ohne erheblichen Stromaufwand.It has been shown that this danger can be caused by frequent or permanent Wetting with fresh mercury can be effectively countered. This wetting can e.g. B. done by sprinkling with this metal. To the surface of the Mercury expired from the cathode in the cell prior to attack by the liquid to protect, one can constantly polarize it catholic. The excess mercury expediently flows off through a siphon-like outlet for the electrolyte blocked by mercury. Instead of being sprinkled with metallic mercury one can also the electrolyte entering the cathode compartment small amounts of Add mercury salts. Because the deposition potential of mercury is essential is lower than the reduction potential of molecular oxygen, separates The metal is completely and evenly removed from the salt at the cathode, and because of the high equivalent weight of mercury without considerable power consumption.
