Description

Verfahren zur Herstellung katalysatorhaltiger Alkalisuperoxyde. Zusatz zum Patent 32o8xo. Gemäß Patent 320810 werden zur Lufterneuerung verwendbare katalysatorhaltige Alkalisuperoxyde dadurch gewonnen, daß das in bekannter Weise erhaltene wasserhaltige Superoxyd von geeigneter Korngröße mit dem feingepulverten festen Katalysator eingestäubt wird. Es würde nun gefunden, daß das Verfahren vereinfacht und ein haltbares Erzeugnis erhalten wird durch Verwendung von Lösungen von Stoffen, welche durch Wechselwirkung mit dem Superoxyd den Katalysator bilden.Process for the preparation of catalyst-containing alkali peroxides. additive for patent 32o8xo. According to patent 320810, catalyst-containing air can be used for air renewal Alkali peroxides obtained by the fact that the hydrous obtained in a known manner Superoxide of suitable grain size dusted with the finely powdered solid catalyst will. It has now been found that the process is simplified and a durable product is obtained by using solutions of substances which by interaction form the catalyst with the superoxide.

Nach dem neuen Verfahren wird zunächst das Superoxyd in bekannter Weise aus dem Alkalimetall ohne Zusatz eines Katalysators hergestellt und gemahlen. Dann werden die Körner von gewünschter Größe ausgesiebt und jetzt erst nur diesen verwendbaren Körnern der Katalysator durch ein- oder mehrmaliges Aufsprühen der Lösung einer geeigneten Verbindung, z. B. Mangansulfat, hinzugesetzt. Das Superoxyd wird dabei fortgesetzt durch Rührvorrichtungen bewegt und gleichzeitig gekühlt. Der Zusatz der Lösung muß so langsam verlaufen, daß Erhitzungen über x5° vermieden werden. Sämtliche Körner überziehen sich dabei mit einer dünnen, gleichmäßigen braunen Schicht von Mangansuperoxyd. Ein Abstäuben des Katalysators findet nicht statt.According to the new process, the superoxide is first known Made from the alkali metal without the addition of a catalyst and ground. Then the grains of the desired size are sifted out and only this now usable grains of the catalyst by spraying on one or more times Solution of a suitable compound, e.g. B. Manganese sulfate added. The superoxide is continued to be moved by stirring devices and cooled at the same time. The addition of the solution must proceed so slowly that heating over x5 ° is avoided will. All the grains are covered with a thin, even brown Layer of manganese superoxide. The catalyst is not dusted off.
