KAISERLICHESIMPERIAL
PATENTAMT.^PATENT OFFICE. ^
Die salpetersauren Alkalien sind zur Herstellung von Alkalisuperoxyd bis jetzt noch nicht benutzt worden, weil es noch nicht gelang, Schmelzgefäfse herzustellen, welche der Einwirkung der Hitze und des gebildeten Alkalioxyds widerstehen. Zwar kann man die Zersetzung durch Zumischung von Kupferblech, Braunstein und anderen Metalloxyden fördern, jedoch ist das entstandene Alkalioxyd infolge seiner Mischung mit Metalloxyden (Ozonide) nicht zu dem technisch wichtigen Superoxyd oxydirbar.The nitric acid alkalis are still used in the production of alkali peroxide until now has not been used because it has not yet been possible to manufacture melting vessels which the Resist exposure to heat and the alkali oxide formed. Although you can see the decomposition promote by adding copper sheet, brownstone and other metal oxides, but the resulting alkali oxide is a result its mixture with metal oxides (ozonides) does not result in the technically important superoxide oxidizable.
Angestellte Versuche zeigten noch, dafs die Oxyde der Erdalkalien und des Magnesiums den Zweck erreichen lassen, indem sie die Zersetzung der Alkalinitrate befördern und die Oxydation zu Superoxyd nicht hindern. Sie bilden ein Aufnahmemedium für den geschmolzenen Salpeter und das daraus entstehende feuerflüssige Alkalioxyd, geben der zersetzten Masse eine poröse, zur Oxydation geeignete Beschaffenheit und erlauben die Superoxydbildung durch Behandlung mit gereinigter Luft.Experiments carried out showed that the oxides of alkaline earths and magnesium let achieve the purpose by promoting the decomposition of the alkali nitrates and the Do not prevent oxidation to superoxide. They form a recording medium for the melted Saltpetre and the resulting molten alkali oxide give the decomposed mass a porous, oxidizing surface suitable consistency and allow superoxide formation by treatment with purified Air.
Die Alkalinitrate werden mit den hier technisch in Betracht kommenden Oxyden, Kalk oder Magnesia gemicht, indem man auf 100 Th. Salpeter etwa 70 bis 90 Th. Magnesia bezvv. Kalk nimmt. In feuerfesten Gefäfsen steigender Hitze ausgesetzt, beginnt die Masse bei Dunkelrothglut nitrose Gase zu entwickeln, die schliefslich bei Rothglut allmälig durch Sauerstoff und Stickstoff verdrängt werden. Bei heller Rothglut ist die Zersetzung vollendet. Die erhaltene graue, poröse Masse wird bei einer zwischen 300 und 5000 C. liegenden Temperatur mit trockener und kohlensä'urefreier Luft behandelt, wobei das Alkalioxyd in Superoxyd übergeht. Trägt man nun die gepulverte Masse unter Rühren in kaltes Wasser ein, so erhält man nach Entfernung des unlöslichen Kalks oder der Magnesia eine Superoxydlösung, die direct zum Bleichen verwendet werden kann. Läfst man die Superoxydlösung mit dem Kalk- oder Magnesianiederschlage unter beständigem Rühren zusammen, so setzt sie sich mit dem Kalk vollständig und mit der Magnesia unvollständig zu Alkalihydrat und Calcium- bezw. Magnesiumsuperoxyd um. Es kann jedoch auch die klare Superoxydlösung mit löslichen Calcium-, Strontium- oder Bariumsalzen oder deren Hydraten versetzt werden, wodurch die Erdalkalisuperoxydhydrate unlöslich ausfallen.The alkali nitrates are mixed with the oxides, lime or magnesia which are technically possible here, by adding about 70 to 90 th. Magnesia to 100 th. Saltpeter. Lime takes. When exposed to increasing heat in refractory vessels, the mass begins to develop nitrous gases when it is red-hot, which is gradually displaced by oxygen and nitrogen when it is red-hot. When the glow is bright red, the decomposition is complete. The gray, porous mass obtained is treated at a temperature between 300 and 500 0 C. temperature with dry air and kohlensä'urefreier, wherein the alkali oxide turns into peroxide. If the powdered mass is then introduced into cold water with stirring, a superoxide solution is obtained after the insoluble lime or magnesia has been removed, which can be used directly for bleaching. If the superoxide solution is allowed to combine with the lime or magnesia precipitate with constant stirring, it is completely combined with the lime and incompletely with the magnesia to form alkali hydrate and calcium or calcium. Magnesium superoxide around. However, soluble calcium, strontium or barium salts or their hydrates can also be added to the clear superoxide solution, as a result of which the alkaline earth superoxide hydrates are insoluble.
