Description

Haltbarmachung von Wasserstoffsuperoxyd Durch das Patent 560 124 ist ein Verfahren zur Haltbarmachung von Wasserstoffsuperoxyd oder anderen aktiven Sauerstoffenthaltenden Lösungen geschützt. Das Verfahren besteht darin, daß kleine Mengen von Verbindungen mit ätherartig gebundenem Sauerstoff cLen Lösungen zugefügt werden.Preservation of hydrogen peroxide Patent 560 124 protects a process for preservation of hydrogen peroxide or other active oxygen-containing solutions. The method consists in that small amounts of compounds with ether-like bound oxygen are added to solutions.

Es wurde gefunden, daß man dieses Verfahren auch auf feste Verbindungen des Wasserstoffsuperoxyds ausdehnen kann, indem man diesen kleine Mengen organischer Stoffe zumischt, welche eine Ätherbindung enthalten. Solche Stoffe sind beispielsweise die Doppelverbindungen des Wasserstoffsuperoxyds mit Harnstoffen (Patentschriften 293 125 und 294 725) und ähnlichen Stoffen. Es gelingt hierdurch, den Zerfall der Verbindungen so zu verlangsamen, daß diese auch in feuchter Luft bei erhöhter Temperatur längere Zeit unzersetzt bleiben.It has been found that this process can also be applied to solid joints of hydrogen peroxide can expand by adding these small amounts of organic Mixes substances that contain an ether bond. Such substances are for example the double compounds of hydrogen peroxide with ureas (patents 293 125 and 294 725) and similar substances. It succeeds in the disintegration of the Slow down compounds so that they work in moist air at elevated temperatures remain undecomposed for a long time.

Durch die so erreichte Stabilisierung wird der Anwendungsbereich des Wasserstoffsuperoxyds in Form seiner festen Verbindungen wesentlich erweitert.The stabilization achieved in this way increases the scope of the Hydrogen peroxide in the form of its solid compounds is considerably expanded.

Bei der Konservierung der festen Verbindungen dies Wasserstoffsuperoxyds können wasserlösliche und was-terunlösliche Konservierungsmittel verwendet werden.In the preservation of the solid connections, this is hydrogen peroxide Both water-soluble and water-insoluble preservatives can be used.

Beispiel Zu einer Verbindung aus Wasserstoffsuperoxyd und Harnstoff werden je i % eines der folgender- Äther durch Vermahlen zugemischt: Phenylglycerinäther, o-Methoxyphenylglycerinäther, Benzylexäthyläther.Example of a compound of hydrogen peroxide and urea each i% of one of the following ethers is added by grinding: phenylglycerin ether, o-Methoxyphenylglycerinäther, Benzyläthyläther.

Mischungen von Wasserstoffsup,eroxydcarbamid mit i % Konservierungsmittel, die einen Anfangsgehalt von 3.5 % H202 hatten, wurden in lose verschlossenen Flaschen in einem mit Wasserdampf gesättigten Raum bei einer Temperatur von 4o° aufbewahrt.Mixtures of hydrogen soup, oxydcarbamide with 1% preservative, which had an initial content of 3.5% H202, were in loosely closed bottles stored in a room saturated with water vapor at a temperature of 40 °.
