Verfahren zur Darstellung von Sauerstoff
Vorliegende Erfindung bezweckt die Darstellung von Sauerstoff aus sauerstoffreichen Körpern, welche, wie besonders die Alkalichlorate und Perchlorate unter Einwirkung hoher Temperatur unter vollständiger oder teilweiser Entwicklung ihres Sauerstofigehaltes zerfallen.
Um derartige sauerstoffreiche Körper in bequemer Weise für die Erzeugung von Sauerstoff nutzbar zu machen, werden dieselben gemäss vorliegender Erfindung in Verbindung mit einem Reaktiousgemenge benutzt, welches bei Erhitzung au einem Punkt oder bei der Einwirkung von Wasser sich unter starker Wärmeentwicklung umsetzt, so dass der sauerstoffreiche Körper dadurch zur Freigabe seines Sauerstoffes veranlasst wird. Als Reaktionsgemenge zur Erzeugung

Process for the preparation of oxygen
The present invention aims to produce oxygen from oxygen-rich bodies which, like especially the alkali chlorates and perchlorates, decompose under the action of high temperature with complete or partial development of their oxygen content.
In order to make such oxygen-rich bodies usable in a convenient manner for the production of oxygen, they are used according to the present invention in connection with a reactive mixture which, when heated to one point or when exposed to water, is converted with strong heat development, so that the oxygen-rich This causes the body to release its oxygen. As a reaction mixture for generation
EMI1.1
the alkali and alkaline earth metals used.
This reaction mixture offers a special advantage for the purpose of producing oxygen from oxygen-rich bodies. that the salts of supersulfuric acid react with the oxides or superoxides of the alkali and alkaline earth metals, releasing oxygen, so that at the same time as generating the reaction temperature necessary for the decomposition of the chlorates etc. the advantage of increased oxygen evolution is achieved. In known mixtures of perchlorates and super oxides, the super oxides only act to lower the melting temperature of the mixture,
EMI1.2
The reaction between persulfate, superoxide or oxide or hydrate is important,
An example of the chemical process is the use of Nahum persulfate. and calcium oxide accepted.
The reaction that takes place can be printed out as follows:

and in the case of using a superoxide, e.g. B. that of sodium:

For the practical exercise of the process, the mixture to be used can expediently be stored in suitable containers (cartridges). which you to the eye

Look the oxygen generation is initiated by heating at one point, for example, by a burning match or an ignition pin or by the action of water.
