KAISERLICHESIMPERIAL
PATENTAMT,PATENT OFFICE,
Die Erfindung betrifft eine Verbesserung der bekannten, aus Chlorat oder Perchlorat und einem Metall, Metalloxyd oder -karbonat bestehenden, bei der Erhitzung Sauerstoff abgebenden Gemische. Es ist bekannt, daß der aus derartigen Gemischen gewonnene Sauerstoff stets eine kleine Menge Chlor enthält. Im günstigsten Falle fanden sich noch immer o,2 Prozent dem Sauerstoff beigemischt. DaThe invention relates to an improvement of the known, made of chlorate or perchlorate and a metal, metal oxide or metal carbonate, which emits oxygen when heated Mixtures. It is known that the oxygen obtained from such mixtures always contains a small amount of chlorine. In the best case, 0.2 percent was still mixed with the oxygen. There
ίο das Chlorgas durch seinen üblen Geruch lästig wird und auch die Metallteile der Apparate angreift, die der Verwendung des Sauerstoffs dienen, so hat man bereits vorgeschlagen, den gewonnenen Sauerstoff vor der Verwendung durch eine Chlor absorbierende Flüssigkeit, z. B. eine Lösung kaustischer Soda, streichen zu lassen.ίο the chlorine gas is annoying due to its bad smell and also attacks the metal parts of the apparatus that use the oxygen It has already been proposed to use the oxygen obtained before use by a chlorine absorbing liquid, e.g. B. a solution of caustic soda, delete allow.
Durch die vorliegende Erfindung wird ohne eine solche nachträgliche Behandlung ziemlich chlorfreier Sauerstoff gewonnen, indem man für die Entwicklung des Sauerstoffs ein Gemenge von solcher Zusammensetzung anwen-' det, daß so gut wie gar kein Chlor gas mehr entwickelt wird. Dieses Ziel wird erreicht, wenn als Metall ein solches in geringer Menge gewählt wird, dessen höchste Oxydationsstufe noch nicht den Charakter einer Säure hat und dessen Chlorid sich erst bei einer höheren Temperatur zersetzt, als bei der das Gemenge den Sauerstoff abgibt.The present invention becomes quite without such post treatment Chlorine-free oxygen obtained by creating a mixture for the development of the oxygen of such a composition that practically no more chlorine gas is used is being developed. This goal is achieved when the metal is a small amount is chosen whose highest oxidation level does not yet have the character of an acid and the chloride of which only decomposes at a higher temperature than that of the mixture gives off oxygen.
Wie diese Vorschrift bereits andeutet, beruht die Wirkung des beigemengten Metalls auf der Bildung eines hitzebeständigen Chlorids. Insoweit aber Metall überschüssig ist, wird es oxydiert. Dadurch ergibt sich eine kleine Verminderung der Ausbeute an Sauerstoff. Es ist deshalb vorzuziehen, das Metall als Oxyd, Hydrat oder Karbonat beizumengen. Selbstverständlich braucht der zur Chloridbildung dienende Zusatz nicht chemisch rein zu sein. So können im allgemeinen Mineralien, die das Metall oder eine seiner soeben angegebenen Verbindungen enthalten, unmittelbar verwendet werden, wenn ihre sonstige Zusammensetzung nicht den Bedingungen wider- 4S spricht, die schon bisher für die Nebenbestandteile des Gemenges galten.As this regulation already indicates, the effect of the added metal is based on the formation of a heat-resistant chloride. However, if there is excess metal, it is oxidized. This results in a small decrease in the yield of oxygen. It is therefore preferable to add the metal as an oxide, hydrate or carbonate. Of course, the additive used to form the chloride does not need to be chemically pure. Thus, in general, minerals, containing the metal or one of its just given compounds can be used directly if their other composition does not contradict the conditions 4 S speaks, the already previously considered for the minor components of the mixture.
Ein besonders wirksames Metall ist Barium. Von seinen Verbindungen (Bariumoxyd, Bariumsuperoxyd, Bariumhydrat, Bariumkarbonat) ist 5<> schon ι Teil auf 100 Teile Chlorat oder Perchlorat imstande, den Chlorgehalt des Sauerstoffs von 0,2 auf nur noch 0,01 Prozent herabzudrücken. A particularly effective metal is barium. Of its compounds (barium oxide, barium superoxide, Barium hydrate, barium carbonate) is 5 <> already ι part to 100 parts of chlorate or perchlorate able to reduce the chlorine content of oxygen from 0.2 to just 0.01 percent.
