式のように反応して４８グラムの酸素が発生する。As an oxygen generation method utilized in such an oxygen generation device, a method of adding water to an addition compound of sodium carbonate and hydrogen peroxide in the presence of a catalyst can be considered. · wife! When water is added to the addition compound of 12 moles of sodium carbonate and hydrogen peroxide in the presence of a catalyst, the reaction occurs as shown in the following chemical formula, producing 48 grams of oxygen.

H20) 10H20+ 1.502↑In this reaction, when water is added to the addition compound of sodium carbonate and hydrogen peroxide, it decomposes into sodium carbonate and hydrogen peroxide. In this decomposition reaction, it is necessary to use a powdered catalyst in order to generate the amount of oxygen necessary to avoid emergency problems with a small amount of catalyst, but in that case, the decomposition reaction occurs rapidly. , and is accompanied by a large amount of heat generation. Therefore, the temperature of the reaction water rises instantaneously, reaching 100°C, causing a bumping state, and releasing oxygen and water vapor simultaneously, completing the reaction in an extremely short time.
そのために一定量でしかも一定時間継続して酸素を必要
とする急病や、災害時における酸素補給用として、この
方法を用いることは好ましくない。For this reason, it is not preferable to use this method for oxygen supplementation in the event of a sudden illness or disaster that requires a certain amount of oxygen for a certain period of time.

異なる加工をした触媒を加えることによって酸素を発生
せしめる方法である。To solve this problem, an oxygen generation method has been developed that uses a portable amount of an addition compound of sodium carbonate and hydrogen peroxide and a catalyst to constantly generate the amount of oxygen required for oxygen supply in an emergency over a predetermined period of time. It was done. It's carbonated) IJ
This is a method of generating oxygen by adding catalysts processed with different solubility to an aqueous solution of an adduct compound of aluminum and hydrogen peroxide.

起こる事はなく、溶解度の速い固形物から順次溶けて粉
末になる事により、次第に酸素を発生させ一定量の酸素
を一定時間供給できる。According to this method, since the catalyst is a solid substance, the reaction does not occur instantaneously; instead, the solid substance with the highest solubility gradually dissolves into powder, thereby gradually generating oxygen and supplying a certain amount of oxygen for a certain period of time. .

で反応が停止せず、途中で止めることができなかった。However, in this method, the amount of oxygen generated is small until the solid catalyst begins to dissolve and gradually increases, so the start-up speed is slow, which is a drawback. Furthermore, once the reaction started, the reaction did not stop until the addition compound of sodium carbonate and hydrogen peroxide was exhausted, and could not be stopped midway.
さらに溶けた触媒は回収できず捨ててしまわなければな

供することにある。The problem to be solved by the present invention is that oxygen can be freely generated and stopped using a relatively small amount of catalyst, the catalyst can be used repeatedly, and a sufficient amount of oxygen can be generated for oxygen supplementation in an emergency. The object of the present invention is to provide a method of generating oxygen that can be used to generate oxygen.

生方法である。In order to solve the above problems, the present invention generates oxygen by placing a porous granular catalyst in a metal mesh bag and placing it in an aqueous solution of an addition compound of sodium carbonate and hydrogen peroxide. This is a method of generating oxygen that stops the generation of oxygen by removing it.
次に本発明の酸素発生方法の実施例を述べる。 Next, an example of the oxygen generation method of the present invention will be described.

酸素が発生した。Porous granular manganese dioxide 52 was placed in a bag made of metal mesh and inserted into an aqueous solution in which an addition compound of sodium carbonate and hydrogen peroxide (No. 1002) was dissolved in water (No. 2001). As a result, 2.2 litges of oxygen was generated after 5 seconds.

発生する。Because the manganese dioxide catalyst is porous, the area in contact with the aqueous solution of the addition compound of sodium carbonate and hydrogen peroxide is relatively large, even though it is granular. When inserted into an aqueous solution, a reaction occurs immediately and oxygen is generated. Moreover, even with a relatively small amount of catalyst, enough oxygen is generated for emergency needs.
また、多孔質化した二酸化マンガンを入れた袋を水溶液
中から取出せば、直ちに反応が止み酸素の発生が停止す
る。この取出された触媒は再度使用し得る。Furthermore, if the bag containing the porous manganese dioxide is removed from the aqueous solution, the reaction immediately stops and the generation of oxygen stops. This removed catalyst can be used again.
