Methods using compressed oxygen are known, but all of these have storage problems. Methods using chemical reactions are also known, including methods using perchlorates, superoxides, and peroxides. These methods have advantages such as being easy to use and relatively easy to store. Of these chemical reactions, those using perchlorate are called chlorate candles and have been known for a long time, but the temperature of the generated oxygen is high and the products of the chemical reaction contain C42 etc. It has drawbacks such as containing poisonous gas. Also, products that use superoxide require water vapor, and products that use the water vapor in exhaled breath are known, but they have the disadvantage that they do not generate oxygen immediately, and are generally made with a small built-in chlorate candle. be.

触媒の存在下で水を加えた時におこる次の反応を利用し

' H20) + H20+1.502 In this reaction, when water is added to the addition compound of carbonate and hydrogen peroxide, it dissociates into sodium carbonate and hydrogen peroxide, and this hydrogen peroxide is decomposed into water and oxygen by a catalyst. . This decomposition reaction occurs extremely rapidly and is accompanied by heat generation. Therefore, depending on the amount of catalyst and water used, the temperature can reach 100"C instantaneously.
Bumping occurs, releasing oxygen and water vapor at the same time, and the reaction ends in an extremely short time. Therefore, it is not preferable for supplying oxygen in the event of a disaster or sudden illness, which requires oxygen supply in a fixed amount and for a fixed period of time.

水と触媒を加える量をコントロールしなければならない
。しかし緊急時に上述のようなコントロールをしながら
酸素の補給を得ることは実際上不可能である。Therefore, in order to constantly generate the oxygen necessary for breathing in an emergency for a predetermined period of time with a portable amount of an addition compound of soda carbonate and hydrogen peroxide that can be used in an emergency and is portable, it is necessary to suppress the sudden generation of oxygen and produce a constant amount of oxygen. It is necessary to control it so that it occurs. To do this, water and a catalyst were gradually added in small amounts to the addition compound of carbonate and hydrogen peroxide, while observing the amount of oxygen generated.
The amount of water and catalyst added must be controlled. However, in an emergency, it is practically impossible to obtain supplemental oxygen while controlling as described above.

A method is known in which oxygen is generated by causing the above-mentioned reaction. By solidifying the catalyst with Arabic glue of different concentrations, a solid substance with different dissolution rates is created, and by adding water to a mixture of this solid substance and an addition compound of carbonic acid and hydrogen peroxide, oxygen is lengthened in fixed amounts. This is a method of generating oxygen that can be generated over a period of time.

ある。This conventional oxygen generation method using an addition compound of soda carbonate and hydrogen peroxide can stably generate a certain amount of oxygen for a certain period of time, but it is not possible to adjust and change the amount of oxygen generated. Furthermore, it is not possible to stop the generation of oxygen at an appropriate point in time. Furthermore, once used, the aqueous solution of the addition compound of sodium carbonate and hydrogen peroxide and the catalyst cannot be used again. Furthermore, depending on the conditions, it may be necessary to wait 1 to 2 minutes before the required amount of generation is obtained after generation starts, and this is an unavoidable problem when using solid catalysts, so it is not suitable for emergency use. It's inappropriate.

It is an object of the present invention to provide a method for generating oxygen gas.

発生させる酸素の量をコントロール出来る。The present invention is an oxygen gas generation method in which oxygen is generated by adding an addition compound of soda carbonate and hydrogen peroxide or an aqueous solution thereof to an aqueous solution containing colloidal platinum in water. When colloidal platinum is added to an aqueous solution of an addition compound of hydrogen oxide, the catalyst (colloidal platinum) added to the hydrogen peroxide solution comes into contact with it and immediately reacts, generating oxygen. Furthermore, the amount of oxygen generated changes depending on the amount of colloidal platinum added, so the amount of oxygen generated can be controlled by changing the amount of colloidal platinum added.

In other words, as shown in Fig. 1, colloidal platinum 1 is encapsulated in a gelatin capsule 2, and when used, the gelatin 2 is thinned (2a) is broken and the colloidal platinum 1 is extruded from the capsule 2. If the amount of colloidal platinum 1 sealed in the capsule 2 is set to an appropriate value according to the amount of oxygen generated, a certain amount of oxygen can be produced per unit time by dropping one capsule. It is possible to generate .If necessary, by dropping colloidal platinum in two or more capsules, the amount generated per unit time can be doubled, tripled, etc.

プセルの保管が面倒である欠点がある。If the capsule material is made water-soluble, it is possible to generate oxygen by adding it into the water, which is an addition compound of soda carbonate and hydrogen peroxide, but it is troublesome to store the capsules. There are drawbacks.

4 is obtained by blowing an arc between platinum wires 15 and 16 while cooling with a 15-16 wire.Next, as another method of the present invention, sodium carbonate and hydrogen peroxide are added to an aqueous solution of colloidal platinum dissolved in water. Oxygen can be immediately generated by adding a compound powder or an aqueous solution thereof.
