（産業上の利用分野）

。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a sodium carbonate/hydrogen peroxide adduct compound (hereinafter referred to as sodium percarbonate), which has been increasingly used as an oxygen generating agent due to its safety and stability. ) or a catalyst processed to generate oxygen from hydrogen peroxide.
（従来技術） 従来、これ等酸素発生剤に用いられる触媒は。(Conventional technology) Conventionally, the catalysts used for these oxygen generating agents are:

一定時間得られるなどは望むべくもなかった。Manganese dioxide, platinum, other metal salts such as iron and nickel are known, and if you graph the amount of oxygen generated per 4 minutes without using it as is, the curve will be parabolic with a peak in the first few minutes. There was no hope of being able to obtain a constant flow of oxygen for a certain period of time.

などの欠点かあった。(Problems to be Solved by the Invention) Subsequently, according to JP-A No. 57-160902, by coating the surface of the catalyst with arabic glue of different concentrations, the exposure time of the catalyst was changed, and a certain degree of control was achieved. Even if you look at the table 13 attached to the patent publication or try a supplementary test, when you graph the amount of oxygen generated per minute, the curve is not much different from a parabolic curve. At low temperatures (for example, below 15°C), even if a large amount of the adjusted catalyst is used, the flow rate generated is too low for practical use unless the solubility of Arabic glue at low temperatures is affected. I couldn't stand it. In addition to it,
The appearance of the reaction liquid increases due to the bubbles generated by the Arabic glue, and in order to prevent the reaction liquid from overflowing, it is unavoidable to make each reaction chamber larger, resulting in the overall size of the oxygen generator. Ta. In addition, since Arabic glue was used, there were drawbacks such as the need for a great deal of labor to clean up the product.
本発明は、それらの欠点を改良する為になされたちので
ある。The present invention has been made to improve these drawbacks.
（問題を解決するための手段）
ここて、その改良した点を列挙してみると、１、触媒の
表面を多孔質にする。(Means for solving the problem) Here, the improvements are listed as follows: 1. The surface of the catalyst is made porous.
２、粒径の異なる触媒を混在させる。2. Mix catalysts with different particle sizes.
３、触媒の多孔質な表面及び内部を水溶性の物質て埋め

It is inexpensive.'' 2. What does ``mix catalysts with different particle sizes'' mean?

状に加工する」とは。Catalysts with a small particle size naturally have a large specific surface area and fly up into the water together with oxygen gas, and are light and have a strong catalytic effect.On the other hand, if the particle size is large, they do not fly up in the water and are stable catalysts. The effect is obtained. Therefore, it is very useful to process catalysts with different particle sizes mixed together. What does J3 mean by ``Knead the porous surface and interior of the catalyst with a water-soluble substance so as to fill it, and process it into powder, granules, or solid form''?

マンガン（Ｍｎ０２）を使用する。"By filling the surface and interior of the catalyst with a water-soluble substance, the surface area of the added catalyst is reduced, thereby suppressing the rapid initial oxygen generation speed and slowing down the reaction. After that, as time passes, the oxygen The generation speed decreases (the solubility of sodium percarbonate decreases due to the increase in sodium carbonate, which is a reaction product), but on the other hand, when the catalyst is processed into powder, granules, or solids, As time passes, the water-soluble substance dissolves in the water from the surface of the catalyst to the inside, and the surface area of the catalyst increases, resulting in almost no change in the flow rate of oxygen generation.'' (Implementation) Example) l. Two types of catalysts with different particle sizes (the smaller one rAJ
