Description
この発明は、高純度の次亜塩素酸水溶液を容易に生成するためのパウダーに関する。 The present invention relates to a powder for easily producing a high-purity aqueous solution of hypochlorous acid.
従来より、次亜塩素酸水が利用されているが、この次亜塩素酸水を生成するための専用のパウダーは現在のところ見当たらない。 Conventionally, hypochlorite water has been used, but no special powder for producing this hypochlorite water has been found at present.
次亜塩素酸水は殺菌力を有することが以前より知られており、各方面で多用されている。
通常は原液を希釈して用いるが、しかし液体として１０リットルや２０リットル単位での販売となるために、その運搬費用がかさむとともに、保管スペースの問題があった。
本発明は以上に鑑み、液体ではなく粉粒体として製造し、これを水に溶かして用いることにて、上記課題を解決し得る、新規かつ有用なる手段を提供することを目的として発明されたものである。Hypochlorite water has long been known to have bactericidal activity and is widely used in various fields.
Normally, the undiluted solution is diluted and used, but since it is sold in units of 10 liters or 20 liters as a liquid, the transportation cost is high and there is a problem of storage space.
In view of the above, the present invention has been invented for the purpose of providing a novel and useful means capable of solving the above-mentioned problems by producing a powder or granular material instead of a liquid and dissolving it in water for use. It is a thing.
課題を解決する手段として本発明は以下の構成とした。すなわち、
粉粒体状のジクロロイソシアヌル酸ナトリウムに粉粒体状のｐＨ調整剤を混和する。
本発明は以上の構成よりなる高純度次亜塩素酸水溶液生成用パウダーである。The present invention has the following configuration as a means for solving the problem. That is,
The powdery sodium dichloroisocyanurate is mixed with the powdery pH adjuster.
The present invention is a powder for producing a high-purity hypochlorous acid aqueous solution having the above constitution.
本発明によれば、粉粒体状のジクロロイソシアヌル酸ナトリウムと同じく粉粒体状のｐＨ調整剤を混和したものであり、次亜塩素酸水自体利用方式の場合に比べて少ない分量で用いるので、その運搬並びに保管が容易である。また、その劣化も極小である。 According to the present invention, the powdery sodium dichloroisocyanurate is mixed with the powdery pH adjuster, and it is used in a smaller amount than in the case of the hypochlorite water itself utilization method. , It is easy to transport and store. Moreover, the deterioration is also minimal.
以下、本発明の実施形態について説明するが、まず次亜塩素酸水について説明する。
一般に食材の除菌には古くから次亜塩素酸ナトリウムが用いられ、器具や手指の除菌にはアルコールが使われてきた。除菌力は水中の塩素濃度が関係しており、ｐＨ値により変化する。図１にて示すように、図中の曲線が塩素濃度を示しており、次亜塩素酸ナトリウム水では２０パーセント以下となっている。次亜塩素酸水ではこれが８０〜１００パーセントであり、高い除菌力が得られる。しかし、安定性に問題があり、塩化水素を放出しながら徐々に分解する性質を有している。Hereinafter, embodiments of the present invention will be described, but first, hypochlorite water will be described.
In general, sodium hypochlorite has been used for sterilizing foodstuffs for a long time, and alcohol has been used for sterilizing instruments and fingers. The sterilizing power is related to the chlorine concentration in water and changes depending on the pH value. As shown in FIG. 1, the curve in the figure shows the chlorine concentration, which is 20% or less in the sodium hypochlorite water. In hypochlorite water, this is 80 to 100%, and high sterilizing power can be obtained. However, there is a problem with stability, and it has the property of gradually decomposing while releasing hydrogen chloride.
次亜塩素酸（ＨＯＣＬ）がタンパク質の有機物と接触すると、酸化反応と塩素化反応が起こり、これらの反応にて微生物のタンパク質を酸化や塩素化することにて微生物を死滅させる。図中のＯＣＬ−イオンも除菌力を有するが、微弱であって、大腸菌群により除菌テストでは次亜塩素酸の８０倍の時間が必要であった。
次亜塩素酸水はほとんどの細菌やウイルスに除菌効果を有し、有効塩素濃度５０ｐｐｍで一分以内で除菌できる。また、次亜塩素酸水は高温で除菌力の増加が認められており、４０度では２０度の約６倍の効果が生まれる。When hypochlorous acid (HOCL) comes into contact with an organic substance of a protein, an oxidation reaction and a chlorination reaction occur, and these reactions oxidize and chlorinate the protein of the microorganism to kill the microorganism. The OCL- ion in the figure also has sterilizing power, but it is weak, and it took 80 times longer than hypochlorous acid in the sterilization test due to coliform bacteria.
Hypochlorite water has a sterilizing effect on most bacteria and viruses, and can be sterilized within 1 minute at an effective chlorine concentration of 50 ppm. In addition, hypochlorite water has been found to increase its sterilizing power at high temperatures, and at 40 degrees it is about 6 times more effective than 20 degrees.
この次亜塩素酸水の生成手段はいくつかがある。
１．次亜塩素酸ナトリウムを水で希釈する。（２００〜６００ｐｐｍ）
これは、図にて示すように、有効塩素量のうち、次亜塩素酸存在比率は１０〜２０パーセントしか含まれていない。
２．食塩の電気分解
食塩水をイオン交換膜を用いて電気分解し、陽極側に発生する塩素ガスが水に溶けて次亜塩素酸水が生成される。
３．希塩酸の電気分解
陽極反応で発生する塩素ガスが水に溶けて次亜塩素酸水が生成される。
４．次亜塩素酸ナトリウムをｐＨ調整
希釈した次亜塩素酸ナトリウムのｐＨを調整して次亜塩素酸水溶液を得る。
５．ジクロロイソシアヌル酸ナトリウムを水に溶かすThere are several means of producing this hypochlorite water.
1. 1. Dilute sodium hypochlorite with water. (200-600ppm)
As shown in the figure, this contains only 10 to 20% of the amount of effective chlorine in which hypochlorous acid is present.
2. 2. Electrolysis of saline solution The saline solution is electrolyzed using an ion exchange membrane, and the chlorine gas generated on the anode side dissolves in water to generate hypochlorite water.
3. 3. Electrolysis of dilute hydrochloric acid Chlorine gas generated by the anodic reaction dissolves in water to generate hypochlorite water.
4. Adjusting the pH of sodium hypochlorite Adjust the pH of diluted sodium hypochlorite to obtain an aqueous solution of hypochlorous acid.
5. Dissolve sodium dichloroisocyanurate in water
本発明は次亜塩素酸水の生成に、ジクロロイソシアヌル酸ナトリウムとｐＨ調整剤を用いる手法である。
ジクロロイソシアヌル酸ナトリウムは白色粉体で水によく溶ける性質があり、水に溶かすことにて次亜塩素酸水が生成される。
ジクロロイソシアヌル酸ナトリウムはイソシアヌル酸ナトリウムという有機物を塩素化した粉状の化合物で、水に溶けると除菌力の強い次亜塩素酸水となる。また、顆粒の状態で２〜３年間は安定した塩素濃度の維持ができる。図で示したように、水溶液のｐＨ値により、有効塩素量のうち、次亜塩素酸存在比率が異なるために、ｐＨ調整が必要である。
ｐＨ調整剤不使用ではｐＨ値が７．５〜８程度となり、有効な除菌力が得られない。
鋭意探索の結果、このｐＨ調整剤としてのリンゴ酸を見いだし、適切な配合比にて、除菌力の最適条件を発見することができた。リンゴ酸は、果実のリンゴに多く含まれていることから、この名で呼ばれるようになったが、本発明で使用するのは白色微粉末状のものである。The present invention is a method using sodium dichloroisocyanurate and a pH adjuster for the production of hypochlorite water.
Sodium dichloroisocyanurate is a white powder and has the property of being well soluble in water, and when dissolved in water, hypochlorite water is produced.
Sodium dichloroisocyanurate is a powdery compound called sodium isocyanuricate, which is a chlorinated organic substance. When dissolved in water, it becomes hypochlorite water with strong sterilizing power. In addition, a stable chlorine concentration can be maintained for 2 to 3 years in the state of granules. As shown in the figure, it is necessary to adjust the pH because the abundance ratio of hypochlorous acid in the effective chlorine amount differs depending on the pH value of the aqueous solution.
When the pH adjuster is not used, the pH value becomes about 7.5 to 8, and effective sterilizing power cannot be obtained.
As a result of diligent search, we found malic acid as this pH adjuster, and found the optimum conditions for sterilizing power with an appropriate compounding ratio. Malic acid has come to be called by this name because it is abundant in fruit apples, but the one used in the present invention is a white fine powder.
次ぎに、本発明製造のための混和（混合）例について説明する。
１．異径の有底筒状容器を２個用意し、一方を上部容器他方を下部容器として、下部容器 に対し上部容器をかぶせることができる。
２．下部容器に粉粒状のジクロロイソシアヌル酸ナトリウムを１キログラム投入して均等 にならし、その上にＤＬリンゴ酸を２５０グラム均等平均的に投入する。
３．縦に穴筋の入った専用へらで４〜５回全体を混ぜ合わす。
４．上記容器を機械方式で回転させながら、容器内の外側から内側に円周に沿って中央に 混合された粉山を作る。
５．回転を止め、上部容器を下部容器にかぶせて天地逆とする。
上記３から５の作業を２回以上反復する。
以上にて、均一混合体が完成する。Next, an example of mixing (mixing) for producing the present invention will be described.
1. 1. Two bottomed tubular containers with different diameters can be prepared, one as the upper container and the other as the lower container, and the lower container can be covered with the upper container.
2. 2. Add 1 kg of powdered granular sodium dichloroisocyanurate to the lower container and evenly add 250 grams of DL malic acid to it evenly and evenly.
3. 3. Mix the whole 4 to 5 times with a special spatula with vertical holes.
4. While rotating the container mechanically, a powder pile mixed in the center along the circumference is formed from the outside to the inside of the container.
5. Stop the rotation and cover the upper container with the lower container to turn it upside down.
Repeat
With the above, the uniform mixture is completed.
使用のジクロロイソシアヌル酸ナトリウムは、比較的粒子が粗く形成されており、リンゴ酸は結晶もしくは結晶性微粉末であるために、混合に工夫が必要で、一般的攪拌では不均等となりやすい。そのために既述の混和手段としたのである。
ジクロロイソシアヌル酸ナトリウムの粒子サイズを１０とすればリンゴ酸の粒子サイズは約１〜２程度である。ジクロロイソシアヌル酸ナトリウムの表面には無数の凹凸があり、この凹凸にリンゴ酸粒子がからんで均一混合となる。また、ジクロロイソシアヌル酸ナトリウム同士が接触すると隙間ができるが、この隙間にもリンゴ酸粒子が入り込むこととなるのである。The sodium dichloroisocyanurate used has relatively coarse particles, and malic acid is a crystal or crystalline fine powder. Therefore, it is necessary to devise a mixing method, and it tends to be uneven by general stirring. Therefore, the miscibility method described above was used.
Assuming that the particle size of sodium dichloroisocyanurate is 10, the particle size of malic acid is about 1 to 2. The surface of sodium dichloroisocyanurate has innumerable irregularities, and malic acid particles are entangled in these irregularities to form a uniform mixture. In addition, when sodium dichloroisocyanurates come into contact with each other, a gap is formed, and malic acid particles also enter the gap.
以上、本発明について記したが、本発明はジクロロイソシアヌル酸ナトリウムのｐＨ調整剤としてのリンゴ酸を付加することで、次亜塩素酸水溶液のｐＨ度を変化させ、除菌効果の最も高いｐＨ値を製造するところにその特徴を有するものである。
また、粉流体を水に溶かして用いるので、その運搬や保管が容易となる。
なお、ｐＨ調整剤としては、既述のリンゴ酸以外に、クエン酸も利用可能であるが、その配合比には注意が必要である。
本発明は１リットルの水道水に約０．３グラムを入れ、十分に攪拌することで、約１００ｐｐｍの濃度の次亜塩素酸水（ｐＨ６程度）を得ることができる。
以上のごとく、本発明によって高除菌力を発揮できる高純度次亜塩素酸水溶液生成用のパウダーを得ることができる。As described above, the present invention has been described. In the present invention, by adding malic acid as a pH adjuster for sodium dichloroisocyanurate, the pH degree of the aqueous hypochlorous acid solution is changed, and the pH value having the highest sterilizing effect is obtained. It has its characteristics in the place where it is manufactured.
Moreover, since the powder fluid is used by dissolving it in water, it is easy to transport and store it.
As the pH adjuster, citric acid can be used in addition to the above-mentioned malic acid, but it is necessary to pay attention to the compounding ratio thereof.
In the present invention, about 0.3 g of tap water is put into 1 liter of tap water and sufficiently stirred to obtain hypochlorite water (pH about 6) having a concentration of about 100 ppm.
As described above, according to the present invention, it is possible to obtain a powder for producing a high-purity hypochlorous acid aqueous solution capable of exhibiting high sterilizing power.
