【発明の属する技術分野】
本発明は、ヨウ素系非水溶性固体防菌剤または殺菌剤の製造方法に関する。
【０００２】
【従来の技術】
ヨウ素系非水溶性固体防菌剤または殺菌剤は、飲料用水、水泳プール用水、風呂および温泉などの浴用水、あるいは空気中に浮遊する微生物の防菌剤または殺菌剤として重要な物質である。
【０００３】
従来、ヨウ素系非水溶性固体防菌剤または殺菌剤としては、特開昭５１−８８６２５号公報に記載されたシクロデキストリン、特開昭５４−７４８８５号公報に記載されたキトサン、特開昭５９−１９３１８９号公報に記載されたプラスチックビーズ、特開昭６０−２１８３１２号公報に記載された陰イオン交換樹脂、特開昭６０−２２４６０７号公報に記載された活性炭、および、特開平１０−２４５４０３号公報に記載された多孔質無機化合物などを担体として用いて、ヨウ素を担持せしめた組成物が知られている。
【０００４】
また、ヨウ素系非水溶性固体防菌剤または殺菌剤の製造方法としては、ヨウ素およびヨウ化カリを含む溶液と、非水溶性担体とを接触せしめる方法が知られている。
【０００５】
【発明が解決しようとする課題】
従来のヨウ素系非水溶性固体防菌剤または殺菌剤の製造方法は、高価なヨウ素およびヨウ化カリウムを使用することから、製造コストの削減が容易ではなく経済的ではないという問題を有している。
【０００６】
本発明の目的は、効率的かつ経済的に安価なヨウ素系非水溶性固体防菌剤または殺菌剤の製造方法を提供することである。
【０００７】
【課題を解決するための手段】
本発明は、ブローイングアウト法で得られるヨウ素吸収液へ酸化剤を添加してヨウ素およびヨウ素イオンを含有させた含有液を調製し、このヨウ素およびヨウ素イオンを含有させた含有液を非水溶性担体に接触させるものである。
【０００８】
【発明の実施の形態】
以下、本発明のヨウ素系非水溶性固体防菌剤または殺菌剤の製造方法の一実施の形態を説明する。
【０００９】
ヨウ素イオンを溶解する水溶液へ塩素系の酸化剤を投入し、ヨウ素イオンを遊離のヨウ素とした後、空気で追い出し、亜硫酸水素ナトリウムなどの還元性溶液に吸収させる方法であるブローイングアウト法により得られるヨウ素吸収液を原料とする。
【００１０】
このブローイングアウト法により得られるヨウ素吸収液へ酸化剤を添加してヨウ素およびヨウ素イオンを含有させた含有液を調製した後、非水溶性担体と接触せしめる。
【００１１】
ブローイングアウト法で得られるヨウ素吸収液へ添加する酸化剤の種類は、通常、塩素、次亜塩素酸ナトリウム、過酸化水素などが用いられる。
【００１２】
酸化剤の添加量は、少ないと生成するヨウ素が少なく、また多いと生成したヨウ素が液中へ析出することから、酸化剤を添加した後の液中のヨウ素／ヨウ素イオン(Ｉ／Ｉ−)比が約１／１になるように添加する。
【００１３】
酸化剤の添加温度は、通常、常温とする。
【００１４】
もう一方の原料である非水溶性担体の種類は、陰イオン交換樹脂あるいは活性炭が有効ヨウ素を高濃度に吸着できることから特に好ましい。非水溶性担体の使用量は、所望するヨウ素吸着濃度が得られるように、適宜選択される。
【００１５】
調製液と非水溶性担体との接触時のｐＨは、酸性が強いと接触操作後に得られるヨウ素吸着後の担体の酸性が強く、実用上好ましくないことから、通常接触前の調製液へアルカリを添加し、ｐＨ４〜７に調整する。接触時の温度は、室温で良い。また、接触時間は担体の種類によって異なり、通常１〜１０時間である。
【００１６】
この方法により得られるヨウ素系非水溶性固体防菌剤または殺菌剤は、高価なヨウ素およびヨウ化カリウムを使用しないことから経済的に安価であり、飲料用水、水泳プール、風呂および温泉などの浴用水、および空気中に浮遊する微生物と接触することにより殺菌力を現わす。

Further, as a method for producing an iodine-based water-insoluble solid anti fungal agents or bactericidal agents, a solution containing iodine and potassium iodide, method in which contact with a water-insoluble carrier is known.
[0005]
[Problems to be solved by the invention]
Method for manufacturing conventional iodine based water insoluble solid anti fungal agents or disinfectants, from the use of expensive iodine and potassium iodide, a problem that reduction in manufacturing cost is not economical and not easy Yes.
[0006]
An object of the present invention is to provide a method for producing efficiently and economically inexpensive iodine water insoluble solid anti fungal agents or fungicides.
[0007]
[Means for Solving the Problems]
The present invention, the content liquid which contains iodine and iodide ion was prepared by adding an oxidizing agent to the iodine absorption liquid obtained by blowing out method, the content liquid was contained iodine and iodine ions this non It is brought into contact with a water-soluble carrier.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the manufacturing method of the iodine-based non-water soluble solid anti fungal agents or fungicides of the present invention.
[0009]
Obtained by the blowing out method, which is a method in which a chlorine-based oxidant is introduced into an aqueous solution that dissolves iodine ions to convert the iodine ions into free iodine, then expelled with air and absorbed into a reducing solution such as sodium bisulfite. The iodine absorption liquid is used as a raw material.
[0010]
After preparing the solution containing which contains iodine and iodine ions by adding an oxidizing agent to the iodine absorption liquid obtained by the blowing-out method, contacted with water-insoluble carrier.
[0011]
As the type of oxidizing agent added to the iodine absorbing solution obtained by the blowing out method, chlorine, sodium hypochlorite, hydrogen peroxide, etc. are usually used.
[0012]
When the addition amount of the oxidizing agent is small, less iodine is produced, and when the addition amount is large, the produced iodine is precipitated in the liquid. Therefore, iodine / iodine ions (I / I − ) in the liquid after the addition of the oxidizing agent Add so that the ratio is about 1/1.
[0013]
The addition temperature of the oxidant is usually set to room temperature.
[0014]
The type of the water-insoluble carrier, which is the other raw material, is particularly preferable because an anion exchange resin or activated carbon can adsorb effective iodine at a high concentration. The amount of the water-insoluble carrier used is appropriately selected so that a desired iodine adsorption concentration can be obtained.
[0015]
The pH at the time of contact between the preparation liquid and the non-water-soluble carrier is that, if the acidity is strong, the acidity of the support after iodine adsorption obtained after the contact operation is strong, which is not preferable for practical use. Add and adjust to pH 4-7. The temperature at the time of contact may be room temperature. The contact time varies depending on the type of carrier and is usually 1 to 10 hours.
[0016]
Water-insoluble solid anti fungal agents or fungicides iodine obtained by this method is economically inexpensive since it does not use an expensive iodine and potassium iodide, potable water, bath such as swimming pools, baths and hot springs Bactericidal power is manifested by contact with water and microorganisms floating in the air.
[0017]
