Description
【０００１】
【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とヨウ素イオン含有液とを調製し、この調製したヨウ素とヨウ素イオン含有液と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、ヨウ素とヨウ素イオン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表わす。
【００１７】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for producing an iodine-based water-insoluble solid antibacterial agent.
[0002]
[Prior art]
BACKGROUND ART Iodine-based water-insoluble solid disinfectants are important substances as disinfectants for microorganisms floating in air, such as drinking water, swimming pool water, bath water such as baths and hot springs, and the like.
[0003]
Conventionally, as iodine-based water-insoluble solid disinfectants, cyclodextrin described in JP-A-51-88625, chitosan described in JP-A-54-74885, and JP-A-59-193189 are disclosed. Japanese Patent Application Laid-Open No. 10-245403 discloses a plastic bead, an anion exchange resin described in JP-A-60-218312, an activated carbon described in JP-A-60-224607, and JP-A-10-245403. A composition in which iodine is supported by using a porous inorganic compound or the like as a carrier is known.
[0004]
In addition, as a method for producing an iodine-based water-insoluble solid antibacterial agent, a method is known in which a solution containing iodine and potassium iodide is brought into contact with a water-insoluble carrier.
[0005]
[Problems to be solved by the invention]
The conventional method for producing a water-insoluble solid antibacterial agent for iodine uses expensive iodine and potassium iodide, and thus has a problem that the production cost is not easily reduced and is not economical.
[0006]
An object of the present invention is to provide a method for producing an iodine-based water-insoluble solid antibacterial agent that is efficient and economically inexpensive.
[0007]
[Means for Solving the Problems]
The present invention provides an iodine-absorbing liquid obtained by a blowing-out method, in which an oxidizing agent is added to prepare an iodine- and iodine-ion-containing liquid, and the prepared iodine- and iodine-ion-containing liquid are brought into contact with a water-insoluble carrier. It is.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the method for producing the iodine-based water-insoluble solid antibacterial agent of the present invention will be described.
[0009]
A chlorine-based oxidizing agent is added to an aqueous solution that dissolves iodine ions, the iodine ions are converted into free iodine, then expelled with air, and absorbed by a reducing solution such as sodium bisulfite to obtain a blowing-out method. The raw material is an iodine absorption liquid.
[0010]
An oxidizing agent is added to the iodine-absorbing solution obtained by the blowing-out method to prepare a solution containing iodine and iodine ions, and then brought into contact with a water-insoluble carrier.
[0011]
As the type of the oxidizing agent to be added to the iodine absorbing solution obtained by the blowing-out method, usually, chlorine, sodium hypochlorite, hydrogen peroxide and the like are used.
[0012]
When the amount of the oxidizing agent is small, the generated iodine is small, and when the amount is large, the generated iodine precipitates in the liquid. Therefore, the iodine / iodine ion (I / I − ) in the liquid after the oxidizing agent is added. Add so that the ratio is about 1/1.
[0013]
The temperature at which the oxidizing agent is added is usually 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 prepared solution and the water-insoluble carrier is such that the acidity of the carrier after iodine adsorption obtained after the contact operation is strong when the acidity is strong, which is not practically preferable. 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 the carrier, and is usually 1 to 10 hours.
[0016]
The iodine-based water-insoluble solid disinfectant obtained by this method is economically inexpensive because it does not use expensive iodine and potassium iodide, and is used for drinking water, bathing water for swimming pools, baths and hot springs, and Expresses bactericidal activity by contact with microorganisms floating in the air.
[0017]
【Example】
Next, the present invention will be described more specifically with reference to examples.
[0018]
Example 1
