Description
【０００１】
【発明の属する技術分野】
本発明は、除草剤、殺菌剤、人工透析機や医療器具の除菌剤として用いられている過酢酸水溶液に関する。
【０００２】
【従来の技術】
過酢酸濃度が高いほど該水溶液の除菌能力は向上し、現在、汎用過酢酸組成物として過酢酸濃度は高いもので６重量％程度のものが上市されている。しかしながら、これらの過酢酸組成物中の酢酸濃度は高く、除草剤等として使用した場合、土壌表面又は土壌中で分解し、地球温暖化の原因となるメタンガス及び二酸化炭素ガスを多量に発生する。また、雨水により土壌から流れ出した場合、河川水等のＣＯＤが上昇し、水質汚濁の原因ともなる。
【０００３】
【発明が解決しようとする課題】
本発明の目的は、過酢酸濃度が高く、かつ酢酸濃度が低い過酢酸水溶液を提供することにある。
【０００４】
【課題を解決するための手段】
発明者らは、上記について鋭意研究を重ねた結果、高濃度の過酸化水素水溶液及び酢酸を用い、過酢酸濃度６重量％以上、酢酸濃度１６重量％以下の水溶液が得られることを見出し本発明を完成させるに至った。
【０００５】
即ち、本発明は、過酢酸６〜１５重量％、過酸化水素３０〜５０重量％、酢酸３〜１６重量％からなり、かつ過酢酸と過酸化水素の合計が６０重量％以下であることを特徴とする過酢酸水溶液に関するものである。
【０００６】
【発明の実施の形態】
本発明の組成物は、種々の方法で製造できるが、過酸化水素３０〜５５重量部、酢酸８〜３０重量部及び残分として水を混合する方法が適用される。好ましくは、この組成物を得るにたる濃度の範囲内で出来るだけ高濃度の過酸化水素水溶液及び酢酸と必要量の触媒を混合し、過酢酸を生成させ、次いで所定濃度となるような水を添加する方法が好適に適用される。これは、過酸化水素３０〜５５重量部、酢酸８〜３０重量部及び水２２〜３６重量部を先ず混合、反応させて過酢酸を生成させた後、残部の水を添加する方法が適用される。
【０００７】
反応は室温で行ってもよいが、より短時間で平衡に達するように、３０〜７０℃程度に加温してもよい。ここで、硫酸、オルトリン酸等の触媒を０．０１〜３重量％添加して反応させるのが好ましい。また、安定剤は、製造直後に使用する場合には添加の必要はないが、それ以外の場合には０．０１〜３重量％程度添加することが好ましい。安定剤としては、広く一般に使用されているピロリン酸、ピロリン酸ナトリウム、ジピコリン酸、ホスホン酸系キレート剤等を添加することができる。
【０００８】
【実施例】
以下に実施例を挙げて本発明を更に詳しく説明するが、本発明はこれらの実施例によりその範囲を限定されるものではない。

【発明の効果】
本発明の組成物は、比較的高い過酢酸濃度を持ちながらも、酢酸分濃度が比較的低いために、環境に悪影響を及ぼさないものである。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an aqueous solution of peracetic acid that is used as a herbicide, a bactericide, an antidiabetic agent for an artificial dialysis machine or a medical instrument.
[0002]
[Prior art]
The higher the peracetic acid concentration, the better the sterilization ability of the aqueous solution. Currently, a general-purpose peracetic acid composition having a high peracetic acid concentration of about 6% by weight is marketed. However, the concentration of acetic acid in these peracetic acid compositions is high, and when used as a herbicide or the like, it decomposes in the soil surface or in the soil and generates a large amount of methane gas and carbon dioxide gas that cause global warming. Moreover, when it flows out from soil by rainwater, COD of river water etc. rises and causes water pollution.
[0003]
[Problems to be solved by the invention]
An object of the present invention is to provide a peracetic acid aqueous solution having a high peracetic acid concentration and a low acetic acid concentration.
[0004]
[Means for Solving the Problems]
As a result of intensive studies on the above, the inventors have found that an aqueous solution having a peracetic acid concentration of 6 wt% or more and an acetic acid concentration of 16 wt% or less can be obtained using a high concentration aqueous hydrogen peroxide solution and acetic acid. It came to complete.
[0005]
That is, the present invention comprises 6 to 15% by weight of peracetic acid, 30 to 50% by weight of hydrogen peroxide, 3 to 16% by weight of acetic acid, and the total amount of peracetic acid and hydrogen peroxide is 60% by weight or less. It relates to a characteristic aqueous peracetic acid solution.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The composition of the present invention can be produced by various methods, and a method of mixing 30 to 55 parts by weight of hydrogen peroxide, 8 to 30 parts by weight of acetic acid, and water as a residue is applied. Preferably, a hydrogen peroxide aqueous solution having a concentration as high as possible within the range of concentration for obtaining the composition and acetic acid and a required amount of catalyst are mixed to produce peracetic acid, and then water to obtain a predetermined concentration is added. The method of adding is applied suitably. This is a method in which 30 to 55 parts by weight of hydrogen peroxide, 8 to 30 parts by weight of acetic acid and 22 to 36 parts by weight of water are first mixed and reacted to form peracetic acid, and then the remaining water is added. The
[0007]
The reaction may be performed at room temperature, but may be heated to about 30 to 70 ° C. so that equilibrium is reached in a shorter time. Here, it is preferable to add 0.01 to 3 weight% of catalysts, such as a sulfuric acid and orthophosphoric acid, and to make it react. Further, the stabilizer does not need to be added when used immediately after production, but is preferably added in an amount of about 0.01 to 3% by weight in other cases. As the stabilizer, pyrophosphoric acid, sodium pyrophosphate, dipicolinic acid, phosphonic acid-based chelating agents and the like that are widely used in general can be added.
[0008]

Peracetic acid 15.0% by weight
Hydrogen peroxide 30.0% by weight
Acetic acid 15.5% by weight
Orthophosphoric acid 0.1% by weight
39.4% by weight of water
[0010]
Example 2
54.5 g of a 60 wt% aqueous hydrogen peroxide solution, 13.4 g of glacial acetic acid, 0.1 g of orthophosphoric acid, and 31.8 g of ion-exchanged water were mixed and allowed to stand at 25 ° C. for 6 days to obtain the following composition. .
Peracetic acid 6.0% by weight
Hydrogen peroxide 30.0% by weight
Acetic acid 8.7% by weight
Orthophosphoric acid 0.1% by weight
Water 55.2% by weight
[0011]
Comparative Example 18 g of a 60% by weight aqueous hydrogen peroxide solution, 36 g of glacial acetic acid, 0.2 g of concentrated sulfuric acid, 0.2 g of pyrophosphoric acid and 31.8 g of ion-exchanged water were mixed and allowed to stand at 30 ° C. for 3 days. Got.
7.1% by weight peracetic acid
Hydrogen peroxide 7.7% by weight
Acetic acid 30.9% by weight
Sulfuric acid 0.2% by weight
Pyrophosphate 0.2 wt%
53.9% by weight of water
In the composition of the comparative example, although the concentration of peracetic acid is about one-half that of Example 1, the concentration of acetic acid is about twice, which is not preferable from the viewpoint of environmental protection.
[0012]
【The invention's effect】
The composition of the present invention has a relatively high peracetic acid concentration, but does not adversely affect the environment due to a relatively low acetic acid concentration.
