R2NSO3H(1)
(式中、Rは独立して水素原子または炭素数1〜8のアルキル基である。)
本実施形態に係る水処理剤組成物は、例えば、水にアルカリを混合した後、臭素系酸化剤とスルファミン酸化合物を混合することにより得られる。
本実施形態に係る水処理剤組成物は、冷却水等の工業用水システムの水処理や、生物付着汚染の進んだ配管洗浄等の水処理方法に用いることができる。
窒素雰囲気下で、液体臭素:16.9重量%(wt%)、スルファミン酸:10.7重量%、水酸化ナトリウム:12.9重量%、水酸化カリウム:3.94重量%、水:残分を混合して、安定化次亜臭素酸組成物を調製した。安定化次亜臭素酸組成物のpHは14、全塩素濃度は7.5重量%であった。全塩素濃度は、HACH社の多項目水質分析計DR/4000を用いて、全塩素測定法(DPD(ジエチル−p−フェニレンジアミン)法)により測定した値(mg/L asCl2)である。安定化次亜臭素酸組成物の詳細な調製方法は以下の通りである。
電極タイプ:ガラス電極式
pH測定計:東亜ディーケーケー社製、IOL−30型
電極の校正:関東化学社製中性リン酸塩pH(6.86)標準液(第2種)、同社製ホウ酸塩pH(9.18)標準液(第2種)の2点校正で行った
測定温度:25℃
測定値:測定液に電極を浸漬し、安定後の値を測定値とし、3回測定の平均値
上記安定化次亜臭素酸組成物の調製例に従い、表1に示す量で、水、液体臭素、スルファミン酸、アルカリを含む製剤を調製し、それぞれ製剤の凍結点、pHを測定した。凍結点は、それぞれの製剤を所定温度で24時間保管し、測定した。
◎:凍結点低下効果(a)+(b)が、−1℃未満
〇:凍結点低下効果(a)+(b)が、0℃未満−1℃以上
×:凍結点低下効果(a)+(b)が、0℃以上
