Description
臭素に基づく殺生物剤は、冷却水の微生物抑制及び廃棄物処理システムの消毒のために塩素化−脱塩素化を超える殺生物的利点が証明された。水処理産業はこれらの利点を比較的高いpH値において原価効率の高い管理であり、アンモニアの存在下で殺生物活性における損失がほとんどなく、且つバクテリア、藻類及び軟体動物の有効な抑制であると認めている。
BrCl+H2O→HOBr+HCl (2)
臭素及び塩化臭素の性質を表1において比較する。
本発明は、中でも、同じ成分から形成され、かくしておそらく濃度に関する以外は同じかもしくは非常に類似の化学組成を有する現在商業的に入手可能なもっと希薄な殺生物性水溶液よりさえ高い、驚くほど高い保存安定性を有する非常に濃厚な活性臭素−含有殺生物性水溶液を提供する。さらに本発明は中でも、固体状態で保存及び運送するのに適しており、且つ産業もしくは再生(recreational)水システムに固体の形態で直接添加するための有効な殺生物性添加物として、あるいは産業もしくは再生水システムへの添加のための所望の濃度の高度に活性な殺生物性水溶液もしくは水性スラリの生成のための原料として用いることができる新規な高度に水溶性の固体状態臭素−含有殺生物性組成物を含む。かくして本発明は、高度に有効な活性臭素−含有殺生物性組成物の製造及び輸送に伴う保存空間及び運送コストを減少させることを可能にする。言い換えると、より高度に濃厚な殺生物剤の水溶液又は個体形態における殺生物剤自身を提供することにより、本発明の殺生物性生成物の保存空間、運送体積及び運送コストを有意に減少させることができる。さらに、本発明の固体状態殺生物性生成物の望ましい保存安定性ならびにより希薄な商業的に入手可能な溶液と比較して本発明のより高度に濃厚な溶液の驚くべき保存安定性の向上はなお一層本発明の利点である。本発明のより高度に濃厚な殺生物性組成物が、驚くべきことに、同じ成分から作られるより希薄な商業的に入手可能な組成物と等しいかもしくはそれより低い結晶化温度を有し得ることも見出された。
臭素源、例えば塩化臭素又は臭素をスルファミン酸のアルカリ金属塩の水溶液中に導入する場合、追加のアルカリ金属塩基も溶液中に導入することにより(所望通り継続的又は断続的に)、例えばアルカリ金属塩基の水溶液の共−供給により、得られる溶液の所望のpHを7もしくはそれより高く保持するのが望ましい。濃厚水溶液がドラム中で保存されるべき場合、10もしくはそれより高い、そして好ましくは12.5〜13.5の範囲内のそのような溶液のpHを有するのが望ましい。必要なら、pHは14のように高いことができる。

1)ジャケット付きガラス管中に約30mLの試料を量り込む。
2)播種(seeding)材料として0.03gの粉砕されたガラスを試料に加える。
3)ゴム栓/温度計/らせん攪拌機(helical stirrer)アセンブリを試料中に導入する。(プローブの尖端は管の底から大体半インチに置かれなければならない)。
4)試料及びアセトンのレベルが大体等しくなるまで、管を冷却浴中で支える。
5)アセトン浴中の第2の温度プローブを、それが底又は側面に触れないように固定する。
6)試料の攪拌を開始し、ゆっくり且つ注意深くアセトン浴にドライアイスを加え始める。攪拌しながら攪拌機を試料中に保つ。攪拌機を試料から出さないようにする。これは試料中に気泡を形成させるであろう。
7)温度計ディスプレー上で温度が下がり始めるのを見る。管中の試料の温度はかなり安定した速度で下がるであう。予測される凍結点から大体10℃上で、冷却速度を約0.5℃/分に保持しなければならない。
8)冷却及び温度の監視を続ける。すべての試料が結晶化したら、試料を監視する。凍結点温度を短時間(10〜20秒)安定化させねばならない。過冷却が明らかなら、温度上昇の後に温度が安定化する凍結点温度をとる。試料が−46℃で結晶化しない場合、試験を停止する。
9)試料が室温に温まった後、結晶が溶液中に戻るかどうかを見るために調べる。
