Abstract

본 발명은 강한 산화작용 특성으로 인하여 살균, 소취 또는 표백제로 사용되는 안정화이산화염소 수용액의 제조방법에 관한 것으로, 아염소산나트륨과 무기산을 혼합하거나 아염소산나트륨, 차아염소산나트륨 및 무기산을 혼합하여 안정화 이산화염소 수용액을 제조함에 있어 여기에 소량의 황성화제를 첨가하여 유리 이산화염소의 함유량을 최대한 증가시키는 것을 기술적 특징으로 한다.The present invention relates to a method for preparing a stabilized chlorine dioxide aqueous solution used as a sterilization, deodorant or bleaching agent due to strong oxidation properties, stabilized by mixing sodium chlorite and inorganic acid or by mixing sodium chlorite, sodium hypochlorite and inorganic acid In preparing an aqueous chlorine solution, it is a technical feature to add a small amount of sulfurizing agent to increase the content of free chlorine dioxide as much as possible.

상기 본 발명의 활성화제로는 트리클로로아이소시아누르산, 소디움다이클로로아이소시아누르산, 다이메칠다이데실암모니움클로라이드 또는 다이메칠벤질암모니움클로라이드가 바람직하다. 본 발명의 방법에 의해 제조된 안정화 이산화염소 수용액은 탄산염을 사용하지 않더라도 용액의 pH가 중성부위에서 안정하며 유리 이산화염소의 농도가 종래의 방법에 의해 제조된 것에 비해 휠신 높다는 장점이 있다.As the activator of the present invention, trichloroisocyanuric acid, sodium dichloroisocyanuric acid, dimethyldidecyl ammonium chloride or dimethylbenzyl ammonium chloride is preferable. Stabilized chlorine dioxide aqueous solution prepared by the method of the present invention has the advantage that the pH of the solution is stable at the neutral site even if carbonate is not used, and the concentration of free chlorine dioxide is higher than that prepared by the conventional method.
