|Section2= |Section3= |Section7= |Section8= }} Hypochlorous acid is a weak acid with the chemical formula HClO. It forms when chlorine dissolves in water, and it is HClO that actually does the disinfection when chlorine is used to disinfect water for human use. It cannot be isolated in pure form due to rapid equilibration with its precursor. HClO is an oxidizer, and as its sodium salt sodium hypochlorite, (NaClO), or its calcium salt calcium hypochlorite, (Ca(ClO)2) is used as a bleach, a deodorant, and a disinfectant. ==Uses== In organic synthesis, HOCl converts alkenes to chlorohydrins.〔Unangst, P. C. "Hypochlorous Acid" in ''Encyclopedia of Reagents for Organic Synthesis'' (Ed: L. Paquette) 2004, J. Wiley & Sons, New York. 〕 In biology, hypochlorous acid is generated in activated neutrophils by myeloperoxidase-mediated peroxidation of chloride ions, and contributes to the destruction of bacteria.〔 In the cosmetics industry it is used as a skin cleansing agent, which benefits the body's skin rather than causing drying. It is also used in baby products, because baby skin is particularly sensitive and can be easily irritated. In water treatment, hypochlorous acid is the active sanitizer in hypochlorite-based products (e.g. used in swimming pools). In food service and water distribution, specialized equipment to generate weak solutions of HOCl from water and salt is sometimes used to generate adequate quantities of safe (unstable) disinfectant to treat food preparation surfaces and water supplies.〔(''Disinfection of Facility H2O'' ).〕〔(''Water Works:'' ) ''Hyatt's New Disinfectant/Cleaner Comes from the Tap'', ''Bloomberg Businessweek''.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hypochlorous acid」の詳細全文を読む スポンサード リンク
