极不稳定。工业品次氯酸钠是无色或淡黄色的液体，俗称漂白水，含有效氯100－140g/l。次氯酸钠易溶于水，溶于水后生成烧碱及次氯酸，次氯酸再分解生成氯化氢和新生氧，新生氧的氧化能力很强，所以次氯酸钠也是强氧化剂。次氯酸钠易水解，故不宜久存。其稳定度受光、热及重金属阳离子和PH值的影响。具有刺激味，且伤害皮肤。 次氯酸钠水溶液主要用于造纸、纺织工业的漂白，以及水处理和杀菌消毒，还用于水合肼等合成。 Sodium hypochlorite is used as a disinfectant and a bleaching agent. It is used as a destainer involved in removing of mold stains, dental stains arises by fluorosis. It finds application in laundry detergents. Its aqueous solution is used as household bleach for sanitizing smooth surfaces. In a water treatment plant, it is utilized for treating dilute cyanide waste water like electroplating wastes. It is an oxidizing agent used with phase transfer catalyst to convert alcohols into corresponding carbonyl compounds. It is an important reactant in Hofmann rearrangement to prepare primary amine from primary amide.
