Sodium dichloroisocyanurate

255.98 g/mol (dihydrate) Sodium dichloroisocyanurate (INN: sodium troclosene, troclosenum natricum or NaDCC or SDIC) is a chemical compound widely used as a cleansing agent and disinfectant. It is a colorless, water-soluble solid. The dihydrate is also known (51580-86-0 ) as is the potassium salt (2244-21-5 ). Sodium dichloroisocyanurate (INN: sodium troclosene, troclosenum natricum or NaDCC or SDIC) is a chemical compound widely used as a cleansing agent and disinfectant. It is a colorless, water-soluble solid. The dihydrate is also known (51580-86-0 ) as is the potassium salt (2244-21-5 ). It is mainly used as a disinfectant, biocide and industrial deodorant. It is found in some modern water purification tablets/filters. It is more efficient than the formerly used halazone water disinfectant. In these applications, it is a slow-release source of chlorine in low concentrations at a relatively constant rate. As a disinfectant, it is used to sterilize drinking water, swimming pools, tableware and air, and to fight against infectious diseases as a routine disinfection agent. It can be used as a preventative; for disinfection and environmental sterilization, for example in livestock, poultry, fish and silkworm raising; bleaching textiles and cleaning industrial circulating water and also to prevent wool from shrinking, In one notably interesting experiment, a concentrated solution of NaDCC and a dilute solution of copper (II) sulphate are mixed, producing an intense lilac precipitate of the complex salt sodium copper dichloroisocyanurate. The reactions between Dichloroisocyanurate salts (Na, K, Li, Ba, Ca) and transition metal salts (Ni, Cu, Cd) are described in patent US 3'055'889.The overall reaction is: Sodium dichloroisocyanurate is used to show chemiluminescence as it emits red light upon decomposition by concentrated (130 vol, 35%) hydrogen peroxide.
