Sodium dichloroisocyanurate (INN: sodium troclosene,troclosenum natricum or NaDCC or SDIC) is a chemical compound widely used as a cleansing agent and disinfectant.[1] It is a colorless, water-soluble solid, produced as a result of reaction ofcyanuric acid withchlorine. The dihydrate is also known (51580-86-0 ) as is the potassium salt (2244-21-5 ).
It is mainly used as adisinfectant,biocide and industrialdeodorant. It is found in some modernwater purification tablets/filters. It is more efficient than the formerly usedhalazone 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 for disinfection and environmentalsterilization, for example in livestock, poultry, fish andsilkworm raising, forbleaching textiles, for cleaning industrial circulating water, and to prevent wool from shrinking.
The reaction between NaDCC and a dilute solution ofcopper (II) sulfate produces an intenselilac precipitate of the complex saltsodium copper dichloroisocyanurate. The reactions between dichloroisocyanurate salts (Na,K,Li,Ba,Ca) and transition metal salts (Ni,Cu,Cd) are described in patentUS 3,055,889. The overall reaction is:
Sodium dichloroisocyanurate reacts with concentrated (130 vol, 35%)hydrogen peroxide to createsinglet oxygen which emits red light upon decomposition .[2]
It is considered hazardous according to OSHA 29 CFR 1910.1200. High-level exposure can causereactive airways dysfunction syndrome (R.A.D.S.)[3]
