Sodium dichloroisocyanurate (INN: sodium troclosene, troclosenum natricum or NaDCC or SDIC) is an inorganic compound. It is a colourless, water-soluble solid. It is a widely used cleansing agent and disinfectant. The dihydrate is also known (CAS# 51580-86-0) as is the potassium salt (CAS#2244-21-5).
It is mainly used as a disinfectant, biocide, industrial deodorant and detergent. It is found in some modern water purification tablets/filters. It is more efficient than formerly used halazone water disinfectant. In these applications, it is a source of slow release 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, fight against infectious diseases as routine disinfection.
It can be used as a preventive for disinfection and environmental sterilization, in raising silkworm, livestock, poultry and fish, and also can be used to prevent wool from shrinking, bleaching textiles and cleaning industrial circulating water.
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:
- CuSO4 + Na(C3N3O3Cl2) → Na2[Cu(C3N3O3Cl2)4] + ?
