Sodium dichloroisocyanurate


Sodium dichloroisocyanurate is a chemical compound widely used as a cleansing agent and disinfectant. It is a colorless, water-soluble solid. The dihydrate is also known as is the potassium salt.

Uses

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 for disinfection and environmental sterilization, for example in livestock, poultry, fish and silkworm raising, for bleaching textiles, for cleaning industrial circulating water, and to prevent wool from shrinking.
In one notably interesting experiment, a concentrated solution of NaDCC and a dilute solution of copper sulfate are mixed, producing an intense lilac precipitate of the complex salt sodium copper dichloroisocyanurate. The reactions between dichloroisocyanurate salts and transition metal salts are described in patent . The overall reaction is:
Sodium dichloroisocyanurate is used to show chemiluminescence as it emits red light upon decomposition by concentrated hydrogen peroxide.
