Sodium Dichloroisocyanurate is an inorganic compound with the molecular formula C3Cl2N3NaO3. It is a colorless and water soluble solid, and sometimes also appears as a white, crystalline powder. It has a strong chlorine odor. It is the sodium salt of dichloroisocyanuric acid and its IUPAC name is sodium 3,5-dichloro-2,4,6-trioxo-1,3,5-triazinan-1-ide. It also has other common names such as sodium troclosene, sodic troclosene.
The dichloroisocyanuric acid is slurried in water and reacted with sodium hydroxide to produce sodium dichloroisocyanurate.
The sodium dichloroisocyanurate crystals obtained are isolated by filtration. The crystals are flash dried with hot air to form a dry powder, that is then compacted and granulated.
It is primarily used for spa sanitation. It is also present in commercial dishwasher formulations. It is mainly a disinfectant, biocide, industrial deodorant and detergent. It is also used as a preventive for disinfection and environmental sterilization. It is also used in the sterilization of drinking water.
The sodium salt of dichloroisocyanuric acid is used in the textile industry as a bleaching agent for fabrics. Its other uses in the textile industry are to prevent wool from shrinking and raising silkworm for the production of silk used in textiles.
Waste water treatment
The sodium salt of dichloroisocyanuric acid is used in the cleaning of industrial circulating water. It is more efficient than the formerly used halazone water disinfectant and hence is found in modern day water purification tablets and filters.
It is used to show chemi-luminescence as it emits red light upon decomposition by hydrogen peroxide.
