Sodium Dichloroisocyanurate

Brief overview

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.

Manufacturing Process

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.

Disinfectant
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.

Textile Industry
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.

Other applications
It is used to show chemi-luminescence as it emits red light upon decomposition by hydrogen peroxide.
