Product Description
What Is Sodium Dichloroisocyanurate?
Sodium Dichloroisocyanurate (SDIC) is a widely used chemical compound that serves as a disinfectant, bactericide, and agent for water treatment. It releases chlorine upon dissolving in water, making it effective in sanitizing and disinfecting surfaces, pools, and drinking water. SDIC is also used in industrial water treatment, wastewater disinfection, and as a bleaching agent in the textile industry.
Preparation Method:
SDIC is synthesized by reacting cyanuric acid with chlorine gas or sodium hypochlorite in the presence of a base, such as sodium hydroxide. Through this process, sodium dichloroisocyanurate is produced, followed by crystallization and drying to yield the final product, available in either anhydrous or dihydrate form.

User Asked Question:
Q: What is the difference between Sodium Dichloroisocyanurate (SDIC) and Hydrogen Peroxide (H2O2)?
A: SDIC is a chlorine-based disinfectant, effective for long-term disinfection, while hydrogen peroxide is an oxidizing agent, ideal for organic matter breakdown. SDIC is more effective against a broader range of pathogens, including bacteria, viruses, and fungi, whereas hydrogen peroxide excels in bleaching and specific uses, like wound care.
