Sodium Dichloroisocyanurate Dihydrate, also known as SDIC, is a chemical compound with the formula C3Cl2N3NaO3.2H2O. It is a white granular that is highly soluble in water. This compound is a derivative of isocyanuric acid and is widely used for its disinfectant properties.
SDIC dihydrate has the characteristics of high efficiency, broad spectrum, safety and stability. It can release hypochlorous acid in water and destroy the proteins on the surface of microorganisms through oxidation, thereby killing various microorganisms. As an important broad-spectrum bactericide and disinfectant, SDIC is widely used in industry, agriculture, epidemic prevention and other fields.

There are two main methods for manufacturing sodium dichloroisocyanurate dihydrate: one is direct synthesis and the other is metathesis.
The direct synthesis method uses chlorine, cyanuric acid and sodium hydroxide as raw materials, reacts under certain temperature and pressure conditions, and then goes through steps such as crystallization, separation, and drying. The metathesis method uses sodium chloride and cyanuric acid as raw materials, carries out a metathesis reaction under certain conditions, and then goes through steps such as crystallization, separation, and drying.
