Manufacturer Supply High Purity Sodium Dichloroisocyanurate CAS 2893-78-9

Chemical Structure: SDIC is derived from cyanuric acid by replacing three hydroxyl (-OH) groups with two chlorine (-Cl) atoms and a sodium (Na^+) ion. Each SDIC molecule contains two chlorine atoms and one cyanuric acid moiety.

Physical Properties:

• Appearance: SDIC is typically available as a white crystalline powder, granules, or tablets, with a slight chlorine odor.
• Solubility: It is soluble in water, and its solubility increases with temperature. When dissolved in water, it forms a slightly acidic solution due to the hydrolysis of the chlorine atoms.
• Stability: SDIC is relatively stable under normal storage conditions but decomposes slowly in the presence of moisture and heat, releasing chlorine gas.

Disinfection and Sanitization:

• SDIC is a powerful disinfectant and sanitizer that effectively kills bacteria, viruses, fungi, and algae.
• When dissolved in water, SDIC releases hypochlorous acid (HOCl) and hypochlorite ions (OCl^-), which are potent oxidizing agents that destroy microbial cells by disrupting their cell walls and metabolic processes.
• It is commonly used for disinfecting water in swimming pools, spas, cooling towers, and industrial water treatment systems to control microbial growth and prevent waterborne diseases.

Algae Control:

• SDIC is widely used as an algicide to prevent the growth of algae in water bodies, such as swimming pools, ponds, lakes, and reservoirs.
• It inhibits the photosynthesis and respiration of algae cells, leading to their death and subsequent removal from the water.
• SDIC is particularly effective against green algae, blue-green algae (cyanobacteria), and other types of algae commonly found in aquatic environments.

Bleaching and Oxidizing Agent:

• Similar to trichloroisocyanuric acid (TCCA), SDIC can be used as a bleaching agent in textile industry for whitening fabrics and removing stains.
• It is also employed in household cleaning products, such as laundry detergents and bleaches, for its oxidizing and bleaching properties.
• SDIC can oxidize and decompose organic compounds, breaking down organic stains and soils through oxidation reactions.

Safety Considerations:

• SDIC should be handled with care, as it can irritate the skin, eyes, and respiratory tract upon contact or inhalation of dust or fumes.
• Proper protective equipment, such as gloves, goggles, and respiratory protection, should be worn when handling SDIC products.
• It is important to follow recommended dosage and application guidelines to avoid overexposure and adverse effects on human health and the environment.

Environmental Impact:

• SDIC can release chlorine gas and hypochlorous acid upon decomposition, which can be harmful to aquatic life and ecosystems if released in large quantities.
• Spills or discharges of SDIC should be properly contained and neutralized to prevent environmental contamination and minimize adverse effects on water quality and aquatic organisms.
