Product Description

Product Description

Basic Information

• Product Name: Sodium Dichloroisocyanurate (SDIC)/ Sodium Dichloroisocyanurate Dihydrate
• Chemical Formula: C3Cl2N3NaO3/ C3Cl2N3NaO3.2H2O
• Molecular Weight: 219.95/ 255.98
• CAS Number: 2893-78-9/ 51580-86-0
• Appearance: White or off-white crystalline powder/granules with a pungent odor of hypochlorous acid
• Melting Point: ~240°C (decomposes)
• Solubility: Highly soluble in water (aqueous solution is acidic); slightly soluble in ethanol; insoluble in chloroform and diethyl ether

Application Fields

1. Disinfection and Sterilization
   • Water Treatment: Used for disinfection of drinking water, swimming pools, and industrial circulating water to eliminate algae and odors.
   • Hygiene and Epidemic Prevention: Environmental disinfection in hospitals, hotels, and households; sterilization and bleaching of tableware and fabrics.
   • Livestock and Poultry Farming: Disinfection of barns and equipment to prevent infectious diseases (e.g., avian influenza, swine fever).
2. Agriculture and Aquaculture
   • Control of crop diseases (e.g., powdery mildew, downy mildew) and elimination of pathogens/parasites in aquaculture.
3. Industrial Applications
   • Textile and Dyeing: As a mild bleaching agent for cotton, linen, and wool without damaging fibers.
   • Paper Industry: Bleaching of pulp to remove lignin and colorants.
   • Oilfield Water Treatment: Inhibit microbial growth to prevent pipeline blockages and equipment corrosion.
4. Food Processing
   • Disinfection of food processing equipment and containers (with strict control of residue levels to meet food safety standards).

Safety and Storage

• Toxicity and Hazards
  • Low Toxicity: Mildly irritating to skin, eyes, and respiratory tract; high-concentration exposure may cause burns.
  • Environmental Impact: Excessive use may lead to chlorine pollution in water bodies; discharge concentrations must be regulated.
• Safety Precautions
  • Wear protective gloves, masks, and goggles; avoid direct skin contact and inhalation of dust.
  • Never mix with acidic substances (e.g., hydrochloric acid, acetic acid), as this may trigger violent reactions and release toxic chlorine gas (Cl2).
• Storage Conditions
  • Store in a sealed container in a cool, dry, ventilated area, away from fire sources, heat, and reducing agents. Protect from moisture and direct sunlight.

Differences from Anhydrous SDIC

Property	Sodium Dichloroisocyanurate Dihydrate	Anhydrous Sodium Dichloroisocyanurate
Water Content	Contains 2 molecules of water (13.2% by weight)	No water molecules
Molecular Weight	255.98	219.95
Stability in Humidity	More stable short-term in moist conditions	Prone to caking or chlorine loss in high humidity
Chlorine Release Rate	Slightly slower due to hydration	Faster dissolution and chlorine release
Typical Uses	General disinfection, bleaching in wet environments	Industrial applications requiring high chlorine efficiency
