Sodium Dichloroisocyanurate (SDIC), a chemical compound with CAS number 2893-78-9, is a cornerstone in disinfection and sanitation across numerous industries. Its unique chemical structure and properties make it a highly effective and stable source of active chlorine. As a leading producer and supplier, we are dedicated to providing high-quality SDIC and educating our clients on its characteristics and production.

Understanding the Chemistry of SDIC:

SDIC, chemically known as 1,3-dichloro-s-triazine-2,4,6-trione sodium salt, is a white crystalline powder or granule with a distinctive bleach-like odor. Its molecular formula is C3Cl2N3NaO3. A key characteristic is its high content of available chlorine, typically ranging from 56% to 60%, which is released upon dissolution in water through hydrolysis. This process generates hypochlorous acid (HOCl), the primary biocidal agent.

Key chemical properties include:

  • Solubility: SDIC is highly soluble in water, facilitating easy application. Its solubility rate ensures rapid release of active chlorine.
  • Stability: Compared to liquid bleach (sodium hypochlorite), solid SDIC exhibits superior stability, particularly in storage, with minimal loss of available chlorine even in humid conditions. This makes it a preferred choice for long-term inventory.
  • pH Profile: In aqueous solutions, SDIC maintains a slightly acidic to neutral pH, making it less corrosive to materials than highly alkaline or acidic disinfectants. This characteristic is beneficial for equipment longevity and worker safety.
  • Reactivity: As a strong oxidizing agent, SDIC is reactive with organic materials, reducing agents, and certain other chemicals. Proper handling and storage are crucial to prevent hazardous reactions.

Production and Manufacturing Excellence:

The synthesis of SDIC typically involves the chlorination of cyanuric acid or its sodium salt. Manufacturers meticulously control reaction conditions, such as pH and temperature, to ensure product purity and safety, avoiding the formation of unstable by-products. The production process demands precision to achieve consistent particle size distribution (e.g., 8-30 mesh granules) and high available chlorine content, which are critical parameters for performance.

When you seek to buy SDIC, especially in bulk, partnering with a reputable SDIC supplier China guarantees access to products manufactured under stringent quality controls. Experienced manufacturers understand the importance of consistent output and adhere to international standards.

Handling and Safety Precautions:

As a strong oxidizer, SDIC must be handled with care. It should be stored in a cool, dry place, away from combustible materials, acids, and ammonia compounds. Inhalation of dust and direct contact with skin and eyes should be avoided; appropriate personal protective equipment (PPE) such as gloves, eye protection, and respiratory masks are recommended during handling. For those interested in specific forms, understanding the 'SDIC effervescent tablet' preparation and handling is also important.
