Understanding Industrial Grade Calcium Hypochlorite

Chemical Properties and Specifications

Calcium Hypochlorite, with CAS Number 7778-54-3 and chemical formula Ca(ClO)₂, is a white powdered or granular solid compound characterized by its strong chlorine odor. The molecular weight stands at approximately 142.98, making it a stable and efficient oxidizing agent for various industrial applications.

The industrial grade typically comes in two primary concentration levels:

• 65% Available Chlorine: Standard grade for general water treatment and disinfection
• 70% Available Chlorine: Premium grade for specialized industrial applications

Both grades are classified under UN Number 2880, Hazard Class 5.1, indicating their oxidizing properties requiring careful handling and transportation protocols.

Key Industrial Applications

Industrial Grade Calcium Hypochlorite serves multiple critical functions across various sectors:

Water Treatment: Municipal water facilities and swimming pool operators rely on calcium hypochlorite for effective disinfection, eliminating harmful bacteria and microorganisms while maintaining water quality standards.

Industrial Bleaching: Textile manufacturers, paper mills, and pulp processing facilities utilize this compound for bleaching processes, achieving consistent whiteness and quality in final products.

Sanitation and Disinfection: Healthcare facilities, food processing plants, and public institutions depend on calcium hypochlorite solutions for comprehensive sanitation protocols.

Chemical Manufacturing: As a raw material, it serves various chemical synthesis processes requiring controlled oxidation reactions.
