Calcium hypochlorite

Chemical formula: Ca(ClO)₂

CAS: 7778-54-3

Description:
This substance appears as a fine, off-white to pale yellow powder with a pronounced chlorine odor, reflecting its high active chlorine content (typically 80–90%). It exhibits pH-dependent reactivity: under acidic conditions, it liberates elemental chlorine, whereas in alkaline media—or in the presence of suitable catalysts—it serves as a reliable source of molecular oxygen. The compound demonstrates excellent solubility in water, facilitating its use in aqueous formulations.

Key Uses:
  • Pulp and textile processing: employed as a potent bleaching agent for paper manufacturing and fabric whitening;
  • Water treatment: widely used for sanitizing swimming pool water, as well as for disinfecting municipal drinking water and industrial wastewater;
  • Corrosion mitigation: helps minimize oxidative damage to metal fixtures and structural components commonly found in aquatic environments;
  • Industrial oxidation: functions as a versatile chemical oxidant in processes such as sterilization, decontamination, and neutralization of hazardous gases;
  • Material preservation and manufacturing: applied in wood protection treatments, metallurgical operations, and surface finishing of fabricated metal goods.
