Product Description

Product Description

Basic Information

• Chemical Name: Chromic anhydride / Chromium trioxide
• Molecular Formula: CrO3
• Molecular Weight: 99.99 g/mol
• CAS Number: 1333-82-0

Physical and Chemical Properties

• Appearance: Dark red to dark purple rhombic crystals, hygroscopic (absorbs moisture easily).
• Melting Point: 196°C (decomposes upon heating).
• Density: Crystalline form: 2.7 g/cm³; Melt: 2.8 g/cm³.
• Solubility: Highly soluble in water, alcohols, sulfuric acid, and diethyl ether; insoluble in acetone.
• Chemical Activity:
  • Decomposes at its melting point and completely decomposes at boiling point.
  • Strong oxidizing agent: Contact with organic materials (e.g., alcohol, benzene) can cause combustion or explosion.
  • Highly corrosive to metals and tissues.

Applications

1. Metal Surface Treatment
   • Key material in electroplating industries for chromium plating on bicycles, sewing machines, etc., providing a bright finish and enhancing corrosion resistance.
2. Organic Synthesis
   • Powerful oxidant for converting alcohols to aldehydes or ketones; used in the production of dyes and pigments.
3. Glass and Ceramic Industries
   • Manufactures green and yellow pigments to impart vibrant colors to glass and ceramics.
4. Wood Preservation
   • Acts as a wood preservative to protect against fungal decay and insect damage.
5. Chemical Analysis
   • Used in laboratories for quantitative analysis, such as titrating organic and inorganic substances as a strong oxidant.

Safety and Environmental Considerations

• Health Hazards:
  • Highly toxic if inhaled or contacted; causes severe skin burns, respiratory damage, and eye irritation.
  • Hexavalent chromium (Cr6) in chromic anhydride is a known carcinogen, linked to lung cancer and DNA damage.
• Environmental Risks:
  • Contaminates water and soil; improper disposal leads to ecological harm.
  • Wastewater and residues must be treated via neutralization and reduction to convert Cr6 to less toxic Cr³ before discharge.

Storage and Handling

• Store in a dry, well-ventilated area, away from organic materials, reducing agents, and moisture.
• Use protective gear (gloves, goggles, respirators) during handling to prevent exposure.
