1. PRODUCT IDENTIFICATION AND CHEMICAL IDENTITY

2. CHEMICAL STRUCTURE
2.1. Molecular Structure
Vanadium pentoxide is an inorganic compound of vanadium and oxygen. Vanadium ions (V⁵⁺) and oxide ions (O²⁻) are present in a 2:5 ratio. It has an orthorhombic crystal structure. It decomposes at high temperatures (above 800°C). It is sparingly soluble in water; soluble in acids and alkalis. It is an important catalyst and metallurgical material.

5.1. Chemical Reactions

• Reaction with Acids:
  V₂O₅ + 6HCl → 2VOCl₂ + Cl₂↑ + 3H₂O
  V₂O₅ + 2HNO₃ → 2V₂O₅·H₂O (Vanadic acid)

• Reaction with Alkalis (Vanadate Formation):
  V₂O₅ + 2NaOH → 2NaVO₃ + H₂O
  V₂O₅ + 6NaOH → 2Na₃VO₄ + 3H₂O

• Reduction (at High Temperature):
  V₂O₅ + 2H₂ → V₂O₃ + 2H₂O
  V₂O₅ + 5C → 2V + 5CO

18. CRITICAL WARNINGS AND BEST PRACTICES

CRITICAL WARNINGS:

• Highly Toxic: Vanadium pentoxide is fatal if swallowed or inhaled (H300, H330). Exposure must be strictly minimized.

• Carcinogenic: Classified as Carcinogen Category 1B (H350) under GHS. Prolonged exposure carries cancer risk.

• Environmental Hazard: Very toxic to aquatic life (H410). Release into water sources must be strictly prevented.

• Incompatibility: Reacts with strong reducing agents (H₂, C, CO) generating heat; may create fire and explosion risk.

• Powder Hazard: Fine powder form may cause respiratory tract irritation and systemic toxicity. Strict dust control measures must be taken.

• Recycling: Vanadium is a valuable metal; recovery from spent catalysts and vanadium redox batteries is possible.

BEST PRACTICE RECOMMENDATIONS:

• Storage:

  • Store in a cool, dry, and well-ventilated area.

  • Use moisture-proof, tightly closed containers.

  • Keep away from reducing agents, acids, and oxidizing agents.

  • Store at room temperature (15-25°C).

  • Store locked up.

• Handling:

  • Use in well-ventilated areas with local exhaust ventilation or under a fume hood.

  • Use a dust mask (P3 filter), protective goggles, chemically resistant gloves, and protective clothing.

  • Avoid dust formation and inhalation.

  • Wash hands thoroughly after handling.

  • Remove contaminated clothing and wash before reuse.

  • Ensure controlled conditions when working with acids and alkalis.

• Waste Management:

  • Dispose of in accordance with local regulations at licensed disposal facilities.

  • Do not discharge into water sources.

  • For large quantities, vanadium recycling and recovery should be considered (valuable metal).
