Product Description

1. Chemical Identification

• IUPAC Name: Potassium pentyl dithiocarbonate
• Synonyms: Potassium amyl xanthate, PAX
• CAS No.: 2720-73-2
• Molecular Formula: C₆H₁₁KOS₂
• Molecular Weight: ~202.38 g/mol
• EC Number: 220-306-7

 

2. Physical and Chemical Properties

• Appearance: Yellowish crystalline granules or powder.
• Odor: Strong sulfurous (rotten egg-like) odor.
• Solubility:
  • Freely soluble in water.
  • Slightly soluble in alcohols and organic solvents.
• Density: ~1.2-1.4 g/cm³.
• Melting Point: Decomposes before melting (starts at ~120-150°C).
• pH (1% solution): ~9-11 (alkaline).
• Stability:
  • Moisture-sensitive; decomposes in acidic conditions.
  • Releases toxic gases (e.g., CS₂, H₂S) on decomposition.

 

3. Handling and Storage

• Storage:
  • Store in a cool, dry, well-ventilated area.
  • Keep containers tightly sealed to prevent moisture absorption.
• Incompatibilities: Strong acids, oxidizers, moisture.
• Handling Precautions:
  • Use PPE (nitrile gloves, goggles, respirator).
  • Minimize dust generation.

 

4. Safety Information

• GHS Hazard Statements:
  • H302: Harmful if swallowed.
  • H315: Causes skin irritation.
  • H319: Causes serious eye irritation.
  • H335: May cause respiratory irritation.
  • H400: Very toxic to aquatic life.
• NFPA Ratings: Health: 3, Flammability: 1, Reactivity: 2.
• First Aid:
  • Inhalation: Move to fresh air; seek medical attention.
  • Skin Contact: Wash with soap and water.
  • Eye Contact: Flush with water for 15 minutes.
  • Ingestion: Rinse mouth; do NOT induce vomiting.

 

5. Applications

• Primary Use: Collector in froth flotation for sulfide ores (e.g., copper, lead, zinc, gold).
• Key Advantages:
  • Strong affinity for sulfide minerals due to longer alkyl chain (amyl group).
  • Effective in weakly alkaline to neutral pH conditions.

 

6. Environmental and Regulatory Information

• Environmental Impact:
  • Highly toxic to aquatic organisms; avoid release into water systems.
• Regulatory Compliance:
  • OSHA Hazard Classification: Toxic (Category 4).
  • Transport Classification**: UN 3342 (Flammable solid, PG III).
