PROPYLENE CARBONATE

Propylene carbonate (PC) is a clear, odorless, and highly versatile organic compound with a chemical structure featuring a cyclic carbonate ester. It is widely recognized for its excellent solvency, high boiling point, and low toxicity. Propylene carbonate is commonly used as a solvent, electrolyte component in batteries, and intermediate in chemical synthesis. Its biodegradability and low environmental impact make it a preferred choice in many industries.

Safety and Handling

• Hazards:
  • Low toxicity but can cause mild irritation to the skin, eyes, and respiratory tract.
  • Combustible at high temperatures, posing a moderate fire risk.
• Precautions:
  • Personal Protective Equipment (PPE): Wear protective gloves, goggles, and appropriate clothing when handling the substance.
  • Ventilation: Ensure adequate ventilation when using propylene carbonate in confined areas to prevent vapor accumulation.
  • Storage: Store in a cool, dry, and well-ventilated location away from heat and open flames. Use sealed containers to prevent moisture absorption.
• First Aid:
  • Eye Contact: Rinse eyes immediately with water for 15 minutes. Seek medical attention if irritation persists.
  • Skin Contact: Wash skin thoroughly with soap and water. Remove contaminated clothing.
  • Inhalation: Move to fresh air and seek medical help if symptoms such as coughing or dizziness occur.
  • Ingestion: Rinse mouth with water and do not induce vomiting unless directed by a medical professional. Seek immediate medical attention.
