Overview
Propylene carbonate (PC) is a polar aprotic solvent produced via the cycloaddition of carbon dioxide to propylene oxide. Its molecular formula is C4H6O3 with CAS No. 108-32-7.
Application
- Lithium-ion batteries: Primary electrolyte solvent for high-voltage systems.
- Polyurethanes: Non-isocyanate route precursor for polycarbonate polyols.
- Pharmaceuticals: High-purity extraction agent and reaction medium.
- Gas treatment: Absorbent for CO2 removal in natural gas processing.
Precautions
Store in tightly sealed containers away from moisture. Avoid inhalation of vapors; use appropriate PPE including chemical-resistant gloves and eye protection. Do not mix with strong oxidizers.
