Propylene carbonate is a colorless, odorless, and highly polar liquid that is widely used as a solvent and intermediate in chemical synthesis. It is valued for its high dielectric constant and low toxicity, making it suitable for applications in batteries, coatings, and pharmaceuticals.
🏭⚗️ Production
Propylene carbonate is commonly produced by the reaction of propylene oxide with carbon dioxide under controlled conditions, which results in a cyclic carbonate. This environmentally friendly process utilizes carbon dioxide as a raw material, contributing to sustainable chemical manufacturing.
🔬 Properties
The chemical formula of propylene carbonate is C₄H₆O₃ with a molar mass of approximately 102.09 g/mol. It appears as a clear, colorless liquid with a boiling point around 242 °C and a melting point near -48 °C. Propylene carbonate is highly soluble in water and many organic solvents and exhibits excellent chemical stability and low volatility.
🧪 Applications
Propylene carbonate is extensively used as a solvent in lithium-ion batteries, electrochemical applications, paints, and coatings. It also serves as a reaction medium and intermediate in organic synthesis. Additionally, it finds use in cosmetics and pharmaceuticals due to its low toxicity and solvent properties.
⚠️ Safety
Propylene carbonate is considered to have low toxicity but should still be handled with appropriate care. It may cause mild skin or eye irritation upon contact. It is recommended to use personal protective equipment such as gloves and goggles and to work in a well-ventilated area. The compound should be stored in a tightly sealed container away from strong oxidizers and heat sources.
