What is Ethylene Carbonate？

Ethylene Carbonate is a cyclic carbonate ester that is a white crystalline solid at room temperature and becomes a colorless liquid above its melting point of 36-37°C. It is soluble in water and most organic solvents. The compound exhibits high dielectric constant, high boiling point, and excellent chemical stability, making it a key component in lithium-ion battery electrolytes and various industrial applications.
