Propylene Carbonate CAS#108-32-7
Cyclic carbonates include five-, six-, and seven-membered ring structures, as well as macrocyclic carbonates with larger ring systems. Among these, ethylene carbonate (EC) and propylene carbonate (PC) are among the most commercially important and widely used compounds.
Ethylene Carbonate is a highly polar solvent characterized by excellent solvency, a high boiling point, and good thermal stability. It also serves as a valuable feedstock for surfactant manufacturing. Due to its versatile chemical and physical properties, EC is widely applied in plastics, textile printing and dyeing, polymer synthesis, gas separation, and electrochemical technologies, making it an important material for a broad range of industrial applications.
