Propylene Carbonate CAS#108-32-7
Cyclic carbonates include five-membered, six-membered, and seven-membered ring structures, as well as macrocyclic varieties containing more than seven ring atoms. Among these, propylene carbonate and ethylene carbonate are the most commonly employed.
Ethylene carbonate is a highly effective polar solvent characterized by a high boiling point, and it also serves as a key raw material in the production of surfactants. It finds extensive use across a range of industries, including plastics, textile printing and dyeing, polymer synthesis, gas separation, and electrochemical applications.
