Propylene Carbonate CAS#108-32-7 Products Description
Cyclic carbonates are classified into five-, six-, and seven-membered ring compounds, as well as macrocyclic carbonates with rings containing more than seven members. Among these, propylene carbonate and ethylene carbonate are the most commonly used.
Ethylene carbonate is a highly polar solvent characterized by its high boiling point and also serves as an essential raw material in surfactant manufacturing. It has a wide range of industrial applications, including plastics production, textile printing and dyeing, polymer synthesis, gas separation, and electrochemical processes.
