Introduction
Name: Propylene carbonate
CAS No: 108-32-7
Molecular Formula: C4H6O3
Propylene carbonate has a strong absorption capacity for carbon dioxide, and the state properties are stable. In industry, it is prepared by addition of propylene oxide and carbon dioxide under certain pressure and then distillation under reduced pressure.
Propylene carbonate can be used as oil solvent, spinning solvent, extractant of olefin and aromatic hydrocarbon, carbon dioxide absorbent, dispersant of water-soluble dye and pigment, etc.
