General description

Propylene carbonate can be synthesized from propylene oxide and CO2. Optically active form of propylene carbonate can be prepared from the reaction between CO2 and racemic epoxides. Decomposition of propylene carbonate on the graphite electrode in lithium batteries results in the formation of a lithium intercalated compound.

Propylene carbonate is a cyclic carbonate that is commonly used as a solvent and as a reactive intermediate in organic synthesis. It is being considered as a potential electrochemical solvent due to its low vapor pressure, high dielectric constant and high chemical stability.


Propylene carbonate may be used as a solvent for the asymmetric hydrogenation of nonfunctionalized olefins.
