Descripción

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.

Application

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