Propylene carbonate (often abbreviated PC) is an organic compound with the formula CH3C2H3O2CO. It is a carbonate ester derived from propylene glycol. This colorless and odorless liquid is useful as a polar, aprotic solvent. Propylene carbonate is chiral but is used exclusively as the racemic mixture.
Propylene carbonate is often used as a solvent for electrolysis.
Propylene carbonate is a colorless liquid freezing at -48.8°C and boiling at 242°C. Propylene carbonate has a vapor pressure of 0.13 mmHg at 20°C, and 0.98 mmHg at 50°C.
Propylene carbonate is sold by chemical suppliers or can sometimes be found on eBay.
PC can be prepared from 1,2-propylene glycol and urea with a metal carbonate catalyst. Described here: 
- PC can be used for the electrodeposition of the alkali metals at STP as seen here.
Propylene glycol has little toxicity.
Propylene carbonate can be stored in closed bottles, away from moisture to prevent contamination.
As propylene carbonate has low toxicity, it can be safely poured down the drain.
