Trimethylene carbonate or 1,3-propylene carbonate is a 6-membered cyclic carbonate ester. It is a colourless solid that upon heating converts to the polytrimethyl carbonate. Such polymers are of interest for biomedical applications. An isomeric derivative is propylene carbonate, a colourless liquid that does not spontaneously polymerize.

Preparation

This compound may be prepared from 1,3-propanediol and ethyl chloroformate (a phosgene substitute), or from oxetane and carbon dioxide with an appropriate catalyst:[1]

HOC3H6OH + ClCO2C2H5 C3H6O2CO + C2H5OH + HCl
C3H6O + CO2 C3H6O2CO

This cyclic carbonate undergoes ring-opening polymerization to give poly(trimethylene carbonate), abbreviated PTC.[1] The polymer PTC is of commercial interest as a biodegradable polymer with biomedical applications.[2][3]
