Description

General description

Ethylene carbonate is a cyclic carbonate with high dielectric constant.

Application

Applications of ethylene carbonate (EC):

• EC can be an effective liquefying reagent for cellulose liquefaction.
• Dimethyl carbonate (DMC) can be synthesized via the transesterification of EC and methanol.
• EC can be a non-hazardous alternative to phosgene and isocyanates for the synthesis of polyurethanes.
