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.

Manufacturing of multifunctional materials through blending is a promising route for improving performance of biopolymers including starch. Non-isocyanate polyurethanes (NIPUs) are an emerging group of green materials. Understanding the mechanism of interaction between starch and NIPU not only highlights underlying
