General description

Ethylene carbonate is a cyclic carbonate with high dielectric constant.[1]

Application

Applications of ethylene carbonate (EC):
  • EC can be an effective liquefying reagent for cellulose liquefaction.[2]
  • Dimethyl carbonate (DMC) can be synthesized via the transesterification of EC and methanol.[3]
  • EC can be a non-hazardous alternative to phosgene and isocyanates for the synthesis of polyurethanes.[4][5]
