Ethylene carbonate is the organic compound with the formula (CH2O)2CO. It is classified as the carbonate ester of ethylene glycol and carbonic acid. At room temperature (25 °C) ethylene carbonate is a transparent crystalline solid, practically odorless and colorless, and somewhat soluble in water. In the liquid state (m.p. 34-37 °C) it is a colorless odorless liquid.
Ethylene carbonate is produced by the reaction between ethylene oxide and carbon dioxide. The reaction is catalyzed by a variety of cations and complexes:
Ethylene carbonate (and propylene carbonate) may be converted to dimethyl carbonate (a useful solvent and a mild methylating agent) via transesterification by methanol:
Dimethyl carbonate may itself be similarly transesterified to diphenyl carbonate, a phosgene-substitute:
Ethylene carbonate is used as a polar solvent with a molecular dipole moment of 4.9 D, only 0.1 D lower than that of propylene carbonate. It can be used as a high permittivity component of electrolytes in lithium batteries.
Ethylene carbonate is also used as plasticizer, and as a precursor to vinylene carbonate, which is used in polymers and in organic synthesis.
