Diethyl carbonate is a carbonate ester of carbonic acid and ethanol with the formula OC(OCH2CH3)2. At room temperature (25 °C) diethyl carbonate is a clear liquid with a low flash point.
Diethyl carbonate is used as a solvent such as in erythromycin intramuscular injections. It can be used as a component of electrolytes in lithium batteries.
It can be made by reacting phosgene with ethanol, producing hydrogen chloride as a byproduct. This reaction is the base of why ethanol is added to chloroform in a 1% quantity by mass.
:2CH3CH2OH + COCl2 → OC(OCH2CH3)2 + 2HCl
