Diethyl carbonate (sometimes abbreviated DEC) is an ester of carbonic acid and ethanol with the formula OC(OCH₂CH₃)₂. At room temperature (25 °C) diethyl carbonate is a colorless 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 has been proposed as a fuel additive to support cleaner diesel fuel combustion because its high boiling point might reduce blended fuels' volatility, minimizing vapor buildup in warm weather that can block fuel lines. As a fuel additive, it can reduce emissions such as volatile organic compounds, CO₂, and particulates.
