Is diethyl carbonate volatile?
Dimethyl carbonate (DMC) is an organic compound with the formula OC(OCH3)2. It is a colourless, flammable liquid. This compound has found use as a methylating agent and more recently as a solvent that is exempt from the restrictions placed on most volatile organic compounds (VOCs) in the US.
How is diethyl carbonate made?
Production. It can be made by reacting phosgene with ethanol, producing hydrogen chloride as a byproduct. It can also be synthesized directly from carbon dioxide and ethanol using various methods, and via oxidative carbonylation with carbon monoxide. Another method is transesterification from dimethyl carbonate.
What is the boiling point of diethyl carbonate?
