DEC (Diethyl carbonate) 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, DEC (Diethyl carbonate) can also reduce emissions CO2 and other particulates.
DEC (Diethyl carbonate) can be made by reacting phosgene with ethanol, producing hydrogen chloride as a byproduct.
Because chloroform can react with oxygen to form phosgene, chloroform can be stabilized for storage by adding 1 part (by mass) of ethanol to 100 parts (by mass) of chloroform, so that any phosgene that forms is converted into diethyl carbonate.
DEC (Diethyl carbonate) 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.
Yet another method is from the reaction of ethyl nitrite and carbon monoxide, where the ethyl nitrite can be made from nitric oxide and ethanol.
This method requires a catalyst such as palladium.
DEC (Diethyl carbonate) can also be made by the alcoholysis of urea with ethanol.
