Chemistry & industry
Applications
UsesDiethyl carbonate (DEC) is generally used in the C-alkoxycarbonylation of enolate anions, aryl and alkyl cyanides. It reacts with 1,2-amino alcohols to yield corresponding 2-oxazolidinones. Additionally, DEC is also used as a component of electrolyte solution in lithium ion batteries.
General DescriptionDiethyl carbonate appears as a colorless liquid with a mild pleasant odor. It is slightly less dense than water and insoluble in water.
Preparation methods
PreparationDiethyl carbonate is prepared by reaction of phosgene and ethyl alcohol to produce ethyl chlorocarbonate followed by reaction with anhydrous ethylalcohol at elevated temperatures. direct synthesis of diethyl carbonate (dec) by carboxylation of ethanol with co2 was investigated over ceria catalysts.
