Diethyl carbonate may be used in the following studies:
• Synthesis of β-enamino esters.
• Synthesis of carbamates and unsymmetrical alkyl carbonates, via reaction with aliphatic amines or alcohols by using a hybrid organic-inorganic material prepared by anchoring TBD to MCM-41 silica.
• As solvent in ruthenium catalyzed direct functionalisation of arene C-H bonds by aryl halides.
• To compose the commercial liquid electrolyte for lithium ion batteries.
• Homogeneous alkoxycarbonylation of cellulose.

General description

Diethyl carbonate is an dialkylcarbonate. The synthesis of diethyl carbonate (DEC) from urea and ethanol has been investigated.
