General description

Diethyl carbonate is an dialkylcarbonate. The synthesis of diethyl carbonate (DEC) from urea and ethanol has been investigated.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product is used as a greener reagent. Click here for more information.

Application

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.

Dialkylcarbonates are viewed as low-cost, low-toxicity reagents, finding application in many areas of green chemistry. Homogeneous alkoxycarbonylation of cellulose was accomplished by applying dialkycarbonates (dimethyl and diethyl carbonate) in the ionic liquid-electrolyte trioctylphosphonium acetate ([P8881 ][OAc])/DMSO or 1-ethyl-3-methylimidazolium acetate ([emim][OAc]).
