Application

Diethyl carbonate is a versatile organic compound primarily used for C-alkoxycarbonylation of enolate anions, and aryl and alkyl cyanides. Its unique properties allow it to react with 1,2-amino alcohols to form 2-oxazolidinones. Besides its application in synthetic chemistry, it serves as a crucial component in the electrolyte solutions for lithium-ion batteries, enhancing their performance. Furthermore, diethyl carbonate acts as a solvent for various cellulose ethers and nitrocellulose, and it plays a vital role in the manufacturing process of radio tubes, fixing rare earths to cathode elements, and the production of natural and synthetic resins. It is also employed in pharmaceuticals, including erythromycin intramuscular injections, and in the synthesis of compounds such as 3-ethyl-4-methyl-5-phenyl-3H-oxazol-2-one and phenobarbital.
