What is the role of diethyl oxalate (DEO) in various industrial applications?

Label:chem

Topic
Diethyl oxalate (DEO) is an important chemical raw material that is miscible with common organic solvents such as ethanol, ether, and ethyl acetate. It has been widely used in medicine, organic synthesis, paper making, and other fields.
Answer
DEO serves as an ethylating agent and an irreplaceable chemical intermediate for producing ethylene glycol. It can also undergo condensation reactions with fatty acid esters, amides, aniline compounds, or many heterocyclic compounds to produce various chemical products. Additionally, significant chemical products like oxalic acid and diethyl carbonate (DEC) can be synthesized through hydrolysis and decarbonylation reactions of DEO.
