Description and Uses
Diethyl oxalate is used to prepare active pharmaceutical ingredients (API), plastics and dyestuff intermediates. It is also used as a solvent for cellulose esters, ethers, resins, perfumes and lacquers for electronics. It is involved in the transesterification reaction with phenol to get dipheny oxalate. It is also involved in the Claisen condensation ketosteroids to prepare glyoxalyl derivatives. Further, it is used to prepare sym-1,4-diphenyl-1,4-dihydro-1,2,4,5-polytetrazine. In addition to this, it is utilized in the microemulsion synthesis of zinc oxide nanoparticles.
