Product Applications
Diethyl Oxalate Supplier In India
Diethyl oxalate is especially used in the production of insecticides and also as a raw material for oxalate synthesis in many fields such as pharmaceutical industry (production of steroids, barbiturates), printing and dyeing industry (citric yellow dyes) and other specialty chemicals in PU and plastic industries.
Dimethyl oxalate is used as chelating agent in alkylation and cosmetic industries.
For countries with low oil content but large coal reserves (i.e., countries with great potential for syngas chemistry, e.g., China), oxidative carbonylation of methanol provides a promising approach for the important C2-based chemical glycols. [8] Dimethyl oxalate can be converted to ethylene glycol in high yield (94.7%) by hydrogenation under a copper-containing catalyst.

The generated methanol is recycled in the oxidative carbonylation process; therefore, the only raw materials consumed in the whole process are carbon monoxide, hydrogen and oxygen. Following the coal to ethylene glycol process, a 200,000-ton-per-year ethylene glycol plant has been built in Inner Mongolia, and a second 250,000-ton-per-year plant is planned for Henan in 2012. Other ethylene glycol plants with a total annual capacity of more than 1 million tons are being planned.

Furthermore, dimethyl carbonate can be obtained by decarbonation of dimethyl oxalate at around 100 °C in the presence of alkali metal alcohol salts, which are discussed as fuel additives from biomass (so-called oxygenated compounds).

The carbon monoxide formed can feed back into the reaction forming dimethyl oxalate.
Diphenyl oxalate is obtained by the ester exchange reaction of dimethyl oxalate with phenol in the presence of a titanium catalyst, which is decarbonized again to diphenyl carbonate in the liquid or gas phase. Diphenyl carbonate can be used as a substitute for the highly toxic phosgene used in the production of polycarbonate.
