Dimethyl oxalate has the following uses:
Ethylene glycol production: Ethylene glycol can be produced by catalytic hydrogenation of dimethyl oxalate, which is one of its most important uses. Ethylene glycol is an important organic chemical raw material, widely used in polyester fiber, polyester resin, antifreeze, lubricant and other fields.
Synthesis of other organic compounds: As an organic synthesis intermediate, it can be used to synthesize a variety of organic compounds, such as diphenyl oxalate, oxamide, etc. Diphenyl oxalate is an important raw material for the production of polycarbonate, oxalamide can be used in the production of medicine, pesticides and so on.
Spice industry: Used as a spice fixative in the spice industry, it can make the aroma of spices more stable, extend the retention time, and help to improve the quality and use effect of spices.
Lösungsmittel: can be used as an organic solvent, used to dissolve some organic compounds. In the paint, ink and other industries, it can be used as a solvent or co-solvent to help dissolve resins, pigments and other components, improve the performance of paint and ink, such as leveling, drying, etc.
Fuel additive: dimethyl oxalate can be used as a fuel additive, which can improve the combustion performance of fuel, improve the efficiency of fuel, and reduce the emission of pollutants.
Electronics industry: In the electronics industry, dimethyl oxalate can be used to prepare electronic chemicals, such as electronic grade ethylene glycol, etc. These products can be used in semiconductor manufacturing, electronic component cleaning and other fields.
