Dimethyl oxalate 553-90-2 DMO

Dimethyl oxalate has the chemical formula CH₃OOCCOOCH₃. Its melting point is 50–54 °C, boiling point is 163.5 °C, relative density is 1.148, and refractive index is 1.379. It is soluble in diethyl ether, benzene, and chloroform, and slightly soluble in water. It can undergo condensation reactions with certain ketones. Dimethyl oxalate is primarily used in organic synthesis, but it is also employed in the plasticizer, pharmaceutical, and pesticide industries. The gas-phase catalytic coupling of carbon monoxide to synthesize dimethyl oxalate, as part of the technology for producing ethylene glycol from synthesis gas, has become an important research topic in the fields of C1 chemistry and organic chemistry in China.
