Commodity:
Diethyl Oxalate

CAS No.:
95-92-1

Formula:
C6H10O4

Diethyl Oxalate Process:
Take coal and air as the raw material, get Oxygen by air separation. The Oxygen converts coal into syngas, then eparated the syngas into Carbon Monoxide, Carbon Dioxide and Hydrogen. Finally, use the Carbon Monoxide coupling to synthesize Diethyl Oxalate.
