Glycol Oxalate. Also called UBE/UCC. A process for making ethylene glycol from carbon monoxide in three stages involving methyl nitrite and dimethyl oxalate: 4CH3OH + 4NO + O2 = 4CH3ONO + 2H2O; 2CH3ONO + 2CO = CH3OOC•COOCH3 + 2NO; CH3OOC•COOCH3 + 4H2= HOCH2•CH2OH + 2CH3OH. All the methanol and nitric oxide are recycled. The process was developed jointly by UBE and Union Carbide Corporation in 1983 and piloted by the latter company.
