Chemical Description |
Dimethyl oxalate is an organic compound with the formula (CH3O2C)2. |
Synthesis Reference(s) |
The Journal of Organic Chemistry, 24, p. 261, 1959 DOI: 10.1021/jo01084a633 |
Purification Methods |
Crystallise the ester repeatedly from EtOH. De-gas it under nitrogen at high vacuum and distil it. [Beilstein 2 IV 1847.] |
General Description |
Dimethyl oxalate undergoes Cu/SiO2 catalyzed hydrogenation to yield ethylene glycol. It undergoes selective gas-phase hydrogenation catalyzed by Ag/SiO2 to yield corresponding alcohol. |
