  2. Dimethyl oxalate - Wikipedia

    en.wikipedia.org/wiki/Dimethyl_oxalate

    Dimethyl oxalate can be converted into ethylene glycol in high yields (94.7%) [10] [11] The methanol formed is recycled in the process of oxidative carbonylation. [12] Other plants with a total annual capacity of more than 1 million tons of ethylene glycol per year are planned. Decarbonylation gives dimethyl carbonate. [13]

  3. Carbonylation - Wikipedia

    en.wikipedia.org/wiki/Carbonylation

    Dimethyl carbonate and dimethyl oxalate are produced industrially using carbon monoxide and an oxidant, in effect as a source of CO 2+. [2]+ + + The oxidative carbonylation of methanol is catalyzed by copper(I) salts, which form transient carbonyl complexes.

  4. Oxalate - Wikipedia

    en.wikipedia.org/wiki/Oxalate

    Oxalate (systematic IUPAC name: ethanedioate) is an anion with the chemical formula C 2 O 2− 4. This dianion is colorless. It occurs naturally, including in some foods. It forms a variety of salts, for example sodium oxalate (Na 2 C 2 O 4), and several esters such as dimethyl oxalate ((CH 3) 2 C 2 O 4). It is a conjugate base of oxalic acid.

  5. Oxalic acid - Wikipedia

    en.wikipedia.org/wiki/Oxalic_acid

    Another process uses oxygen to regenerate the nitric acid, using a variety of precursors including glycolic acid and ethylene glycol. [17] As of 2011, this process was only used by Mitsubishi in Japan. [18] A newer method entails oxidative carbonylation of alcohols to give the diesters of oxalic acid: 4 ROH + 4 CO + O 2 → 2 (CO 2 R) 2 + 2 H 2 O

  6. Oxalyl chloride - Wikipedia

    en.wikipedia.org/wiki/Oxalyl_chloride

    Oxalyl chloride reacts with water giving off gaseous products only: hydrogen chloride (HCl), carbon dioxide (CO 2), and carbon monoxide (CO). (COCl) 2 + H 2 O → 2 HCl + CO 2 + CO In this, it is quite different from other acyl chlorides which hydrolyze with formation of hydrogen chloride and the original carboxylic acid.

  7. Ethylene glycol - Wikipedia

    en.wikipedia.org/wiki/Ethylene_glycol

    The oxidative carbonylation of methanol to dimethyl oxalate provides a promising approach to the production of C 1-based ethylene glycol. [11] Dimethyl oxalate can be converted into ethylene glycol in high yields (94.7%) [12] by hydrogenation with a copper catalyst: [13]

  9. o-Phenylenediamine - Wikipedia

    en.wikipedia.org/wiki/O-Phenylenediamine

    Quinoxalinedione may be prepared by condensation of o-phenylenediamine with dimethyl oxalate. Mercaptoimidazole are commonly used as antioxidants in rubber production, obtained by condensing xanthate esters. Condensation of substituted o-phenylenediamine with diketones yields various pharmaceuticals. [9] OPD is a ligand in coordination chemistry.
