WebMar 9, 2024 · The reaction of oxalic acid to glycolic acid follows the same mechanism as the reduction of glycolic acid to ethylene glycol. Effectively, the formation of ethylene glycol requires the reduction of both acid groups. The formation of acetic acid however proceeds via the hydrogenolysis of the H 2 C–O bond. WebFirstly, ethylene glycol will be oxidised to oxalic acid. But oxalic acid can still be oxidised. In fact, it is the concept of titration of oxalates with potassium permanganate ( KMnO A 4 ). Under acidic conditions, oxalic acid ( H A 2 C A 2 O A 4) will be oxidised to CO A 2 by KMnO A 4 as: 2 MnO A 4 A − + 5 C A 2 O A 4 A 2 − + 16 H A + 2 ...
