The kinetics of chromic acid oxidation of glyoxal is reported. The reaction is first‐order in glyoxal and indicates a gradual change from a first‐order to a zero‐order dependence on acidity. The kinetic nature of this reaction has been studied and the rate law is consistent with a proposed mechanism as follows; rate = kK b , K[Cr +6 ][Gx][H + ]/(l+0.238[H + ]) at 25°C. The product analysis indicates that formic acid is the oxidation product under similar kinetic condition.
