Abstract

Abstract: Spectrophotometrically, the oxidation of sugarcane molasses using the sucrose unit (SCM) by a hexacyanoferrate(III) ion at a constant ionic strength of 1.0 mol dm –3 was studied. As the alkali content rose, the rates of reaction were observed to rise, suggesting that the reaction was base‐catalyzed in nature. The structure of the 1:1 intermediate complex proves the obedience of [SCM] reliance on rate constants for the Michaelis–Menten kinetics. After 65–70% of reaction completion, the discrepancy between first‐order pseudo‐curves and linearity ensures that a variety of oxidation products are intervened during the progression of the reaction. The redox system was carried out through the mechanism of free‐radical action. The activation parameters were measured, and an effective reaction mechanism has been developed and debated. Oxalic acid as a natural antioxidant compound was synthesized by the oxidation of SCM using the hexacyanoferrate(III) ion.
