MANNOSE - PEROXYDISULFATE REACTION: QUALITATIVE PRODUCT ANALYSIS, SURFACE EFFECT AND EXPERIMENTAL KINETIC MEASUREMENTS

Peroxydisulfate (PDS) is a powerful oxidizing agent for reducing sugars. Throughout the redox interaction with the D(+)mannose molecule, the current work used the iodometric technique of measurement to track the unconsumed (PDS) at various time intervals. The existence of formaldehyde and formic acid in the qualitative test of the volatile redox reaction products suggests that the mannose molecule undergoes oxidative cleavage at its C-C bonds and the aldehydic and primary alcoholic groups. According to surface effect experiments, the redox reaction is characterized by chain reactions. Based on the results of the kinetics experiments, it was determined that the reaction rate is first order for [PDS] and fractional order for [Mannose] and that both respond more rapidly as the concentrations of these substances rise. Investigating the effect of temperature on the redox reaction under controlled experimental settings revealed that increasing the temperature resulted in a faster pace. The activation energy of the redox process was calculated to be 26.85 kcal/mole based on the oxidation rate measurements taken at different temperatures. Other activation functions, such as the frequency factor, the change in free energy, and the change in entropy, were also measured at different temperatures. A rate law was developed, and appropriate reaction pathways for the oxidation of D(+)mannose were proposed based on the collected experimental data...
