| Abstract: | KBr3 oxidation of xylose, in presence of H2SO4, follows first order kinetics in KBrO3] and xylose], and second order in H2SO4]. The acid-catalyzed reaction gives aldonic acid as product. A mechanism consistent with temperature, solvent, higher acidity and salt effects has been proposed. Thermodynamic constants have been calculated.
