KINETICS OF OXIDATION OF D-ARABINOSE AND D-XYLOSE BY VANADIUM (V) IN THE PRESENCE OF MANGANESE II AS HOMOGENEOUS CATALYST

Kinetics of oxidation of D-arabinose and D-Xylose by acidic solution of Vanadium (V) ions in the presence of manganese (II) has been reported. First-order dependence of the reaction rate was observed on [sugars] and [H+] at low concentrations throughout the oxidation reaction and a zeroth-order depe...
