Studies in kinetics and mechanism of oxidation of d-glucose and d-fructose by alkaline solution of potassium iodate in the presence of Ru(III) as homogeneous catalyst
Kinetics of oxidation of d-glucose (glc) and d-fructose (fru) by potassium iodate has been studied for the first time in alkaline medium using Ru(III) as homogeneous catalyst. The linear dependence of the reaction rate at lower [IO3-] and [OH-] tends towards zero-order at their higher concentrations. Experimental results also show that the order with respect to [Ru(III)] is unity and the order with respect to [reducing sugar] is zero in the oxidation of both glc and fru. Variation in [Cl-] and ionic strength (mu) of the medium does not affect the oxidation rate. The species, [RuCl2(H2O)2(OH)2]- and IO3-, were found to be the reactive species of Ru(III) chloride and potassium iodate in alkaline medium, respectively. The reactions have also been studied at four different temperatures and with the help of observed values of pseudo-first-order rate constant (k1), the entropy of activation and other activation parameters have been calculated. A common mechanism, where the rate determining step involves the interaction between reactive species of Ru(III) chloride and reactive species of potassium iodate resulting in the formation of an activated complex,{A figure is presented}has been proposed. The formation of activated complex is very well supported by the spectrophotometric evidence, observed kinetic data and also by the negative entropy of activation observed for the oxidation of both glc and fru. Arabinonic acid and formic acid were identified as the main oxidation products of the reactions.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of Cl3Ru, you can also check out more blogs about10049-08-8
