Substrate Inhibition: Oxidation of DSorbitol and DMannitol by Potassium Periodate in Alkaline Medium

Authors: Y. Lakshman Kumar, R. Venkata Nadh, P. S. Radhakrishnamurti

Abstract—In the oxidation of Dsorbitol and Dmannitol by potassium periodate in alkaline mediam, sub strate inhibition was observed with both the substrates, i.e., a decrease in the rate of the reaction was observed with an increase in the concentration of substrate. The substrate inhibition was attributed to the formation of stable complex between the substrate and periodate. The reactions were found to be first order in case of peri odate and a positive fractional order with hydroxide ions. Arrhenius parameters were calculated for the oxi dation of sorbitol and mannitol by potassium periodate in alkali media.
