Abstract

Sugars containing either aldehyde (aldose), ketone (ketose) or hemiacetal groups can be oxidized and are classified as reducing sugars. As oxidation of carbohydrates is widely studied under the field of organic chemistry, the present work deals with the study of the redox reactions between peroxodisulphate and xylose underuncatalyzed and catalyzed conditions. The kinetic study of the above reactions showed that these reactions followed first order with respect to peroxodisulphate and the silver nitrate ion catalyst and a fractional order of (0.2) with respect to xylose. Ag catalyst was used to increase the rate of reaction in case of xylose where reactions proceed very slowly with respect to time as compared to other sugars used. The oxidation showed that configuration of sugars has some bearing on rate of oxidation. At lower concentration of oxidants, the linear dependence of reaction rate tends towards new order at their higher concentration. The rate of reaction was affected at elevated temperature where thermodynamic activation parameters like activation energy (Ea), enthalpy change of activation (∆H#), free energy change of activation (∆G#) and entropy change of activation (∆S#) were determined by Arrhenius and Erying equations. The analysis of the reaction products using IR revealed the presence of formaldehyde and formic acid. A mechanism of the reactions was proposed to explain the experimentally observed rate law and the products.
