Kinetics of Oxidation of Cyclohexanol by Ceric Ammonium Nitrate in Aq. HNO3

  • D. L. Mathur and G. V. Bakore

The oxidation of cyclohexanol by ceric ion has been studied in the presence of nitric acid (~1-2.5 M). The rate dependence on alcohol suggests intermediate complex formation. The increase in hydrogen ion and nitrate ion concentrations retards the rate of oxidation. The results have been explained on the basis of Ce (OH)3⊕, as the reactive species. The value of Kh for the equilibrium Ce4⊕ +H2O ⇄ Ce (OH)3⊕+H has been evaluated as 4.8 at 25°C in nitric acid medium. A mechanism based on decomposition of Ce (IV) -alcohol complex and rupture of α-carbon hydrogen bond in the rate determining step has been put forward.
