Kinetics of the oxidation of isopropanol by aquavanadium(V) ions in aqueous perchlorate media

Abstract

The rate of slow oxidation of isopropanol by V^V_aq in aqueous perchlorate media increases with increasing acidity. No intermediate complexes are detected, and the oxidation is discussed in terms of the reactions of VO⁺₂ and its protonated species. The kinetic investigation shows that only VO⁺_2aq and V(OH)³⁺_2aq are involved, and the energy and entropy of activation are compared with those for the oxidation of isopropanol by other transition metal cations.
