Summary

Oxidation of short-chain alcohols (MeOH and EtOH) by CrVI in concentrated aqueous HClO4 does not fit pseudo-first order rate equations, but results can be expressed in a two-exponential equation. A reaction mechanism based upon a chromate ester intermediate in equilibrium with the protonated alcohol and the chromic acid, suitable for a longer chain alcohol, does not account for kinetic results. A new mechanism is considered involving an intermediate reaction between chromic and perchloric acids.
