The rate law for oxidation of 2-propanol by chromic acid in aqueous acetone solutions has been found to be V = k3 [Cr(VI)| [2-propanol]ho, with the magnitude of k3 being over 700 times as great in 93.3% acetone as it is in water. In other respects (primary deuterium isotope effect, Hammett "rho" value, and salt effects) the general features of the reaction strongly resemble those observed in aqueous acetic acid solutions.

The kinetics of chromic acid oxidation of propanaldehyde, butyraldehyde and isobutyraldehyde in aq. acetic acid have been studied. The product of the oxidation is the corresponding carboxylic acid. The reaction is of first order with respect to each the acid chromate ion, HCrO4⊖, and the aldehyde but of second order to hydrogen ion. The rate increases with proportion of acetic acid in the solution. The activation parameters for the oxidation and enolisation reactions have been evaluated. The rate of enolisation under similar condition is less than that of oxidation. A mechanism in which the first step is the rapid reversible formation of a chromate ester followed by a hydrideion transfer in the rate determining step has been suggested.
