Abstract

The kinetics of oxidation of cinnamaldehyde by Cr(VI) in 90% (v/v) aqueous acetic acid has been studied. The reaction follows second-order kinetics, first-order each in cinnamaldehyde and Cr(VI), at constant ionic strength and [H+]. A mechanism involving the chromic acid ester of hydrated cinnamaldehyde as intermediate has been suggested.
