摘要：

The kinetics of oxidation of cyclohexanone(chxn), 2‐butanone(but), and 1,3‐dihydroxy‐2‐propanone (dhp) have been investigated in aqueous acidic media. A first‐order dependence in complex is obtained at high acid and low oxidant concentration for these ketones. However, a zero‐order rate prevails at high oxidant and low acid concentration, and this rate has been shown to be the acid catalyzed enolization rate of the ketone. A general rate expression has been derived to explain these behaviors and plausible mechanism has been offered by assuming the enol as the reactive species. Copyright © 1990 John Wiley & Sons, Inc.
