摘要：
The kinetics of the Ag(I)-catalysed peroxydisulphate oxidation of benzamide in 30% (v/v) MeCO2H:H2O at constant ionic strength have been studied. The rate at which peroxydisulphate disappears is proportional to the peroxydisulphate and Ag(I) ion concentrations, but independent of benzamide concentration. Allyl acetate, an effective radical scavenger for the sulphate radical ion, inhibits the reaction. The different thermodynamic parameters are evaluated. A free radical mechanism involving Ag(II) is proposed on the basis of products.
