摘要：
Oxidation of aromatic amines (substrate) by peroxomonosulphate (PMS) in phthalate buffers at various temperatures revealed first-order dependence on [PMS] as well as [Substrate]. Rate of oxidation was found to increase with an increase in pH as well as dielectric constant (D) of the medium. The most plausible mechanism involving PMS(-) and substrate in rate limiting step was proposed. Hammett's plot of log-rate constant versus sigma deviated from linearity. Deviations were explained due to ara resonance interaction energies. (C) 1995 John Wiley & Sons, Inc.
