摘要：
The kinetics and mechanism of oxidation of sulfanilic acid by N-chloro-p-toluene sulfonamide (chloramine-T) have been studied in acid medium. The species of chloramine-T were analysed on the basis of experimental observations and predominantly reactive species was taken into account for proposition of most plausible reaction mechanism. The derived rate law (1) conforms to such a mechanism. - d[CAT]/dt = kK(1)[RNHCl][SA]/K-1 + [H+] (1) All kinetic parameters were evaluated. Activation parameters such as energy and entropy of activation were calculated to be (61.67 +/- 0.47) kJ mol(-1) and (-62.71 +/- 2.48) JK(-1)mol(-1) respectively employing Eyring equation.
