The kinetics of oxidation of α-amino acids (AAs) by chloramine-T (CAT) using β-cyclodextrin (BCD) as catalyst was studied in aqueous sodium hydroxide medium at 313K. The kinetics of reactions was fractional-order with respect to amino acids and β-cyclodextrin. First-order with respect to chloramine-T and inverse fractional-order with respect to OH− have been found. Effect of ionic strength, added salt and reaction product (PTS) had no effect on reaction rate. The dependence of the reaction rate on temperature was studied and activation parameters were computed from Arrhenius–Eyring plots. The reaction mechanism and the derived rate law are consistent with the observed experimental results.
