Kinetics of glycine oxidation by <i>N</i>‐bromophthalimide in the presence of sodium dodecyl sulfate

Abstract

Abstract The kinetics of oxidation of glycine by N ‐bromophthalimide (NBP) were studied in the presence of an anionic surfactant, sodium dodecyl sulfate, in acidic medium at 308 K. The rate of reaction was found to have first‐order dependence on [NBP] and fractional‐order dependence on [glycine] and [H + ]. The addition of reduced product of the oxidant had no significant effect on the rate of reaction. Increasing [Hg(OAc) 2 ] and [Br − ] increased the rate of reaction, whereas a change in ionic strength (μ) of the medium had no effect on oxidation velocity. The rate of reaction decreased with a decrease in dielectric constant of the medium. HCN was identified as the main oxidation product of the reactions. The various activation parameters have been computed. A suitable mechanism consistent with the experimental findings has been proposed. The index of cooperativity and the micelle binding constant have been calculated.
