Kinetics and Mechanism of Micelle-Catalysed Oxidation of DL-Alanine and Glycine by Chloromine-T

The kinetics of oxidation of DL-alanine by chloramine-T(CAT) in the absence of any surfactant has been studied and compared with the kinetics parameters observed in the presence of anionic micelles of sodium dodecyl sulfate (SDS) and cationic micelles of cetyl pyridinium chloride (CPC). The observed rate law in respect of [alanine] and [oxidant] is given as:

-d[CAT]/dt = k^/[alanine][CAT]

Where k'is a complex function of hydrogen ion concentration as well as surfactant concentration. In the presence of CPC, the kinetic features of decarboxylation of DL-alanine are different from those observed in the case of glycine.
