Abstract

The purpose of this work is to examine the mechanism and kinetics of N-acetyl alanine oxidation by Chloramine-T (CAT) in a hydrochloric acid medium at temperatures between 30 and 50 degrees Celsius. First-order kinetic dependency on both the oxidant [CAT] and [H+] is indicated by the experimental results. On the other hand, there is zero-order dependence on the substrate reactant [S] and chloride ion [Cl-]. The reaction is barely impacted by the medium's ionic strength. The reaction between N-acetyl alanine and Chloramine-T shows a 1:1 stoichiometry in the acidic media. To find the activation parameters, the reaction was examined at five different temperatures, ranging from 30°C to 50°C. Spectroscopic analysis revealed that the ultimate oxidation product of N-acetyl Alanine was N-chloro acetyl Alanine.
