Abstract

Kinetics and mechanism of oxidation of D-L methionine (Met) by sodium N-chlorotoluene-p-sulphanamide (CBT) in alkaline medium in presence of OsO4 catalyst have been investigated at 30 degrees C, and the results are compared to the reaction without Os(VIII) catalyst. The reaction rate shows a first order dependence each on CAT] and methionine] and inverse fractional order on OH-] and tractional order on OsO4]. Additions of halide ions and variation of ionic strength and dielectric constant of the medium do not have any significant effect on the reaction rate. Thermodynamic parameters have been evaluated.
