Abstract

The kinetics of the oxidation of thiols by dimethyl sulphoxide in the presence of water were investigated using headspace gas chromatography (HSGC). The rate constants for this reaction were determined and found to be considerably larger than those for oxidation in pure dimethyl sulphoxide. The applicability of HSGC to studies of reaction kinetics was examined. It was established that HSGC can be employed for the determination of rate constants provided that the rate of the equilibration process is high compared with the reaction rate. The relative standard deviations indicate that the precision of the determination of rate constants by HSGC is good.
