KINETICS AND MECHANISM OF THE OXIDATION OF SOME THIOACIDS BY QUINALDINIUM CHLOROCHROMATE
Abstract
The oxidation of thioglycollic, thiolactic and thiomalic acids by quinaldinium chlorochromate (QnCC) in dimethylsulphoxide (DMSO) leads to the formation of corresponding disulphide. The reaction is rst order each in QnCC. Michaelies-Menten type of kinetics is observed with respect to the thioacids. Reaction failed to induce the polymerisation of acrylonitrile. The reaction is catalysed by the hydrogen ions. The hydrogen ion dependence has the form: kobs = a + b [H+]. A suitable mechanism and rate law will be derived
