Redox Reactions of Cobalt (III) Complexes of α –Hydroxy Acids by Pyridinium Bromo Chromate in the presence of Surfactants

Abstract

The Kinetics of one electron transfer route seems to be un available for Pyridinium bromo chromate with cobalt (III) bound and unbound complexes of α –hydroxy acids in micellar medium pyridinium bromo chromate oxidises cobalt (III) bound and unbound α –hydroxy acids. It rules out the synchronous C-C bond fission and electron transfer to Cobalt (III) centre. Oxidation of above complexes increases with increase of temperature with increase in micellar concentration. An increase in the rate is observed. The added dimethyl dioctadecyl ammonium chloride (DDAC) increases the rate of oxidation of a reaction much more than Ammonium lauryl sulphate (ALS). Similar trends observed in Lactato and Glycolato Cobalt (III) Complexes
