Studies on Kinetics and Mechanism of the Oxidation of Cobalt (III) Bound and Unbound α-Hydroxy Acids by 4-(Dimethylamino) Pyridinium Chlorochromate

Kannan Pownsamy, Sarojini Gopalakrishnan and Bezuayehu Befekadu

A variety of Chromium(VI) complexes have been prepared and tested to be effective oxidants, 4-(dimethylamino)pyridinium chlorochromate is one of them. The kinetics of 4-(dimethylamino) pyridinium chlorochromate (DMAPCC) oxidation reaction with cobalt (III) bound and unbound α-hydroxy acids have been studied in 0.10 mol dm−3 HClO4 at 30 ± 0.2ºC. From the kinetic and stoichiometric results with product analyses a suitable mechanism has been proposed.
