Kinetic and Mechanistic Study of Oxidation of Catechine

A comparative rate study on the oxidation of catechine by quinolinium chlorochromate has been carried out in aqueous solution using spectrophotometric technique. The reaction follows first order kinetics with respect to both [QCC] and [substrate]. The effect of various constraints like solvent effect, reactant effect, oxidant effect and salt effect is also studied. The oxidation is studied in seven organic solvents; the solvent effect has been analyzed by Kamlet and Swain, two different multiparametric equations. On the basis of above study, a mechanism for oxidation of catechine has been purposed.
