The oxidation of 1- Phenylethanol has been studied spectrophotometrically to compare the polymer substrate supported reagent with a commercially available cross-linked polymeric reagent. The reagent supported on anion exchange resin was found to be more efficient in the oxidation reaction. The reagent is very easily separated from the reaction mixture and can be manually removed from the reaction mixture, which remains clear during and after the reaction. The kinetic of oxidation of 1-Phenylethanol with chromic acid supported on anion exchange resin like Dowex 22 [Cl-] in 1, 4-dioxane has been studied. The reaction is found to be of zero order each in concentration of alcohol and oxidant. The oxidation product have been isolated and characterized by its derivative, UV and FT-IR and C13 NMR spectral studies. The effect of substituent’s on the rate of oxidation and the activation parameters were determined with respect to slow step of mechanism.
