Oxidation study of 4–Methoxybenzyl Alcohol by Cr (VI) oxidants in partial aqueous medium– A Comparative study

Akshi Bansal, B. K. Dangarh

Abstract :

Oxidation of 4–Methoxybenzyl alcohol by different Cr (VI) oxidants [PDC and PCC] has been studied in acetic acid–H₂O medium in the presence of PTSA spectrophotometrically. The reactions are found first order with respect to both the oxidants, [H⁺], and [substrate].Michaelis–Menten type kinetics is observed. The reaction rate decreases with increasing volume percentage of acetic acid in reaction mixture. The reaction was studied at different temperature [298–318 K] and activation parameters were computed. The oxidation product was identified as Cr (III) and corresponding aldehyde. The oxidation rate order was found with respect to the oxidants are: PCC > PDC
