摘要：The kinetics of co - oxidation study of anils and oxalic acid by PCC in aqueous acetic acid had beenstudied under different experimental conditions. The order is one with respect to oxalic acid , anil , and PPC. The order is1.5 with respect to [ H+ ].The oxidation was found to increase with increase of perchloric oxalic acids. The rate of the reaction was increased by theaddition of NaClo4 .The protonated species of the oxidant is involved in the rate - determining step. The effect of various meta and para -substituted anils on the reaction rate had been studied at four different temperatures viz., 35 , 40 , 45 and 50 0 c and thethermodynamic parameters are also calculated. The analysis of rate constants of ortho substituents reveas that the localizedand delocalized effects are major components while steric effect place only the minor role.
