Description
Summary:The kinetics of the liquid-phase catalytic oxidation of para -cresol with an ozone-air mixture in the presence of manganese(II) acetate is reported. In an acetic anhydride medium, para -cresol reacts with ozone as para -cresyl acetate, which is formed at the instant the solution to be oxidized is prepared. Under these conditions, the major oxidation products are para -acetoxybenzyl acetate (63.5%) and para -acetoxybenzylidene diacetate (13.7%). The effect of the managanese(II) acetate concentration on the traction selectivity with respect to the oxidation of the methyl group of the substrate is reported. A mechanism consistent with the experimental data available on this catalytic redox reaction is suggested.
