Wet oxidation of benzoic acid catalyzed by cupric ions: Key parameters affecting induction period and conversion

▶ An induction period occurs implying organic radical mechanisms. ▶ The statistical analysis points to the reaction temperature being the most decisive factor of catalytic wet oxidation. ▶ Oxygen partial pressure, initial substrate concentration and their interaction may also influence induction period. ▶ Oxidation proceeds through the hydroxylation of the aromatic ring.
