The oxidation reaction of 2-aminophenol with dioxygen to 2-amino-phenoxazin-3-one has been investigated in water using cobalt(II) phthalocyaninetetrasodiumsulfonate as catalyst. The oxidation reaction was followed by measuring dioxygen uptake. Cobalt(II) phthalocyaninetetrasodiumsulfonate has been found to enhance the rate of oxidation of 2-aminophenol to 2-amino-phenoxazin-3-one. The rate constants of oxidation reaction showed linear dependence on catalyst concentration and saturation kinetics in both 2-aminophenol concentration and dioxygen pressure. A mechanism has been suggested for the oxidation reaction.
