| Abstract: | The oxidation of tetrachlorohydroquinone in an aqueous solution at pH 7.40 is an autocatalytic reaction (signoid kinetic curves).
The interaction of the tetrachloro-1,4-semiquinone radical anion with dioxygen occurs with the rate constantk
2 equal to 9±3 L mol−1 s−1 (22–37°C). Superoxide dismutase does not affect the maximum rate of tetrachlorohydroquinone oxidation.
