Homogeneous Catalysis in the Oxidation of P-Chlorophenol in Supercritical Water

This work is an investigation of the kinetics of the uncatalyzed and homogeneously catalyzed oxidation of p-chlorophenol in water near the critical point. The temperatures and pressures studied range from 310$\sp\circ$C to 400$\sp\circ$C and 75 to 240 atm, respectively. The rate expression for the disappearance of chlorophenol appears to be first order in the organic at low concentrations and second order at high concentrations. It does not appear to be a function of the concentration of oxygen. Under the conditions studied, the same rate expression holds at subcritical and supercritical conditions, which suggests that the reaction proceeds by the same mechanism in the two regions.
