| Abstract: | The kinetics of phenol hydroxylation over copper hydroxyphosphate in the presence of hydrogen peroxide as an oxidant was studied systematically. The influences of the amount of catalyst, the concentration of hydrogen peroxide and phenol, as well as the temperature were investigated. The reaction orders of the reactants and catalyst were obtained by using initial reaction rates method being first order with respect to the amount of catalyst and the concentrations of phenol and hydrogen peroxide. Also, the apparent activation energy was calculated to be 12 kJ/mol. |
