| Abstract: | The kinetics of the direct hydroxylation of benzene to phenol was studied by means of ultraviolet spectroscopy.The hydrogen peroxide reactions of benzene to phenol with the Nd-Cr/Al2O3 catalyst was speculated,the mathematical model of the kinetic was established as well as explain the experimental results.The results showed that under the experimental conditions,the hydroxylation reaction of benzene,oxidant hydrogen peroxide and catalyst were first-ordered reaction.The activation energy of the reaction was evaluated to be 24.41 kJ/mol. |
