摘要：

Experiments carried out in an integral isothermal fixed-bed reactor revealed that the selectivities of some of the products of the catalytic oxidation of o-xylene (mainly o-tolualdehyde, phthalide and phthalic anhydride) were strongly influenced by the partial pressure of oxygen. A kinetic model which accounts for the dependence of the selectivities on the composition of the reaction mixture (partial pressure of oxygen and aromatic compounds) was developed and tested. The experimental observations and the predictions of the kinetic model are in excellent agreement.
