用NH3-TPD和d3-乙腈吸附的FT-IR表征了Pd/ZSM-5催化剂的酸性。研究了丙酮一步法合成甲基异丁基酮过程中Pd负载量对催化剂活性和产物分布的影响。结果表明，酸性中心和金属中心之间的适当平衡是获得高催化性能的必要条件。
The acidic properties of Pd/ZSM-5 catalysts were characterized by NH3-TPD and FT-IR of d3-acetonitrile adsorption. Effect of Pd loading on the catalytic activity and product distribution was studied in the one-step synthesis of methyl isobutyl ketone from acetone. The results indicated that a proper balance between acidic and metallic sites was necessary to obtain high catalytic performance.
