Abstract

Catalytic activity of a palladium catalyst with a porous carbon support was prepared and tested for benzophenone hydrogenation. The selectivity and yields toward the two possible reaction products (benzhydrol and diphenylmethane) can be directed by the applied solvent. It was found that in isopropanol, the prepared support was selective towards diphenylmethane with high conversion (99% selectivity and 99% benzophenone conversion on 323 K after 240 min). This selectivity might be explained by the presence of the incorporated structural nitrogens in the support.

摘要

制备了一种负载在多孔碳载体上的钯催化剂，并对其进行了苯甲酮加氢反应的催化活性测试。通过选择不同的溶剂，可以控制两种可能的反应产物（苯甲醇和二苯甲烷）的选择性和产率。研究发现，在异丙醇中，所制备的载体对二苯甲烷具有较高的选择性和转化率（在 323 K 下反应 240 分钟后，选择性为 99%，苯甲酮转化率为 99%）。这种选择性可能是由于载体中存在的掺入结构氮所致。
