中文摘要:
      本文通过茚虫威中间体催化加氢合成反应用钯炭催化剂的性能对比,考察了钯炭催化剂的载体和载体预处理对催化剂性能的影响。实验结果表明:硝酸超声回流处理活性炭可以有效地去除活性炭中的杂质灰分,减小杂质对催化剂性能的影响;选择平均孔径大和比表面积高的活性炭为Pd/C催化剂载体可以获得较好的催化反应活性和选择性。
Carriers of Palladium on Carbon Applied in Synthesis of Indoxacarb Intermediate
英文关键词:Indoxacarb  hydrogenation  Pd/C catalyst  ultrasound reflux  selectivity
英文摘要:
      Comparing the catalysts’ performance of palladium on carbon applied in the catalytic hydrogenation synthesis of indoxacarb intermediate, the effects of the carriers of catalysts and pretreatment were investigated in this paper. The results showed that nitric acid reflux treatment with ultrasound can effectively remove the ash of activated carbon and reduce the impact of those impurities on properties of catalysts. And in the catalytic reaction of indoxacarb intermediate, the Pd/C catalyst on activated carbon with large average pore size and high specific surface area exhibited better catalytic reactivity and selectivity.
