碳基类型对Pd/C催化剂催化性能的影响
|
摘要
通过浸渍法制备不同碳基类型的Pd/C催化剂,以催化对茴香胺N-烷基化反应研究不同碳基类型的Pd/C催化剂催化性能,然后选用X射线衍射、扫描电镜、BET、ICP等技术表征了催化剂。研究发现碳纳米管为基底制备的Pd/C催化剂Pd负载量高,具有良好的比表面积,催化茴香胺N-烷基化反应转化率能够达到较理想的85.0%,且单甲基化合物含量可高达97.8%。
Different carbon-based Pd/C catalysts were prepared by impregnation method to study the catalytic performance of different carbon-based Pd/C catalysts for the N-alkylation of p-anisidine,then the catalysts were characterized by X-ray diffraction,scanning electron microscopy,BET,ICP. The results show that the Pd/C catalyst prepared from carbon nanotubes as substrate had a high Pd loading,a good specific surface area,an excellent 85. 0% conversion rate of the anisyl N-alkylation reaction,and a monomethyl compound content. Up to 97. 8%.
