| 摘 要： | 采用软模板法制备出多孔碳材料，以此为载体采用浸渍法制备了Ru／C催化剂，用于硝基苯与苯甲醇“一锅法”合成N-亚苄基苯胺中。利用XRD、SEM、TEM等方法对催化剂进行了表征。考察了Ru负载量对催化剂催化性能的影响，并对反应条件进行了优化。结果表明，Ru负载量为5．0wt％时Ru／C催化剂具有最佳的催化活性和选择性。在实验优化条件下反应22h，硝基苯转化率为100％，N-亚苄基苯胺选择性可达94．1％。

| Abstract: | A series of Ru/C catalysts were prepared by impregnation method using the porous carbon materials as support which was prepared by soft template method. The catalysts were used in the one-pot synthesis of N-benzalaniline from nitrobenzene （NB） and benzyl alcohol. The catalysts were characterized by XRD, SEM and TEM. The effect of Ru loading on the catalytic performance of Ru/C was studied, and the reaction conditions were optimized. The results showed that the Ru/C catalyst with 5.0wt% Ru loading exhibited the highest catalytic performance. Under the optimal reaction conditions, the N-benzalaniline selectivity reached 94.1% with 100% conversation of nitrobenzene after reaction 22 h. |
