| 摘要: 在钒基催化剂上考察了助剂铯、铜、铊的引入对制取对叔丁基苯甲醛的反应性能的影响,并用扫描电镜、ICP等技术对其进行了表征。实验结果表明添加助剂铯后,目的产物对叔丁基苯甲醛的选择性提高,而对叔丁基甲苯的转化率影响不大;添加铜后对反应活性和选择性提高都有利;添加铊后的催化剂反应性能更优于添加其它助剂,获得了转化率大于12mol%、选择性大于80mol%的好结果,该催化剂稳定运转365小时后催化性能保持不变,是一种很有工业应用前景的催化剂。 |

| Abstract: In this paper, the effect of different promoters on the vapor phase selective reaction of p-tert-butyl toluene to p-tert-butyl benzaldelyde has been studied.The catalytic properties of the V-Cs-Cu-Tl Catalyst are also tested.The SEM, ICP technology is applied in the study to investigate the surface composition of the catalysts.In the results it is found that the selectivity of p-tert-butyl benzaldelyde increases with the Cs adding but the conversion of p-tert-butyl toluene effects stightly.However the additive Cu is advantage to both the conversion and the selectivity.On V-Cs-Cu-Tl Catalyst the excellent result that conversion of p-tert-butyl toluene and the selectivity of p-tert-butyl benzaldelyde reach above 12mol% and 80mol% respectively is gained.After runing 365 hours, the catalyst still possesses good catalytic ability.So this research has achieved some novelty and originality. |
