| 摘 要： | 实验以后合成法制备介孔分子筛催化剂SBA-15-PO_3H_2。讨论了焙烧温度和时间、搅拌时间、磷硅摩尔比等对催化剂性能的影响。其最佳合成条件为:焙烧温度为500℃,焙烧时间5 h,搅拌时间4 h,n(P):n(Si)=7:100。采用XRD、SEM/TEM分析介孔分子筛的结构和形貌,实验结果表明催化剂SBA-15-PO_3H_2保持了纯硅SBA-15二维六方介孔结构。该催化剂重复使用性能良好。

| Abstract: | SBA-15-PO_3H_2 is prepared using a post-synthetic method.The optimal synthesis conditions are found as follows:calcination temperature 500℃,calcination time 5 h,stirring time 4 h,and mole ratio of phosphorus and silicon 7:100.The product is characterized by XRD and SEM/TEM.The resuits show that the structure of SBA-15-PO_3H_2 retains the mesoporous hexagonal structure of SBA-15.It can be reused with high activity for esterification reactions. |
