【摘要】 实验以后合成法制备介孔分子筛催化剂SBA-15-PO₃H₂。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-PO₃H₂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。更多还原

【Abstract】 SBA-15-PO₃H₂ 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 results show that the structure of SBA-15-PO3 H2 retains the mesoporous hexagonal structure of SBA- 15.It can be reused with high activity for esterification reactions.更多还原
