| 摘 要： | 以相同硅铝比的微孔沸石MCM-49 和MCM-56为硅铝源, 通过碱处理和十六烷基三甲基溴化铵模板剂, 合成了具有较强酸性的六方结构介孔分子筛材料MM-49和MM-56, 并采用XRD、红外光谱、氮气吸附-脱附等方法对其进行了结构表征, 采用NH3-TPD和IR-吡啶吸附方法对其进行了酸性表征. 实验结果表明, MM-56和MM-49具有明显强于常规介孔分子筛酸性的特点, 在苯酚与叔丁醇的烷基化反应中表现了良好的催化性质.

| Abstract: | With zeolites MCM-56 and MCM-49 as the sources of silicon and aluminum treated with a sodium hydroxide solution,cetyltrimethylammonium bromide(CTAB)as template,mesoporous aluminosilicates with hexagonal structure denoted as MM-56 and MM-49 were synthesized.The structures of MM-56 and MM-49 were characterized via XRD,FTIR and N2 adsorption-desorption techniques.The acidities of MM-56 and MM-49 were characterized via NH3-TPD and IR spectroscopy of pyridine adsorption.Compared with conventional mesoporous alum... |
