摘要
对不同廉价模板剂合成的Ｔｉ－ＺＳＭ－５分子筛的结构与性能进行了表征。ＸＲＤ、ＩＲ和ＳＥＭ分析表明，在四乙基溴化铵、１，６－己二胺、正丁胺、四丙基氢氧化铵４种模板剂体系中合成的Ｔｉ－ＺＳＭ－５分子筛，钛均进入了分子筛骨架。ＮＨ３－ＴＰＤ测定表明，Ｔｉ－ＺＳＭ－５分子筛只有Ｌ酸中心，且酸性弱。Ｔｉ－ＺＳＭ－５分子筛具有憎水性和良好的热稳定性。
The structure and properties of Ti ZSM 5 zeolites synthesized with different cheap materials were studied in detail.It has been indicated that Ti ZSM 5 zeolites can be successfully synthesized using TEABr,HDA,n BuNH 2 and TPAOH as templates,and Ti may also be incorporated into the zeolite framework.Ti ZSM 5 zeolite has only L acid with weak acidity and good heat stability. Ti ZSM 5 possesses hydrophobic characteristic.
