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.
