ＸＲＤ，ＩＲ，２９ＳｉＭＡＳＮＭＲ，ＵＶ－ＶＩＳ及ＸＰＳ能谱表征证实钛原子进入了钛－硅五元环沸石的骨架晶格位（不含铝）．ＴＧ－ＤＴＡ结果表明，钛原子进入沸石骨架导致沸石骨架的热稳定性提高，超过１４７３Ｋ．氯丙烯与Ｈ２Ｏ２（３０％）的环氧化反应结果表明钛－硅沸石具有优异的氧化性能，这也从另一个侧面证实了钛原子位于沸石骨架晶格位． The XRD, IR, 29SiMASNMR, UV-VIS and XPS spectra confirmed that titanium atoms entered the framework lattice sites of titanium-silicon five-membered ring zeolite (without aluminum). The TG-DTA results show that the thermal stability of the zeolite framework increases when the titanium atom enters the zeolite framework, exceeding 1473K. Epoxidation of allyl chloride with H2O2 (30%) showed that titanium-silicalite possesses excellent oxidation performance, which confirms from another aspect that the titanium atom is located at the zeolite framework.
