| 摘 要： | 通过气相ＴｉＣｌ４对多种分子筛进行处理，用Ｈ２Ｏ２对苯乙烯的氧化反应作探针反应，考察了所得分子筛的催化活性，发现用ＺＳＭ－５制备的催化剂的催化性能最好，得到苯乙烯的转化率可达～１２％生成苯乙醛和环氧苯乙烷的选择性可达～５５．９％，并用ＩＲ对用于ＴｉＣｌ４处理过的ＺＳＭ－５进行了表征，证实了钛原子进入ＺＳＭ－５沸石骨架，生成了钛硅分子筛。

| Abstract: | The oxidation of styrene by H 2O 2 on several molecular sieves treated by TiCl 4 gas have been studied. The catalyst propared from ZSM 5 had high activity with conversion of styrene being 12%, and selectivity of epoxide + phenylacetaldehyde being 55.9%. IR spectra cofirmed that Ti atom had been incorporated in the framework of ZSM 5 zeolite molecular sieves treated by TiCl 4 gas. |
