摘要: 本文研究了对甲基苯乙酸苄基酯(BCO2A)及苯乙酸1-萘基酯(ACO2N)在ZSM-5沸石中的光化学反应。研究发现,光解BCO2A在ZSM-5沸石中主要生成BA,而光解ACO2N只生成AA及NN.两种酯的产物分布和在乙腈溶液中的光解完全不同。这些结果是由ZSM-5沸石孔腔对底物分子的尺寸及形状具有选择性而引起的。

关键词: 芳甲基酯, 沸石, 尺寸/形状选择性

Abstract: Selectivity in organic photo chemical reactions continues to be one of the main topics of current interest[1].For the various approaches,the use of constrained and ordered media has shown considerable promise [2].Here we illustrate that one can include organic molecules into ZSM-5 zeolite to control the pathways of their photochemical reactions.

Key words: arylmethyl esters, zeolite, size/shape selectivity
