摘要
最近,多级孔沸石分子筛的合成受到了研究者的广泛关注~[1]。在这项工作中,我们报道通过离子交换的方法合成了含铁的多级孔ZSM-5沸石分子筛,获得的样品通过芳香化合物与卞基氯的烷基化反应评价了其催化性能,结果表明含铁的多级孔ZSM-5沸石分子筛在这些反应中展现了较优异的催化性能,暗示了这类催化剂在傅克烷基化反应中有着潜在的应用,尤其朝向大分子的催化反应。
Recently,the synthesis of hierarchical zeolites has recieved much attention.In this work,we report that iron-containing hierarchical ZSM-5 was prepared by ion-exchange method and its catalytic performance was evaluated by the benzylation of aromatics by benzyl chloride.This result indicated that iron-containing hierarchical ZSM-5 exhibited superior catalytic performance in these reactions,suggesting that such catalyst has potential applications in Friedel-Crafts alkylations,especially of large molecules.
