In this paper, we report a simple template-free synthetic method that produces amorphous, nanoporous aluminosilicate and highly selective catalyst for toluene alkylation. The structure and composition of the material and its corresponding control material are characterized by various techniques. The material shows excellent catalytic selectivity for alkylation of toluene by tert-butyl alcohol in temperatures between 50–150 °C under atmospheric pressure, producing exclusively 4-tert-butlytoluene (ca. 99%).

无模板合成用于甲苯烷基化的高选择性无定形硅铝酸盐催化剂

在本文中，我们报告了一种简单的无模板合成方法，该方法可生产无定形的纳米多孔硅铝酸盐和用于甲苯烷基化的高选择性催化剂。材料的结构和组成及其相应的控制材料通过各种技术来表征。该材料在大气压下于50–150°C的温度下，对叔丁醇对甲苯的烷基化反应具有出色的催化选择性，仅生成4-叔丁甲苯（约99％）。
