摘要
采用离子交换法合成了一系列杂多阴离子柱撑水滑石；用元素分析、ＸＲＤ、ＩＲ和ＤＴＡ等方法对柱撑产物的组成和结构进行了表征。在异丙醇反应和烷基化反应中考察了柱撑材料的催化性能，发现柱撑材料在异丙醇反应中同时表现出酸碱两种催化作用，在异丁烷与丁烯的烷基化反应中表现了较高的催化活性和Ｃ＿８选择性。
Hydrotalcite-like compounds pillared with heteropolyanions were synthesized by direct ion-exchange reactions and were characterized by elemental analysis,XRD,IR and DTA spectra.Thecatalytic properties of the pillared products were investigated with isopropanol conversion andalkylation reaction.The results show that the pillared products display simultaneously acid andbase catalysis over isopropanol conversion, and have higher activity and selectivity towards C_8 inthe alkylation of iso-butane with butene.
