摘　　要：杂多化合物是由几种金属和非金属组成的含氧酸的多核配合物,由于杂多酸具有可以任意改变的分子组成和广阔的应用背景,因此被广泛应用于催化、电、光、磁功能材料以及药物化学等领域.采用分步加入原料进行酸化、乙醚-硫酸萃取法合成了3种Keggin型杂多酸,采用红外光谱(IR)、X射线衍射(XRD)以及热重(TG)等方法对其进行表征.确定杂多酸的基本骨架及其多级结构,测定多酸中结晶水的含量.Heteropoly compounds are oxacid polynuclear complexes that composed of several metals and nonmetals, due to the heteropoly acid has a molecular composition that can be changed arbitrarily and broad application background, therefore, it has been widely used in catalysis, electricity, light, magnetic functional materials and pharmaceutical chemistry. 3 kinds of Keggin type heteropoly acids were synthesized by stepwise addition of raw materials to acidification and ether sulfuric acid extraction, and carried out characterization to its Infrared spectroscopy （ IR ） , X ray diffraction （ XRD ） , thermogravimetry （ TG ） and other methods. The basic framework of heteropoly acid were determined by IR, XRD determined its multi-level structure, TG determined the content of crystalline water in polyacids.
