摘　　要：采用改良的分步加酸、乙醚-丙酮萃取的方法合成了5种Keggin型硅钼钒杂多酸,分别用红外光谱（IR）检测到700~1 100cm-1范围内的4个特征吸收峰,X射线衍射（XRD）表征了硅钼钒杂多酸的二级结构,通过热重分析（TG）确定了杂多酸中结晶水的数目.In this paper,five kinds of Keggin-type Si-Mo-V heteropolyacids have been synthesized in the modified method that gradually adding acid,extracted by acetone-ether.Four characteristic peak of Keggin-type in 700-1 100cm-1 have been observed by infrared ray.These condary structures of heteropolyacids have been characterized by XRD.The number of crystalliferous water in the products are determined by TG.
