Abstract: A hybrid molecular material (［Bmim］3PMo12O40) was synthesized using 1butyl 3methyl imidazolium bromide ionic liquid(［Bmim］Br) and the Keggintype phosphomolybdic acid (H3PMo12O40) as raw materials. The obtained material was characterized by XRD, FTIR and UVVis. The results of XRD and FTIR indicated the existence of the cationic group of ［Bmim］Br and Kegginstructure polyanion ［PMo12O40］3- in the hybrid material. The UVVis showed there was strong intermolecular interactions between the organic cation and the Keggintype anion of ［Bmim］3PMo12O40. The catalytic performances of ［Bmim］3PMo12O40 in alkene epoxidation were investigated using cyclododecene as the substrate and H2O2 as the oxidant. 

摘要： 采用1 - 丁基 - 3 - 甲基咪唑溴离子液体( [ Bm i m] B r ) 和 K e g g i n型的磷钼酸( H3PMo 1 2O4 0) 为原料, 制备 了一种杂化材料( [ Bm i m] 3PMo 1 2O4 0) , 通过X - 射线衍射仪( XR D) 、 傅立叶变换红外光谱仪( F T - I R) 和紫外 - 可见漫反 射光谱( UV - V i s ) 对催化剂进行了表征。XR D和F T - I R的结果表明, 所合成的杂化的分子材料保留了[ Bm i m] B r的 有机阳离子基团和 K e g g i n型的[ PMo 1 2O4 0] 3- 杂多阴离子基团; UV 的结果表明, 在杂化分子材料[ Bm i m] 3PMo 1 2 O4 0中有机阳离子基团与 K e g g i n型的杂多阴离子基团间有较强的相互作用。以过氧化氢为氧化剂, 环十二烯作底 物, 考察了[ Bm i m] 3PMo 1 2O4 0催化烯烃环氧化反应性能。
