采用1-丁基-3-甲基咪唑溴离子液体([Bmim]Br)和 Keggin型的磷钼酸(H3 PMo12 O40)为原料，制备了一种杂化材料([Bmim]3 PMo12 O40)，通过 X-射线衍射仪(XRD)、傅立叶变换红外光谱仪(FT-IR)和紫外-可见漫反射光谱(UV-Vis)对催化剂进行了表征。XRD和 FT-IR的结果表明，所合成的杂化的分子材料保留了[Bmim]Br 的有机阳离子基团和Keggin型的[PMo12 O40]3-杂多阴离子基团；UV 的结果表明，在杂化分子材料[Bmim]3 PMo12 O40中有机阳离子基团与Keggin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[Bmim]3 PMo12 O40催化烯烃环氧化反应性能。

A hybrid molecular material ([Bmim]3 PMo12 O40 )was synthesized using 1-butyl 3-methyl imidazolium bromide ionic liquid([Bmim]Br)and the Keggin-type phosphomolybdic acid (H3 PMo12 O40 )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 [PMo12 O40 ]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 ]3 PMo12 O40 .The catalytic performances of [Bmim]3 PMo12 O40 in alkene epoxidation were investigated using cyclododecene as the substrate and H2 O2 as the oxidant.
