摘　　要：以稀散金属铟的氯化物InCl3为原料,采用两步合成法合成了功能催化材料———室温离子液体[Bmim]Cl/InCl3(氯化正丁基咪唑三氯化铟),收率达76%.用元素分析、IR、超导脉冲傅立叶变换核磁共振波谱对产物结构进行表征,测定了离子液体的电导率,并用乙腈红外探针法考察了其Lewis酸性,定性地获得了其Lewis酸性强度.结果表明,得到的产品为室温下呈液态的酸性离子液体[Bmim]Cl/InCl3,收率达76%.将[Bmim]Cl/InCl3应用于催化二苯甲酮的合成中,表现出良好的催化性能.In this article,the organic functionalized catalytic material [Bmim]Cl/InCl3 was synthesized based on rarely scattered metal chloride InCl3 ,through a typical two-step way.The yield of [Bmim]Cl/InCl3 is 76%,the products [Bmim]Cl and [Bmim]Cl/InCl3 are characterized NMR,IR and UV.The chemi-cal composition of the intermediary product was determined by elemental analysis.Inspecting the ionic liquid electric conductivity.The strength of Lewis acidity of ionic liquids has been studied by IR using acetonitrile as a probe molecule.The result indicated：the functionalized ionic liquid [Bmim]Cl/InCl3 was prepared successfully.The strength of acidity of acidic ionic liquids have been qualitatively investigated by using Lewis acidic ionic liquids as catalyst and applying for synthesis of Diphenylmethanone.The result showed that the product is iron liquid at room temperature and the yield is 76%.[Bmim]Cl/InCl3 has good catalytic activity at synthesis in Benzopohenone.
