用溴代正己烷与N-甲基咪唑反应制备了溴化1-己基-3-甲基咪唑离子液体;对离子液体进行了红外光谱分析和结构表征.测定了离子液体[HMIM]Br在温度为283.15 K至313.15 K之间的电导率,将测得的电导率值σ对(T-273.15)进行拟合,得出拟合方程和相关系数,结果表明离子液体[HMIM]Br的电导率随温度的升高而增大,符合VTF经验方程.离子液体[HMIM]Br在水、乙醇、乙腈等溶剂中的紫外吸收光谱分析结果表明,溶剂的极性和酸碱性对离子液体[HMIM]Br的紫外吸收光谱均有影响.%In this paper, 1-hexyl-3-methylimidazolium bromide ionic liquids was synthesized by hexane bromide and N-methyl imidazole. The structure of ionic liquid was characterized by infrared spectrum. The conductivity at the temperature between 283.15 to 313.15 K of ionic liquid [HMIM]Br was measured. The measured conductivity σ fit on (T - 273. 15). the regression equation and correlation coefficient were obtained. The results show that the ionic liquid [ HMIM] Br conductivity increases with increasing temperature, and is consistent with VTF empirical equation. Analyse ionic liquid [HMIM]Br in water, ethanol, acetonitrile and other solvents in the UV absorption spectrum results show that the UV absorption spectrum of [HMIM]Br ionic liquid was affected by solvent polarity and pH.
