摘要 为获得离子液体与有机物物理性质的数据,常压下,293.15～353.15K温度范围内,分别测定了1-丁基-3-甲基咪唑四氟硼酸盐([bmim][BF4])、1-丁基-3-甲基咪唑六氟磷酸盐([bmim][PF6])2种咪唑类离子液体以及它们和N,N-二甲基甲酰胺(DMF)构成的2个二元体系的密度。利用实验数据计算了溶液的超额摩尔体积(VE),结果均为负值,表明离子液体与DMF之间存在离子-偶极作用和填隙效应。分别用一次线性方程和二次多项式方程关联出密度随温度和DMF浓度的变化关系,结果比较满意。 In order to obtain the data of the physical properties of ionic liquids and organic,the densities of two imidazolium-based ionic liquids,1-butyl-3-methylimidazole tetrafluoroborate([bmim][BF_4]) and 1-butyl-3-methylimidazolium hexafluorophosphate([bmim][PF_6]),and their binaries with N,N-dimethylformamide(DMF) at the temperature range from 293.15 K to 353.15 K in atmospheric pressure were determined,respectively.Excess molar volumes(VE) of solution have been obtained from these experimental data and they are negative.It has been interpreted in terms of ion-dipole interactions and structural factors of the ionic liquid and DMF.The temperature and the concentration of DMF dependency were correlated with the density value by using a linear equation and fifth-order polynomial.The correlations give satisfactory results.
