中文摘要：

为 water+2-propanol+1-butyl-3-methylimidazolium 氯化物的蒸汽液体平衡(VLE ) 数据([bmim ] Cl ) 被测量。完全的 T 的六个集合， x ， y 数据被报导，在哪个IL免费的基础上的 2-propanol 鼹鼠部分在 0.1 点独立被修理， 0.2 ， 0.4 ， 0.6 ， 0.8 ，并且近似 0.98 ，当 IL 集体部分从 0.1～0.8 被改变时，在 0.1 的间隔。non-random-two-liquid (NRTL ) 和电解质 non-random-two-liquid (eNRTL ) 方程被用来相关有令人满意的结果的试验性的数据。第三的 VLE 行为也被建模，参数由相关获得了二个数据集合， IL 免费的基础上的 2-propanol 的鼹鼠部分在是约 0.1 和 0.98。这样，数据的六个集合令人满意地被复制。与 eNRTL 模型一起，为温度的 root-mean-square 偏差是 0.82 K 和那因为蒸汽阶段鼹鼠部分是 0.0078。活动系数和不稳定的部件的相对轻快上的 IL 的影响图形地也被说明。

英文摘要：

Vapor-liquid equilibrium （VLE） data for water ＋ 2-propanol ＋ 1-butyl-3-methylimidazolium chloride （[bmim]Cl） were measured. Six sets of complete T, x, y data are reported, in which the 2-propanol mole fraction on IL-free basis is fixed separately at 0.1, 0.2, 0.4, 0.6, 0.8, and approximate 0.98, while the IL mass fraction is varied from 0.1 to 0.8, in an interval of 0.1. The non-random-two-liquid （NRTL） and electrolyte non-random-two-liquid （eNRTL） equations are used to correlate the experimental data with satisfactory results. The ternary VLE behavior is also modeled with the parameters obtained by correlating two data sets, in which the mole fraction of 2-propanol on IL-free basis is approximately 0.1 and 0.98. In this way, the six sets of data are reproduced satisfactorily. With the eNRTL model, the root-mean-square deviation for temperature is 0.82 K and that for vapor-phase mole fraction is 0.0078. The influences of IL on activity coefficients and relative volatility of the volatile components are also graphically illustrated.
