Abstract
Isobaric vapor-liquid equilibrium (VLE) data for binary system of water + 2-azido-N,N-dimethylethanamine (DMAZ) was measured at 4 kPa. The results showed an azeotropic point at x1 = 0.985 and T = 302.17 K. The data was correlated with nonrandom two-liquid (NRTL), Wilson and universal quasi-chemical activity coefficient (UNIQUAC) models for the liquid phase. A comparison of the model performances was made using of the criterion of the average absolute deviation, standard deviation and mean standard deviation in boiling-point temperature. The results indicated that the NRTL activity coefficient model satisfactorily correlated the VLE data.
测定了水+ 2-叠氮- n, n -二甲基乙胺(DMAZ)二元体系在4 kPa下的等压汽液平衡(VLE)数据。结果表明，共沸点x1 = 0.985, T = 302.17 K。数据与液相的非随机双液(NRTL)、Wilson和通用准化学活度系数(UNIQUAC)模型相关。以沸点温度的平均绝对偏差、标准偏差和平均标准偏差为准则，对模型的性能进行了比较。结果表明，NRTL活度系数模型与VLE数据的相关性较好。
