| 摘 要： | 采用双循环式汽液平衡釜测定了正己烷碳酸二甲酯系统于101.325kPa下的汽液平衡数据,并用统计学方法对其进行了热力学一致性检验。该系统存在最低恒沸物:恒沸点65.73℃,正己烷摩尔分率x1=0.755。其数据用Wilson、NRTL和UNIQUAC方程进行了关联,关联结果表明具有很高的精度。

| Abstract: | Vapor-liquid equilibrium (VLE) data of n-hexane-DMC system at 101.325kPa has been measured with a modified Rost equilibrium still. This system has lower azeotropic point of 65.73℃ and the azeotropic composition of n-hexane x1 is 0.755. The experimental data were correlated with Wilson, NRTL and UNIQUAC equations and the results had good accuracy. |
