采用改进的Ｐａｒｔｔ釜测定了在０．１０１３ＭＰａ下，间二甲苯－水二元部分互溶体系的气液相平衡数据，经热力学一致性检验表明，测定数据是可靠的。用ＮＲＴＬ方程关联了该体系气液相平衡数据，计算结果与实验值吻合好。
The gas-liquid equilibrium data of the m-xylene-water binary partial miscible system at 0.1013MPa was measured with a modified Partt kettle. The thermodynamic consistency test showed that the measured data were reliable. The NRTL equation is used to correlate the gas-liquid equilibrium data of the system. The calculated results are in good agreement with the experimental data.
