摘要
采用改进的Ｐａｒｔ釜测定了在０．１０１３ＭＰａ下，辛烷－水二元部分互溶体系的汽液相平衡数据，经热力学一致性检验表明，所测的数据是可靠的。采用等温法制定了５～７５℃范围内的液液相平衡数据。实验结果表明，辛烷在水中的溶解度仅为７．３×１０－５～７．５×１０－４，水在辛烷中的溶解度为３．８×１０－３～１．０×１０－１，该体系是互溶度极小的体系。
The vapour liquid phase equilibrium data for the partially miscible system of octane water at 0.1013MPa were determined by using an improved Partt equilibrium cell. The thermodynamic consistency test indicates that the experimental data are reliable. The liquid liquid phase equilibrium data for the partially miscible system of octance water at the temperature range of 5￣75℃ were measured by isothermal method. The results indicated that the solubility of octane in water is 7.3×10 -5 ～7.5×10 -4 , and the solubility of water in octane is 3.8×10 -3 ～1.0×10 -1 .
