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，结果具有热力学一致性。采用等温平衡法测定了５～７５℃下辛烷水二元体系以及１０～７５℃辛烷磷酸水三元体系的液液相平衡数据。
The vapor-liquid phase equilibrium data for the binary system of octane-water at 0.1013MPa were determined by an improved Partt still and proved reliable with thermodynamic consistency test. The liquid-liquid phase equilibrium data for the binary system of octane-water at 5～75℃ and the ternary system of octane-phosphoric acid-water at 10～75℃ were measured with equilibrium method.
