提出了一种不依赖组成分析测定汽液平衡的新方法,阐述了该方法的基本原理,给出了适合该方法的新型测定仪器,并应用该方法测定了乙醇-丙酮和环己烷-甲醇两个体系的常压汽液平衡数据,实测值与文献值吻合良好。
A new method that does not rely on the composition analysis to determine vapor-liquid equilibrium is proposed. The basic principle of this method is expounded. A new measuring instrument suitable for this method is given. The proposed method is applied to the determination of ethanol-acetone and cyclohexane-methanol The two systems of atmospheric vapor-liquid equilibrium data, the measured values and the literature values in good agreement.
