| 摘 要： | 在大量实验数据的基础上,对丙烯腈-乙腈-水三元体系汽液平衡组成之间的规律性进行了研究。采用多参数Wilson方程进行关联,对该非理想性很大而且液相分层的三元体系能获得极为满意的结果。该式所采用的参数都由相应的二元体系的参数提供。对99组汽液平衡的实验数据进行计算,汽相组成（分子分数）的平均绝对误差为0.0098。用同一关联式对此三元体系的液液平衡曲线的结点进行关联,亦获得了满意的结果。本文在关联式的基础上还作出了汽液平衡组成、沸点组成、不同含水量下相对挥发度等曲线图,可方便地用于设计计算中。

| Abstract: | The study of the relationship of vapor liquid equilibria in the acryloni-trile-acetonitrile-water ternary system is based on a large number of experimental data. The multiparameter Wilson equation is used to correlate the vapor-liquid equilibrium data.The parameters in above equation are wholly provided from corresponding binary systems. The total average absolute arithmatic deviation of 99 data points is only 0.0098 mol fraction. It must be pointed out that this result is considerable successful in such non-ideal and partially miscible ternary system. The conjugate points of liquid-liquid equilibria can be correlated by using the same relationship, and quite good results can also be obtained.
On the basis of this relationship, we plot a series of curves, such as the curves of vapor-liquid equilibrium compositions, the curves of normal boiling point of solutions, the relative volatilities of acrylonitrile to acetonitrile at different contents of water. These curves can be used easily and efficiently in design calculations. |
