苯基二氯化膦-苯二元体系汽液平衡数据的测定及关联

The Measurement and Correlation of Vapor-Liquid Equilibrium Data for the Binary System of Dichlorophenylphosphine-Benzene

在101.325 kPa下测定了苯基二氯化膦-苯二元体系不同液相组成的沸点,并对数据进行了关联。用Herington面积法对实验数据进行了热力学一致性检验。由实验数据推算出两端的无限稀释活度系数,回归得到Wilson方程配偶参数,并推算出了该体系的等温汽液平衡数据。该工作为苯基二氯化膦的分离提纯设计提供了较好的VLE数据和理论依据。

The vapor-liquid equilibrium （VLE） data of dichlorophenylphosphine-benzene system at 101. 325 kPa were measured and correlated. The thermodynamic consistency of the experimental data was checked by the Herington area test method. The experimental data were used to calculate the infinite dilution activity coefficient. Wilson equation was used as regression equation to obtain the Wilson parameters with which the isothermal vapor-liquid equilibrium data were deduced, This work provides useful VLE data and chemical engineering foundation for the separation and purification design of dichlorophenylphosphine.
