本文分别测定了苯基二氯化膦和苯基膦酰二氯的饱和蒸气压(其温度范围分别为349.26～426.06k和377.15～457.65k).采用安托因方程拟合了蒸气压数据并与文献值作了比较.测定了两种二元系在101.325kPa下的沸点一液相组成数据,基于实测数据,采用Wilson活度系数模型关联了模型参数,相互作用参数关联为温度的线性函数,在此基础上推算了上述两个二元系在极低压力(1333Pa)的汽液平衡.

The vapor pressure of phenylphosphorus dichloride and phenylphosphonic dichloride in the ranges of 349. 26 - 426.06K and 377.15 -457.65K, respectively, were measured by static method. The experimental vapor pressure were fitted to Antoine equation and compared with literature data. Boiling temperature-liquid composition (T-x) data at 101. 325 kPa of two binary systems, phenylphosphorus dichloride-phosphorus trichloride and phenylphosphonic dichloride -phosphorus oxychloride systems, were measured using a standard Swietoslawski type ebulliometer. The interaction parameters of Wilson activity coefficient model were regressed by using the experimental data. Linear temperature functions for the interaction parameters were obtained. Vapor-liquid equilibrium phase diagrams at 1333 Pa (10mmHg) for these binary mixtures were predicted.
