摘要
试验测定了碳酸二甲酯-苯甲醇体系在常压下的汽液平衡数据,采用Herrington法对数据进行了热力学一致性检验,结果表明所测数据符合热力学一致性。同时依据测定的汽液平衡数据计算出碳酸二甲酯及苯甲醇的无限稀释活度系数,求出Wilson活度系数模型参数,并计算了该体系于413.15 K的汽液平衡数据。
Vapor-liquid equilibria (VLE) data of dimethyl carbonate (DMC) ( 1 )-benzyl alcohol (2) system at 101.33 kPa were measured. The thermodynamic consistency of the VLE data was examined by Herrington method. In the meantime, the infinite dilution activity coefficient of dimethyl carbonate and benzyl alcohol and the parameters of activity coefficient of Wilson model were determined with the experimental data. The isothermal vapor-liquid equilibria data at 413.15 K were predicted.
