盐-混合溶剂体系气-液平衡研究具有重要的理论和实用意义。盐加到互溶双液系能改变组分间相对挥发度,提高蒸馏效率,分离恒沸物。达面方工作,Furter已作过详细综述。从盐-混合溶剂体系气-液平衡研究可以计算离子的溶剂化数,探索离子-溶剂和溶剂-溶剂之间的相互作用。因此,盐-混合溶剂体系气-液平衡的研究目前在国内外越来越受到人们的重视。本文研究盐饱和下的硫酸鲤-乙醇-水体系在高原大气压(530 Torr左右)下的汽-液平衡。改进的Rose釜测定体系的p-T-x-y数据。按照Jaques的假二元体系模型,使用Wilson,NRTL和修正的UNIQUAC方程关联实验数据。在计算过程中,使用一个能在计算机上顺利得到结果的计算方法。
Salt-mixed solvent gas-liquid equilibrium research has important theoretical and practical significance. The addition of salt to the miscible two-liquid system can change the relative volatility between the components, increase the distillation efficiency and separate the azeotropes. To work on the surface, Furter has made a detailed review. From the gas-liquid equilibrium study of the salt-mixed solvent system, the solvation numbers of ions can be calculated and the interaction between the ion-solvent and the solvent-solvent can be explored. Therefore, the research on gas-liquid equilibrium of salt-mixed solvent system is more and more popular in the world. In this paper, we studied the vapor-liquid equilibrium of the carp-ethanol-water system under salt saturation at plateau atmospheric pressure (around 530 Torr). Improved p-T-x-y data from Rose pot assay system. According to the Jaques pseudo-binary system model, Wilson, NRTL and modified UNIQUAC equations were used to correlate experimental data. In the calculation process, use a calculation method that can get the result on the computer smoothly.
