摘要

面向离子液体应用于萃取精馏，讨论了离子液体体系汽液平衡测定的液相配制、气相分析方法，提出了改进的气相回流器和沸腾器结构。基本思路来源于韩世钧先生研究团队发展的汽液平衡测定的拟静态法和置换法，以及能够主动提供气化中心的沸腾器结构。提出了液相组成计算方法和误差估计，适用于含多个挥发性组分和多个非挥发性组分体系的任意组分。上述方法能够实测获得挥发性组分的活度系数，并避免较为繁琐的含离子液体液相的分析。通过连续配制测定，能够获得活度系数随组成的变化规律，并应用于萃取精馏溶剂性能的评价及筛选。

Abstract

With respect to the application of ionic liquids in extractive distillation

this paper deals with some details of a synthetic method for liquid phase composition

while the vapor phase sample is analyzed

for the measurement of vapor-liquid equilibrium for systems containing ionic liquids. Basic ideas were from the quasi-static method

the exchanging method

and a structure of boiler featuring the active supply of vaporization center

which were developed by the research group of Prof. Shijun Han. Modified structures were presented for the droplet circulation of vapor phase and the boiler. A calculational procedure was presented for the liquid phase composition for systems containing several volatile and non-volatile components. Estimation of uncertainties was also presented. The method proposed provides experimental results for activity coefficients of the volatile components without the need of the relatively complicated analysis of the liquid phase sample containing ionic liquids. Through a procedure of repeated synthesis

trend of activity coefficients can be obtained with the variation of the composition. The method can be used for evaluation and screening of solvents for extractive distillation.
