摘要：
The selection of salting agents for extractive distillation of ethanol-water system through analyzing the vapor-liquid equilibrium (VLE)data was studied. Firstly, the atmospheric VLE data of the ethanol-water system were measured, and the reliability of the vapor-liquid equilibrium apparatus was tested by comparing the measured VLE data with those reposed in the literature and by checking their thermodynamic consistency. Secondly, the atmospheric VLE data of the Ethanol-water system with agents were measured, and also the changes in relative volatility and the selectivity were checked, so that the optimum agent lithium chloride was then selected. Finally, the impact of the lithium chloride concentration on VLE data of Ethanol-water system was studied.
