摘要

本研究对文献中报道的季乙酸-乙醇-乙酸乙酯-水体系及其子系统的实验汽液平衡(VLE)数据进行了综述。利用Redlich-Kister检验和Gibbs-Duhem方程的直接积分验证了VLE数据的热力学一致性。为了进一步整合，VLE数据使用NRTL方程进行关联。此外，估计了等温-等压条件下多组分系统Gibbs-Duhem方程直接积分的可靠值。该积分可用于检验实验汽液平衡数据的热力学一致性。

Vapor-Liquid Equilibrium in the Acetic Acid-Ethanol-Ethyl Acetate-Water Quaternary System: Critical Literature Review and Thermodynamic Consistency of the Experimental Data

This study presents a critical review of the experimental vapor-liquid equilibrium (VLE) data for the quaternary acetic acid-ethanol-ethyl acetate-water system and its subsystems that are reported in the literature. The thermodynamic consistency of the VLE data were verified using two integral tests: the Redlich–Kister test and the direct integration of the Gibbs–Duhem equation. The VLE data were correlated using the NRTL equation for further integration. Additionally, the reliable value of the integral derived from the direct integration of the Gibbs–Duhem equation for multicomponent systems under isothermal-isobaric conditions was estimated. This integral can be used for testing the thermodynamic consistency of experimental VLE data.
