| الوصف: | When pairs of liquid chemical species are mixed, biphasic regions may appear in the system instead of a monophasic region. When these phases are in equilibrium, it tells you which system is in liquid-liquid equilibrium. This phenomenon has great relevance in the industrial environment and in unit operations, such as liquid-liquid extraction. In this work, the thermodynamic modeling of a ternary system composed of water + acetic acid + ethyl acetate was carried out at two temperatures, 10 and 30ºC. The thermodynamic consistency of the experimental data was verified from the correlations of Othmer-Tobias and Hand, obtaining a correlation coefficient greater than 0.99, showing good consistency. The solvent extraction capacity (ethyl acetate) to separate the solute (acetic acid) was evaluated from the distribution coefficient and the separation factor. Thermodynamic modeling was used to predict the liquid-liquid equilibrium from the Non-Random Two-Liquids (NRTL) models and the Universal Quasi-Chemical (UNIQUAC) method using the gamma-gamma approach to compare with the results obtained experimentally. The global mean deviations were 1.63% and 2.39 for the UNIQUAC and NRTL models respectively, thus showing that they are effective in predicting the liquid-liquid equilibrium. ; Cuando se mezclan pares de especies químicas líquidas, pueden aparecer regiones bifásicas en el sistema en lugar de una región monofásica. Cuando estas fases están en equilibrio, le dice qué sistema está en equilibrio líquido-líquido. Este fenómeno tiene gran relevancia en el entorno industrial y en operaciones unitarias, como la extracción líquido-líquido. En este trabajo se realizó el modelado termodinámico de un sistema ternario compuesto por agua + ácido acético + acetato de etilo a dos temperaturas, 10 y 30ºC. La consistencia termodinámica de los datos experimentales se verificó a partir de las correlaciones de Othmer-Tobias y Hand, obteniendo un coeficiente de correlación mayor a 0,99, mostrando buena consistencia.
