摘要：
The liquid-liquid equilibrium for the system water + ethanol + reformate was studied over the temperatures of (288.15, 298.15, 308.15, and 318.15) K. A typical reformate containing 5 mass % cyclohexane, 35 mass % isooctane, and 60 mass % xylene was used in this study. The results of this study showed that the addition of ethanol to a reformate + water mixture results in an increased water solubility in the organic phase. Raising the temperature will increase the solubility of ethanol in the organic phase and decrease the solubility of ethanol in the aqueous phase. The experimental data have been correlated using UNIQUAC and NRTL equations with average RMSDs of 0.168 and 0.287, respectively. The experimental results were used to estimate the interaction parameters between water, ethanol, and reformate for the UNIQUAC and NRTL equations as a function of temperature.
