Measurement and Correlation of LiquidLiquid Equilibrium Data of Mesityl OxideWaterPhenol Ternary Systems
摘要
Abstract
Liquid-liquid equilibrium data are the basis for design and simulating calculation of chemical extraction processes. In order to provide fundamental data for phenol extraction processes from wastewater, experimental liquid-liquid equilibrium data were determined for the mesityl oxide-water-phenol ternary system at 25, 40 and 50℃ under atmospheric pressure, and the partition coefficient curves were drawn under different temperatures. Meanwhile, the experimental data were correlated with the NRTL activity coefficient model, and binary interaction parameters of the ternary systems were obtained. The predicted data calculated by the regressed parameters show that the experimental data can be successfully correlated with the NRTL model. The relative root mean square deviations (RMSD) and absolute mean deviations (AMD) between calculated and experimental values are both less than 1.5%.关键词
