| Abstract: | Liquid-liquid equilibrium(LLE)data for the quaternary-system water-isopropyl ether-phenol-hydroquinone were measured at 46℃.The results were used to estimate the interaction parameters between each of the four compounds for NRTL model.The estimated interaction parameters were successfully used to predict the equilibrium composition by NRTL model. |
