Abstract
Liquid-liquid phase equilibrium for two binary systems: 1-propoxy-2-propanol. +. water and 1-(1-methyl-2-propoxyethoxy)2-propanol. +. water ranging from their lower critical solution temperatures to 328.15. K under atmospheric pressure were performed by using the phase volume method. The experimental data were further correlated with the UNIQUAC model by fitting the UNIQUAC interaction parameters as a function of temperature. The critical mass fraction and the lower critical solution temperature were determined by fitting the experimental data to the critical scaling law. © 2013 Taiwan Institute of Chemical Engineers.
