ABSTRACT
Liquid-liquid equilibria (LLE) for the ternary acetic acid + water + butyl acetate and acetic acid + water + 2-methyl propyl acetate systems were measured at 304.15 K, 332.15 K, and 366.15 K under atmospheric pressure. LLE phase diagrams with binodal curves and tie lines were obtained. The experimental data were used to estimate the LLE interaction parameters in the NRTL model.
