Abstract
A new set of revised parameters for NRTL activity coefficient model was correlated for the quaternary mixture of acetic acid + isoamyl alcohol + isoamyl acetate + water based on available scientific experimental vapor – liquid, liquid – liquid and vapor – liquid – liquid equilibrium data. The structure of residue curve maps for the non-reactive quaternary mixture presents four binary azeotropes and two ternary azeotropes. No reactive azeotropes were found for the reactive system. The new set of parameters for NRTL activity coefficient model is more consistent with experimental data than current models and their predictions are used to calculate a complete thermodynamic characterization for the reactive and nonreactive fluid phase equilibria. The results can be used in reactive distillation calculations such as process synthesis and conceptual design.
