Excess Enthalpies for Binary Mixtures of the Reactive System Acetic Acid plus n-Butanol plus n-Butyl Acetate plus Water: Brief Data Review and Results at 313.15 K and Atmospheric Pressure

The data on molar excess enthalpies, H-m(E), for the binary mixtures acetic acid + n-butanol, acetic acid +n-butyl acetate and n-butanol +n-butyl acetate at 313.15 K and atmospheric pressure were obtained with use of the C80 isothermal mixing calorimeter (Setaram). The correlation of the data was carried out using the NRTL model and Redlich-Kister equation. A comparative analysis with the literature data on all available binary subsystems of the quaternary system was carried out. Other thermodynamic properties (C-p,m(E), S-m(E), ?S-mix(m), G(m)(E) and ?(mix)G(m)) of the binary systems were estimated using literature data and well-known formulas of classical thermodynamics.

Automated summary

The molar excess enthalpies (H-m(E)) for three binary mixtures (acetic acid + n-butanol, acetic acid + n-butyl acetate, and n-butanol + n-butyl acetate) at 313.15 K and atmospheric pressure were obtained using Setaram's C80 isothermal mixing calorimeter. The data was correlated using the NRTL model and Redlich-Kister equation. Comparative analysis was conducted with literature data on all available binary subsystems of the quaternary system. Other thermodynamic properties (C-p,m(E), S-m(E), ?S-mix(m), G(m)(E), and ?(mix)G(m)) were estimated using literature data and classical thermodynamics formulas.
