Excess Enthalpy Data in Some Binary Systems Containing Non Electrolyte Solution and Their Correlations at 298.15K

Abstract

Excess enthalpy data measured at 298.15K were collected from the literature. The data contains 48 binary systems (812 data points). The experimental data were correlated by Redlich-Kister equation. In this work the following thermodynamics models were also tested. Wilson, NRTL models: and their parameters were calculated. A modified NRTL with a composition-dependent (α₁₂) parameter was also proposed. The correlation of excess enthalpy data in the systems using this model provides good results.
