Isobaric Vapor-Liquid Equilibria for (Acetic Acid + Cyclohexane) and (Cyclohexane + Acetylacetone) at a Pressure of 101.3 kPa and for (Acetic Acid + Acetylacetone) at a Pressure of 60.0 kPa
Isobaric vapor-liquid equilibrium (VLE) data for (acetic acid + cyclohexane) and (cyclohexane + acetylacetone) were determined at a pressure of 101.3 kPa and those for (acetic acid + acetylacetone) at a pressure of 60.0 kPa. A minimum boiling azeotrope was found for (acetic acid + cyclohexane). The nonideality of the vapor phase of (acetic acid + acetylacetone) and (acetic acid + cyclohexane) was investigated by using the Hayden-O Connell equation. Thermodynamic consistency was tested for all of the VLE data. The experimental data were correlated satisfactorily by the Wilson, NRTL, and UNIQUAC models. Correlation results were in good agreement with experimental data.
