Thermodynamic Properties on Mixing for Hexane + Cyclohexane + 1-Octanol at 298.15 K

Density, speed of sound, isentropic compressibility, and refractive index have been measured for the ternary mixture hexane + cyclohexane + 1-octanol at 298.15 K and at atmospheric pressure. From these data, excess molar volumes and excess isentropic compressibilities have been calculated. The resul...

Description
Summary:Density, speed of sound, isentropic compressibility, and refractive index have been measured for the ternary mixture hexane + cyclohexane + 1-octanol at 298.15 K and at atmospheric pressure. From these data, excess molar volumes and excess isentropic compressibilities have been calculated. The results were fitted by means of different polynomial expressions. Several empirical methods for predicting ternary derived properties from binary data were tested. The Nitta−Chao group contribution model was applied to predict the excess molar volume for this mixture.
