Correlation Studies of Cyclohexanone/(C-5-C-10) Alkan-1-ol Binary Mixtures: PC-SAFT Model and Free Volume Theory
In this article the behavior of cyclohexanone + 1-alkanol, namely, 1-pentanol, 1-hexanol, 1-heptanol, 1-octanol, 1-nonanol, and 1-decanol, binary mixtures through the density and viscosity measurements has been studied as a function of composition and within the temperature range of 293.15-323.15 K. The excess molar volume and viscosity deviations have been calculated and fitted by the Redlich-Kister polynomial equation. For binary mixtures of cyclohexanone + 1-pentanol, values of excess molar volume are negative and for other mixtures are positive. For all binary systems viscosity deviations are negative and increase with the alkyl chain-of-alcohol. The results provide information on the interactions among the molecules in the pure state as well as the binary liquid mixtures. The measured densities and viscosities have been applied to test the applicability of the PC-SAFT and free volume models.
