Correlation Studies of Cyclohexanone/(C₅–C₁₀) Alkan-1-ol Binary Mixtures: PC-SAFT Model and Free Volume Theory

Abstract

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 + 1pentanol, 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.

Dielectric, Volumetric, Refractometric, and Excess Properties of (Cycloalkanone + Pentanol Isomers) Systems at T = 298.15 K

“…A literature survey of volumetric properties of these systems reveals that only few mixtures at the experimental conditions of this study have been examined. Thus, the experimental density values for the (CPO or CHO + 1-pentanol) and (CHO + 2-pentanol) binary systems were compared graphically with the available literature density data. ,,, Comparisons between the observed and literature density values are shown graphically in Figure a–c. According to the uncertainty of both the experimental and literature data, the observed density values are in good agreement with the values found in the literature.…”

Heat and mass transfer in binary fluids containing alcohols with the Soret effect

“…For 1-octanol and 1-nonanol, the mass fraction purities were 99.6% and 99.7%, respectively. In the present study, density and viscosity of pure MCH were measured experimentally, but for pure alcohols were obtained from our previous papers [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23].…”

“…ρ is density, and ψ is a measure of concentrationinduced density gradient to the temperature-induced density gradient. The motivation of this work as a continuation of our research program [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] is to evaluate thermal and composition effects on molecular interactions in binary mixtures of alcohols and other functional groups.…”
