speeds of sound and isentropic compressibilities of binary mixtures of 1 heptanol 1 2 dichloroethane 1 1 1 trichloroethane 1 1 2 2 tetrachloroethane trichloroethylene and tetrachloroethylene at 303 15 k comparison with theories
Physics and Chemistry of Liquids, 2007Co-Authors: H Iloukhani, B SamieyAbstract:Densities ρ, and speeds of sound u, of the binary mixtures of 1-Heptanol with 1,2-dichloroethane, 1,1,1-trichloroethane, 1,1,2,2-tetrachloroethane, trichloroethylene, and tetrachloroethylene have been measured over the complete composition range at 303.15 K. Isentropic compressibility κs, and Isentropic compressibility deviations Δκs were calculated, and were correlated by a Redlich–Kister type function to determine the fitting parameters and the SDs. The results are consistent with the self-association of 1-Heptanol and the polar and nonpolar characters of used chloroethanes or chloroethylenes, which produce the dissociation of 1-Heptanol. Speeds of sound and isentropic compressibilities have been compared with calculated values from Jacobson free length theory, Schaaff collision factor theory, Nomoto relation, Junjie relation and Van Deal ideal mixing relation.

excess molar volumes viscosities and speeds of sound of the ternary mixture 1 heptanol 1 trichloroethylene 2 methylcyclohexane 3 at t 298 15 k
The Journal of Chemical Thermodynamics, 2007Co-Authors: H Iloukhani, B SamieyAbstract:Abstract Densities (ρ), viscosities (η), and speeds of sound (u) of the ternary mixture (1-Heptanol + trichloroethylene + methylcyclohexane) and the involved binary mixtures (1-Heptanol + trichloroethylene), (1-Heptanol + methylcyclohexane), and (trichloroethylene + methylcyclohexane) at 298.15 K were measured over the whole composition range. The data obtained are used to calculate excess molar volumes (VE), excess isobaric thermal expansivity (αE), viscosity deviations (Δη), excess Gibbs free energies of activation of viscous flow (ΔG∗E), and excess isentropic compressibilities ( κ S E ) of the binary and ternary mixtures. The data of the binary systems were fitted to the Redlich–Kister equation while the best correlation method for the ternary system was found using the Nagata equation. Viscosities, speeds of sound and isentropic compressibilities of the binary and ternary mixtures have been correlated by means of several empirical and semi-empirical equations. The best correlation method for viscosities of binary systems is found using the Iulan et al. equation and for the ternary system using the McAllister equation. The best correlation method for speeds of sound and isentropic compressibilities of the binary systems is found using the IMR and for the ternary system using the IMR and JR.

Journal of Chemical & Engineering Data, 2005Co-Authors: H Iloukhani, B SamieyAbstract:Densities (ρ) and viscosities (η) of the binary mixtures of 1-Heptanol with 1,2-dichloroethane, 1,1,1-trichloroethane, 1,1,2,2-tetrachloroethane, trichloroethylene, and tetrachloroethylene have been measured at (293.15, 298.15, and 303.15) K for the liquid region and at ambient pressure for the whole composition range. Excess molar volumes (V E), excess thermal expansivities (αE), and viscosity deviations (δη) were calculated and correlated by Redlich−Kister type function to determine the fitting parameters and the standard deviations. The results are consistent with the self-association of 1-Heptanol and the polar and nonpolar characters of used chloroethanes or chloroethylenes, which produce the dissociation of 1-Heptanol. The two-parameter Heric interaction model has also been used to correlate the kinematic viscosities of binary liquid mixtures with mole fractions.

liquid liquid equilibrium for water 5 hydroxymethylfurfural 1 pentanol 1 hexanol 1 heptanol systems at 298 15 k
The Journal of Chemical Thermodynamics, 2019Co-Authors: Kyriale V M Cavalcanti, Luz M Follegattiromero, Irede DalmolinAbstract:Abstract Liquid-liquid equilibrium (LLE) data for {water + 5-hydroxymethylfurfural (HMF) + 1-pentanol/1-hexanol/1-Heptanol} ternary systems was measured at 298.15 K and 0.1 MPa. The solute selectivity and the capacity of alcohols were evaluated and the results showed that 1-pentanol has better performance than 1-hexanol and 1-Heptanol for HMF recovery from aqueous solutions. The NRTL and UNIQUAC models were used to correlate the liquid-liquid experimental values and the binary interaction parameters obtained were thermodynamically consistent. The root-mean-square deviations (RMSD) between the experimental data measured and the calculated by the NRTL and UNIQUAC models were less than 0.69% for all systems.

densities speeds of sound and isentropic compressibilities for binary mixtures of 2 ethyl 1 hexanol with 1 pentanol 1 heptanol or 1 nonanol at the temperature 298 15 k
Journal of Chemical & Engineering Data, 2010Co-Authors: Edward Zorȩbski, Monika Geppertrybczynska, Beata MaciejAbstract:Densities and speeds of sound for binary mixtures of 2-ethyl-1-hexanol with 1-pentanol, 1-Heptanol, or 1-nonanol were measured over the entire composition range at the temperature 298.15 K by means of a vibrating tube densimeter and the pulse-echo-overlap method. Also, the densities for pure compounds in the temperature range from (288.15 to 318.15) K were measured. From experimental data, the excess molar volumes and excess molar isentropic compressibilities were calculated. The deviations of the speeds of sound were calculated as well. The Redlich−Kister polynomials were fitted to the results, and smooth representations of the results are presented. For the mixtures studied, the negative values of the excess molar isentropic compressibilities over the entire composition range are observed. The values of the excess molar volumes are negative over the entire composition range for mixtures of 2-ethyl-1-hexanol with 1-pentanol or 1-Heptanol. For the mixtures of 2-ethyl-1-hexanol with 1-nonanol, the excess m...
