Densities, ρ , and viscosities, η , for ternary liquid mixtures of tetrahydrofuran (1) + 1-chlorobutane (2) + 1-butanol (3) have been measured as a function of composition at temperatures of 283.15, 298.15 and 313.15 K and atmospheric pressure over the full range of composition. From theses results excess molar volume, V E , viscosity deviations, Δ η , from mole fraction average, and excess free energies of activation of viscous flow, Δ G ∗E , have been calculated. Excess molar volume, viscosity deviations and excess free energies of activation of viscous flow were fitted to Cibulka, Singh and Nagata equations. The results are discussed in terms of the molecular interaction between the components of the mixtures. Excess molar volumes and deviations of the viscosities for this ternary system were predicted from binary contributions using geometrical solution models, Tsao–Smith, Jacob–Fitzner, Kholer, Rastogi and Radojkovic. Additionally, experimental results are compared with those obtained by applying group-contribution method proposed by Wu.

Viscosities of the ternary mixture (1-butanol+n-hexane+1-chlorobutane) and the binary mixture (n-hexane+1-chlorobutane) have been measured at 298.15 K and 313.15 K. Viscosity deviations and excess Gibbs energy of activation of viscous flow for the binary and ternary systems were fitted to Redlich–Kister's and Cibulka's equations. The `viscosity–thermodynamic' model (UNIMOD) has been used to correlate experimental data for the binary mixtures and to predict the viscosities for the ternary system. The Group-Contribution Thermodynamic–Viscosity model (GC-UNIMOD), and the group contribution method proposed by Wu have been used to predict the viscosity of the binary and ternary systems.

Densities of the liquid mixtures (n-hexane+1-chlorobutane) and (1-butanol+n-hexane+1-chlorobutane) have been measured by the vibrating tube technique at 298.15 K and 313.15 K. With these densities, excess molar volumes were calculated. An extended version of the so-called ERAS model has been used for describing VE of the complete ternary system at 298.15 K. Qualitatively the ERAS-model gives an adequate representation of this system, being similar the shapes of both the experimental and the predicted curves.

Excess molar volumes at 298.15 K and atmospheric pressure were measured for {x1 CH3CO2(CH2)3CH3 + x2 C10H22 + (1 − x1 − x2) Cl(CH2)3CH3} and the corresponding binary mixtures, with an Anton Paar densimeter. All the experimental values were compared with the results obtained by different prediction methods.

Chandramouli, J., Choudary, N.V., Krishnaiah, A. and Naidu, P.R., 1982. Thermodynamic properties of binary liquid mixtures involving weak interactions. Part 1. Excess volumes of binary mixtures of 1-chlorobutane with normal alkanols at 303.15 K. Fluid Phase Equilibria , 8: 87–92 Excess volumes for binary mixtures of 1-chlorobutane with 1-propanol, 1-butanol, 1-pentanol, 1-hexanol, 1-heptanol and 1-octanol have been determined at 303.15 K. V E is positive over the whole range of composition for the mixtures of 1-chlorobutane with 1-propanol and 1-butanol. An inversion in the sign of V E is observed over certain ranges of concentration of the halogenated alkane in the remaining four mixtures. The results are explained in terms of depolymerisation of hydrogen-bonded alcohol aggregates, decrease in dipolar association, and weak hydrogen-bonding interaction of the type Cl- - - HO between unlike molecules.

The vapour—liquid equilibria (VLE) for the binary systems formed by 1-chloropropane with benzene and cyclohexane at 308.15 K and 318.15 K, and for systems formed by 1-chlorobutane with the same hydrocarbons at 308.22 K, 328.27 K and 348.31 K have been determined by a total pressure ebulliometric method. The accuracy of these results was proved by comparing the heat of mixing data calculated from these VLE results with those obtained by direct measurements (Amaya, 1961; Grolier et al., 1973). The experimental data and the results of correlation by means of the Redlich—Kister equation are given. The systems with benzene were found to be nearly ideal, while those with cyclohexane exhibit positive deviations (GE = 220–260 J mole−1 for an equimolar mixture). New vapour pressure versus temperature data for 1-chlorobutane are reported.
