Excess molar volumes and excess viscosities, at 298.15 K, of the ternary mixtures (2-butanol + 1-chlorobutane + 1-butylamine) and (2-methyl-2-propanol + 1-chlorobutane + 1-butylamine) and of the binary mixtures (2-butanol + 1-butylamine), (2-methyl-2-propanol + 1-butylamine), and (1-chlorobutane + 1-butylamine) have been measured. The ternary excess properties were fitted to the polynomial equation of Cibulka. The experimental results were also compared with those predicted by the empirical equations of Redlich–Kister, Tsao–Smith, Kohler, and Colinet. Keywords: binary and ternary mixtures, excess properties, 2-butanol, 2-methyl-2-propanol, 1-chlorobutane, 1-butylamine.

Densities and viscosities were determined for the 2-propanol + methylacetate + dichloromethane system at 298.15 K. From the experimental results, molar excess volumes and excess viscosities were calculated. Different expressions exist in the literature to predict these excess properties from the binary mixtures. The empirical correlation of Tsao–Smith and Toop is the best for this system.

Excess molar volumes and excess refractive indices of the n-octanol + 1,4-dioxane + 2-butanol system and the three corresponding binary mixtures have been determined at 298.15 K by measuring densities and refractive indices. Different expressions exist in the literature to predict these excess properties from binary data. An estimation of excess molar volumes is also evaluated using a modified Heller equation which depends on the refractive indices of the mixtures. A comparison of the predictions of different methods with the experimental values of the physical properties has been made.Key words: excess molar volumes, densities, refractive indices, n-octanol, 1,4-dioxane, 2-butanol, ternary system.

Densities and viscosities have been determined for binary mixtures of 1-iodobutane with benzene, toluene, o-xylene, m-xylene, p-xylene, and mesitylene at 303.15, 308.15, and 313.15 K for the entire composition range at atmospheric pressure. The excess molar volumes, , deviations in viscosity, Δη, and excess Gibbs’ free energy of activation flow, Δ have been calculated from the experimental values. The experimental data were fitted to Redlich-Kister polynomial equation. The variations of these parameters with composition of the mixtures and temperature have been discussed in terms of molecular interactions occurring in these mixtures. Further, the viscosities of these binary mixtures were calculated theoretically from their corresponding pure component data by using empirical relations like Bingham, Arrhenius and Eyring, Kendall and Munroe, Hind, Katti and Chaudhari, Grunberg and Nissan, and Tamura and Kurata. Comparison of various interaction parameters has been expressed to explain the intermolecular interactions between iodobutane and selected hydrocarbons.

From experimental densities, viscosities, and refractive indexes for the acetylacetone + 1-pentanol, + 2-Pentanol, + isoamyl alcohol, and + tert-amyl alcohol systems at 298.15 K, the excess molar volumes, excess viscosities, excess molar free energies of activation of flow, and excess internal pressures were calculated over the whole concentration range. Conclusions about the molecular interactions in these mixtures were drawn from the variations of the excess functions with the composition.
