ABSTRACT

Densities of the ternary system 1-butanol + hexylamine + n-heptane and binaries: 1-butanol + hexylamine and hexylamine + n-heptane within the temperature range (288.15 323.15 K) and atmospheric pressure are reported. Excess molar volumes were calculated from the density data and fitted by the Redlich-Kister and Nagata and Tamura equations. The results are analyzed in terms of the molecular interactions between the components of mixtures. Several empirical relationships (Radojkovic, Kohler, Jacob-Fitzner, Colinet, Tsao-Smith, Toop, Scatchard and Rastogi) were applied for prediction of excess molar volume data of the ternary system from the corresponding binary data. For the correlation of binary excess molar volume, the Peng-Robinson-Stryjek-Vera cubic equation of state (PRSV CEOS) coupled with the van der Waals (vdW1) and CEOS/GE mixing rule introduced by Twu et al. (TCBT) were chosen. Prediction of excess molar volume of ternary system was performed by the same vdW1 and TCBT models. For the correlation of the excess molar volume of ternary data only TCBT mixing rules were used.
