Excess Molar Volumes and Enthalpies of Binary Mixtures Containing Furan and Toluene, 1-Octanol or n-Hexane at Temperatures Up to 383.15 K and Pressure Up to 1.6 MPa

Densities of pure furan, toluene, 1-octanol, n-hexane and of binary liquid mixtures containing furan, have been measured from 303.15 to 383.15 K at pressures up to 1.6 MPa, using a vibrating tube densimeter. Excess molar volumes have been calculated from the densities with an average standard uncertainty 0.02 cm(3)center dot mol(-1). Excess molar enthalpies of the binary mixtures were measured at temperatures ranging from 313.15 to 383.15 K at 0.5 MPa and/or 1.0 MPa, using flow mixing calorimeter. The average standard uncertainty on the whole measurements is less than 1%. The excess molar properties derived from experimental data were correlated using Redlich-Kister polynomial functions and NRTL activity coefficient model and Prigogine-Flory-Patterson modelling is described and used to correlate the data.
