Evaluation of thermodynamic properties of fluid mixtures by PC-SAFT model

Densities and viscosities of binary mixtures of methyl isobutyl ketone (MIK) with polar solvents namely, 2-propanol, 2-butanol and 2-pentanol, were measured at 7 temperatures (293.15-323.15 K) over the entire range of composition. Using the experimental data, excess molar volumes V-m(E), isobaric thermal expansivity alpha(p), partial molar volumes (V) over bar (m,i) and viscosity deviations Delta eta, have been calculated due to their importance in the study of specific molecular interactions. The observed negative and positive values of deviation/excess parameters were explained on the basis of the intermolecular interactions occur in these mixtures. The Perturbed Chain Statistical Association Fluid Theory (PC-SAFT) has been used to correlate the volumetric behavior of the mixtures. (C) 2014 Elsevier B.V. All rights reserved.
