Prediction of thermophysical and transport properties of ternary organic non-electrolyte systems including water by polynomials

Abstract

The description and prediction of thermophysical and transport properties of ternary organic non-electrolyte systems including water by polynomial equations are reviewed. Empirical equations of Radojkovii et al. (also known as Redlich-Kister), Kohler, Jacob-Fitzner, Colinet, Tsao-Smith, Toop, Scatchard et al. and Rastogi et al. are compared with experimental data of available papers that appeared in well know international journals (Fluid Phase Equilibria, Journal of Chemical and Engineering Data, Journal of Chemical Thermodynamics, Journal of Solution Chemistry, Journal of the Serbian Chemical Society, The Canadian Journal of Chemical Engineering, Journal of Molecular Liquids, Thermochimica Acta, etc.). The applicability of empirical models to estimate excess molar volumes, VE, excess viscosities, Δ, excess free energies of activation of viscous flow, ΔG*E, molar refraction changes on mixing, ΔR, changes in the refractive indices on mixing, ΔnD, changes of isentropic compressibility, Δκs, surface tension deviations, Δσ, speed of sound deviations, Δu, relative permittivity deviations, σε-r, were checked on the series of ternary mixtures of very complex structure, which is described very shortly. The obtained results of prediction are discussed and some recommendations about the use of symmetric or asymmetric models to the possible application to mixtures are made. © 2013 (CC) SCS.
