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 Radojković 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, Δη, 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, ΔkS, surface tension deviations, ΔϬ, speed of sound deviations, Δu, relative permittivity deviations, Δεr, 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.

U ovom preglednom radu je dat opis i predskazivanje termofuzičkih i transportnih svojstava trojnih organskih neelektrolitnih sistema, uključujući i vodu pomoću polinoma. Empirijske jednačine Radojkovića i sar. (odnosno Redlich-Kister), Kohlera, Jacob-Fitznera, Colineta, Tsao-Smitha, Toora, Scatcharda i sar. i Rastogia i sar. su poređene sa raspoloživim eksperimentalnim podacima objavljenim u poznatim međunarodnim časopisima (Fluid Phase Equilibria, Journal of Chemical and Engineering Data, Journal of Chemical Theromodynamics, Journal of Solution Chemistry, Journal of the Serbian Chemical Society, The Canadian Journal of Chemical Engineering, Journal of Molecular Liquids, Thermochimica Acta i dr.). Primenljivost empirijskih modela na određivanje dopunske molarne zapremine, VE, dopunskih viskoznosti, Δη, dopunske slobodne energije aktivacije viskoznog toka, ΔG*E , promene molarne refrakcije mešanja, ΔR, promene indeksa refrakcije pri mešanju, ΔnD, promene izentropske kompresibilnosti, ΔkS, odstupanje površinskog napona, ΔϬ odstupanje brzine zvuka, Δu, i odstupanje relativne permitivnosti, Δεr, proverena je na seriji trojnih smeša vrlo složene strukture koje su i elementarno opisane. Dobijeni rezultati predskazivanja su prodiskutovani i date su izvesne preporuke za korišćenje simetričnih i nesimetričnih modela i mogućoj uspešnoj primeni na smeše.
