Resumo
© 2022 Elsevier LtdDensity, speed of sound and viscosity of binary mixtures of {acetonitrile + ethylene glycol (EG), or + diethylene glycol (DEG), or + triethylene glycol (TEG)} have been measured as a function of compositions at temperatures of 288.15, 293.15, 298.15 and 303.15 K and under atmospheric pressure. Excess molar volume, partial molar volume, excess partial molar volume, deviation in isentropic compressibility and deviation in viscosity were determined and excess properties have been fitted to the Redlich-Kister equation. The empirical models developed by Grünberg-Nissan, Heric-Brewer, Katti-Chaudhary and Van der Wyk were used to correlate the experimental viscosity data. The excess molar volume was also used to test the applicability of the Peng-Robinson-Stryjek-Vera equation of state (PRSV EOS).
