Experimental measurements and modelling of volumetric properties, refractive index and viscosity of selected binary systems with butyl lactate at 288.15–323.15 K and atmospheric pressure. New UNIFAC-VISCO interaction parameters

Prediction of excess molar volumes of selected binary mixtures from refractive index data

“…39 For the butyl lactate+1-propanol mixture, similar results were obtained with all three types of equations and different mixing rules with the exception of the Arago-Biot mixing rule, which again gave higher values of PD max . None of the relations considered could be generally emphasized as superior since the prediction results varied with temperature.…”

“…The predictions of V E from n D data in the temperature range 288.15-323.15 K (or 288.15-333.15 K) and at atmospheric pressure for 22 binary systems (the experimental data were taken from the literature [38][39][40][41][42] and from ongoing investigations) were realised using the three chosen Models I-III with incorporated L-L, D-G, Eyk, A-B, New and Ost mixing rules for the determination the refractive index. The results of V E calculation were assessed by the absolute maximum percentage average deviation PD max : For easier analysis, the investigated systems are classified in six groups of binary mixtures: acetone + alcohols, butyl lactate + alcohols, N-methyl-2-pyrrolidone + alcohols, PEGs + alcohols, pyridine + alcohols and PEGs + aromatics.…”

“…However, detailed investigations of the properties such as density, viscosity and refractive index over a wide range of temperature of these mixtures are still missing in the literature. This work is a continuation of our study of the thermodynamic and transport properties of liquid mixtures containing this kind of compounds [7][8][9].…”
