20.500.12556/DKUM-85073 Determination of viscosity, density and interfacial tension of the carbon dioxide–isopropanol, argon–isopropanol, sulphur hexafluoride–isopropanol binary systems at 313.15 K and 333.15 K and at elevated pressures Viscosity, density, and interfacial tension of three binary systems (carbon dioxide–isopropanol, argon–isopropanol, and sulphur hexafluoride–isopropanol) were measured at temperatures of 313.15 K and 333.15 K and at pressures up to 100 bar for carbon dioxide, and for argon and sulphur hexafluoride up to 500 bar. A vibrating tube densimeter method has been used for density measurements and a variable-volume high-pressure optical view cell with some modifications for the other measurements. The results showed that pressure does not have a high impact on viscosity. Density is found to be a linear function of pressure and temperature and the densities of the investigated binary systems increase with pressure and decrease with temperature. Interfacial tension decreased with the elevated pressure at a constant temperature for all the investigated systems. Accurate prediction of thermodynamic and mass transfer data is fundamental in various engineering and industrial operations to design processes with a higher yield of targeted compounds. viscosity interfacial tension carbon dioxide argon suplhur hexafluoride isopropanol viskoznost tenzija ogljikov dioksid isopropanol true false true MDPI AG Angleški jezik Slovenski jezik https://www.mdpi.com/journal/processes © 2022 by the authors Znanstveno delo 2023-08-17 15:06:14 2023-08-17 15:06:14 2025-05-15 08:42:32 0000-00-00 00:00:00 2022 0 0 13 str. iss. 11 Vol. 10 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2022-10-07 2022-10-27 2022-11-03 66.02 128184579 10.3390/pr10112275 2227-9717 Determination_of_Viscosity,_Densit-Borjan-2022.pdf Determination_of_Viscosity,_Densit-Borjan-2022.pdf 1 8446BD9781E9A9199893553973B50CC1 69eded31ce25ee17fc1e95ad83542503287d7f6515d5c541ca2e301dde209c87 312229a9-3cff-11ee-af21-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=169683 https://www.mdpi.com/2227-9717/10/11/2275 0 379b31e5-3cff-11ee-af21-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=169684 Fakulteta za kemijo in kemijsko tehnologijo Medicinska fakulteta 0 0 0
