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, sulphur hexafluoride–isopropanol) were measured at temperatures 313.15 K 333.15 pressures up to 100 bar for carbon dioxide, argon hexafluoride 500 bar. A vibrating tube densimeter method has been used density measurements a variable-volume high-pressure optical view cell with some modifications the other measurements. The results showed that pressure does not have high impact on viscosity. Density is found be linear function temperature densities investigated increase decrease temperature. Interfacial decreased elevated constant all systems. Accurate prediction thermodynamic mass transfer data fundamental in various engineering industrial operations design processes higher yield targeted compounds.
