Thermodynamic properties of solutions in the system o-xylene−di-2-(ethylhexyl)phosphoric acid


Saturated vapor pressure in temperature range 298.15−308.15 K and density of solutions in the system o-xylene − di-2(ethylhexyl)phosphoric acid at 298.15 K were measured. Activity coefficients of o-xylene in the investigated temperature range were calculated based on these data. Parameters of the thermodynamic model UNIQUAC were defined and analytical relationships to describe the bulk properties of the solution were proposed.
Key words: vapor pressure, activity coefficients, density, di-2(ethylhexyl)phosphoric acid, o-xylene, excess molar volume.
