摘要：

The saturated vapor pressure in the temperature range of 298.15–308.15 K and the density of solutions in the o-xylene–di-2(ethylhexyl)phosphoric acid system at 298.15 K are measured. The activity coefficients of o-xylene in the above temperature range are calculated on the basis of the resulting data. The parameters of the thermodynamic model UNIQUAC are determined and analytical relationships are proposed to describe the bulk properties of the solution. © 2016, Allerton Press, Inc.
