چکیده	Experimental high-temperature, high-pressure (HTHP) density of three solvents including dimethyl sulfoxide, benzyl alcohol, and isoamyl acetate were measured at temperatures of 293.15 to 473.15 K and pressures up to 35–37.5 MPa. The density was measured with an Anton Paar density meter (DMA HP) in 20 K and 2.5 MPa intervals. The experimental data were correlated with the Tait and new modified Tait equations. Thermal expansion coefficient ( ) and isothermal compressibility ( ), were calculated with the new modified Tait equations. Moreover, perturbed-chain statistical associating fluid theory (PC-SAFT) equation of state (EoS) was used to model the density data at HTHP. Although, in most cases the parameters are obtained from saturated vapor pressure and liquid phase density, they were calculated from the density at HTHP. With these parameters thermodynamic properties such as thermal expansion coefficient ( ), isothermal compressibility ( ), isobaric heat capacity ( ), and speed of sound ( ) were calculated. Acceptable agreement between the results with experimental data demonstrated the accuracy of modeling with obtained parameters.
