Experimental densities for the CO2 (1) + thiophene (2) binary mixtures are reported from 313 to 363K and up to 25MPa. Densities were measured for thiophene and for binary mixtures at five different compositions, x1 = 0.1990, 0.3818, 0.5661, 0.6996, and 0.9217. Densities of thiophene were correlated by four different models, the Benedict Webb Rubin Starling equation of state (BWRS EoS), the Tait equation (TE), the Toscani and Szwarc (TS) model, and a proposed modification for this last model (MTS). These models represent densities of thiophene with a percent standard deviation of 3.90*10-3, 1.97*10-2, 2.76*10-2, and 5.54*10-3, respectively. The excess molar volumes were determined using densities for thiophene calculated from the BWRS EoS and densities for CO2 calculated from the Span Wagner EoS. The volumetric behavior and excess molar volumes of CO2 + thiophene mixtures were modeled using the PC-SAFT EoS.
