The (p, ? , T, x) properties of binary mixtures of CO 2 (volume fraction purity 0.99999) and propane (mole fraction purity 0.9999) ( x 1 CO 2 +x 2 propane; x 1 =0.1744 , 0.3863, 0.5837, and 0.7732) were measured in the compressed liquid phase using a metal-bellows variable volumometer. Measurements were conducted from 280 K to 440 K and 3 MPa to 200 MPa. The expanded uncertainties ( k=2 ) were estimated to be temperature, less than 3 mK; pressure, 1.5 kPa ( p=7 MPa), 0.06 % (7 MPa less thanp=50 MPa), 0.1 % (50 MPa less thanp=150 MPa), 0.2 % ( pgreater than150 MPa); density, 0.10 %; and composition, 4.4*10 -4 . At pgreater than100 MPa and 280 K or 440 K, the uncertainties in density measurements increase to 0.14 % and 0.22 %, respectively. The data were compared with available equations of state. The excess molar volumes, v E m , of the mixtures were calculated and plotted as a function of temperature and pressure.
