Experimental pressures as a function of temperature, density, and mole fraction x of xenon along the critic al line of {xXe + (1 - x)CO2} have been obtained using a precise (p, rho, T) instrument in the temperature range (301.69 to 303.15) K, the density range (468.0 to 502.4) kg.m(-3), the mole fraction range (0 to 4.2067 . 10(-2)), and the pressure range (7.2916 to 7.3883) MPa.
