Solubilities of ethanamide (acetamide) and 2-propenamide (acrylamide) in supercritical carbon dioxide were measured at T = (308.2, 318.2, and 333.2) K over the pressure range (9.0 to 40.0) MPa by a flow-type apparatus. The solubility of acetamide (2.3.10(-4) to 31.3.10(-4)) in the overall region of measurements is approximately twice that of acrylamide (1.2 . 10(-4) to 16.3 . 10(-4)). The solubility of both components increases with pressure, and the relative location of the crossover region is observed at about 12.0 MPa. The experimental data were correlated by using the Soave-Redlich-Kwong equation of state (EoS) with the one-fluid van der Waals mixing rule. In addition, the pure Compound properties required for the modeling were also estimated.
