Isothermal (vapour + liquid) equilibrium data for the binary systems of (CO + methyl propionate) and (CO + ethyl propionate) were measured at temperatures of (293.15, 313.15, 333.15, 353.15, and 373.15) K and at elevated pressures up to 10.00 MPa. The measurements were carried out in a cylindrical autoclave with a moveable piston and an observation window. The experimental results were correlated using the Peng–Robinson (PR) equation of state and Peng–Robinson–Stryjek–Vera (PRSV) equation of state with the two-parameter van der Waals II or Panagiotopoulos–Reid mixing rule. The comparisons of the calculation results with experimental values indicate that the PRSV equation of state with van der Waals II mixing rule produced the better correlated results.
► Phase equilibria of two binary systems containing carbon monoxide were studied. ► Measurements were carried out over wide range of temperature and pressure. ► Mole composition, density and molar volumes were obtained. ► Experimental data were correlated and the interaction parameters were presented. ► Calculated results and experimental data obtained good agreements.
