ABSTRACT

Vapor liquid equilibrium data p, T, x, ?, and Vm at (293.2, 313.2, 333.2, and 353.2) K and pressures between (1.39 and 9.96) MPa for the binary systems of carbon monoxide (CO) + propionic acid (PA) and carbon monoxide + methyl formate (MF) were reported. The equilibria were measured using a variable-volume cylindrical autoclave. The experimental data were modeled using the Peng Robinson (PR) equation of state (EOS) and Peng Robinson Stryjek Vera (PRSV) equation of state with van der Waals I or Panagiotopoulos Reid mixing rules. The compared results showed a satisfactory agreement between the correlated and the experimental data. The binary interaction parameters were also obtained. At the same time, the Henry's coefficient, molar solution enthalpy, and molar solution entropy of CO in propionic acid and methyl formate were calculated.
