Vapor–Liquid Equilibrium Measurements of the Binary Mixtures Nitrogen + Acetone and Oxygen + Acetone

Vapor–liquid equilibrium data of the binary mixtures nitrogen + acetone and oxygen + acetone are measured and compared to available experimental data from the literature. The saturated liquid line is determined for both systems at specified temperature and liquid phase composition in a high-pressure view cell with a synthetic method. For nitrogen + acetone, eight isotherms between 223 K and 400 K up to a pressure of 12 MPa are measured. For oxygen + acetone, two isotherms at 253 K and 283 K up to a pressure of 0.75 MPa are measured. Thereby, the maximum content of the gaseous component in the saturated liquid phase is 0.06 mol/mol (nitrogen) and 0.006 mol/mol (oxygen), respectively. On the basis of these data, the Henry’s law constant is calculated. In addition, the saturated vapor line of nitrogen + acetone is studied at specified temperature and pressure with an analytical method. Three isotherms between 303 K and 343 K up to a pressure of 1.8 MPa are measured. All present data are compared to the available experimental data. Finally, the Peng–Robinson equation of state with the quadratic mixing rule and the Huron–Vidal mixing rule is adjusted to the present experimental data for both systems.
