【 摘 要 】

References(23)Cited-By(24)A new experimental method of vapor–liquid equilibria at high pressures for binary systems which requires no analysis of phase compositions is proposed in the present study. The equilibrium vapor and liquid compositions can be evaluated by combining a couple of data at the same temperature and pressure, based on mass balance and the phase rule. A new apparatus for vapor–liquid equilibria at high pressures was constructed for use with the present experimental method. Vapor–liquid equilibria and saturated densities at high pressures were measured for the carbon dioxide–acetone system at 298.15 K. The experimental data obtained were correlated with the pseudocubic perturbed hard-sphere equation of state proposed previously.
