摘要：

A new apparatus for the rapid determination of fluid phase equilibria up to 300 bar and 120°C is described. VLE measurements of the 37.8°C isotherm of the CO2-n-butane system as well as the 40°C isotherm of the CO2-acetone system compare well with results obtained by other authors. New VLE and VLLE data are presented for the CO2-water-acetone system at 40°C and pressures of 40 bar and 100 bar. The results, correlated with a modified Redlich-Kwong-Soave equation of state with mixing rules proposed by Huron and Vidal, are interpreted with respect to the extractability of acetone from diluted aqueous solutions using compressed CO2 as the solvent. © 1990.
