摘要：

Liquid-vapor isotherms for the binary mixtures CO//2 plus n-hexylbenzene, n-heptylbenzene, and n-octylbenzene were experimentally studied in the temperature range of minus 5 to 45 degree C. Liquid phase compositions and molar volume are reported as a function of pressure. Vapor phase compositions and molar volumes are also reported for some of the 35 and 45 degree C isotherms. Subcritical isothermal behavior for some of the isotherms near three-phase liquid-liquid-vapor loci is interpreted as being analogous to that seen for isotherms exhibiting supercritical extraction. This claim is supported by arguments based on Gibbs energy diagrams.
