| Abstract: | The liquid-liquid-vapor loci for the binary mixtures CO2 + n-hexylbenzene, n-heptylbenzene, and n-octylbenzene were experimentally studied. The compositions and molar volumes of the liquid phases are reported along with the pressure and temperature. For these three alkylbenzenes, the nature of the liquid-liquid-vapor loci experiences a transition, with the CO2 + n-heptylbenzene mixture exhibiting two separate liquid-liquid-vapor branches. |
