Multiphase equilibrium behavior of the mixture carbon dioxide + ethane + methanol

摘要: There is considerable interest in the use of methanol, ethanol, and other polar molecules as cosolvents super-critical extraction processes, wherein cosolvent methanol would enhance ability a solvent gas, carbon dioxide, e.g., to solubilize liquid- or solid-phase species. The three-phase liquid-liquid-vapor (11g) phase equilibrium behavior mixture dioxide + ethane was experimentally studied. boundaries 11g region pressure-temperature space are delineated. Compositions molar volumes two liquid phases vapor along 288.15 298.15 K isotherms reported.
