PHASE-EQUILIBRIA IN THE BINARY-SYSTEM CARBON-DISULFIDE CARBON-DIOXIDE

Vapor-liquid and three-phase equilibrium compositions for the binary system carbon disulfide-carbon dioxide have been measured at eleven temperatures ranging from 273.15 to 473.15 K At subcritical temperatures the pressure at each temperature ranged from the vapor pressure of carbon disulfide to the vapor pressure of carbon dioxide. Above the critical temperature of carbon dioxide the pressures were extended to the vicinity of the critical region at about 16 MPa. The data were used to investigate the correlative capability of two empirical equations of state as well as the predictive capability of a molecular model based on perturbation theory.
