ABSTRACT

Excess molar enthalpy (HE) data and vapor-liquid equilibria (VLE) were measured for the ternary system toluene + ethylbenzene + chlorobenzene. Ternary HE values were measured with a Calvet-type microcalorimeter at 298.15 K. These results together with literature HE data of constituent binaries were used for a correlation with the modified Redlich-Kister equation. Boiling temperature (T)-liquid composition (x) relations were obtained at (26.66, 53.33, 79.99, and 101.32) kPa by using a semimicroebulliometer. The modified Wilson model with parameters that linearly depend on temperature was used to correlate the binary T-x data and to predict VLE in the ternary system. Excess functions at 298.15 K were compared.
