ABSTRACT

Isothermal vapor-liquid equilibrium (VLE) data are reported for the binary system dibutyl ether (DBE) + 2,2,4-trimethylpentane at 333.15 K, as well as for the ternary system DBE + ethanol + 2,2,4-trimethylpentane using headspace gas chromatography. The experimental binary and ternary VLE data are correlated with common activity coefficient models. Excess volumes and deviations in molar refractivity data are also reported for the same binary and ternary systems at 298.15 K. These properties are correlated with the Redlich-Kister equation for binary systems and the Cibulka equation for ternary systems, respectively. The ternary excess volumes and deviations in molar refractivity data are also compared with the estimated values from the binary contribution models of Radojkovi, Tsao-Smith, Kohler, and Rastogi.
