ABSTRACT

Isothermal vapor liquid equilibrium data at 333.15K are measured for the binary systemtert-amylmethyl ether + ethanol and tert-amyl methyl ether + 2,2,4-trimethylpentane and for ternary system tert-amyl methyl ether + ethanol + 2,2,4-trimethylpentane by using headspace gas chromatography. The experimental vapor liquid equilibrium datawere correlated with GE models (Margules, van Laar,Wilson, NRTL, UNIQUAC) equations. The excess volume and deviations in molar refractivity data are also reported for the same binary and ternary systems at 298.15 K. These datawere correlated with the Redlich Kister equation for the binary systems and the Cibulka equation for the ternary system, respectively. The experimental ternary excess volume and deviations in molar refractivity data, were also compared with the estimated values from the binary contribution models of Tsao Smith, Kohler, Rastogi and Radojkovi!c.
