ABSTRACT

Isothermal vapor liquid equilibrium data at 333.15K are measured for the binary systemethanol + 2,2,4- trimethylpentane and for ternary system di-methyl carbonate (DMC) + ethanol + 2,2,4-trimethylpentane by using headspace gas chromatography. The experimental binary and ternary vapor liquid equilibrium data were correlated with different activity coefficient models. Excess volume and deviations in molar refractivity data are also reportedfor the binary systemsDMC+ ethanol andDMC+ 2,2,4-trimethylpentane and the ternary system DMC+ ethanol + 2,2,4-trimethylpentane at 298.15 K. These data were correlated with the Redlich-Kister equation for the binary systems and the Cibulka equation for the ternary system, respectively. The ternary excess volume and deviations in molar refractivity data were also compared with estimated values from the binary contribution models of Tsao Smith, Kohler, Rastogi and Radojkovi!c.
