ABSTRACT

Isothermal vapor liquid equilibrium (VLE) data are reported at three temperatures, (343.15, 353.15, and 363.15) K, for the binary mixtures containing nitromethane or nitroethane with 1,3-dichloropropane. For the measurements an all-glass ebulliometer was used, which allows sampling from both phases in equilibrium. The experimental data were correlated using the nonrandom two-liquid (NRTL) and universal quasichemical activity coefficient (UNIQUAC) excess Gibbs energy models by means of maximum likelihood method, taking into account the vapor phase imperfection in terms of the second virial coefficients. Both systems are azeotropic and show positive deviations from ideal behavior. The experimental VLE data are analyzed in terms of the modified UNIFAC (Do) model.
