摘要：

Isothermal P-x data (VLE) and excess enthalpy (H-E) data for the two binary systems benzene + benzonitrile and toluene + benzonitrile have been measured by means of a computer-operated static apparatus and an isothermal flow calorimeter. Activity coefficients at infinite dilution gamma(i)(infinity) have been derived by fitting a flexible Legendre polynomial to the experimental VLE data. Temperature-dependent interaction parameters for different excess Gibbs energy (G(E)) models have been fitted simultaneously to the experimental VLE and H-E data. The experimental results have been compared with the data of other authors.
