Abstract
The vapour pressures of binary mixtures 2-methylpyridine with cyclohexane, n-heptane or toluene were measured by a static method in the range from 263.15 to 353.15 K. The pure components vapour pressures data and those of the mixtures were correlated with the Antoine equation. The excess enthalpies were measured at 303.15 K, by means of an isothermal calorimeter (C80 SETARAM model). The molar excess Gibbs energies, calculated from the vapour–liquid equilibrium data and the molar excess enthalpies compared satisfactorily with group contribution model (DISQUAC).
