Thermodynamics of organic mixtures containing amines. VIII. Systems with quinoline
چکیده انگلیسی

(Solid + liquid) equilibrium temperatures for mixtures containing quinoline and 1-dodecanol, 1-hexadecanol, or 1-octadecanol have been measured using a dynamic method. (Quinoline + benzene, +alkane, or +1-alkanol) systems were investigated using DISQUAC. The corresponding interaction parameters are reported. The model yields a good representation of molar excess Gibbs free energies, GE, molar excess enthalpies, HE, and of the (solid + liquid) equilibria, SLE. Interactional and structural effects were analysed comparing HE and the molar excess internal energy at constant volume, UVE. It was encountered that structural effects are very important in systems involving alkanes or 1-alkanols. Interactions between amine molecules are stronger in mixtures with quinoline than in those containing pyridine, which was ascribed to the higher polarizability of quinoline.
