Abstract: The viscosities, densities and ultrasonic velocities of binary liquid mixtures of methanol with piperidine and morpholine and pyridine with piperidine and morpholine have been determined at 303.15 to 318.15K over the entire composition range. These data have been utilized to estimate the excess free volume, excess internal pressure, excess enthalpy, excess velocity, excess acoustic impedance and excess Gibb’s free energy of activation of flow. The results obtained have been discussed in the light of existing theories of molecular interaction involved and chemical constitution of the liquid components. Analysis of these parameters indicates that there are intermolecular interactions among components of the binary mixtures that lead to possible hydrogen bond formation (of the type N…H-O) between unlike molecules.
