Resumo

Ultrasonic velocities (u), densities (ρ), viscosities (η), relative permittivities (εr), and refractive indices (nD) of mixtures of methanol (MeOH) with pyridine and N,N-dimethylformamide (DMF) have been measured at 25 °C. From u, ρ, and η, deviation in isentropic compressibilities ( ), excess volumes (VE), and viscosities (Δη) have been computed. From nD and εr values, the Kirkwood correlation factor, g, has been evaluated. The variation of such properties shows specific interactions between the components of MeOH + pyridine and MeOH + DMF binary mixtures.
