Densities and viscosities for binary mixtures of n-heptane with alcohols at different temperatures

Maria Magdalena Budeanu, Vasile Dumitrescu


Densities (ρ) and viscosities (η) of the binary systems n-heptane with alcohols (ethanol, n-propanol and iso-propanol) were measured at temperatures between 288.15 and 308.15 K and atmospheric pressure, over the whole composition range. The excess values of molar volume (VE) and viscosity (ηE) were calculated from experimental measurements. The excess functions of the binary systems were fitted to Redlich-Kister Equation. Comparison between experimental excess molar volume and that calculated from Flory and Prigogine-Flory-Patterson theories has also been made. Viscosity results were fitted to the equations of Grunberg-Nissan, Heric-Brewer, Jouyban-Acree and McAllister. Also, the activation energies of viscous flow have been obtained and their variations with compositions have been discussed.
