Excess volumes and viscosities of binary mixtures of aliphatic alcohols (C-1-C-4) with nitromethane

Densities and viscosities were measured for the binary mixtures of methanol , ethanol, propan-1-ol, propan-2-ol, butan-2-ol, and 2-methyl-propan-2-ol w ith nitromethane at temperatures from 293.15 K to 313.15 K and atmospheric pressure. Densities were determined using a vibrating-tube densimeter. Visc osities were measured with an automatic Ubbelohde capillary viscometer. The estimated uncertainties are less than +/-0.0001 g.cm(-3) for density and /-0.7% for viscosity. Excess volumes and viscosity deviations as a function of mole fraction average were derived, and the computed results were fitte d to the Redlich-Kister equation. Furthermore, McAllister's three-body-inte raction model is used to correlate the binary kinematic viscosities.
