Densities and viscosities of mixtures of nitrobenzene with methanol, ethanol, propan-1-ol, propan-2-ol, butan-1-ol, 2-methylpropan-1-ol, and 2-methylpropan-2-ol were measured at 298.15 and 303.15 K. From these measurements, the excess volumes (V-E) and deviation in viscosity (Delta eta) were calculated. These results were fitted to the Redlich-Kister polynomial.
