Volumetric and Viscometric Properties of Binary Mixtures of Aliphatic Alcohols (C₁−C₄) with Nitroethane from 293.15 K to 313.15 K

Abstract

Densities and viscosities were measured for the binary mixtures of methanol, ethanol, propan-1-ol, propan-2-ol, butan-2-ol, and 2-methylpropan-2-ol with nitroethane at temperatures from 293.15 K to 313.15 K and atmospheric pressure. Densities were determined using a vibrating-tube densimeter. Viscosities were measured with an automatic Ubbelohde capillary viscometer. The estimated uncertainties are less than ±0.05% 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 fitted to the Redlich−Kister equation. Furthermore, McAllister's three-body-interaction model is used to correlate the binary kinematic viscosities and the binary densities.
