ABSTRACT

Densities, viscosities, and refractive indexes were measured for the binary mixtures formed by methanol, ethanol, propan-1-ol, and butan-1-ol with 1-chlorobutane at T ) (288.15, 298.15, and 308.15) K and atmospheric pressure over the whole concentration range. Excess molar volumes (VE) were determined from the densities of pure liquids and mixtures measured with a vibrating-tube densimeter. Excess molar volumes, which increase as the temperature increases, are positive except for mixtures in the high mole fraction region of propan-1-ol or butan-1-ol. Viscosities were measured with an automatic Ubbelohde capillary viscometer. Refractive indexes were measured using a digital refractometer. Deviations in viscosity and deviations in refractive index as a function of mole fraction for the mixtures were derived from the experimental data. The computed results of VE, viscosity deviations, and deviations in the refractive index were fitted to the Redlich-Kister equation. Furthermore, McAllister?s three-body interaction model is used to correlate the binary kinematic viscosities.
