Viscosities and densities have been measured for octane + butan-1-ol, hexan-1-ol and odan-1-ol at 298.15 K and at atmospheric pressure. Kinematic viscosities were determined using a capillary viscosimeter, and densities were measured by vibrating-tube densimetry. The results were fitted to the equations of Grunberg-Nissan, McAllister, Auslander, and Teja. The experimental excess molar volumes were compared with the results obtained with the Nitta-Chao model.
