Densities and viscosities of the binary mixtures of phenylmethanol with 2-butanone

Densities and viscosities of the binary systems of phenylmethanol with 2-butanone were measured for the entire composition range at T = (303.15, 308.15, 313.15, 318.15, and 323.15) K and at the atmospheric pressure. The excess molar volumes were derived from the experimental data and were fitted with the Redlich-Kister equation to obtain their coefficients and standard deviations. The Grunberg-Nissan equation was used to correlate the viscosity data. Furthermore, kinematic viscosities were compared with those predicted by the UNIFAC-VISCO model. The cause of relatively large deviations between the experimental and predicted kinematic viscosities was explored by comparing the combinatorial and residual terms of the UNIFAC-VISCO model. © 2011 American Chemical Society

Erratum: Density and viscosity of the binary mixtures of hexan-1-ol with isomeric xylenes at T = (308.15 and 318.15) K and atmospheric pressure

金沢大学理工研究域物質化学系Densities and viscosities of binary liquid mixtures of hexan-1-ol + o-xylene, + m-xylene, or + p-xylene were measured at a number of mole fractions at T = (308.15 and 318.15) K and atmospheric pressure. The excess volumes and the viscosity deviations from the mole fraction average were calculated from the experimental density and viscosity data. The experimental data were correlated with Redlich-Kister equation. Variations in the calculated excess and deviation properties for the liquid mixtures were studied in terms of intermolecular interactions. © 2010 American Chemical Society

Viscometric behavior of binary mixtures of butan-2-one with benzene at T = (303.15, 313.15, and 323.15) K

金沢大学理工研究域物質化学系Viscosities of binary liquid mixtures of butan-2-one with benzene were measured at a number of mole fractions at T = (303.15, 313.15, and 323.15) K and atmospheric pressure. The viscometric behavior is discussed on the basis of structural and geometrical effects between the components. In addition, kinematic viscosities were calculated using the UNIFAC-VISCO model. The predicted kinematic viscosities are in good agreement with the experimental ones. © 2011 American Chemical Society
