Densities and Viscosities of the Binary Mixtures of Phenylmethanol with 2-Butanone

Abstract

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.
