Densities and viscosities of binary mixtures of butanone with butanol isomers at several temperatures

Densities and viscosities of butanone+1-butanol, +2-methyl-1-propanol, +2-butanol, or +2-methyl-2-propanol were measured at several temperatures between 288.15 and 318.15 K. At each temperature, the experimental viscosity data were correlated by means of the McAllister bi-parametric equation and according to the model, the four pairs of activation parameters (ΔHj*, ΔSj*) have been calculated. By using our previous thermodynamic measurements (VLE, HE), we have tested the Wei and Rowley non-parametric model, at T=298.15 K, obtaining average absolute deviations which are comparable to those calculated for the bi-parametric model.
