DENSITIES AND VISCOSITIES OF 2-BUTANONE/DIBUTYL ETHER, 2-PICOLINE/2-BUTANONE, AND 2-PICOLINE/WATER MIXTURES

Densities and viscosities of the binary mixtures including 2-butanone/dibutyl ether, 2-picoline/2-butanone, and 2-picoline/water are measured at 303.15, 313.15, and 323.15 K over the entire molar fraction range. The excess volumes, viscosities, and Gibbs energies of activation of flow are calculated from the experimental data, and are correlated by a Redlich-Kister-type function in terms of molar fraction. McAllister's three-body and four-body interaction models are also used to correlate the kinematic viscosities.
