Shear viscosities of binary mixtures of pyrrolidin-2-one with C6–C10n-alkan-1-ols

Excess viscosities and excess Gibbs energies of activation for viscous flow at five temperatures have been calculated for binary liquid mixtures of pyrrolidin-2-one with (C6–C10) alkan-1-ols from the experimental densities and viscosities of the mixed fluids. The excess viscosities and excess Gibbs energies of activation were negative, and increased with increasing temperature. The fitting of viscosities to the one-parameter (d) Nissan–Grunberg equation, and the two-parameter (ν12 and ν21) McAllister equation was extended to the C1–C5 alkanols using earlier results, and examined in terms of interactions between unlike molecules. The ν12 and ν21 parameters were positive and increased with increasing temperature. A minimum in the excess Gibbs energies and d values at equimolar concentrations of the two components has been observed for the pyrrolidin-2-one–pentan-1-ol system.
