Abstract
The kinematic viscosity of n-nonane mixtures with propan-1-ol, butan-1-ol, and pentan-1-ol was measured over the temperature range 293.15–313.15 K. For all systems, negative deviations of viscosity from additive values were obtained; the deviations increased in magnitude as the temperature and alkan-1-ol hydrocarbon radical length increased. The activation energy of viscous flow was calculated in terms of the Eyring theory and free volume theory in the usual and extended (with the inclusion of molecular association) variants at equimolar mixture compositions. The behavior of the concentration dependences of viscosity and the activation energy of viscous flow in alkan-1-ol-n-alkane mixtures was found to be controlled by molecular association processes.
