Viscosity of near-boiling nonassociated liquids: dependence on surface tension, molecular mass and intramolecular conformational transitions

摘要

The equation proposed for near-boiling nonassociated liquids describes a new functional dependence of their viscosity on such physico-chemical characteristics as surface tension and molecular mass. It is shown that the viscosity of liquids with conformationally flexible molecules can be calculated adequately by taking into account the influence of intramolecular conformational transitions on the number of bimolecular collisions in the liquid phase.
