Abstract:
A new intermolecular effective pair potential function accounting for the long range columbic interactions as an attractions tail is introduced to represent the transport properties (viscosity in particular) of some recently synthesized ionic liquids. This potential is regarded as a simplification of the interactions in ionic liquids molecules which assumed to be spherical in shape in this model. So called collision integrals (Ω(l,s)) are calculated numerically on the basis of the Chapman-Enskog solution of the Boltzmann equation. Results show that new intermolecular effective pair potential function is capable to satisfactorily predict the viscosity of studied ionic liquids based on available experimental data.
