摘要：

Electrical conductance measurements are reported for tetraethylammonium bromide (Et4NBr), tetrapropylammonium bromide (Pr4NBr), tetrabutylammonium bromide (Bu4NBr), and tetrapentylammonium bromide (Pen(4)NBr) in methanol, acetonitrile, and methanol (1) + acetonitrile (2) binary mixtures at 298.15 K. The conductance data have been analyzed by the Fuoss conductance-concentration equation in terms of the limiting molar conductance (Lambda degrees), the association constant (K-A), and the distance of closest approach of ions (R). The results have been interpreted in terms of ion-ion and ion-solvent interactions.
