Conductance of Asymmetric Iodides of Butyl-Triethyl-Ammonium in Toluene-Acetonitrile Mixtures at 25°C

摘要: Abstract The conductance of ter-BuEt3 NI, sec-BuEt3 iso-BuEt3 n-BuEt3 NI and Bu4 in toluene acetonitrile mixtures has been measured. range dielectric constant the solvent covered from 9,4 to 35,9. densities viscosities were also determined. phoreograms having molar fractions 0,4, 0,5 0,6 those 0,3, 0,4 show similar shape. lie below Onsager limit line. data for salts asymmetric cations analyzed using Fuoss equation unassociated 1–1 electrolytes. salt n-BuEt3NI mole fraction 0,1, 0,2 fitted equation. All other systems studied did not fit. This investigation suggests that geometry hydrocarbons chains an effect on behaviour ammonium salts.
