Ionic mobility and dielectric relaxation in supercooled liquid KCl-glycerol solutions

“…Secondly, we note that our values of Walden product increase as the temperature is lowered and the viscosity increased. This is in qualitative agreement with other experiments, reviewed on p. 546 of [28] and on p. 645 of [26], in which the viscosity of a solution has been increased by the addition of a second solvent. The situation in glycerol is simpler since only one pure solvent is used throughout and complications due to differing solute-solvent solvation effects are avoided.…”

Non-steady-state kinetic study of the SN2 reaction between p-nitrophenoxide ion and methyl iodide in acetonitrile

“…The kinetic data in Table 1 were obtained using tetrabutylammonium p-nitrophenoxide with and without added NaPF 6 , both of which are expected to be completely dissociated in acetonitrile. 4 The results of these experiments support our earlier work 2 indicating that k init /k pfo (the ratio of pseudo first-order rate constants measured in the extent of reaction range from 0 to 0.05 and 0.05 to 0.50, respectively) is significantly greater than unity and suggests that Na ϩ acts as a spectator ion under these conditions. No water was intentionally added to these solutions.…”

The conductance behaviour of NaBPh4 in acetonitrile–toluene mixtures at 15,25, and 35 °C

“…The experimental results have been analysed according to the method of Pethybridge and Taba (5) who use the Lee-Wheaton conductance equation (6,7). This equation is different from the previous conductance equations, most of which are based on the "primitive" model (8).…”
