Influence of solvent structure on ion pair association: The conductance of potassium perchlorate in ethylene carbonate-acetonitrile mixtures at 25°C
TLDR
In this paper, the conductance of potassium perchlorate in mixtures of ethylene carbonate and acetonitrile covering the range 82.6 ≥ D ≥ 36.0 in dielectric constant has been measured.Abstract:
The conductance of potassium perchlorate in mixtures of ethylene carbonate and acetonitrile covering the range 82.6 ≥ D ≥ 36.0 in dielectric constant has been measured. The Walden products in these aprotic solvents are approximately one-half as large as the products for the same salt in isodielectric mixtures of water and tetramethylene sulfone. This alters the distribution between electrostatic and hydrodynamic terms in the theoretical conductance function in such a way that the calculated association constants for potassium perchlorate are much smaller in the aprotic mixtures.read more

Molecular association and dynamics in n-pentanol and 2-methyl-2-butanol
TL;DR: In this paper, the activation energies obtained from dielectric and ultrasonic studies are compared with those obtained from viscous flow, and it is shown that in n-pentanol and 2-methyl-2-butanol, a correlation between viscosity and ultra-frequency relaxation exists.
