Tetraethylammonium Perchlorate

The differential capacity of the mercury/solution interface has been measured for various tetraalkylammonium and alkali metal perchlorates in dimethylformamide (DMF) at 25 °C, and for tetraethylammonium perchlorate (TEAP) in DMF at −15 °C, 0 °C, and 40 °C. On the basis of established analyses, it is shown that ionic specific adsorption at mercury from TEAP solutions in DMF is negligible. The properties of the inner layer are analyzed in detail on the basis of a statistical mechanical model in which the solvent molecules represented as hard polarizable spheres can occupy three orientations: with their dipole vectors towards the surface, away from the surface, and parallel to the surface. It is shown that this model provides a reasonable description of the electrostatic properties of the inner layer at the Hg/DMF interface.

The kinetics of the liquid-like → solid-like 2D phase transition of adenine adsorbed at the Hg/aqueous solution interface is studied. Attention is focused on the effect of temperature on the rate of phase change; an increase in temperature is found to cause a decrease of transition rate.
