Liquid ammoniates (LA) in comparison with other non-aqueous solutions were relatively rarely used in electrochemical investigations although they are good solvents for numerous organic and inorganic compounds. LA\’s are good medium for electrochemical investigations. The range of available potentials for electrochemical investigations of LA\’s is 0-1.4V (vs. SEC). The oxygen wave does not occur on the liquid ammoniates voltamperometric curves. The boiling point of solvents obtained under atmospheric pressure is usually higher than 293K, which proves the existence of considerable interaction forces between the salt and ammonia molecules. So one must use neither cooling nor pressure vessels when working with ammoniates.
The solutions of penthyloamine isomers in liquid ammoniate of ammonium nitrate (LAAN) were investigated. The aim of the work was the determination of the excess adsorption isotherms and the calculation of essential values describing the adsorption and coadsorption process on the dropping mercury electrode.
