The electrochemical adsorption of several cyclic amines: cyclopropylamine, cyclopentylamine, cyclohexylamine, cyclooctylamine and cyclododecylamine on DME from liquid ammoniate of ammonium nitrate was investigated. The basic parameters were evaluated and the structures of adsorption layers were proposed. It was found, that cyclododecylamine has a different orientation on the electrode surface than the other amines.
