Реферат: Comparative studies of catalytic hydrogen evolution from pyridine and N-methylpyridinium buffer solutions with the use of I-t curves demonstrate that the process is catalysed not by the pyridine itself but by its electroreduction product. Therefore a scheme with the regeneration of the starting pyridine for determining the rate constants of the organic base protonation and bimolecular interaction of the free radicals from the polarographic catalytic hydrogen currents is inapplicable. It is proposed that the process be described by a scheme incorporating a stage of the formation of a dimer and/or organometallic compound of the “organic calomel” or amalgam type.
