The electroreduction of 1-nitropentane in the absence and in the presence of 1-octanol was studied. In the absence of inhibitor, 1-nitropentane at concentrations near to saturation is adsorbed weakly on mercury electrodes. In the presence of smaller concentrations of inhibitors, such as 1-octanol, 1-nitropentane electroreduction is inhibited less than that of nitromethane under comparable conditions. This difference was explained by the larger affinity of 1-nitropentane to the alcohol-rich surface phase and nitromethane to the aqueous solution phase. The increased affinity of the reactant to the electrode surface phase at the 1-octanol relative concentration, c/cs, exceeding 0.7, may explain the independence of the electroreduction rate constant of 1-nitropentane and, even, its increase when the bulk concentration of inhibitor approached the saturation.
