POLAROGRAPHIC STUDY OF NITRATE ESTERS. I. REDUCTION OF PENTAERYTHRITOL MONONITRATE
Abstract
The polarographic reduction of pentaerythritol mononitrate in unbuffered aqueous solution of pH 1-4, gave two well defined waves which are shown to be diffusion controlled. From examination of the wave equation the electrode processes in each case are found to be irreversible. The first wave, not pH dependent, has a mean half wave potential, E1/2 = -0.439 volt and is assigned to the electrode reduction of the nitrate function, through a two- electron change. The second wave which appears at a more negative potential, approximately -1.0 volt, is pH dependent and is shown to arise from the reduction of nitrous acid through a four electron change. This wave disappears at pH's above 4. In buffered solutions under acidic conditions the first wave has a mean half wave potential, E1/2 = -0.416 volt. Under basic conditions, however, E1/2 shifts to more negative values. This shift in E1/2 is interpreted as arising from complex formation of pentaerythritol mononitrate and the borate anion of the buffering system.
