Chemical Oxidation of 5-Amino Quinoline with (NH4)2S2O8: Synthesis and Characterization

5-amino quinoline (AQ) was chemically oxidized in (NH4)2S2O8/HCI system, whose structure was identified by UV-vis, FTIR, 1 HNMR and 13CNMR analysis. Spectral analysis results indicated the formation of phenazine like units in the oxidation product and C3, C6, C8 positions of quinoline ring were suggested as a possible polymerization sites. Size exclusion chromatography indicated the oxidation product (OAQ) consisted of oligomeric units (1200 g/mol). OAQ was thermally stable and half of its mass was decomposed at 1000ºC.
