Trifluoroperoxyacetic acid oxidation of coal macerals
Maceral concentrates were oxidatively degraded by Trifluoroperoxyacetic Acid (TFPA). The same samples were also oxidized by nitric acid. The results of these studies were checked by applying the same oxidation to high vitrinite and high liptinite coals. These studies were supplemented by TFPA and nitric acid oxidations of model compounds. The TFPA oxidation products were analyzed by NMR. Both TFPA and nitric acid oxidation products were converted to methyl esters and analyzed by gas chromatography and gas chromatography combined with chemical ionization mass spectroscopy. Both helium and methane were used for the chemical ionization. The results of this study confirm the consensus view that vitrinite is related to lignin, liptinite is more aliphatic, and inertinite is close to graphite. Each of these macerals is chemically distinctive.
