Fate of sulfur functions on oxidation with peroxytrifluoroacetic acid
Hydrogen peroxide in trifluoroacetic acid (peroxytrifluoroacetic acid) is known to rapidly degrade the aromatic portions of molecules leaving the aliphatic skeleton intact. This means of oxidation was found useful in determining the kinds and amounts of organic sulfur functional groups in coal. Aromatic rings directly attached to sulfur in coal survived less than exhaustive oxidation and appeared in the products as sulfones and sulfonic acids. Since the rest of the aromatic structure of coal are completely oxidized, the higher molecular weight portion of the products are compounds enriched in sulfur. These compounds were characterized by gas chromatography, flame photometric and flame ionization detection.
