•Two organic fluorines were identified in a Chinese anthracite using mass spectrometry.•Fingerprint of heteroatom-containing compounds was characterized.•Higher polarity of acetone at supercritical state may induce a higher degree of decomposition of the anthracite.
The products in the water-soluble portion from mild oxidation of Jincheng No. 15 anthracite in aqueous hydrogen peroxide were analyzed with a gas chromatograph/quadrupole time-of-flight-mass spectrometer (GC/QTOF-MS) along with theoretical calculation for the first time. A series of heteroatom(s)-containing components were identified by comparing their mass spectra with NIST11 library data. Moreover,...
