摘要
Geting bituminous coal was sequentially extracted with petroleum ether, carbon disulfide, methanol, acetone, and isometric carbon disulfide/acetone mixed solvent at room temperature, affording extracts 1 to 5 (E1 to E5). In total, 77 organooxygen compounds (OOCs) were identified from E3 by gas chromatography/mass spectrometry analysis. The OOCs include 4 alkanols, 8 arenols, 5 ethers, 5 aldehydes, 14 non-nitrogen ketones, 19 nitrogen-containing ketones, 11 alkanoic acids, and 11 esters. This investigation provides an effective approach to the enrichment of OOCs in coals, favoring understanding of the diversity of the organooxygen compounds.
