Development of coal upgrading processes such as gasification and liquefaction must be continued because of the long-term uncertainty in the availability of petroleum resources. Identification of components and investigation of the environmental effects of coal-derived products produced in these upgrading processes are required. Although numerous studies describing the identification and characterization of polycyclic aromatic hydrocarbons (PAH) and polycyclic aromatic compounds (PAC) containing a single heteroatom have been reported, PAC containing more than one heteroatom have been only tentatively identified until recently. In the last year, many new PAC containing two heteroatoms in a solvent-refined coal liquid were positively identified using capillary column gas chromatography. These compounds include hydroxylated thiophenic compounds, aminodibenzothiophenes, hydroxylated nitrogen heterocycles, azathiophenic compounds, and amino-substituted nitrogen heterocycles. In this paper, the analytical methods for the identification of trace amounts of PAC containing two heteroatoms in complex coal-derived materials are reviewed. The structural characteristics of the PAC formed in a solvent-refined coal liquid and a coal tar were compared, and standard compounds were synthesized for verification of identifications and for mutagenicity testing.
