Quantitative derivatization of amine-rich isolates of an SRC II heavy distillate coal liquid with trifluoroacetyl or pentafluoropropyl anhydride enabled the selective detection and semiquantitation of fluoroamide derivatives of the amines by capillary column gas chromatography in conjunction with an electron capture detector. Coupled gas chromatography/mass spectrometry and both low- and high-resolution mass spectrometry were used in the identification of the derivatized products and showed the presence of amino polycyclic aromatic hydrocarbons having from two to six rings, some of which were highly alkylated. The presence of amino polycyclic aromatic nitrogen heterocycles (e.g., aminoquinoline) which have not been previously reported in coal liquefaction materials was confirmed by high-resolution mass spectrometry. The advantages of forming the fluoramide derivatives for both the gas chromatographic and mass spectral determination of amino polycyclic aromatic compounds in synthetic fuel materials are demonstrated.
