A method is described for the complete separation of the amino polycyclic aromatic hydrocarbons (amino-PAH) from complex coal-derived mixtures. Prefractionation of crude materials is achieved by a previously described two-step alumina/silicic acid adsorption column chromatographic procedure. Next, derivatization with pentafluoropropionic anhydride of the amino-PAH-rich isolate of an SRC II heavy distillate coal liquid enabled the complete separation of this chemical class from other isomeric nitrogen-containing polycyclic aromatic compounds by gel permeation chromatography on Bio-Beads SX-12. Finally, the fluoroamide derivatives were converted back to the orginal amino functionality by catalytic hydrolysis on neutral aluminum oxide. Subsequent high-resolution separation of individual components was achieved by capillary column gas chromatography, and specific compounds were determined by gas chromatographic retention data and gas chromatography/mass spectrometry. Several parent two-, three-, and four-ring amino-PAH, as well as many alkylated homologues, were identified in this complex coal-derived liquid. 6 figures, 3 tables.
