The field-ionization mass spectral results have been obtained on eight hydroxyl aromatic fractions from Wyodak coal-derived SRC(F-45) and Kentucky 9/14 coal-derived SRC(F-51). Several experiments were carried out on preasphaltenes-1. It was shown that this material could be separated into a nitrogen fraction and a hydroxyl aromatic fraction. Other experiments with preasphaltenes-1 indicated that direct injection of the material onto a silica gel column gave anomalous results. Several binary and ternary solvents were found to solubilize preasphaltenes-2 from F-51. These solvents dissolved most of the preasphaltenes-2 from F-45. It may not be possible to obtain enough hydroxy aromatic material from reversed-phased chromatography for field-ionization mass spectral analysis. However, normal-phase chromatography for field-ionization mass spectral analysis. However, normal-phase chromatography can be used for this purpose. Encouraging results have been obtained with silica gel and dimethyl sulfoxide:carbon tetrachloride mobile phases for the compound class separation of polycyclic aromatic hydrocarbons, nitrogen compounds, and hydroxyl aromatics. 11 figures, 4 tables.
