The field-ionization mass spectral data were received for six hydroxyl aromatic and nitrogen compound fractions, and the data are being interpreted. Field-ionization mass spectral data for polycyclic aromatic hydrocarbons in the nitrogen fractions from oils and asphaltenes were interpreted in considerable detail. Several compositional characteristics of the polycyclic aromatic hydrocarbons have been described. The main causes for the low volatility, low carbon content, and high ash for some of the fractions isolated by the silica gel-dimethyl sulfoxide:carbon tetrachloride chromatographic system have been explained. Relatively high metal content of silica gel and high percentages of chlorine and sulfur in the fractions were identified as problems. Finally, three manuscripts are being revised and one manuscript is in review. 4 refs., 6 figs., 3 tabs.
