The general interpretation of field-ionization mass spectral data obtained from eight hydroxyl aromatic oils and asphaltenes fractions was carried out. The field-ionization mass spectral data showed considerable odd mass material in all the fractions indicating nitrogen compounds were present in the fractions. In preasphaltene experiments, elemental analysis data were obtained from nitrogen compound and hydroxyl aromatic fractions from chloroform-soluble preasphaltenes. In addition, work was initiated on the separation of pyridine soluble-chloroform insoluble preasphaltenes. Work was also begun on the separation of nitrogen compounds in oils and asphaltenes into pyridinic-types, carbazolic-types, and amino-types. In other work, a separation method was developed for the compound-class separation of components in oils and asphaltenes using high-performance liquid chromatography. Finally, several manuscripts were written. 1 fig., 3 tabs.
