The field-ionization mass spectral hydrocarbon data from F-45 (Wyodak coal-derived SRC) and F-51 (Kentucky 9/14 coal-derived SRC) were recalculated so the various hydrocarbon fractions could be compared directly on a weight percent basis. A computer program was developed which allows the field-ionization mass spectral hydrocarbon data to be compared in a three dimensional fashion. This approach provides for a rapid general comparson of all the field-ionization hydrocarbon data. The solubility of preasphaltenes was tested in several solvents. The preasphaltenes-2 were found to be largely soluble in pyridine:chloroform 9:1(v/v) or 7:3(v/v) and pyridine:chloroform:tetrahydrofuran 7:1:2(v/v/v). Experiments were carried out in which Chromasorb T was tested as a replacement for Fluoropak in the Fluoropak-basic alumina procedure. The results indicated Chromasorb T would be an adequate substitute for Fluoropak, but additional experiments will be run to confirm this. The chromatographic characteristics of numerous hydroxyl aromatics, nitrogen heterocycles, and aromatic amines were obtained on several normal-phase and reversed-phase high-performance liquid chromatographic systems. 30 references, 30 figures, 10 tables.
