Thin-layer chromatography (TLC) has been applied to the chemical class fractionation of shale oil. The chromatographic procedure gives rapid and reproducible separation of the oil into 14 fractions, without requiring prior extraction of asphaltenes, acids, or bases. The oil was adsorbed on silica-coated TLC plates and eluted with n-pentane and n-pentane/diethyl ether to separate the nonpolar and polar components, respectively. The principal compound types resolved included n-alkanes, alkenes, mono-, hydro-, di-, and polyaromatics, nitriles and ketones, hydroxyl aromatic hydrocarbons, and nitrogen heterocyctes. Compound identification was by gas chromatography/mass spectroscopy supplemented by ir spectrometry. The method significantly decreases the analysis time required for chemical class fractionation. 33 references, 4 figures, 1 table.
