Isolation of thiophenic compounds by argentation liquid chromatography
Journal Article

· Anal. Chem.; (United States)
A liquid chromatographic method for the isolation of thiophenic compounds from aromatic shale oil fractions is described. Separate one-ring and two-ring aromatic fractions were first obtained by two stages of silica adsorption chromatography. Thiophenic compounds were then separated by class from these fractions by argentation chromatography on a silver nitrate coated silica column. Fractions were examined by capillary gas chromatography with flame ionization and flame photometric detection to follow the sulfur profiles of the enriched eluates. Virtually complete separation was achieved for one ring thiophenes, and benzothiophenes were enriched by about 96% in comparison to naphthalenes. Comparisons are drawn between the method developed and sulfuric acid extraction and sulfoxide/sulfone oxidation.
