Polyaromatic hydrocarbons in high-boiling petroleum distillates. Isolation by gel permeation chromatography and identification by fluorescence spectrometry.
Anal Chem 1973 Jun; 45(7):1050-1055
The identification of seven polyaromatic ring systems in petroleum is reported. The ring systems are 1.12,2.3-Dibenzoperylene; 1, 12-o- phenyleneperylene, pyreno-[1.3:10'.2']pyrene; 2.3, 10.11- Dibenzoperylene; 1, 2, 4, 5-dibenzopyrene, benzo[e]pyrene, and benzo[g]chrysene. These polyaromatic hydrocarbons were isolated by a separation scheme involving ion exchange chromatography, gel permeation chromatography, and thin-layer chromatography and were identified by fluorescence spectroscopy. Gel permeation chromatography separated pericondensed aromatic ring systems from catacondensed ring systems and the other components of an acid concentrate.
