PREDICTION OF THE CARCINOGENIC ACTIVITY OF TWO LARGE PAH PRODUCED FROM THE SUPERCRITICAL PYROLYSIS OF SYNTHETIC JET FUEL S-8

摘要

In previous work, using high performance liquid chromatography with diode-array ultraviolet-visible (UV) absorbance and mass spectrometric detection, we have reported the identifications of dibenzo[b,ghi]perylene and benzo[cd]naphtho[1,2,3-lm]perylene from the supercritical pyrolysis of synthetic jet fuel S-8. Because polycyclic aromatic hydrocarbons (PAH) are carcinogenic or mutagenic, PAH formation during fuel combustion is of concern for both health and environmental motivations. Due to the well-known link between the carcinogenic potential of a compound, e.g., PAH, and its electronic distribution, the method proposed here uses as basis the analysis of the UV absorption spectrum, i.e., the graphical representation of the electronic distribution inside of PAH.
