Abstract

Twenty one (21) of the twenty eight (28) theoretically possible pentachlorodibenzofurans (p5CDFs) were synthesized and purified. Their retention indices were determined and were found to correlate well to those predicted using a previously developed mathematical model. Gas chromatographic/mass spectrometric (GC/MS) analysis of these compounds revealed that their electron-impact (EI) mass spectra were essentially identical with no significant variations due to positioning of the chlorines. Additional GC/MS experiments indicated that higher electron energies (70 eV as opposed to lower energies) were more suitable for analysis of these compounds due to higher molecular and fragment ion intensities.
