✦ Synopsis

Measurements of condensed-phase products of trichloroethylene (C2HC13) pyrolysis in a drop-tube reactor were obtained over a temperature range of 1100-1500 K. A predominance of perchloroaromatics was found, in sharp contrast to the largely unsubstituted polycyclic aromatic hydrocarbons obtained from the pyrolysis of a mixture of C2HCI 3 and toluene under similar conditions. A second major difference in the products of these fuels was the much lower carbon number distribution in the pure C 2 HCI 3 pyrolysis tars (ranging from C 4 to C 14), indicative of a significantly reduced rate of carbon growth in the highly chlorinated system. The perchloroaromatic-containing pyrolysis tars were not found to be active using the S. typhimurium cell mutation assay in the presence of enzymes that simulate metabolism, whereas the C2HCI 3/toluene high-temperature pyrolysis tars were strongly mutagenic.
