✦ Synopsis

Chemical structures of atmospheric-pressure, fuel-rich (sooting), premixed, laminar flames of 1,2-C2H4C12 and CH 4 have been investigated using a flat-flame burner. Species mole fraction profiles were determined by using a hot-water-cooled micro-probe coupled to an on-line gas chromatograph/mass spectrometer. In addition to those of the reactants, mole fraction profiles have been determined for CO, CO2, HC1, H20 , H2, C2I-I6, C2H4, C2H2, CH3CI , C2HaCI, C4H,,, C4H2, and C6H 6. In a stoichiometric flame of pure 1,2-C2H4C12, highly chlorinated hydrocarbons such as C2C14, C2HC13, trans-C2H2C12, C2HCI, CC14, and CHC13, as well as C12 and COC12, were also observed. The roles of these species, in view of the current ideas of the mechanism of combustion of 1,2-C2H4C12, are discussed.
