Lean post flame oxidation is used as an environment to examine the des
truction and byproduct formation of CH2 Cl-2. These conditions are sim
ilar to poor operating conditions that may occur in hazardous waste co
mbustors, where unconsumed CHCs escape the primary flame zone and reac
t in the cooler post-flame region. The main byproduct for the injected
compound was COCl2. CH2Cl2 also produced C2HCl3 and cis and trans 1,
2-C2H2Cl2. The comparison of these results with data from previously r
eported flowreactor studies at pyrolytic and at oxidative pyrolytic co
nditions show significant differences in the concentration of the bypr
oducts. The main reaction routes for the destruction of the injected C
H2Cl2 and for the formation of the detected byproducts are discussed.
