Mechanism of the pyrolysis of 1,2‐dichloroethane in the absence and presence of added chlorine

A detailed radical reaction model, both homogeneous and heterogeneous, is shown to describe quantitatively published initial rates of the pyrolysis of 1,2‐dichloroethane in the gas phase. These data were obtained in conditioned static reactors with different surface‐to‐volume ratios, in the absence (at 703 K) and presence (at 572 K) of chlorine. The pressures of 1,2‐dichloroethane and chlorine vary from 20 to 500 torr and from 0 to 16 torr, respectively.
