The thermal dehydrochlorination CF 2 ClCH 3 →CF 2 (DOUBLEBOND)CH 2 +HCl has been studied in a static system between 597 and 664 K in the presence of CCl 4 , C 2 Cl 6 , CF 2 (DOUBLEBOND)CH 2 , HCl, and CF 3 CH 3 . A kinetic radical and molecular reaction model has been developed. In addition to describing earlier results on the acceleration of the pyrolysis by CCl 4 and the further acceleration by HCl, this model describes quantitatively up to conversions of 20% (i) the dependence of the catalytic effect of CCl 4 at low concentrations, (ii) the stronger catalytic effect of C 2 Cl 6 , and (iii) the inhibitory effect of added CF 2 CH 2 and CF 3 CH 3 when CCl 4 is used as a catalyst. © 1998 John Wiley & Sons, Inc.
