The thermal dehydrochlorination CCl 2 FCH 3 → CClFCH 2 + HCl has been studied in a static system between 610 and 700 K at pressures ranging from 14 to 120 torr. The experiments were performed in the absence and presence of an added inhibitor (0.5 to 7 torr of C 3 H 6 ) or catalyst (2 to 8 torr of CCl 4 ). The evolution of the reaction was followed by measuring the pressure rise in the quartz reaction vessel and analyzing the products by gas chromatography. All the experimental results can be explained quantitatively in terms of a reaction model both radical and molecular. The molecular dehydrochlorination has an activation energy of 57.05 kcal/mol and a preexponential factor of 10 14.02 s −1 . © 2001 John Wiley & Sons, Inc. Int J Chem Kinet 33: 191–197, 2001
