The gas‐phase thermal isomerization of hexachlorocyclopropane to hexachloropropene at 208–283°C is first order and unaffected by changes in the surface‐to‐volume ratio or by the addition of iodine, tetrachloroethylene, and oxygen. The first‐order rate constants fit the Arrhenius equation\documentclass{article}\pagestyle{empty}\begin{document}$${\rm log}k({\rm s}^{ - 1}) = (15.74 \pm .022) - (45,660 \pm 526)/4.576T$$\end{document}The reaction was interpreted as an unimolecular process taking place with chlorine atom migration. A comparison of the reactivities of several chlorocyclopropanes is made.
