Abstract
Rate constants determined for the thermal dimerization of chlorotrifluoroethene to dichlorohexafluorocyclobutane at 404β672 K have been correlated with previously published results. For the temperature range of 404β800 K,
The dependence of the preexponential factor on temperature corresponds to a value of 17 J/KΒ·mol for the difference in heat capacity (Ξ__C__~p~^Β±^) between the activation complex and the reactant.

The reversible thermal gas-phase dimerization of hexafluoropropene to the four isomeric cyclobutanes has been studied by pressure change and by gasliquid chromatographic analysis in the temperature range of 645-708 K with initial pressures of olefin from 802 to 4820 mm Hg. The reaction was accuratel
