Abstract

The kinetics of the gas‐phase thermal isomerization between trans‐ and cis‐1,2‐bis(trifluoromethyl)‐1,2,3,3‐tetrafluorocyclopropane as well as their decomposition to trans‐ and cis‐perfluoro‐2‐butene, respectively, and CF~2~, was studied in the temperature range of 473–533°K, with an initial pressure of reactant of 1.5 to 7.0 Torr. Some runs were also made with the addition of SF~6~ as an inert gas up to a total pressure of 100 Torr. The reactions are first order and homogeneous. The rate constants for the geometrical isomerization fit the following Arrhenius relations:

and the corresponding equations for the decomposition of the trans and cis‐cyclopropane are
