Thermal decomposition of Δ1-3,3,4,4-tetrafluorodiazetidine

Abstract

The gas phase thermal decomposition of Δ¹-3,3,4,4-tetrafluorodiazetidine has been studied over the temperature range 120–160°C and at initial pressures of 5–150 Torr. The decomposition was found to be a homogeneous unimolecular process, yielding nitrogen and tetrafluoroethylene. The k_∞ values were obtained from plots of 1/k_p against 1/P^½ and fit the following Arrhenius equation k_∞/s^–1= 10^{16.40 ± 0.13} exp(–38 950 ± 250 cal mol^–1/RT)

The A factor for the decomposition is discussed in terms of different transition states.
