Synthesis and pyrolysis of perfluoroazo‐2‐propane

An improved method has been used to synthesize perfluoroazo‐2‐propane. Pyrolysis over the temperature range 450–514 K in a static system has been shown to be a homogeneous, first‐order process. No pressure dependence was observed in the presence of excess inert gas (SF 6 ). The only products were nitrogen and perfluoro‐2,3‐dimethylbutane. The rate constant ( k ) for the decomposition process is given by:\documentclass{article}\pagestyle{empty}\begin{document}$$ \log \left({{k \mathord{\left/{\vphantom {k s}} \right. \kern-\nulldelimiterspace} s}^{- 1}} \right) = 16.7 \pm 0.2 - {{\left({9856 \pm 109} \right)} \mathord{\left/{\vphantom {{\left({9856 \pm 109} \right)} T}} \right. \kern-\nulldelimiterspace} T} $$\end{document}These results lead to a straightforward mechanism for the decomposition processThe results are compared with those for other azo compounds. © 1994 John Wiley & Sons, Inc.
