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 (SF6). The only products were nitrogen and perfluoro-2,3-dimethylbutane. The rate constant (k) for the decomposition process is given by: log(k/s-1) = 16.7 ± 0.2 - (9856 ± 109)/T These results lead to a straightforward mechanism for the decomposition process (1) i-C3F7N2 i-C3F7 → i-C3F7N2 + i-C3F7 (2) i-C3F7N2 → i-C3F7 + N2 (3) 2i-C3F7 → (i-C3F7)2 The results are compared with those for other azo compounds.
