Abstract
The thermal decomposition of SF5O3SF5 in the presence of CO has been investigated between ‐9.8°C and + 9.9°C. Besides traces of S2F10, equimolecular amounts of SF5O2SF5 and CO2 are formed. The reaction is homogeneous. Its rate is proportional to the pressure of the trioxide and in dependent of the total pressure, the pressure of inert gases and of carbon monoxide: where k = k1∞ = 1016.32±0.40 exp(−25,300 ± 500 cal)/RT sec−1. Consequently, In the presence of oxygen a sensitized CO2 formation is observed. A mechanism is given which explains the experimental results.Keywords
