✦ Synopsis

The photolysis of perfluoroglutaryl dichloride was investigated in the gas phase with the light of the full arc of a high pressure mercury lamp. At high intensities and conversions the main products are CO and ClCF&F,CF&l, and the ratio CO/Cl(CF,),Cl is 2. However, in runs with attenuated light and very short times, this ratio reaches higher values because less Cl(CFz)sC1 is formed. In the first step the stable intermediate compound ClCO(CF,)&l is formed, producing Cl(CF,),Cl by absorption of a second photon. The thermal decomposition studied in the temperature range 611-713 K produces CO, CF&& , C2F&1,, C,F,, COClz and a very small amount of c-C3F,. A mechanism is suggested to explain these results.
