The reaction of C2F5 radicals with H2S

Abstract

AbstractThe reaction of C2F5 radicals with H2S was studied over the range 1°−123°C using C2F5 radicals generated by photolysis of perfluoropropionic anhydride. The rate constant kH for reaction (2) is given by where θ = 2.303RT/cal mole−1. The relevance of this result to conflicting published data on the analogous reaction between CF3 radicals and H2S is discussed. It is concluded that there is little difference in the Arrhenius parameters for reaction of CF3 and C2F5 radicals with H2S.
