Abstract

The hydrogen abstraction reactions of CF3 radicals with CF3COOH and CF3COOD

CF3 + CF3COOH → CF3H + CF3COO                 (1)

CF3 + CF3COOD → CF3D + CF3COO                 (2)

have been studied in the temperature ranges 102-225°C and 153-275°C respectively. The rate constants, based on the value of 1013.36 cm3 mol-1 s-1 for the recombination of CF3 radicals, are given by (k in cm3 mol-1 s-1 and E in J mol-1):

logk1 = (10.17±0.12)-(33140±970)/19.145T                     

logk2 = (9.51±0.11)-(46090±1010)/19.145T
