Abstract Абсолютные константы скорости реакций трифторметильного радикала с фтором (I) и кислородом (II) k1=(3,1±2,1)·10−11 exp[−(4600±300)/RT] (cm3/молек. сек), k2=(2,5±1,7)·10−11 exp[−(2100±300)/RT] (cm3/молек. сек) определены на основании полученното при фотолизе смеси гексафторццетона с кислородом и хлором отношения констант скорости реакций трифторметильного радикала с O2 и Cl2 (ІУ) k2/k4=(3,6±1,6)exp[(1600±300)/RT](T=296–356° K).

Abstract The absolute rate constants for the reactions of trifluoromethyl radicals with fluorine (I) and oxygen (II), k1=(3.1±2.1)×10−11 exp [−(4600±300)/RT] (cm3/molec sec) and k2=(2.5±1.7)×10−11 exp [−(2100±300)/RT] (cm3/molec sec). have been determined from the relative rate constants for the reactions of trifluoromethyl radicals with oxygen and chlorine (IV):k2/k4=(3.6±1.6)exp [(1600±300)/RT] (T=269–356 K) obtained by the photolysis of a mixture of hexafluoroacetone (HFA) with O2 and Cl2.
