Flash Photolysis-Time-Resolved UV Spectroscopy of the CF3CFHO2 Self-Reaction

The self-reaction of CF3CFHO2 has been studied via time-resolved ultraviolet spectroscopy over the temperature range 211-372 K.The absorption spectrum of CF3CFHO2 extends from 190 to 275 nm with a maximum cross section of (5.2 +/- 0.3) * 10-18 cm2 molecule-1 at 213 nm.The UV absorbance of the reaction mixture decreases and shifts to the blue as the reaction progresses.This is consistent with the CF3CFHO2 self-reaction producing CF3CFHO, the alkoxy radical then decomposing to yield CF3, which adds molecular oxygen to form CF3O2.The CF3CFHO2 self-reaction has a negative temperature dependence with rate constant given by k1 = (7.8 +/- 1.3) * 10-13 e(605+/-40)/T cm3 s-1.The rate of alkoxy radical dissociation, at 230 Torr of total pressure, is k2a = (3.7 +/- 0.7) * 107 e-(2200+/-150)/T s-1.The rate constants for CF3O2 reaction with CF3CFHO2 and itself are determined to be k8 = (8 +/- 3) * 10-12 and k9 = (1.8 +/- 0.5) * 10-12 cm3 s-1, respectively, at 297 K.

Time-resolved experiments on the atmospheric oxidation of C 2H6 and some C2 hydrofluorocarbons

We report new time-resolved measurements relevant to the atmospheric oxidation of C2H6, CF3CF2H (HFC-125), CF3CH3 (HFC-143a) and CF3CFH 2 (HFC-134a). The radicals R = C2H5, CF 3CF2, CF3CH2 and CF3CFH were produced by photolysis of the corresponding iodides, RI, at 248 nm, using the output from a pulsed excimer laser, in the presence of a large excess of O2 and with different concentrations of NO present. The loss of NO and the formation of the reaction products, CH3C(O)H (from C 2H5 radicals), C(O)F2 and FNO (from CF 3CF2), and C(O)F2 and HFCO (from CF 3CFH) were followed, in real time, via absorption of infrared radiation provided by tuneable diode lasers. Our measurements essentially confirm previous conclusions, based mainly on continuous photolysis experiments, concerning the oxidation mechanisms for these compounds and also how they differ according to whether RO, the ethoxy or substituted ethoxy radical, is formed by mutual reaction of two alkyl peroxy radicals (RO2 + RO 2) or by reaction of one of these radicals with NO (RO2 + NO). In addition, we report rate constants for the important atmospheric reactions of ethyl peroxy with NO at 298 K, and of fluorinated ethyl peroxy radicals with NO, for temperatures between 198 and 298 K.
