Formation, thermal decomposition and atmospheric implications of the CF2(OH)CF2OONO2 and CF3CF2OONO2 peroxynitrates. A theoretical study
(Elsevier Science, 2017-02)
A SACM/CT study of the CF2(OH)CF2OO + NO2 → CF2(OH)CF2OONO2 and CF3CF2OO + NO2 → CF3CF2OONO2 recombination reactions and their reverse unimolecular decomposition process was performed. The electronic energy along the ...
A new perfluorinated peroxynitrate, CF3CF2CF2CF2OONO2. Synthesis,characterization and atmospheric implications
(Elsevier Science, 2014-09)
CF3CF2CF2CF2OONO2was synthesized from the photolysis of CF3CF2CF2CF2I, in presence of NO2and O2.Alkyl peroxynitrates (CxF2x+1OONO2) could be formed in the atmospheric degradation of chlorofluorocar-bons, hydrofluorocarbons ...
Quantum chemical characterization of the CF2(OH)CF2OONO2 and CF3CF2OONO2 peroxynitrates and related radicals
(Elsevier, 2015-04)
We present a detailed study of the molecular conformations, vibrational spectra and thermochemistry of the CF2(OH)CF2OONO2 and CF3CF2OONO2 peroxynitrates. In addition, we studied the CF2(OH)CF2OO, CF2(OH)CF2O, CF3CF2OO and ...
Theoretical modeling study of the reaction H + CF4 → HF + CF3
(John Wiley & Sons Inc., 2021-08)
The high-temperature hydrogenation of CF4 in mixtures of CF4 and H2 is assumed to involve the reaction H + CF4 → HF + CF3. The hydrogen atoms here are either formed by the reaction of F and CF3 (i.e., the products of the ...
Mechanism of photo-oxidation of heptafluorobutyric anhydride in the presence of NO2. Synthesis and characterization of heptafluoropropyl peroxynitrate, CF3CF2CF2OONO2
(American Chemical Society, 2012-10)
The photolysis of heptafluorobutyric anhydride at 254 nm in the presence of NO2 and O2 has been studied. It leads to the formation of CF3CF2CF2OONO2, CF 3CF2OONO2, and CF2O as the only fluorine-containing carbonaceous ...
Relative rate coefficients of OH radical reactions with CF3CFCClCF3 and CF3CHCHCH2OH. Ozone depletion potential estimate for CF3CFCClCF3
(Pergamon-Elsevier Science Ltd, 2013-03)
The relative rate method was used to determine the rate coefficients for the reactions of OH radicals with CF3CFCClCF3 (k1) and CF3CHCHCH2OH (k2). Experiments were carried out at (298 ± 2) K and atmospheric pressure using ...
