LASER-DRIVEN OXIDATION OF SOME HALOOLEFINS
Pola, J.,Chvatal, Z.
, p. 197 - 214 (1987)
CW CO2 laser-photosensitized (SF6) oxidation of hexafluoropropene, chlorotrifluoroethene, 1,1-dichlorodifluoroethene, 1,2-dichlorodifluoroethene and hexafluoro-1,3-butadiene with molecular oxygen at total pressure 13-26.5 kPa leads with all but the last to the formation of carbonyl halides.The distribution of these products suggests that the oxidation occurs via a cleavage of intermediary dioxetanes.The reactivities of the olefins towards oxygen at mean effective temperature 710 K are nearly equal.
Atmospheric Cryochemistry: Oxygen Atom Reaction with Fluorocarbon Freon 11 in Matrices. FTIR Spectra of Isolated COFCl and COFCl:Cl2 Complex in Solid Argon
Schriver, L.,Abdelaoui, O.,Schriver, A.
, p. 8069 - 8073 (1992)
Fourier transform infrared spectroscopy has been employed to investigate the reaction of CFCl3 (Freon 11) with atomic oxygen in argon and oxygen matrices at 12 K.Ozone was employed as a photolytic oxygen atom source.The results indicate that the only primary reaction product is COFCl when the oxygen atom is in an excited state.No intermediate was observed.Upon thermal annealing after photolysis, diffusion through the matrix leads to the efficient formation of COFCl:Cl2 aggregates.The spectra obtained after irradiation in various experimental series (isotopic ozone, wavelength dependence, product growth curves) are analyzed and have been interpreted from vibrational spectra of normal and isotopically substituted COFCl isolated in argon and from vibrational spectra of their molecular complexes with Cl2 embedded in argon.Fermi resonance doublets in the νC=O stretching region are observed mainly for the C18OFCl species and the C16OFCl...Cl2 complex
Time-Resolved Observation of the Formation of CF2O and CFClO in the CF2Cl + O2 and CFCl2 + O2 Reactions. The Unimolecular Elimination of Cl Atoms from CF2ClO and CFCl2O Radicals
Wu, Fuxiang,Carr, Robert W.
, p. 1743 - 1748 (1992)
The unimolecular elimination of chlorine atoms from CF2ClO and CFCl2O radicals has been observed at 238 and 298 K and at 4-20 Torr total pressure by measurement of the rate of formation of the carbonyl halide product in real time.The fragment ion (CFO)+ w

Page/Page column 2-3, (2008/06/13)
The invention pertains to a process for preparing chlorodifluoroacetyl fluoride (CDAF) by oxidation of chlorotrifluoroethylene (CTFE) in a solvent using a continuously stirred tank reactor. It provides a process for the production of chlorodifluoroacetyl fluoride by comprises reacting a solvent solution of chlorotrifluoroethylene with oxygen in a reactor to form a product which comprises chlorodifluoroacetyl fluoride. The reacting may be conducted in a continuous or batch mode.
