Photochemistry and absorption cross-sections temperature dependence of trifluoromethoxycarbonyl peroxy nitrate (CF3OC(O)OONO2)

Thermal Decomposition of CxF2x+1C(O)OONO2 (x = 2, 3, 4)

“…Our laboratory has synthesized and characterized many peroxyacyl nitrates. [3][4][5][6][7][8][9][10][11][12][13] In the present article, the focus of the study is set on the thermal stability of the C x F 2x+1 C(O)OONO 2 family (x = 2, 3, 4), formed from the atmospheric degradation of molecules containing the C x F 2x+1 C(O) moiety. These include for example the perfluoroaldehydes, C x F 2x+1 C(O)H, which are formed in the atmospheric degradation of telomeric alcohols, C x F 2x+1 CH 2 CH 2 OH (x = 2, 4).…”

“…They are a reservoir of nitrogen dioxide and peroxy radicals. , In the atmosphere, PANs can be transported from polluted sites to higher altitudes in the troposphere and the tropopause, where the lower temperatures increase their stability, and finally reach remote sites, polluting remote locations. Our laboratory has synthesized and characterized many peroxyacyl nitrates. − …”

“…Moreover, in a dry atmosphere in general, the lifetime of peroxynitrates is controlled by the thermal decomposition in lower altitudes (from surface to approximately 10 km), while photochemical rupture is dominant in higher altitudes. − ,,, This paper presents the determination of thermal stability and the profiles of atmospheric lifetimes for C x F 2 x +1 C­(O)­OONO 2 ( x = 2, 3, 4). It also compares the results with those reported for CF 3 C­(O)­OONO 2 by Zabel et al and Wallington et al in order to determine the effect of the carbon chain length.…”
