چکیده
Long path length FTIR-smog chamber techniques were used to determine k(Cl + CF3CF@CH2) = (7.03 ± 0.59) · 10 , k(OH + CF3CF@CH2) = (1.05 ± 0.17) · 10 , and k(O3 + CF3CF@CH2) = (2.77 ± 0.21) · 10 21 cm molecule 1 s 1 in 700 Torr of N2, N2/O2, or air diluent at 296 K. CF3CF@CH2 has an atmospheric lifetime of approximately 11 days and a global warming potential (100 yr time horizon) of four. CF3CF@CH2 has a negligible global warming potential and will not make any significant contribution to radiative forcing of climate change. 2007 Elsevier B.V. All rights reserved.

متن کاملSelected ion flow tube study of the gas-phase reactions of CF+, CF2+, CF3+, and C2F4+ with C2H4, C2H3F, CH2CF2, and C2HF3.
We study how the degree of fluorine substitution for hydrogen atoms in ethene affects its reactivity in the gas phase. The reactions of a series of small fluorocarbon cations (CF(+), CF(2)(+), CF(3)(+), and C(2)F(4)(+)) with ethene (C(2)H(4)), monofluoroethene (C(2)H(3)F), 1,1-difluoroethene (CH(2)CF(2)), and trifluoroethene (C(2)HF(3)) have been studied in a selected ion flow tube. Rate coeffi...
متن کاملTheoretical Kinetic and Mechanistic Studies on the Reactions of CF₃CBrCH₂ (2-BTP) with OH and H Radicals.
CF₃CBrCH₂ (2-bromo-3,3,3-trifluoropropene, 2-BTP) is a potential replacement for CF₃Br; however, it shows conflicted inhibition and enhancement behaviors under different combustion conditions. To better understand the combustion chemistry of 2-BTP, a theoretical study has been performed on its reactions with OH and H radicals. Potential energy surfaces were exhaustively explored by using B3LYP/...
متن کاملA comparison of methods for measuring relative radical stabilities of carbon-centred radicals.
This article discusses and compares various methods for defining and measuring radical stability, including the familiar radical stabilization energy (RSE), along with some lesser-known alternatives based on corrected carbon-carbon bond energies, and more direct measures of the extent of radical delocalisation. As part of this work, a large set of R-H, R-CH(3), R-Cl and R-R BDEs (R = CH(2)X, CH...
