摘要：
The atmospheric chemistry of CF3(CF2)(7)H was studied in an 11.5-dm(3) environmental reaction chamber by means of Fourier transform infrared spectroscopy. Using a relative rate method, we determined the Arrhenius expression for the rate constant of the reaction of CF3(CF2)(7)H with OH radicals to be (4.32 +/- 1.87) x 10(-13) exp[-(1540 +/- 130)/T] cm(3) molecule(-1) s(-1) at 253-328 K. At 298 K, COF2 was a sole product in a molar yield of (1.02 +/- 0.11) in terms of carbon. (C) 2010 Elsevier B. V. All rights reserved.
