摘要：
Smog chamber/FTIR techniques were used to measure a 92 +/- 7% yield of C8F17CH2CHO in the chlorine atom initiated oxidation of C8F17CH2CH2OH ( 8: 2 FTOH) in 700 Torr of air. Relative rate techniques were used to measure k(Cl + C8F17CH2CHO) = (1.9 +/- 0.4) x 10 (11) and k(OH + C8F17CH2CHO) = (2.0 +/- 0.4) x 10 (12) cm(3) molecule (1) s (1) in 700 Torr of N-2 or air diluent at 296 K. The results are discussed with respect to the atmospheric chemistry of fluorotelomer alcohols. (C) 2008 Elsevier B.V. All rights reserved.
