Resumen:
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, k(OH+ C8F17CH2CHO) = (2.0±0.4) x 10-12, and k(Cl+C8F17CHO) = (1.8 ± 0.9) x 10-12 cm3 molecule-1 s-1 in 700 Torr of N2 or air diluent at 296 K. The results are discussed with respect to the atmospheric chemistry of fluorotelomer alcohols.
