mog chamber FTIR techniques were used to measure k(Cl + n-C6F13CH2CHO) ) (1.84 ( 0.22) × 10-11,k(Cl + n-C6F13CHO) ) (1.75 ( 0.70) × 10-12, and k(OH + n-C6F13CH2CHO) ) (2.15 ( 0.26) × 10-12 cm3molecule-1 s-1 in 700 Torr of N2 or air diluent at 296 ( 2K. The chlorine-atom-initiated oxidation ofn-C6F13CH2CH2OH in air gives n-C6F13CH2CHO in a molar yield of 99 ( 8%. The atmospheric fateof n-C6F13CH2C(O) radicals is reaction with O2, while the fate of n-C6F13C(O) radicals is decomposition togive n-C6F13 radicals and CO. The results are discussed with respect to the atmospheric chemistry of fluorinatedalcohols and the formation of perfluorocarboxylic acids.
