Kinetic study of the gas‐phase reaction of hydroxyl radical with CF₃CH₂OCH₂CF₃ using the laser photolysis–laser induced fluorescence method

Abstract

The laser photolysis-laser-induced fluorescence method was used for measuring the kinetic parameters of the reaction of OH radicals with CF 3 CH 2 OCH 2 CF 3 (2,2,2-trifluoroethyl ether), in the temperature range of 298-365 K. The bimolecular rate coefficient at 298 K, k I I (298), was measured to be (1.47 ± 0.03) × 10 −13 cm 3 molecule −1 s −1 , and the temperature dependence of k I I was determined to be (4.5 ± 0.8) × 10 −12 exp[−(1030 ± 60)/T] cm 3 molecule −1 s −1 . The error quoted is 1σ of the linear regression of the respective plots. The rate coefficient at room temperature is very close to the average of the three previous measurements, whereas the values of E a /R and the A-factor are higher than the two previously reported values.
