Reactions of hydroxyl radicals with selected hydrocarbons of importance in atmospheric chemistry
1993
The kinetics of the reactions of OH with i-butanol and t-butanol have been studied by laser flash photolysis-laser induced fluorescence (LP-LIF), under pseudo-first-order conditions. The values, k(OH + i-butanol) equals (9.0 +/- 0.9) X 10 -12 cm 3 molecule -1 s -1 and k(OH + t-butanol) equals 1.8 +/- 0.2) X 10 -13 cm 3 molecule -1 s -1 at 292 K were obtained. As a check on the technique measurements were also made of the OH + CH 4 reaction. The value obtained, k(OH + CH 4 ) equals (5.4 +/- 0.2) X 10 -15 cm 3 molecule -1 s -1 at T equals 292 K, is in excellent agreement with the most recent literature value.
