Kinetics of the gas-phase reactions of some unsaturated alcohols with Cl atoms and O3

Reactions of Cl atoms with 3-buten-1-ol, 3-methyl-3-buten-1-ol, 2-methyl-3-buten-1-ol and 4-penten-2-ol were investigated using relative technique with gas chromatograph coupled with flame ionization detection (GC-FID). At 298 ± 1 K and 1.01 × 105 Pa, the rate coefficients measured (in units of 10−10 cm3 molecule−1 s−1) were 3.63 ± 0.49, 4.13 ± 0.56, 3.51 ± 0.48, and 3.62 ± 0.49, respectively. The quoted errors included 2σ from the least-squares analysis and also 10% errors caused by the uncertainty of the reference rate coefficients. In addition, rate coefficients for reactions of the unsaturated alcohols with O3 were determined using absolute method. The values obtained have been presented, compared with those of their alkene structural homologues and discussed. Reactivity trends and atmospheric implications have also been discussed.
