摘要：

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 x 10(5) Pa, the rate coefficients measured (in units of 10(-10) cm(3) 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 2 sigma 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 O-3 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.
