摘要：

The products of the chlorine atom initiated oxidation of different unsaturated alcohols were determined at atmospheric pressure and ambient temperature, in a 400 L teflon reaction chamber using GC-FID and GC-MS for the analysis. The major products detected (with molar yields in brackets) are: chloroacetaldehyde (50 +/- 8%) and acrolein (27 +/- 2%) from allyl alcohol; acetaldehyde (77 +/- 11%), chloroacetaldehyde (75 +/- 18%), and methyl vinyl ketone (17 +/- 2%) from 3-buten-2-ol; acetone (55 +/- 4%) and chloroacetaldehyde (59 +/- 8%) from 2-methyl-3-buten-2-ol; chloroacetone (18 +/- 1%) and methacrolein (8 +/- 1%) from 2-methyl-2-propen-1-ol; acetaldehyde (20 +/- 1%), crotonaldehyde (6 +/- 3%), 3-choloro-4hydroxy-2-butanone (2 +/- 2%) and 2-chloro-propanal (4 +/- 5%) from crotyl alcohol; and acetone (24 +/- 3%) from 3-methyl-2-buten-1-ol. The experimental data suggests that addition of Cl to the double bond of the unsaturated alcohol is the dominant reaction pathway compared to the H-abstraction channel. (C) 2011 Elsevier Ltd.
