摘要: Abstract Products of the gas-phase reactions OH radicals (in presence NO) and O3 with biogenic emission cis-3-hexen-1-ol have been investigated using gas chromatography flame ionization detection (GC-FID), combined chromatography-mass spectrometry (GC-MS), Fourier transform infrared spectroscopy (GC-FTIR), direct air sampling, atmospheric pressure tandem mass (API-MS). Propanal 3-hydroxypropanal were identified quantified from radical reactions, respective formation yields 0.746 ± 0.067 0.48−0.24+0.48 reaction 0.493 0.075 0.33−0.16+0.33 reaction. In addition, a hydroxynitrate molecular weight 179 [CH3CH2CH(OH)CH(ONO2)CH2CH2OH and/or CH3CH2CH(ONO2)CH(OH)CH2CH2OH] hydroxycarbonyl 132, expected to be CH3CH2CH(OH)CH(OH)CH2CHO, observed by API-MS analyses. The mechanisms are discussed.
