“…2. The finding could be attributed to the presence of the methyl tetrols in the gas phase based on estimated saturation vapor pressures for tetrols reported by Angove et al (2006). However, it is also possible that, given the sampling flows used, a small amount of the aerosol, especially at small aerosol diameters, diffused to the denuder surface.…”

“…The disproportionation reactions to form the 2-methyl tetrols are analogous to reactions proposed by Angove et al (2006) to explain the formation of d+l-threitol and mesoerythritol in the aerosol phase during the photooxidation of 1,3-butadiene. In terms of the RO 2 +RO 2 reactions, the major difference between isoprene and 1,3-butadiene is the presence of a tertiary carbon in isoprene which can influence the rate constant for the process involving tertiary radicals.…”

“…In terms of the RO 2 +RO 2 reactions, the major difference between isoprene and 1,3-butadiene is the presence of a tertiary carbon in isoprene which can influence the rate constant for the process involving tertiary radicals. Angove et al (2006) detected the tetrols in NO x experiments but after the time when NO would have been removed by reaction. Assuming the 2-methyl tetrols and tetrols form in the isoprene and 1,3-butadiene systems, respectively, partitioning from the gas to particle phase might be expected to be highly efficient, leading to the compounds being detected in the particle phase.…”

Abstract. The reaction of isoprene (C 5 H 8 ) with hydroxyl radicals has been studied in the absence of nitrogen oxides (NO x ) to determine physical and chemical characteristics of the secondary organic aerosol formed. Experiments were conducted using a smog chamber operated in a steady-state mode permitting measurements of moderately low aerosol levels. GC-MS analysis was conducted to measure methyl butenediols in the gas phase and polyols in the aerosol phase. Analyses were made to obtain several bulk aerosol parameters from the reaction including values for the organic mass to organic carbon ratio, the effective enthalpy of vaporization ( H eff vap ), organic peroxide fraction, and the aerosol yield. The gas phase analysis showed the presence of methacrolein, methyl vinyl ketone, and four isomers of the methyl butenediols. These gas-phase compounds may serve as precursors for one or more of several compounds detected in the aerosol phase including 2-methylglyceric acid, three 2-methyl alkenetriols, and two 2-methyl tetrols. In contrast to most previous studies, the 2-methyl tetrols (and the 2-methyl alkenetriols) were found to form in the absence of acidic sulfate aerosol. However, reaction conditions did not favor the production of HO 2 radicals, thus allowing RO 2 +RO 2 reactions to proceed more readily than if higher HO 2 levels had been generated. SOA/SOC (i.e. OM/OC) was found to average 1.9 in the absence of NO x . The effective enthalpy of vaporization was measured as 38.6 kJ mol −1 , consistent with values used previously in modeling studies. The yields in this work (usCorrespondence to: T. E. Kleindienst (kleindienst.tad@epa.gov) ing an independent technique than used previously) are lower than those of Kroll et al. (2006) for similar aerosol masses. SOC yields reported in this work range from 0.5-1.4% for carbon masses between 17 and 49 µgC m −3 .

“…However, SOA can be produced from 1,3-butadiene if its oxidation products were to undergo particle-phase oligomerization. Three previous studies have investigated SOA formation from the photooxidation of 1,3-butadiene (Kroll et al, 2005;Angove et al, 2006;Sato, 2008), but the yield and the composition of SOA formed from this reaction remain poorly understood. In this study, we experimentally investigate the formation of SOA from the photooxidation of conjugated dienes in the presence of NO x to improve our understanding of SOA formation from these reactions in urban air.…”

Secondary organic aerosol formation from the photooxidation of isoprene, 1,3-butadiene, and 2,3-dimethyl-1,3-butadiene under high NOx conditions

Abstract. Secondary organic aerosol (SOA) formation from atmospheric oxidation of isoprene has been the subject of multiple studies in recent years; however, reactions of other conjugated dienes emitted from anthropogenic sources remain poorly understood. SOA formation from the photooxidation of isoprene, isoprene-1-13 C, 1,3-butadiene, and 2,3-dimethyl-1,3-butadiene is investigated for high NO x conditions. The SOA yield measured in the 1,3-butadiene/NO x /H 2 O 2 irradiation system (0.089-0.178) was close to or slightly higher than that measured with isoprene under similar NO x conditions (0.077-0.103), suggesting that the photooxidation of 1,3-butadiene is a possible source of SOA in urban air. In contrast, a very small amount of SOA particles was produced in experiments with 2,3-dimethyl-1,3-butadiene. Off-line liquid chromatography -mass spectrometry analysis revealed that the signals of oligoesters comprise a major fraction (0.10-0.33) of the signals of the SOA products observed from all dienes investigated. The oligoesters originate from the unsaturated aldehyde gas phase diene reaction products; namely, semi-volatile compounds produced by the oxidation of the unsaturated aldehyde undergo particle-phase oligoester formation. Oligoesters produced by the dehydration reaction between nitrooxypolyol and 2-methylglyceric acid monomer or its oligomer were also characterized in these experiments with isoprene as the Correspondence to: D. R. Cocker III (dcocker@engr.ucr.edu) starting diene. These oligomers are possible sources of the 2-methyltetrols found in ambient aerosol samples collected under high NO x conditions. Furthermore, in low-temperature experiments also conducted in this study, the SOA yield measured with isoprene at 278 K was 2-3 times as high as that measured at 300 K under similar concentration conditions. Although oligomerization plays an important role in SOA formation from isoprene photooxidation, the observed temperature dependence of SOA yield is largely explained by gas/particle partitioning of semi-volatile compounds.

“…Significant acrolein formation has been observed in the 1,3-butadiene/ozone system, as well as the products formaldehyde, acetaldehyde, propanal, 2-butanone, glyoxal and formic acid [9,10] . The formation of secondary organic aerosol at yields of 0.4-0.5% and having a geometric mean diameter 100 nm has been observed during indoor environmental chamber experiments on 1.0-2.2 ppm 1,3-butadiene in the presence of 0.5-1.1 ppm NO [11] .…”

Abstract. The formation of secondary organic aerosol products from photo-oxidation of 1,3-butadiene and ozone was investigated in static smog chamber. The effects of ozone concentration and relative humidity on the particle formation were studied. Research suggests that with the increase of ozone concentration (0-50 ppm), the particle size of particles larger than 0.7 μm accounted for the proportion of the total number of particles increased and the initial stage of the ozone decomposition rate increased. But the increase in ozone concentration has little effect on the total number of particles. Relative humidity of 4% and 25% of the experimental data show that in the relative humidity of 25%, the initial stage of the ozone decomposition rate is faster and particle size larger than 0.7 μm accounted for a larger proportion of the total number of particles. In the same way, the change in relative humidity has little effect on the total number of particles.
