“…Generally, the values from the present study are in reasonable agreement with those from the Atkinson group 11, 13, 14 and in the case of α‐pinene with those from Ripperton et al 8, Nolting et al 12, and Khamaganov and Hites 15. The reported absolute rate coefficients from Grimsrud et al 10 are all higher by a factor of 1.3 for α‐pinene up to 6.4 for terpinolene.…”

“…The aim of the present study was kinetic investigations for the reaction of O 3 with a series of terpenes (α‐pinene, 3 Δ‐carene, limonene, myrcene, trans ‐ocimene, terpinolene, and α‐terpinene) under flow‐tube conditions using a relative rate technique. For the kinetic parameters, several investigations exist in the literature 8–15. The reported room temperature rate coefficients show a high variability and differ by a factor of three ( 3 Δ‐carene and limonene) up to an order of magnitude (terpinolene and α‐terpinene) making a reinvestigation necessary.…”

The kinetics of the gas-phase reactions of O 3 with a series of selected terpenes has been investigated under flow-tube conditions at a pressure of 100 mbar synthetic air at 295 ± 0.5 K. In the presence of a large excess of m-xylene as an OH radical scavenger, rate coefficients k(O 3 +terpene) were obtained with a relative rate technique, (unit: cm 3 molecule −1 s −1 , errors represent 2σ ): α-pinene: (1.1 ± 0.2) × 10 −16 , 3 -carene: (5.9 ± 1.0) × 10 −17 , limonene: (2.5 ± 0.3) × 10 −16 , myrcene: (4.8 ± 0.6) × 10 −16 , trans-ocimene: (5.5 ± 0.8) × 10 −16 , terpinolene: (1.6 ± 0.4) × 10 −15 and α-terpinene: (1.5 ± 0.4) × 10 −14 . Absolute rate coefficients for the reaction of O 3 with the used reference substances (2-methyl-2-butene and 2,3-dimethyl-2-butene) were measured in a stopped-flow system at a pressure of 500 mbar synthetic air at 295 ± 2 K using FT-IR spectroscopy, (unit: cm 3 molecule −1 s −1 , errors represent 2σ ): 2-methyl-2-butene: (4.1 ± 0.5) × 10 −16 and 2,3-dimethyl-2-butene: (1.0 ± 0.2) × 10 −15 . In addition, OH radical yields were found to be 0.47 ± 0.04 for 2-methyl-2-butene and 0.77 ± 0.04 for 2,3-dimethyl-2-butene.

“…These terpenes have high reactivity with ozone, hydroxyl radicals, and nitrate radicals, which are important species in the troposphere. In order to assess their role in atmospheric chemistry, a considerable number of studies have been carried out on their ambient concentrations [Lonnernan et al, 1978;Seila, 1979;Cronn and Harsch, 1980;Yokouchi et al, 1981Yokouchi et al, , 1983Roberts et al, 1983; Gregory et al, 1986], their emission rates [Tingey et al, 1978[Tingey et al, , 1981Zimmerman, 1979;Flyckt, 1980;Yokouchi and Arnbe, 1984;Lamb et al, 1985Lamb et al, , 1986, and their reactions [Ripperton et al, 1972;Grirnsrud et al, 1975;Winer et al, 1976;Gay and Arnts, 1977;Atkinson et al, 1982Atkinson et al, , 1986Yokouchi and Arnbe, 1985;Gu et al, 1985].…”

Diurnal variations of isoprene and monoterpenes in the atmosphere were precisely measured at an interval of 1–2 hours in the rainy season and in fine midsummer in an agricultural area in Japan. It was observed that the mixing ratio of isoprene was much larger in fine daytime than in nighttime or in cloudy daytime; in contrast, a higher mixing ratio of monoterpenes was usually observed in nighttime. In fine midsummer the concentration of atmospheric isoprene increased gradually after midnight, reaching its maximum late in the afternoon, and decreased rapidly after sunset. The significant difference between atmospheric isoprene and monoterpenes was explained by suggesting that isoprene emission is more strongly affected by temperature and/or solar radiation.

“…Besides this, there is a lack of data on the ozone forming potential of air, as it is found in forests, containing anthropogenic and biogenic hydrocarbons in the ppb range. For further experiments on the photochemical degradation processes of terpenes, a smog chamber was constructed which is optimized for long enclosure times of aerosols to study the reactions of primarily formed condensation nuclei, (which may be formed from the degradation of terpenes (Ripperton et al, 1972)). …”

A smog chamber for studies of the reactions of terpenes and alkanes with ozone and OH

The design and performance of a smog chamber for the study of photochemical reactions under simulated environmental conditions is described. The chamber is thermostated for aerosol experiments, and it comprises a gas chromatographic sample enrichment system suitable for monitoring hydrocarbons at the ppbv level. By irradiating NO x/alkane-mixtures rate constants for the reaction of OH radicals with n-alkanes are determined from n-pentane to n-hexadecane to be (k++_2a)/lO -12 cm 3 at 312K. Rate constants, (k _+ 2a)/10 -17 cm 3 s -l , for the reaction of ozone with trans-2-butene (21.2 _+ 1.0), cis-3-methylpentene-(2) (47.2 _+ 1.7), cyclopentene (62.4_+3.5), cyclohexene (7.8 _+0.5), cycloheptene (28.3 _+ 1.5), c~-pinene (8.6 _+ 1.3), and fl-pinene (1.4 _+ 0.2) are determined in the dark at 297 K using cis-2-bntene (13.0) as reference standard.
