Production of radicals in the ozonolysis of propene in air
Abstract Radical production in the ozonolysis of propene in air was monitored directly by a peroxy radical chemical amplification (PERCA) instrument at room temperature (298±2 K) and atmospheric pressure (1×$ 10^{5} $ Pa). The ozonolysis reactions were conducted in a flow tube under pseudo-first-ord...

| 520 | |a Abstract Radical production in the ozonolysis of propene in air was monitored directly by a peroxy radical chemical amplification (PERCA) instrument at room temperature (298±2 K) and atmospheric pressure (1×$ 10^{5} $ Pa). The ozonolysis reactions were conducted in a flow tube under pseudo-first-order conditions for ozone. The decay in ozone was calculated based on reaction time tr and effective rate constant keff (keff = k1[$ C_{3} $$ H_{6} $]0)) for the ozone-propene reaction. The total radical yields relative to consumed ozone were determined to be 0.97±0.17 (σ). A box model was used to simulate radical production in the ozone-propene reaction. The model-derived radical yields agree well with those from experiment within the uncertainty of the two methods. In addition, the yields for OH, $ HO_{2} $ and $ CH_{3} $$ O_{2} $ were obtained from the measured total radical yields and radical partitioning derived from the box model. The yield is 0.39±0.08 (σ) for OH, 0.19±0.04 (σ) for $ HO_{2} $, and 0.39±0.08 (σ) for $ CH_{3} $$ O_{2} $. This work suggests that the previously measured radical yield by indirect method for the ozonolysis of propene may be underestimated. | ||

The total radical yields relative to consumed ozone were determined to be 0.97±0.17 (σ). A box model was used to simulate radical production in the ozone-propene reaction. The model-derived radical yields agree well with those from experiment within the uncertainty of the two methods. In addition, the yields for OH, $ HO_{2} $ and $ CH_{3} $$ O_{2} $ were obtained from the measured total radical yields and radical partitioning derived from the box model. The yield is 0.39±0.08 (σ) for OH, 0.19±0.04 (σ) for $ HO_{2} $, and 0.39±0.08 (σ) for $ CH_{3} $$ O_{2} $. This work suggests that the previously measured radical yield by indirect method for the ozonolysis of propene may be underestimated.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">yield</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">radical</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">ozonolysis</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">propene</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">PERCA</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Yang, Bing</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wang, ZhuQing</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Yang, HongYan</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Liu, Lu</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Science in China / B</subfield><subfield code="d">SP Science in China Press, 1989</subfield><subfield code="g">52(2009), 3 vom: 22.

Production of radicals in the ozonolysis of propene in air |
| abstract |
Abstract Radical production in the ozonolysis of propene in air was monitored directly by a peroxy radical chemical amplification (PERCA) instrument at room temperature (298±2 K) and atmospheric pressure (1×$ 10^{5} $ Pa). The ozonolysis reactions were conducted in a flow tube under pseudo-first-order conditions for ozone. The decay in ozone was calculated based on reaction time tr and effective rate constant keff (keff = k1[$ C_{3} $$ H_{6} $]0)) for the ozone-propene reaction. The total radical yields relative to consumed ozone were determined to be 0.97±0.17 (σ). A box model was used to simulate radical production in the ozone-propene reaction. The model-derived radical yields agree well with those from experiment within the uncertainty of the two methods. In addition, the yields for OH, $ HO_{2} $ and $ CH_{3} $$ O_{2} $ were obtained from the measured total radical yields and radical partitioning derived from the box model. The yield is 0.39±0.08 (σ) for OH, 0.19±0.04 (σ) for $ HO_{2} $, and 0.39±0.08 (σ) for $ CH_{3} $$ O_{2} $. This work suggests that the previously measured radical yield by indirect method for the ozonolysis of propene may be underestimated. © Science in China Press and Springer-Verlag GmbH 2009 |
