The gas phase reaction between the CN radical and acetonitrile CH3CN was investigated experimentally with a CRESU apparatus and a slow flow reactor as well as theoretically to explore the temperature and pressure dependence of its rate coefficient from 354 K down to 23 K.

AbstractThe gas-phase reaction of O(3P) atoms with benzene was investigated in a flow system in the pressure range of 50–100mbar and a temperature of 295 ± 2K with a focus on the product formation. O2 concentrations in the carrier gas were in the range of (7.7–84) × 1014 molecule cm−3. The primary stable products detected were phenol, benzene oxide/oxepin and a not identified compound with the probable composition C5H6O. The yields of phenol and benzene oxide/oxepin were 0.12 ± 0.02 and 0.26 ± 0.06, respectively, being not affected by the experimental conditions. For benzene oxide/oxepin, a rapid consecutive reaction with O(3P) atoms was observed with a rate coefficient of k(295K) = (1.1 ± 0.1) × 10−10cm3 molecule−1s−1 measured at a pressure of 100mbar. A substance with the formula C6H6O2 (likely oxepin 4,5-epoxide or oxepin 2,3-epoxide), the isomers of muconaldehyde, as well as formic acid, acrolein and trans-butenedial were identified as products of the reaction of O(3P) atoms with benzene oxide/oxepin.

Good Agreement

The reactions of ozone with 2,3-Dimethyl-2-Butene (CH3)2C=C(CH3)2 and 1,3-Butadiene CH2=CHCH=CH2 have been investigated under atmospheric conditions at 298±3K in air using both relative and absolute rate techniques, and the measured rate coefficients are found to be in good agreement in both techniques used. The obtained results show the addition of ozone to the double bond in these compounds and how it acts as function of the methyl group substituent situated on the double bond. The yields of all the main products have been determined using FTIR and GC-FID and the product studies of these reactions establish a very good idea for the decomposition pathways for the primary formed compounds (ozonides) and give a good information for the effect of the methyl group on the degradation pathways. The results have been discussed from the view point of their importance in the atmospheric oxidation of these pollutants.
