Rate Constants for the Gas-Phase Reactions of a Series of C3-C6 Aldehydes with OH and NO3 Radicals
Int J. Chem. Kinet.
79 - 84
Pentanal + ·OH → Products
C2H5COCH3 + ·OH → Products
Pressure: 0.99 bar
2.99x10-11 [±1.9x10-12 cm3/molecule s]
Relative value normalized by a reference value
Static or low flow - Data taken vs time
In real time
Experiments were carried out in a 6500 Liter all Teflon chamber at 296 ?2 K.
OH was generated by the photolysis of CH3ONO at wavelengths above 300 nm in the presence of NO.
The reference reaction was OH + methyl vinyl ketone with accepted k= 2.06E-11 cm3molecule-1s-1.
Indicated errors are two standard deviations and do not include uncertainties in the rate constant of the reference reaction (estimated to be ?10 - 15 %).
