Atmospheric chemistry of cyclohexanone: UV spectrum and kinetics of reaction with chlorine atoms...

Absolute and relative rate techniques were used to study the reactivity of Cl atoms
with cyclohexanone in 6 Torr of argon or 800–950 Torr of N2 at 295 ± 2 K. The absolute
rate experiments gave k(Cl + cyclohexanone) = (1.88 ± 0.38) × 10−10, whereas the relative
rate experiments gave k(Cl + cyclohexanone) = (1.66 ± 0.26) × 10−10 cm3 molecule−1 s−1.
Cyclohexanone has a broad UV absorption band with a maximum cross section of (4.0 ± 0.3)
× 10−20 cm2 molecule−1 near 285 nm. The results are discussed with respect to the literature
data.
