Abstract

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 N~2~ 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^ cm^3^ molecule^−1^ s^−1^. Cyclohexanone has a broad UV absorption band with a maximum cross section of (4.0 ± 0.3) × 10^−20^ cm^2^ molecule^−1^ near 285 nm. The results are discussed with respect to the literature data. © 2008 Wiley Periodicals, Inc. Int J Chem Kinet 40: 223–229, 2008
