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 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 + cyclohe...

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) × 10⁻²&#8304 cm² molecule⁻¹ near 285 nm. The results are discussed with respect to the literature data.
