Abstract :
Smog chamber/FTIR techniques were used to study the Cl atom initiated oxidation of CH3C(O)CH2CH3 in 700–760 Torr of N2 at 296 K. The reaction of Cl atoms with CH3C(O)CH2CH3 proceeds via hydrogen abstraction with 73 ± 9% of reaction occurring at the –CH2– group. Relative rate techniques were used to measure k(Cl + CH3C(O)CHClCH3) = (5.62 ± 0.81) × 10−12 cm3 molecule−1 s−1. It was deduced that the CH3C(O)CHCH3 radical reacts with Cl2 with a rate constant of the order of 10−14 to 10−13 cm3 molecule−1 s−1.
