✦ Synopsis

The kinetics of the thermal decomposition of acetylacetone has been studied in a shock tube in the temperature range of 1120-1660 K. Detailed analyses of CO and H20 formation data indicate that HzO is formed by a four-center molecular channel, whereas CO is formed by the rapid dissociation of CH3C0 produced by the C-C bond dissociation of acetylacetone. The Arrhenius equations for HzO and CH3C0 formation channels are kz = 1014 2410 21 exp(-60,800 t 1,22O/RT) sec-' and k 3 --10'705'028 exp(-74,600 2 1,68O/RT) sec-', respectively. The results of the study suggest that the six-center molecular channel for the production of acetone and ketene is not important under the condition used in this investigation.
