Abstract

1,5โ€cyclooctadiene or 4โ€vinylcyclohexene mixture diluted with argon was heated to temperatures in the range 880โ€“1230 K behind reflected shock waves. Profiles of IRโ€laser absorption were measured at 3.39 ฮผm. From these profiles, rate constants k~1~ and k~2~ for the decyclization reactions 1,5โ€cyclooctadiene โ†’ biradical and 4โ€vinylcyclohexene โ†’ biradical were evaluated as k~1~ = 5.2 ร— 10^14^ exp(โˆ’48.3 __k__cal/RT) s^โˆ’1^ and k~2~ = 3.5 ร— 10^14^ exp(โˆ’55.3 __k__cal/RT) s^โˆ’1^, respectively. ยฉ 1993 John Wiley & Sons, Inc.

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
