- Abstract
- This paper is concerned with decomposition of heptyl radicals in high temperature combustion environments. Experimental results on the decomposition of n-heptyl iodide in single pulse shock tube studies will be presented. All the products resulting from the decomposition of the 4 heptyl radical isomers are found. This is indicative of the contributions from all possible isomerization and decomposition channels. Analysis of the data show that results are in the region where energy transfer effects must be considered. High pressure rate expressions for the isomerization and decomposition processes are derived. Results are projected to all temperature and pressures. The problems in describing rate constants in the Chemkin format are described.
