Abstract : Dodecane, a model hydrocarbon for jet fuels, and five other hydrocarbons, tetralin, 1-tridecene, cis- and trans-decalin, and indane were subjected to chemiluminescence analysis during their oxidation. Studies were carried out on both the pure compounds and on each as a 5% additive in dodecane. Activation energies were obtained for initiation and propagation steps of the oxidation process, which were previously unavailable and contribute toward a better understanding of the oxidation mechanism. In particular, the chemiluminescence analysis identified the importance of a unimolecular propagation process prevalent during the high temperature oxidation of dodecane, 1-tridecene, and cis-decalin. The measurements were carried out utilizing a chemiluminescence apparatus specially designed for such measurements at elevated temperatures (100-400C). Methodology for its use was developed.
