Diels-Alder reactions in high temperature fluids
While free radical reactions are thought to be the primary chemical mechanism for gas phase soot formation at combustion temperatures, Deils-Alder condensation reactions may be important in the formation of cyclic hydrocarbon species leading to aromatic hydrocarbons in pyrolytic-processes at lower temperatures which suffer from carbon formation. In order to evaluate the importance of Diels-Alder reactions in the formation of carbon, accurate kinetic rate data is needed for proper chemical modeling efforts. Diels-Alder reactions have been extensively studied in the gas and liquid phases. Since the reaction is a condensation reaction, the rate constant has a significant pressure as well as a temperature dependence. We report in this paper the results of reaction rate measurements of 1,3-cyclohexadiene with itself. We also report the effect of pressure on the kinetic rate constant for the pressure range 4000-18,000 kPa and the temperature range 200-250/degree/C.
