Advanced B and Al Combustion Kinetics Studies over Wide Temperature Ranges.

Abstract

To help provide a better understanding of the temperature dependence of the kinetics of gas-phase metal oxidation reactions, experimental measurements were made in the 450 to 1750 K temperature regime using a high-temperature fast-flow reactor. The relative concentrations of the metallic species were monitored by laser-induced fluorescence. The following rate coefficient expressions were obtained (in cubic cm, per molecule, per second units): Aluminum + Chlorine Aluminum Chlorine + Chlorine, 7.9 X 10 to the minus 10th power exp(-780 K/T); Al + Hydrochlorine Acid Al Cl + Hydrogen, 1.5 X 10(-10) exp (-800 K/T); AlCl + Cl2 AlCl, 9.6 X 10 to the minus 11th power exp (-610 K/T); AlCl + Carbon Dioxide Oxy Aluminum Chloride + Co. To allow product identification in the latter and other reactions and make measurements on reactions of larger than diatomic radicals, a second reactor facility, in which the metallic species will be monitored by mass spectrometry, was designed. The construction of this facility nears completion.
