Rate Constants for Reactions of Hydrazine Fuels with O(3P)

Abstract

Room temperature rate constants for the reactions of three hydrazine fuels with O(3P) were measured. A laser-photolysis resonance fluorescence technique was used in the experiments. The reactions were monitored by the decay of 131 nm, O(3S3P) resonance fluorescence under both high pressure (-50 Torr) and low pressure (1 to 3 Torr) conditions. The measured rate constants were 0.99 (+/-0.12 x 10exp-11 cubic cm/molecule for N2 H4, 1.6 (+/-0.34) x 10exp-11 cubic cm/molecule s for CH3HN2H2, and 2.3 (+/-0.34) x 10exp-11 cubic cm/molecule s for (CH3)2N2H2, all at 296K. The rate constants increase with the number of hydrogen atoms per hydrazine molecule. Hydrazine, Rate constant.
