Hydrazine Decay in the Atmosphere: Controlled-Environment Chamber Studies and Kinetic Modeling
Abstract
This report documents a series of experiments conducted to shed additional light on the role of surface-catalyzed reactions on the atmospheric oxidation of hydrazine vapor. The experiments were conducted in a controlled- environment chamber consisting of a one-meter diameter stainless steel sphere which is Teflon coated. Vapor-phase hydrazine was introduced into the chamber at the 50-100 ppm concentration level. It was combined with four different synthetic atmospheric mixtures (all at one atmosphere total pressure): dry helium, humid (approx. 75 percent R.H.) helium, 80 percent dry helium plus 20 percent oxygen and 80 percent humid helium plus 20 percent oxygen. A series of experiments were conducted, using the same four synthetic atmospheres listed above, with several types of plates which were placed into a rack in the chamber. These plates included: Teflon-coated aluminum (TCA), black iron (BI), corroded aluminum (CA), and F-16 painted aluminum (PA). The reactivity of the plates towards hydrazine decay was: TAC < BI approx. PA < CA.... Hydrazine, Controlled-environment chamber, FT-IR Spectroscopy, Kinetic modeling, Surface- catalyzed reactions.
