METHODS FOR ELIMINATION OF CORROSION PRODUCTS OF NITROGEN TETROXIDE

Abstract

Second quarter progress is reviewed on a 12-month program to ascertain methods for the elimination of the corrosion products in N2O4 (iron- nitrate-containing species) which are responsible for the phenomenon of 'flow decay.' Studies on the rate and mechanism of solution of iron in anhydrous N2O4 are described. Nuclear magnetic resonance and electron resonance spectroscopy studies of the solvated iron nitrate species are presented. Compounds of the type Fe(NO3)3.xN2O4 have been synthesized and purified. The properties of these materials have been found to match the properties of the flow decay substance. Solubility studies of the 'synthetic' flow decay material in anhydrous N2O4, N2O4 containing NO, and N2O4 containing small quantities of H2O4 have been initiated and are discussed in detail. Preliminary experiments have indicated possible candidate coordinating agents for further investigation. A flow bench designed to study this phenomenon is being constructed. Design considerations are discussed.
