Products of the Hypochlorite Oxidation of Hydrazine Fuels
Abstract
Neutralization of hydrazine fuels with hypochlorite is a recommended procedure for the treatment of fuel spills prior to disposal. Previous research has shown that incomplete reaction of hypochlorite with the methylated hydrazine fuels monomethylhydrazine (MMH) and unsymmetrical dimethylhydrazine (UDMH) leads to a wide variety of byproducts, including N-nitrosoamines, which are believed to be highly carcinogenic. The results presented in this report were obtained as part of a program to assess the environmental implications of using the hypochlorite method for the treatment and disposal of hydrazine fuel spills. The fuels examined were hydrazine, MMH, UDMH, and Aerozine-50. The neutralization products were determined under experimental conditions comparable to those expected for actual spills. The effects of varying the temperature and the pH as well as of aging the final reaction mixture were determined. Quantitative measurements of the nitrosoamines produced are presented. Major and environmentally significant minor products were identified using gas chromatography/mass-spectrometry. Keywords: Chemical reaction. Hydrazine; Monomethylhydrazone (MMH); Unsymmetrical dimethylhydrazine (UDMH).
